User Interfaces are crucial components that enable enhanced customer experience.Building an Android User Interface (UI) is not an easy task. XML layouts can be verbose and difficult to maintain. And it can be hard to make changes to the look and feel of the <a class="link" href="https://m2pfintech.com/blog/super-apps-in-consumer-banking-what-role-does-open-banking-play/">mobile app</a> without rewriting layouts. Many developers still grapple with complexities in XML layouts, code volumes, and spend hours on tedious UI updates.Is there a way you can build better Android UIs with less code?Jetpack Compose holds the answer.In this blog, our resident Android Expert and Software Development Engineer <a class="link" href="https://www.linkedin.com/in/sagarbalyan/">Sagar Balyan</a> explains what Jetpack Compose is, its benefits, and how it is transforming Android UI development by overcoming the limitations of the traditional approach.<h2 class="heading-node" id="9sz77xr8f" style="text-align: justify">What is Jetpack Compose?</h2>Jetpack Compose is the cutting-edge toolkit for building native UI in Android. It simplifies and speeds up UI development allowing you to bring your apps to life with minimal code, a robust set of tools, and user-friendly Kotlin <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">API</a>s.Jetpack Compose is declarative, meaning you can describe how your UI should look like, rather than how it should be built, making it much easier to create complex layouts with maintainable code. Its speed and ease of use have quickly made it the preferred choice of technology for Android development.Now, let’s explore the benefits that Jetpack Compose brings to the table.<h3 class="heading-node" id="0fkwz62xu" style="text-align: justify">Less Code</h3>Less code is the new norm, thanks to Jetpack Compose. By eliminating XML files, it simplifies the development process and eliminates unnecessary complexity. It's no wonder that even Twitter has applauded its low code feature, highlighting how the code required for a Button class was dramatically reduced by 10X.<h3 class="heading-node" id="neh0tnq7w" style="text-align: justify">Faster Development</h3>Jetpack Compose not only accelerates the Android app development process but also makes it faster and more efficient. With its intuitive and declarative syntax, developers can build user interfaces in a fraction of the time compared to traditional approaches. Additionally, Jetpack Compose simplifies the implementation of light and dark modes in apps, making it easier to create visually appealing and consistent experiences across different themes.<h3 class="heading-node" id="qcy4oaro2" style="text-align: justify">Live Previews</h3>Jetpack Compose can provide live previews and is not just limited to just one. Developers can create and preview multiple composables live previews in real-time, allowing for seamless experimentation and instant visual feedback. This powerful feature enables developers to iterate and refine their UI components quickly, leading to more efficient and effective development cycles.<h3 class="heading-node" id="qbozuvyso" style="text-align: justify">Powerful</h3>Jetpack Compose can help you build stunning apps by providing direct access to the Android platform APIs and seamless integration with essential features like material design, dark theme, and animations. This powerful toolkit has garnered the attention of industry leaders like Square, who have declared that Compose goes beyond just offering a declarative UI. It has significantly improved accessibility APIs, layout capabilities, and various other aspects of app development.<h3 class="heading-node" id="8gshymfhu" style="text-align: justify">Separation of Concern</h3>Other than these benefits, Jetpack Compose addresses a barrier that was present in the traditional XML approach namely the Separation of Concern. For example, when a Viewmodel was written in Kotlin, it had a close interaction with the XML file. This tight coupling between the Viewmodel and the XML file caused increased dependencies.If these components are tightly coupled and heavily dependent on each other, it defeats the purpose of having two separate files. However, Jetpack Compose resolves this problem by allowing the UI to be written directly in Kotlin. This means that the Viewmodel and the UI are now seamlessly integrated, reducing dependencies and enhancing code organization. With Jetpack Compose, developers can achieve a more cohesive and efficient development workflow.Due to these wide-ranging benefits, more companies are transitioning from the traditional XML approach and embracing this modern toolkit.<h3 class="heading-node" id="hzgcqsw3y" style="text-align: justify">Live Jetpack Compose Apps</h3>Wonder what live apps have been built on Jetpack Compose?Here are a few. If you are not using them already, make sure you explore them further.<ul class="list-node" id="chyc6t16f"><li><a class="link" href="https://play.google.com/store/apps/details?id=com.airbnb.android&amp;hl=en&amp;gl=US&amp;pli=1">Airbnb</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=me.lyft.android&amp;hl=en&amp;gl=US">Lyft</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=com.reddit.frontpage&amp;hl=en&amp;gl=US">Reddit</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=in.startv.hotstar&amp;hl=en&amp;gl=US">Disney + Hotstar</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=com.twitter.android&amp;hl=en&amp;gl=US">Twitter</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=in.swiggy.android&amp;hl=en_IN&amp;gl=US">Swiggy</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=com.soundcloud.android&amp;hl=en_IN&amp;gl=US">Soundcloud</a></li><li><a class="link" href="https://www.dropbox.com/install">Dropbox</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=com.bumble.app&amp;hl=en_IN&amp;gl=US">Bumble</a></li><li><a class="link" href="https://play.google.com/store/apps/details?id=com.grabtaxi.passenger&amp;hl=en&amp;gl=US">Grab</a></li></ul><h2 class="heading-node" id="qa3n1xr2j" style="text-align: justify">Code Snippet Implementation</h2>To use Compose effectively, it's essential to have the following code snippet properly implemented in projects.

