8 Security Measures Essential to Robust Android App


Mobile applications now predominantly facilitate online tasks like paying utility bills, scheduling appointments, and buying movie tickets. These digital tools act as virtual gateways, linking servers and APIs globally to offer users a spectrum of services, data, convenience, and value.

While mobile apps showcase remarkable utility and potency, they conceal various risks and issues that threaten their security and databases. The storage of sensitive data within mobile apps also makes them attractive targets for malicious activities. Shockingly, a report highlights that over 56% of top paid iOS apps and the leading 100 paid Android apps on the Google Play Store have experienced hacking incidents.

Hence, it is paramount to prioritize the security of your mobile app and shield user information from potential breaches that could not only impact your clients but also significantly harm your company. If you are involved in mobile app development and require cybersecurity counsel, you have landed at the ideal destination.

Secure Your Network Connections

Adequate security measures should be in place on the mobile app’s servers to protect data and prevent unauthorized access. Furthermore, API access should be restricted to authorized personnel within your organization. 

Containerization is a method for creating secure storage containers for documents and data. This process involves bundling an application with its libraries, dependencies, and configuration files to ensure smooth operation across different computer platforms.

Engaging a penetration tester is recommended to assess your app’s security. Qualified professionals in this field can identify and address any vulnerabilities present. Enhancing database security through encryption using Secure Sockets Layer, Transport Layer Security, and Virtual Private Network protocols is advisable.

To enhance mobile app security further, developers can implement federation, which involves distributing resources across multiple servers and safeguarding critical assets from unauthorized users.

Mask Your Code

Obfuscation is a strategy for confusing hackers by creating complex machine or source code that is hard to decipher. This can be achieved by manually eliminating unnecessary metadata and debugging data. Consequently, the attacker is left with limited information, enhancing mobile app security.

In manual obfuscation, one may choose to encrypt parts or the entirety of the code. Another approach involves appending irrelevant labels to variable and class names as prefixes. Some developers integrate dummy code into the program while maintaining its underlying logic. Embedding anti-tamper protection within the source code presents an alternative tactic.

Any modifications to the code trigger random crashes or sudden halts. Developers or relevant authorities in the mobile app development field should be notified of instances of tampering as a preventive measure.

Protect Transit Data

Ensuring the protection of your transit data is crucial. Preemptive measures to safeguard your transit data are crucial. Implementing advanced jailbreak detection and access control based on status is essential.

The organization must restrict access to corporate data from devices flagged as non-compliant. Erase all business-related information from a lost or stolen device. Measures are in place to secure the data and prevent unauthorized access.

Selective deletion of company data from devices is feasible. The IT department or users can initiate this process. You can also decide to outsource application modernization services to improve IT processes, reduce operational costs, and improve security.

Consistent Testing and Maintenance

Most Android devices are operating on antiquated versions of the Android system. Data reveals that a considerable portion of Android devices exceed a 2-year lifespan, putting 75% of them in vulnerable positions. Understand that hackers actively exploit software vulnerabilities.

Hackers uncover additional weaknesses when one security loophole is patched by developers. Despite Google’s efforts, the continuous evolution of threats poses a challenge. Regular updates to the Android OS are implemented to counter these risks effectively. Penetration testing is a secondary measure to assess server-side security and uphold a strong defense mechanism.

Enforce Appropriate Session Handling

Ensure the session management process is executed correctly to safeguard against unauthorized attempts to compromise sessions through hijacking or account attacks. Implement session timeouts, token-based authentication, and secure session storage techniques to mitigate the risk of unauthorized access to personal information or sensitive data from infected accounts or systems. Additionally, limit session durations to a reasonable period of inactivity unless the user explicitly logs out or their account is removed.

Utilize Only APIs that Are Authorized

Unauthorized APIs may inadvertently provide hackers with access, potentially resulting in severe consequences. Programmers find it more convenient to reuse cached authorization data when initiating API calls. Furthermore, the accessibility of APIs simplifies the coding process.

However, this convenience also creates opportunities for attackers to exploit privileged accounts. The most effective strategy to bolster API security involves centralizing their authorization.

Add Tamper Detection to Your App

When modifying your code, proceed with caution. Maintaining a log of code changes within your mobile application is essential to prevent malicious developers from injecting harmful code. Implement triggers within your application to track activities effectively.

Utilize a developer certificate for your mobile app to enhance security measures. For every app installation, ensure it undergoes certificate verification before becoming operational. Begin by acquiring a developer certificate signature, integrating it with a string element, and validating the signature during runtime. If unauthorized alterations to your code occur, the app will detect an invalid code and block its execution.

Compliance and Integrity

When a mobile app is released, it must meet specific security criteria and adhere to guidelines. Developers may need to follow particular security measures as directed by the app store, especially concerning the download and installation processes.

Modern smartphones rely on app stores to distribute verified apps requiring code signing, ensuring that only approved applications are available. Developers submit their apps to the store to validate their identities and security requirements. The app can be downloaded if everything aligns with the operating system’s standards.

Despite the initial complexity, various code signing options simplify this process. Acquiring an affordable code signing certificate swiftly ensures compliance and veracity, confirming the code’s integrity and source. 

This certificate allows developers to encrypt their identity information, which users can decrypt using a provided public key. Understanding APIs (Application Programming Interfaces) is also crucial for bolstering app security.

Last Words

By implementing these eight key strategies, developers and users can shield personal data and devices from cyber risks. Developers must prioritize secure coding, maintain regular updates, and conduct vulnerability assessments. Users should activate security features, exercise caution with permissions, and ensure app updates are current. These actions fortify defenses against potential cyber attacks, guaranteeing a more secure mobile environment.
