Mobile Device Security: Data Protection on iOS & Android
Mobile devices are essential to our everyday lives. They allow us to access the internet, communicate with others, and store important documents in the cloud.
But mobile devices also collect data about their users and share that information with third parties. This can lead to privacy and even security issues if you’re not careful when developing your app.
Android and iOS employ various security measures to protect user data. Yet, we spend increasing amounts of time using phones for personal and corporate purposes. It’s become even more crucial to strengthen mobile security measures further.
Mobile Devices, Data & Privacy
Mobile devices constantly collect and share data, making personal privacy an issue.
Mobile devices collect user information and location information, which can be shared with third parties for various purposes, including ad targeting. These third parties may use this data in ways you might not expect or approve of, such as selling it to other companies or using it for their own purposes without your knowledge.
The velocity at which data is changing hands keeps getting faster, and the winds of legislative change provide lessons for all companies on data responsibility.
While some laws require companies to be transparent about collecting and using information on mobile devices (e.g., the GDPR), these laws don’t apply everywhere. They aren’t always applied the same across borders.
As a product owner, ask yourself, “Is this necessary?” to help protect user data.
Mobile devices are constantly collecting and sharing data, which can be used to track your location or share personal information. Data protection, security, and privacy are intertwined into the concept of data well-being.
For your app to function properly, it may need access to sensitive information like the user’s location or contacts list. As such, the user must give explicit consent before any such data is accessed or shared.
As an iOS developer (or any other type), you should always ask yourself: “Is this necessary?” If not—and if alternative methods are available—you should use those instead.
Data is a precious resource—one of the most valuable assets to an organization that must be protected accordingly. With data sharing, less is more. Collecting only what you truly need will help protect your users’ privacy and security from potential hackers who might try stealing sensitive information from them through malware attacks on their mobile phone/tablet devices.
Android & Apple: How They Handle Security Differently
Ensuring the safety of our personal data and privacy is of utmost importance, and that’s where mobile security comes into play. When it comes to this, two of the biggest players in the market are Apple’s iOS and Google’s Android. While iOS is renowned for its closed ecosystem and timely security updates, Android’s strength lies in its open nature. Let’s delve deeper into their respective security mechanisms and compare their attributes.
Which is more secure—iOS or Android?
In general, iOS is considered to be more secure than Android. This is due to several factors, including:
- Apple’s Closed Ecosystem: Apple has much more control over the hardware and software that goes into its devices, which makes it more difficult for hackers to find and exploit vulnerabilities.
- Apple’s Aggressive Security Patching: Apple quickly releases security patches for its devices, which helps keep users safe from known vulnerabilities.
- Android’s Fragmentation: The Android ecosystem is very fragmented, with many different manufacturers and carriers offering their own operating system versions. This makes it more difficult for Google to release security patches for all Android devices and gives hackers more targets to exploit.
However, it is important to note that no operating system is 100% secure. There have been malware and hacking attacks on iOS and Android devices. Ultimately, the security of your device depends on both the operating system and the user’s behavior.
Android and iOS devices employ various security measures to keep data safe.
Both Android and iOS use strong encryption features to protect data. If a device is stolen, the data cannot be accessed without the encryption key. However, there are differences in encryption methods between the two platforms.
Android employs device-specific keys that are unique to each device. This means there is no universal key for all Android devices. Google services like Gmail or Chrome may have separate keys associated with them. Both the device-specific key and the Google key are required to access data.
In contrast, iOS uses a combination of device-specific keys and iCloud keys. Even if someone has a device, they still need the iCloud password to access the data.
While both platforms have strong encryption features, encryption is not foolproof. It is essential to take additional security measures to keep data safe.
Security Features on Android Devices
By utilizing data encryption, data accessibility, and other security features, Android devices effectively safeguard data against unauthorized access:
- Data Encryption: Android’s encryption features have become increasingly sophisticated and robust. All Android devices are encrypted by default, and Android 12 introduces improvements such as enhanced file-based encryption, stronger encryption for sensitive data, and new security features for app developers.