How to Create Stunning UIs for Android with Jetpack Compose

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/04/Penetration-testing-banner1.webp" alt="M2P Fintech" title="" width="100%" height="253">The $158.9 billion fintech industry thrives on mobile apps. Android dominates the mobile app market with a whopping 71.65% market share. Though in demand globally, its open-source&nbsp;nature makes data security a vulnerability in Android apps. Even <a class="link" href="https://m2pfintech.com/blog/super-apps-in-consumer-banking-what-role-does-open-banking-play/">super apps</a> are no exception.&nbsp;Developing and releasing a fully functional and secure Android application is a critical challenge for app developers. Managing app functionality is the easy part; but the real challenge is making the Android application secure and resilient to cyberattacks. &nbsp;What’s the best way to do this?&nbsp;Our Software Development Engineer, <a class="link" href="https://www.linkedin.com/in/sundaramanikandan-l-80957014b/">Sundaramanikandan</a> has hands-on experience in developing highly secure Android apps and will take us through every step in mitigating cyberattacks while developing an app. &nbsp;First things first, every developer must prioritize security to protect users and their data. The security-first approach will benefit the 6.92 billion smartphone users in the world, who constitute over 86.29% of the global population.&nbsp;&nbsp;Remember that the advances in digitization and technology also apply to hackers and cybercriminals. Technology that makes lives easier has increased our exposure to risks. Fraudsters ride on the vulnerabilities by using more sophisticated techniques to exploit loopholes and evade detection while breaking into systems to access sensitive data.&nbsp;<h2 class="heading-node" id="sdulm87wi" style="text-align: justify">How to secure Android devices from attackers?&nbsp;</h2>Developers and organizations need to deploy secure software development lifecycle practices to protect against data breaches or theft. Public Wi-Fi networks and other wireless communication systems should be blocked to prevent man-in-the-middle attacks and other unsecured communication exploits. Attackers can pretend to be real web services, steal data, or listen in on calls and texts by taking over a user's mobile signal.&nbsp;<h2 class="heading-node" id="d5lk42h71" style="text-align: justify">Smartphone rooting to get superuser permissions&nbsp;&nbsp;&nbsp;</h2>Firstly, the process called rooting is done, i.e., removing the limitations on a mobile or tablet running the Android operating system. It lets you get root access to the code of the Android operating system (the equivalent term for Apple devices is jailbreaking). It gives permission to change the device's software code or install software that the manufacturer wouldn't normally let us do.&nbsp;<h2 class="heading-node" id="oj87o5xpb" style="text-align: justify">Cons of running apps on a rooted device&nbsp;</h2>Simply put, it opens higher risks like spoofing, cheating, and abuse of core functionalities. A root-level app can easily set up backdoors that let unauthorized users get into the device and then into the secure corporate network. When you "root" your Android device, you give apps unauthorized access to your operating system and sensitive data. It further leads to the theft of user data, finances, intellectual property, and piracy. Some malware apps specifically go after rooted devices to infect system-level files. So, you must be careful what you install.&nbsp;Targeted cyberattacks on corporates are on the rise as more and more business transactions are done on mobile devices. Rooted Android devices make it easier to sneak into the corporate network. For a financial app, if an attacker can intercept a network call and change the address, the victim could lose a lot of money, and the company that developed the app will lose its reputation.&nbsp;As having a user-friendly mobile app is a key differentiator, banks and financial institutions are in a dilemma to choose between allowing their app, which contains excellent payment functionalities and extremely sensitive data, to run on rooted/jailbroken devices or risk losing their target audience. Or they can opt for the middle ground by mitigating the risks of the app running on rooted devices. This compromise is critical. Or else, risks such as malware, man-in-the-middle attacks, and system API hijacking could lead to user data exfiltration. &nbsp;Therefore, Android app installation must be blocked on rooted devices to prevent attacks specifically targeting users who have rooted their smartphones.&nbsp;<h2 class="heading-node" id="78wzaxox3" style="text-align: justify">How can app developers block Android installation on a rooted device?&nbsp;</h2>Every Android app developer should understand the following pointers below to steer clear of the hazards of rooted devices.&nbsp; What’s the common way an app can be tampered with?&nbsp;<ol class="list-node" id="lwmuzqjzn"><li>ByPassing root detection logic implemented&nbsp;&nbsp;</li><li>ByPassing the SSL Pinning&nbsp;</li></ol>What are the commonly used hacking tools?&nbsp;<ol class="list-node" id="tym0kml1c"><li>Magisk&nbsp;</li><li>LSXposed Framework&nbsp;</li></ol>Dos and Don’ts - for infosec clearance to block Android app installation&nbsp;Don’ts&nbsp;❌ Install the app on a rooted device&nbsp;❌ Tapjack&nbsp;❌ Copy/paste sensitive data&nbsp;❌ Take screenshots&nbsp;&nbsp;Dos&nbsp;Now, the following method will help create the most comprehensive approach:&nbsp;✅ Check if the app is running in emulator&nbsp;This is the first thing we need to look at when the app is launched. If a hacker extracts the APK and tries to run it in an emulator/simulator, we should stop running the app if it is a production version. This functionality can be built as an extension function and utilized in the application's base activity.&nbsp;<pre class="block-node"><code>val isRunningOnEmulator: Boolean by lazy {
&nbsp;&nbsp;&nbsp; // Android SDK emulator
&nbsp;&nbsp;&nbsp; return@lazy ((Build.FINGERPRINT.startsWith(“google/sdk_gphone_”)

}&nbsp;

✅ Check developer options&nbsp;

Hooking an app is as simple as enabling the developer settings on the device and connecting to the Android SDK tool. Hence, when the app is launched, we must determine whether the developer option is enabled or not by writing an extension function.&nbsp;

fun isDevMode(context: Context): Boolean {&nbsp;
&nbsp;&nbsp;&nbsp; return when {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Build.VERSION.SDK_INT &gt; Build.VERSION_CODES.JELLY_BEAN -&gt; {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.getInt(&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; context.contentResolver,&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Global.DEVELOPMENT_SETTINGS_ENABLED, 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ) != 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Build.VERSION.SDK_INT == Build.VERSION_CODES.JELLY_BEAN -&gt; {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Suppress(“DEPRECATION”)&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.getInt(&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; context.contentResolver,&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ) != 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; else -&gt; false&nbsp;
&nbsp;&nbsp;&nbsp; }&nbsp;
}&nbsp;

✅ Check if the device is rooted&nbsp;&nbsp;

The Util class is commonly used to determine whether a device is rooted, or the super user “SU” is enabled.&nbsp;

private val binaryPaths = arrayOf(
&nbsp;&nbsp;&nbsp; “/data/local/”,
&nbsp;&nbsp;&nbsp; “/data/local/bin/”,
&nbsp;&nbsp;&nbsp; “/data/local/tmp/”,
&nbsp;&nbsp;&nbsp; “/data/local/xbin/”,
&nbsp;&nbsp;&nbsp; “/sbin/”,
&nbsp;&nbsp;&nbsp; “/su/bin/”,
&nbsp;&nbsp;&nbsp; “/system/bin/”,
&nbsp;&nbsp;&nbsp; “/system/bin/.ext/”,
&nbsp;&nbsp;&nbsp; “/system/bin/failsafe/”,
&nbsp;&nbsp;&nbsp; “/system/sd/xbin/”,
&nbsp;&nbsp;&nbsp; “/system/usr/we-need-root/”,
&nbsp;&nbsp;&nbsp; “/system/xbin/”,
&nbsp;&nbsp;&nbsp; “/system/app/Superuser.apk”,
&nbsp;&nbsp;&nbsp; “/cache”,
&nbsp;&nbsp;&nbsp; “/data”,
&nbsp;&nbsp;&nbsp; “/dev”,