- Data Accessibility: Android devices use a permission system to regulate app data access. Only apps with granted permissions can access specific data. App permissions can be managed in Settings > Apps & notifications > Advanced > App permissions.
- Malware: Google Play Protect scans apps for malware and other security threats and monitors devices for suspicious activity.
- Two-Factor Authentication: Android two-factor authentication (2FA) adds an extra layer of security to Android devices and accounts by requiring a code from users’ phones and their passwords when logging in. Android users can enable Android 2FA in Settings > Security > 2-step verification.
- Find My: Find My Device helps locate lost or stolen devices and allows data erasure, if necessary.
- Dedicated Storage: Trusty is a dedicated secure subsystem on Android devices that securely stores sensitive data like fingerprint and face scan data. This data is encrypted and can only be accessed by authorized apps with the correct credentials.
- Security Updates: Google regularly releases security updates for Android, addressing potential vulnerabilities that attackers may exploit. It is important to install these updates promptly.
Furthermore, Google’s latest Android operating system introduces new default app security features. Since Android 7.0 Nougat (released in 2016) automatically encrypts all Android devices. The data on the device is protected by a strong encryption key accessible only with the device passcode, PIN, or pattern.
Android 12, the latest version, introduces additional security features, including:
- Enhanced Encryption: Android 12 encrypts files with unique keys, making it harder for attackers to access data even with compromised device encryption keys. Stronger encryption algorithms protect sensitive data like biometric authentication and app credentials.

Security Features on iOS Devices
iOS devices use a variety of security features to keep your data safe, including:
- Data Encryption: Using a strong encryption algorithm, iOS devices encrypt all user data by default. This means that if someone were to steal your device or gain unauthorized access to the data, they would not be able to read it without the encryption key. Your device passcode, PIN, or pattern protects the encryption key.
- Data Accessibility: iOS devices use a permission system to control which apps can access data. This means that apps can only access data you have permitted. You can control app permissions using Settings > Privacy & Security > App Permissions.
- Malware: Apple does not have a built-in malware scanner for iOS. Instead, Apple relies on several other security features to protect iOS devices, such as:
- Sandbox: iOS uses a sandbox system to isolate apps from each other and the system. This prevents malicious apps from accessing other apps or system files.
- Code Signing: All apps on the App Store are code-signed by Apple. This means that Apple has verified the developer’s identity, and the app has not been tampered with.
- Automatic Security Updates: iOS devices automatically receive security updates from Apple. This helps to keep iOS devices up to date with the latest security patches.
- Two-Factor Authentication: 2FA is a security feature that adds an extra layer of protection to your account by requiring you to enter a code from your phone and your password when logging in. You can enable 2FA for your Apple ID by going to Settings > Your Name > Password & Security.
- Find My: Find My is a service that can help you to locate your lost or stolen device. It can also help you erase your device’s data if necessary.
- Dedicated Storage: Secure Enclave is a dedicated chip that securely stores sensitive data like fingerprint and face scan data. This encrypted data can only be accessed with the iOS user’s passcode, PIN, or pattern.
- Security Updates: Apple releases security updates for iOS regularly. These updates patch security vulnerabilities that attackers could exploit. It is important to install security updates as soon as they are available.
Furthermore, the latest iOS release, iOS 16, introduces several new security features and enhancements that help to protect users from a wide range of threats. Some of these features are, notably:
- Lockdown Mode: Lockdown Mode is a new mode that provides an extreme level of security for users who face targeted threats to their digital security. When Lockdown Mode is enabled, certain features and functionality are limited to help protect users from targeted attacks. For example, most messaging attachments other than images are blocked, and incoming FaceTime calls from unknown callers are prevented.
- Enhanced Privacy Controls: iOS 16 includes several new privacy controls, such as the ability to choose which apps are allowed to access your location and the ability to see which apps have accessed your clipboard in the past hour.