&nbsp;&nbsp;&nbsp; “/sbin/su”,
&nbsp;&nbsp;&nbsp; “/system/bin/su”,
&nbsp;&nbsp;&nbsp; “/system/xbin/su”,
&nbsp;&nbsp;&nbsp; “/data/local/xbin/su”,
&nbsp;&nbsp;&nbsp; “/data/local/bin/su”,
&nbsp;&nbsp;&nbsp; “/system/sd/xbin/su”,
&nbsp;&nbsp;&nbsp; “/system/bin/failsafe/su”,
&nbsp;&nbsp;&nbsp; “/data/local/su”,
&nbsp;&nbsp;&nbsp; “/su/bin/su”,
&nbsp;&nbsp;&nbsp; “./frida-server”,
&nbsp;&nbsp;&nbsp; “/data/local/tmp/frida-server”

)&nbsp;

&nbsp;When this class is called upon app launch, it checks to see whether any of the aforementioned binaries are present on the device and returns “rooted” if any are.&nbsp;

✅ Integrate root detection library like RootBear&nbsp;

RootBear is a popular open-source library that can be utilized in our app to detect root causes.&nbsp;

implementation ‘com.scottyab:rootbeer-lib:0.1.0′&nbsp;

After adding this library in the app build Gradle file, it can be implemented in a base activity like:&nbsp;

if (!BuildConfig.DEBUG &amp;&amp; rootBeer.isRooted) {
&nbsp;&nbsp;&nbsp; showRootedDeviceDialog(getString(R.string.device_rooted))
&nbsp;&nbsp;&nbsp; isRootedDeviceBool = true
} else if (!BuildConfig.DEBUG &amp;&amp; rootBeer.isRootedWithBusyBoxCheck) {
&nbsp;&nbsp;&nbsp; showRootedDeviceDialog(getString(R.string.device_rooted))
&nbsp;&nbsp;&nbsp; isRootedDeviceBool = true
}&nbsp;&nbsp; 
</code></pre>Now, all the steps discussed around a great way to prevent an Android app from being installed or functioning on a rooted device. &nbsp;But this is not all. There is more.&nbsp;There is another tool called ‘Frida’ that helps bypass all the above logics implemented in an app.&nbsp;Want to know how to block Frida?&nbsp;Stay tuned to our next blog!&nbsp;This article is authored by&nbsp;<a class="link" href="https://www.linkedin.com/in/sundaramanikandan-l-80957014b/">Sundaramanikandan.</a><a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://m2pfintech.com/newsletter/" target="_blank" rel="noreferrer noopener">Subscribe</a>&nbsp;to our newsletter and get the latest fintech news, views, and insights, directly to your inbox.Follow us on&nbsp;<a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://www.linkedin.com/company/m2pfintech/mycompany/" target="_blank" rel="noreferrer noopener">LinkedIn</a>&nbsp;and&nbsp;<a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://twitter.com/m2pfintech" target="_blank" rel="noreferrer noopener">Twitter</a>&nbsp;for insightful fintech tales curated for curious minds like you.

And the average cost of a data breach hit an all-time high of $4.35 million this year.Since the pandemic, people’s social and financial lives have gone digital. More than 2.5 quintillion bytes of data are generated every second across categories and channels. Imagine this quantum of information falling into the wrong hands due to compromised login credentials, phishing attacks, and cloud misconfigurations. It could expose consumers and businesses to financial loss, reputational damage, operational disruptions, and legal repercussions.As data is one of the most valuable assets a financial organization can possess, securing the data environment from the risk of cyber threats, data breaches, and other attacks is critical.So how can financial companies secure their data environment?Using ISMS.<h2 class="heading-node" id="ljb3adzqe" style="text-align: justify">How ISMS enables a secure environment?</h2>Financial organizations need a robust Information Security Management System (ISMS) to avoid threats and secure sensitive data. ISO 27001 &amp; ISO 22301 certifications are imperative to ensure data environments are secure without data exfiltration and unauthorized data manipulation. ISMS compliance prevents financial penalties, reputation loss, and legal and regulatory non-compliance.<h2 class="heading-node" id="8nwndysxz" style="text-align: justify">What is ISMS?</h2>ISMS is a framework that improves data security by protecting all forms of information, viz., digital, paper-based, and other cloud devices. It establishes a systematic approach that maintains an organization’s confidentiality, integrity, and availability.<ul class="list-node" id="pogyjzt23"><li>Confidentiality- ensuring the right access control</li><li>Integrity -keeping data complete and accurate at all times</li><li>Availability -making sure data is accessible anytime as required</li></ul>The ISMS framework comprises policies, processes, and controls that protect organization data and increase attack resilience. Businesses can leverage their risk analysis approach to reduce costs associated with adding layers of defense technology that might not always work.<h2 class="heading-node" id="jmwuobn5t" style="text-align: justify">Avert security threats with ISO 27001&nbsp;standard</h2>Security threats apply not just to IT assets. Non-IT data sets are under significant threat too. Financial companies need to be proactive with ISO 27001 compliance to secure all data assets, manage data privacy and integrity and ensure customer confidence.ISO 27001 is a security management standard that helps an organization manage risk factors that may include procedures, policies, and staff training. The international standard ISO/IEC 27001 comprises guidelines jointly established by the International Electrotechnical Commission (IEC) and International Organization for Standardization (ISO).The ISO 27001 standard relies a lot on regular risk assessments. These assessments ensure that the organization is so prepared and secure, that when threats appear, all the appropriate measures are already laid out. The ISO 27001 standard encompasses deep risk assessment processes, information classification, organizational structuring, monitoring and reporting guidelines, information security policies, and access control mechanisms, among other procedures.<h2 class="heading-node" id="q2yipzw0r" style="text-align: justify">Combat disruptions with ISO 22301&nbsp;standard</h2>In case of untoward incidents and natural disasters, there is often little or no time for businesses to prepare a proper response. This leads to disruption between people, processes, networks, and infrastructure.Financial companies need to combat data attacks during unexpected times to stay out of financial loss, secure customer confidence, manage customer loyalty and operate their business smoothly. This is precisely what ISO 22301 solves for. ISO 22301 mitigates risks and helps an organization tide over vulnerabilities.ISO 22301 is a global standard published by the International Organization for Standardization (ISO) for Business Continuity Management Systems (BCMS). This business continuity management standard helps an organization identify threats, respond to them, and recover quickly with the least disruption to their business.<h2 class="heading-node" id="md4logi7j" style="text-align: justify">Top-notch data security, our priority</h2>Certified under ISO 27001 and ISO 22301 standards, we prioritize data environment security to defend against cyber-attacks, data breaches, and other risks.

Securing Data Environments with ISMS

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/06/Flutter-for-Fintech_Blog-banner_04.webp" alt="M2P Fintech" title="" width="100%" height="284">Fintech has transmuted banking and financial operations worldwide. It has radically simplified financial services and processes with the help of banking applications. Back in the day fintech applications were confined only to tech-savvy users, but today, it has become an integral part of life for all generations. The appetite for mobile-first, customized financial applications is driving fintech companies to innovate and consistently deliver advanced products and services.Banking applications are traditionally built for specific operating systems and <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a> using the respective native programming languages/technologies. But these practices resulted in higher cost implications and prolonged time to market. To overcome such limitations, fintechs adopted the latest digital innovations to power personalization, user engagement, and security.The launch of Flutter in 2017 changed the dynamics of application development as it provided a great user experience tailored for specific operating systems. This unique feature made Flutter the holy grail of fintech app development. Over the last few years, several companies have successfully launched their applications using the Flutter framework.Curious to know how to add a flutter module to an existing android and iOS application?You’re in luck. We have our domain expert and Senior Software Engineer,&nbsp;<a class="link au lh" href="https://www.linkedin.com/in/chinnadurai-viswanathan-b2b6b7a5/" target="_blank" rel="noopener ugc nofollow">Chinnadurai Viswanathan</a>&nbsp;share the nitty-gritty of how Flutter can be used in fintech applications.Here are the topics he sheds light upon.<a class="link" href="#430e">What is Flutter?</a><a class="link" href="#d14a">Why Flutter is critical to Fintech?</a><a class="link" href="#fb14">How to Generate a Flutter Module?</a><a class="link" href="#69a3">Android Integrations</a><a class="link" href="#af8c">IOS Integrations</a>Here you go!<h2 class="heading-node" id="ag0mm47r9">What is Flutter?</h2>Flutter is an open-source software development kit from Google. It is used to build cross-platform applications, including mobile, web, and embedded products &amp; services. Programmers employing Flutter write a single codebase to create applications that run across various platforms such as android, iOS, Windows, and Linux. Developers build a Flutter app once and cross-compile them for multiple platforms with Flutter instead of creating an individual application for each platform.Let us be clear here that Flutter is not a programming language. It is a User Interface (UI) framework that works on the Dart programming language. It uses native UI elements which can be personalized during development. Some of the most used Flutter applications are Google Pay, Xianyu by Alibaba, and the KenKen puzzle app.<h2 class="heading-node" id="d14a">Why is Flutter critical to Fintech?</h2>Flutter combines the best features from native and hybrid application development approaches. Therefore, it is considered an optimal solution for neo banks and fintech companies. The Flutter framework offers manifold benefits to the user. But in this article, we emphasize the ones that are most essential for developing a fintech or mobile banking solution. Application and Data SecurityFlutter is powered by Dart and compiled into a native, computer-executable code. There are no intermediary apps required. This makes Flutter-based banking apps more secure than native solutions. Moreover, it also involves a comprehensive native library and changes data formats during compilation. So, the reverse engineering process is multifaceted, making it almost impossible for hackers to comprehend the software functionality to reproduce.Information security and compliance with regulations like <a class="link" href="https://m2pfintech.com/blog/pci-dss-the-payments-armour/">PCI DSS</a> and GDPR are imperative for a banking application. The framework allows biometric authentication via Face ID or Touch ID, and enables Dart developers to leverage the recently released library implementations of all popular data encryption algorithms. This boosts the security of the customers’ personal and financial data as well as transaction details.Reliable PerformanceAn application’s performance is directly proportional to customer engagement and retention rate. Delays in loading time significantly impact the product’s performance, which can make the customers stop using the application again.Flutter can offer up to 120 frames per second (FPS) performance, making it a top choice for banking apps that serve a colossal userbase with rapid response time.Use of Declarative APIFlutter harnesses reactive declarative UI <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a>. This means Flutter’s user interface reflects the current state of the application. For example, if a user flips a switch in the settings screen, it triggers a redraw of the current state, and the UI rebuilds from scratch. This is the key advantage of Flutter.There is only one code path for any state of the user interface. The developer describes what the UI should be like, for any given state once, and that is it. The framework handles the arduous, error-prone task of optimizing the UI.Saves Time, Cost, and EffortUnlike native technologies, the Flutter framework presents a unique feature called the&nbsp;Hot Reload. It allows the developers to see the front-end and back-end changes in real-time. This enhances the product delivery speed as it saves a lot of time involved in developing and compiling a banking app. Additionally, Flutter offers a lot of widgets that help in simulating the behavior of various design languages, thus enabling the developers to jump some of the tedious steps in the application development.Furthermore, by using Flutter, developers write only one codebase for different operating systems. Thus multiple teams for each operating system is not required. This reduces the time and effort involved in testing bugs and potential issues. Furthermore, the use of a single codebase for different platforms drastically alleviates the maintenance process and, in turn, minimizes operational costs.Delivers Seamless User Experience and PerformanceReleasing new features and updates according to end-user feedback is the key to boosting customer engagement and retention. Flutter is flexible and has an in-built application builder. The developers can take advantage of a wide range of pre-developed, reusable UI elements to customize and fit customer needs and specifications. The apps built using this framework facilitate seamless user experience and superior performance.<h2 class="heading-node" id="fb14">How to Generate a Flutter Module?</h2>To create a flutter project, you require one of the following channels: beta, dev, or master.