Regarding apps and mobile devices, it’s clear that security is on everyone’s mind. With great convenience comes great responsibility. It’s important to approach security thoughtfully to navigate the digital landscape.
Taking Security Further
As a developer, you can go beyond what the OS offers by investing in security from the ground up.
Taking the right precautions when developing mobile apps can help ensure user data is safe. The first step is to use a secure coding language and development environment. You can also implement specific security measures such as encryption, 2FA, and biometrics authentication.
Securing Your First App
The first step to ensuring your user data is safe is a secure coding language and development environment. There are many ways that hackers can get access to your app’s code, so it’s important that you use secure coding practices at every step of the process.
If you are launching an app for the first time, the most important security things for you to know and implement are:
- Start with a security-first mindset. Keep security in mind throughout development, from design to implementation to testing.
- Don’t underestimate the importance of security testing. Hire a security professional to test your app before you release it.
- Be responsive to security vulnerabilities. If a security vulnerability is discovered in your app, fix it immediately and release a patch.
By following these tips, you can help to ensure that your first app is secure and that your users have a positive experience.
For enterprise-level data protection, add an extra layer of control.
In addition to the above measures, large enterprise apps may also need to consider the following:
- Implement two-factor authentication for all of your apps. 2FA adds an extra layer of security to your apps by requiring users to enter a code from their phone in addition to their password when logging in.
- Use biometrics to authenticate users. Biometrics, such as fingerprints and face scans, are a secure way to authenticate users.
- Use a threat modeling process to identify and mitigate security risks. Threat modeling is a process that helps you to identify and assess potential security threats to your app. Once you have identified the threats, you can implement mitigation strategies to reduce the risk.
- Implement role-based access control. Role-based access control (RBAC) is a system that controls which users have access to which resources in your app. This helps to prevent unauthorized users from accessing sensitive data or performing unauthorized actions.
- Implement a zero-trust security model. A zero-trust security model assumes no user or device can be trusted by default. This approach can help protect your app from unauthorized access, even if an attacker can compromise a user’s account or device.
In addition to the above measures, large enterprise apps may need to comply with various regulations, such as HIPAA, PCI DSS, and GDPR. These regulations often have specific security requirements that must be met.
It is important to educate your employees about security best practices. Security awareness and training will help reduce the risk of human error, a major cause of security breaches.
Treat security as a competitive advantage.

The goal of building an app is to eventually watch it grow in popularity. No business owner has ever said, “I’ll spend money on an app and hope it stays at the bottom of the download chart!” Scalability is the end game for most apps, but it is more than just building the app and hoping someone downloads it in a crowded app store. Defining scalability—the balancing act between taking an application’s capacity to grow while maintaining its performance—should be top of mind for any organization developing or adapting applications. Dozens of factors complicate scaling. Development teams must consider future-proofing code, responding quickly to scope or requirement changes, and focusing on the people involved: end users, developers, and designers. People-first scaling demands thoughtful strategies on how best resources can efficiently meet customer needs while aiming for superior results. In this blog, our engineers and developers offer insights into the power of people and processes and how they work together to reach scalability goals. What is scalability? Scalability refers to the capability of expanding a system in a focused and strategic manner, allowing it to effectively handle increased traffic and accommodate growing demands. App scalability involves thorough documentation and the accumulation of knowledge right from the outset, ensuring a solid foundation for future growth. When done right, scalability enables you to spend more time solving business vs. technical problems—and saves money in both coding and maintenance. While there may be multiple approaches to achieving scalability, the key lies in carefully selecting one method and remaining consistent throughout the system’s development and evolution. By doing so, organizations can ensure the scalability of their systems and effectively adapt to changing needs and requirements. Considerations for Scalability Clarify Your Goals: Engineering teams need to set crystal-clear goals to achieve scalability. Understand different ways to achieve scalability, including a surge in traffic, orders, sales users, or speed. Map out a timeline and budget for your scaling endeavors, ideally before you begin the