The Implications of Flutter in Fintech

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/05/Hardware-Security-Modules-01-1.webp" alt="M2P Fintech" title="" width="100%" height="284">Security compliance is non-negotiable. No matter what.Irrespective of whether you are into digital banking, card issuance, or <a class="link" href="https://m2pfintech.com/blog/digital-lending-open-credit-enablement-network/">lending</a>, you must remember that your customer data, credentials, and documents are vulnerable to security hazards. Without strong <a class="link" href="https://m2pfintech.com/blog/why-is-risk-based-authentication-rba-critical-for-banks/">risk management</a> measures, you may risk exposing yourself and your customers to data breaches, cyber-attacks, and exorbitant fines from regulatory authorities. This is where cryptography, the science of protecting sensitive data saves the day, by delivering the highest levels of data protection.<h2 class="heading-node" id="q22mmnm3s">Cryptographic Keys</h2>Cryptography uses digital keys to encrypt and decrypt data with required levels of complexity for secure access and compliant operations.So, what is a cryptographic key?A cryptographic key refers to a string of characters in an encryption algorithm that helps randomly create the desired data. This key helps convert a plain text to ciphertext and vice-versa whenever data encryption and decryption happens. Efforts must ensure that only the authorized user has access to the key. The encrypted data must be stored securely for decryption without any discrepancy.<h2 class="heading-node" id="5d58">Lifecycle of a Cryptographic Key</h2> The following process comprises the cryptographic key lifecycle.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/05/Hardware-Security-Modules-02.webp" alt="M2P Fintech" title="" width="100%" height="285">Provisioning -The provisioning process generates keys using a key management system, an hardware security module (HSM), or a Trusted Third Party (TTP) through random number generators. The keys should be strong enough to provide the necessary protection to secure the data.Backup and storage-&nbsp;This is a critical step where a secure backup copy of the key is made. It should be available for future retrieval if the key undergoes any failures. Such backup keys are often stored in external media or other backup solutions. All private keys must be encrypted before being stored.Deployment-&nbsp;The&nbsp;new key is installed electronically or manually into a secure cryptographic devices such as Hardware Security Module.Management, Monitoring, and Rotation-&nbsp;Here, the keys are often controlled and monitored with respect to the industry standards and policies. The encryption key management system handles key rotation and deploys new keys as and when existing keys expire.Archiving-&nbsp;The keys that are no longer in operation are stored here for an extended period. They might be required again in the future for associated data retrieval. The key, when archived, is encrypted for additional security.Disposal-&nbsp;The keys are permanently destroyed here, when they are no longer needed. Before destruction, the key is analyzed and sometimes recovery is processes if necessary. A key can be removed from its operation using key destruction, key deletion, or key termination.Generating, securing, and managing cryptographic keys can be multifaceted and complex, requiring support from information security and development teams.So, how can you create, monitor, store, and optimally use cryptographic keys?Simple. Install HSM.<h2 class="heading-node" id="a893">So, what is Hardware Security Module (HSM)?</h2>Hardware Security Module (HSM) is a device that provides a wired security solution for the wireless world. It is a dedicated cryptographic processor that offers a secure, tamper-resistant environment specifically designed to protect identities, devices, and cryptographic key data throughout its lifecycle.HSM protects any data in use, transit, and rest, for encryption, decryption, authentication, and key management. In toto, it serves as a ‘trust anchor’ to ensure compliance, simplify audits, generate, and store keys.<h2 class="heading-node" id="6380">Types of HSMs</h2>HSMs can be broadly classified (as listed below) based on the levels of functionality and compliance with different security standards.· General Purpose (GP) HSM· Transaction HSMGeneral Purpose (GP) HSMWherever there is sensitive data, and the need for encryption prevails, GP HSM is indispensable.

Cryptographic Keys and Hardware Security Modules - An Introduction

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/05/Artboard-1-copy-8-2-2.webp" alt="M2P Fintech" title="" width="100%" height="529">Cybercrime is quickly evolving into an escalating issue across the physical and virtual universe. More than 80% of online businesses have reported an increase in cyberattacks since 2020.The digitization of finance has further widened avenues for hackers to create loopholes in financial infrastructure with sophisticated tools and techniques. Wherever there is a software application or a network involved, cybercriminals infiltrate the system to steal sensitive personal information and financial credentials. Vulnerable financial applications don’t stand a chance before the mushrooming attacks and give way to compromised data, loss of money, identity theft, and data breaches.<h2 class="heading-node" id="d923" style="text-align: justify">Nipping vulnerabilities in the bud</h2>As responsible facilitators of digital banking, payments, and lending services, fintech companies take cybersecurity very seriously. According to the Sixth Annual Bank Survey, more than 70% of fintechs vow to treat information security as their top concern in 2022. They adopt technologies, tools, and even philosophies that will help them nip vulnerabilities right in the bud.<h2 class="heading-node" id="d555" style="text-align: justify">Transition to DevSecOps</h2>Standing at the forefront of technological innovation, fintechs need to deliver secure deployments, application releases, and updates at supersonic speed. But as with every new-age technology, fintech <a class="link" href="https://m2pfintech.com/blog/the-world-of-apis-how-they-power-fintech/">APIs</a> are prone to security risks. These risks reduce go-to-market speed, delay update releases and impair code quality.Even though standard practices such as DevOps delivers tremendous deployment velocity with zero downtime, cloud readiness, robust security, and compliance management, it still fails to address security risks at the grass-root level. That’s why financial software developers mandate the need to integrate security into the DevOps process. They began transitioning towards the DevSecOps to build secure and efficient applications at top speed.DevSecOps quickly evolved as the future of financial software development, as it made cybersecurity a fundamental part of the production pipeline, which comprises architecture design, coding, and testing phases. Today, it is a crucial application development methodology for successfully developing fintech applications in regulated and unregulated domains.<h2 class="heading-node" id="dbbb" style="text-align: justify">What is DevSecOps?</h2>DevSecOps, a blend of development, security, and operations, refers to the adoption of security right at the beginning of the software development lifecycle (SDLC). It is more a philosophy than a tech approach that calls for increased collaboration between development, security, and operation teams.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/05/DevSecOps-blog-banner-02.webp" alt="M2P Fintech" title="" id="hasokqmme" width="100%" height="529">It resonates deeply with the view of Cloud Security Alliance (CSA) which goes, “Security can be achieved only when it has been designed in. Applying security measures as an afterthought is a recipe for disaster.”This is exactly what DevSecOps solves for.<h2 class="heading-node" id="1b91" style="text-align: justify">Why DevSecOps?</h2>During the days of DevOps, security was included late in the lifecycle only after the development and operation phase. Technological advancements in cloud platforms, microservices, and containers could not move forward, as security turned out to be a major bottleneck. Catching security issues late in the cycle resulted in a lot of rework and late releases. These were some of the reasons why fintech application developers shifted to agile DevSecOps practices for quick and modern application development and deployment.By shifting security left, DevSecOps integrates testing checks between the development and operation functions of every sprint. It integrates security into DevOps by tackling issues within Continuous Integration (CI) and Continuous Delivery (CD) pipelines. In doing so, DevSecOps accelerates software delivery, reduces the duration between code change, production, deployment, and release while reducing security risks.