project. Build for the Future: Launching a minimum viable product (MVP) is a quick and cost-effective way to get started on a small virtual machine. However, it’s crucial to approach it with a forward-looking perspective. Engineers and developers may need help with the temptation to optimize too soon, so leaving room for future optimization and app growth is vital. Plan for Scope Changes: In a project, it’s not a question of whether the scope changes but when it does. Scaling brings changing requirements in terms of technology and features. It is crucial to acknowledge this from the beginning while building. The key is to ensure extensibility. People-First Scaling Developers and engineers should remember that their creations are not solely meant for fellow developers (although a widely used application will inevitably involve interactions with many developers along the way). It is equally important to consider other stakeholders who will interact with the application, such as designers, stakeholders, and end users. Here are some valuable insights on scaling with a people-first approach. Test Assumptions Don’t rely on untested assumptions about what users want from an app. Users generally desire fast, high-quality, cost-effective solutions, but achieving all three can be challenging. Instead of presuming, ask the right questions. For example, inquire about the importance of loading videos quickly or whether security or speed takes precedence. You can gain valuable insights to guide your decisions by asking these pertinent questions. Delay Decisions Delay decisions as long as possible. Small decisions made over time can compound into something unattainable. This is especially true with end users, particularly in the case of native mobile apps. Users have specific expectations regarding how these apps should operate compared to web apps. While many things may change and evolve, having good, clean code will facilitate these changes. Investing time in writing quality code is always worthwhile. Stay Focused To achieve scalability, developers should decouple components to enable independent functionality, making updates more manageable. When considering mobile scaling, there are three key aspects to focus on: Evaluating how to scale new features effectively. Implementing compartmentalization to enable independent work for future developers joining the project. Developing strategies to ensure updates are tolerable. Respect Your Team You’ll undoubtedly add new team members who bring a fresh perspective to a complex project. However, it’s essential to carefully evaluate recommendations and changes. How one new person does something could lead to developing a bad habit that becomes the norm. To scale an app with your people on top of your mind, it all comes down to respect. You’re all learning from one another, from the developer to the designer to the user who downloads. Focus on building a collaborative environment for everyone to be able to scale together. Establishing a Process To Scale Your App Maintaining and managing a project is crucial for building a solid code base. If you continuously onboard developers to work on an ever-expanding list of features, prioritizing your process becomes paramount. Avoid taking shortcuts and establish a robust foundation for long-term success. Here are a few tips for creating a process that will stick. Defining a Process When working with multiple developers, teams, and leaders, it is crucial to establish transparent processes. Leaders play a vital role in determining the essence of the application, while smaller teams focus on tackling specific feature sets. Frequently, these teams operate in parallel but independently, emphasizing the need for proper staffing and training to ensure consistency and seamless integration. However, avoiding overstaffing is essential, as involving too many individuals can hinder progress. Research suggests that there is a tipping point where additional resources slow down progress in the wrong direction. Documentation Matters To mitigate potential issues, anticipate future questions from your team, establish well-defined tickets, clearly define your workflow and responsibilities, and clarify specific acceptance criteria. Things To Watch Out For Rushed coding can lead to sloppy development and an app vulnerable when scaled. Refactoring or restructuring the code without altering its original functionality may be necessary to address these issues. However, refactoring can pose a significant challenge when it comes to scaling, as it requires keeping the base code of the project intact, even as scope and requirements change. Refactoring can add years of work to the project, especially at the platform level. Secret to Scaling: Value Your People & Process Successful scaling of an application is not solely dependent on technology but equally hinges on the people involved and the processes they follow. People-first scaling, focusing on the suitable composition of teams, well-defined roles, and proper training, is integral to achieving streamlined operations and meeting project goals. Equally important is establishing robust development processes, which guide the production of high-quality code and form the bedrock of a scalable application. Processes ensure an app remains resilient despite changing requirements. Scaling is about balancing the human element with the technical and ensuring that one complements the other.