<h2 class="heading-node" id="dbb0" style="text-align: justify">Resolving contentions</h2>The fundamental area of contention between development, security, and operation teams is their change implementation, security monitoring, and stability principles. They become a source of friction that often leads to lags in the software development cycle. DevSecOps serves as an effective tool to resolve this friction by providing a culture that empowers the teams to work in sync.<h2 class="heading-node" id="79ef" style="text-align: justify">Functions of DevSecOps</h2>DevSecOps aims at designing novel solutions that simplify complex processes within the agile framework. It ensures that customers suffer no technical glitches after deployment or release of any update, or application.Encompassing threat modeling and security testing processes in the pipelines saves time, effort, and cost. The automation in security testing helps test for vulnerabilities keeping futuristic risk possibilities in mind. Security reports can be easily generated to identify risk patterns in CI and CD. The continuous feedback process at every phase of development and code integration strengthens rectification and delivery infrastructure.<h2 class="heading-node" id="63bb" style="text-align: justify">4 simple steps to develop a DevSecOps culture</h2>For sustained focus on security and application effectiveness, companies need to build a DevSecOps culture. Developing a ‘Security as Code’ philosophy is a vital step towards creating this culture. It calls for consistent, compliant, and collaborative efforts between development, operations, and security teams.Follow the steps below to make DevSecOps culture a breeze.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/05/DevSecOps-blog-banner-03-03.webp" alt="M2P Fintech" title="" id="wnvu7jjqw" width="100%" height="529"><ul class="list-node" id="l13bfyfvi"><li>Garner cooperation&nbsp;— Team silos and conflicts are key reasons why DevSecOps tends to fail in most companies. Garner cooperation through knowledge sharing and reward mechanisms that promote continuous improvement.</li><li>Grant authority and autonomy&nbsp;— Nobody likes dictatorships. Authorize your teams to identify and resolve issues on their own. This autonomy will boost their solidarity and collaboration.</li><li>Appoint strong leaders&nbsp;— Groom or bring in leaders who prioritize security. Make security a top-down mandate. This is a crucial step to building a DevSecOps culture.</li><li>Educate and align&nbsp;— Educate team members on the importance of security, and align the learnings towards DevSecOps tasks. Focus on risk training while also briefing security teams about DevOps methodology.</li></ul>The fundamental goal of the exercise is to make cybersecurity an organization-wide priority, with DevSecOps as a crucial tool.<h3 class="heading-node" id="0f3f" style="text-align: justify">Crucial imperative for fintech application development</h3>A common myth is that developing applications with security in mind impedes innovation. But the security left DevSecOps methodology steers innovation in the right direction and saves a lot of time, effort, and cost.If you are in the business of developing fintech applications, then it’s imperative&nbsp;that you deploy DevSecOps tools and processes as an organization-wide philosophy. As forerunners in implementing the DevSecOps philosophy, we deliver pre-built workflows and AI-powered automation capabilities to deliver secured risk-based authentication at every step. We redefine the software development lifecycle process to accelerate software deployment, product quality, and controlled release cycles and processes.Want to know more about how your business can benefit from the DevSecOps process?Ping us at&nbsp;business@m2pfintech.com.<a class="link" href="https://m2pfintech.com/newsletter/">Subscribe</a>&nbsp;to our newsletter and get the latest fintech news, views, and insights, directly to your inbox.Follow us on&nbsp;<a class="link" href="https://www.linkedin.com/company/m2pfintech/mycompany/">LinkedIn</a>&nbsp;and&nbsp;<a class="link" href="https://twitter.com/m2pfintech">Twitter</a>&nbsp;for insightful fintech tales curated for curious minds like you.
