In 2016, a major US transportation company experienced a significant data breach that exposed the personal information of 57 million users and 600,000 drivers. The breach occurred due to vulnerabilities in the company’s mobile app security. Hackers gained access to sensitive data, including names, email addresses, and phone numbers, as well as the company’s GitHub account, where they found credentials for its Amazon Web Services (AWS). Instead of reporting the breach, the company made the controversial decision to pay the hackers $100,000 in exchange for keeping the incident confidential. This decision resulted in a $148 million fine in 2018 for violating state data breach notification laws – a record fine at the time. The company involved in this incident was Uber.
This data breach case serves as a critical reminder of the importance of mobile app security. A robust security system not only protects user data but also enhances the user experience and builds greater trust in the product. For businesses of all sizes, from startups to large corporations, maintaining mobile app security is essential. In this post, I will discuss why mobile app security is a necessity for businesses, share the best strategies for securing app data, and provide insights on how to approach secure mobile app development.
What is Mobile Application Security?
Mobile application security refers to a comprehensive set of measures designed to protect mobile apps from threats and vulnerabilities. These measures aim to prevent data leakage, unauthorized access, and damage to mobile software applications. Mobile app security integrates various approaches and user experience (UX) techniques throughout the app design process to block unauthorized access or manipulation.
A practical example of securing a mobile application is implementing inactivity timeouts. This feature automatically logs a user out after a period of inactivity (typically 10 to 15 minutes), reducing the risk of unauthorized transactions or data theft if the device is left unattended. Another example is using a security overlay that immediately covers the screen to prevent potential screenshot captures, which could expose sensitive information.
At Pixel Genesys, we understand the importance of mobile app security and excel in developing secure mobile applications. Our team is committed to adhering to security regulations and ensuring that your app is protected from vulnerabilities. We have successfully worked with numerous clients, including Dollar Shave Club, Sprent, and Aspiration, to develop high-quality and secure mobile apps.

12 Strategies for Developing Secure Mobile Apps
Security is a critical aspect of mobile app development, particularly in today’s fast-evolving digital landscape where cyber threats are becoming more sophisticated. Implementing security measures early in the development process, ideally during the design and planning stages, is essential for building a secure app. Once security solutions, such as multi-factor authentication (MFA), are added to an existing app, they can be challenging to integrate, especially when dealing with large, long-term projects. These apps, like those designed to last for over a decade, require careful consideration of security as a core component from the outset. After implementing initial security measures, it’s crucial to regularly assess and respond to emerging vulnerabilities.
Here are 12 strategies for ensuring that your mobile apps, developed with Pixel Genesys, are secure:
1. Analyze Your Data
The first step in securing your mobile app is to analyze the entire data lifecycle, which should be done during the planning or design stage. The goal is to understand how data flows within the app and identify potential vulnerabilities at each stage. Ideally, this analysis can be carried out internally, but you may also hire external consulting firms that specialize in data audits.
A useful approach during this phase is to visualize the entire data lifecycle. Imagine yourself as the data point and track it from the moment a user enters their information to when it is transported to its final storage location. Since most mobile apps serve as clients that fetch data from servers, this analysis helps to identify risks and gaps in the data handling process.
2. Encrypt Your Source Code
According to a report from IT Pro Portal, 82% of vulnerabilities are found in the application’s source code. To mitigate this, Pixel Genesys recommends encrypting and encoding the source code during development. Implement code scrambling (obfuscation), which makes the code harder to understand and reverse engineer. Additionally, runtime protection can be used to prevent attackers from tampering with the code while it is executing.
An industry-standard practice is signing your source code during development. A digital signature verifies the authenticity of the code, ensuring it hasn’t been altered or tampered with after it was signed. This adds an extra layer of security and trustworthiness to the app.
3. Ensure Secure Communication Channels
Data interception is a major concern for mobile apps. To prevent this, ensure that all communication channels are secure. Using encrypted connections such as HTTPS should be the standard for transmitting data. Protocols like SSL (Secure Sockets Layer) and TLS (Transport Layer Security) should be implemented to safeguard data during transmission.
SSL/TLS ensures that communication between your app and the server is secure and that the server you are communicating with is legitimate. This is especially crucial in public settings with open Wi-Fi networks, where man-in-the-middle attacks are common.
4. Include Secure Authentication Methods
Robust user authentication is essential for protecting your app from unauthorized access. Pixel Genesys recommends implementing a combination of traditional username and password login with secondary verification methods like one-time passwords (OTPs) or biometric authentication (fingerprint or facial recognition).
Multi-factor authentication (MFA) should be incorporated as a standard practice, requiring users to verify their identity using two or more independent credentials. Encouraging regular password updates within your app, coupled with internal reminders, helps minimize the risks of phishing attacks. However, MFA is most effective when combined with a strong password management policy, ensuring that passwords remain secure.
5. Implement Data Encryption
Data encryption is one of the most effective methods to protect sensitive information from unauthorized access. This process involves encoding data so that only authorized parties can decrypt and access it.
There are two primary types of encryption:
- Symmetric encryption: This method uses the same key to encrypt and decrypt the data, and is often used for local storage on devices where only a single party (the device) is involved.
- Asymmetric encryption: This method uses a public key for encryption and a private key for decryption, ensuring secure communication between the client (user) and the server.
There are also different levels of encryption:
- File-level encryption: Encrypts individual files stored on a device.
- Database encryption: Encrypts sensitive data stored in a database, typically on the server.
Beyond encryption, certain industries, such as healthcare, use depersonalization (or anonymization) to protect sensitive information, ensuring that identifiable personal data is stored in separate locations to avoid security breaches.
6. Use Only Authorized API Dependencies and Perform API Reviews
When developing mobile apps, it’s essential to choose well-regarded, secure API dependencies and regularly review these APIs for compliance with security standards. For instance, when integrating financial APIs like Plaid or Stripe, it’s crucial to ensure they are secure and don’t expose sensitive data.
Be cautious with external libraries and packages your app uses, even if they serve relatively simple functions. Always verify that the external libraries do not transmit or store user data in insecure ways.
7. Choose Secure and Reliable Data Storage
When selecting a data storage provider, security should be a top priority. Opt for cloud storage services that are widely recognized and adhere to industry security standards. For instance, Pixel Genesys recommends using Amazon’s S3 storage solution, which provides high levels of security and encryption.
For highly sensitive data, such as in military or government applications, it may be necessary to set up localized databases that ensure data remains within national borders, following more stringent security protocols.
8. Conduct Penetration Testing
Penetration testing, also known as ethical hacking, involves hiring cybersecurity experts to simulate real-world attacks and identify weaknesses in your app. These ethical hackers use various methods, such as phishing or direct system attacks, to test the app’s defenses.
Pen tests come in several forms:
- Open-box test: The hacker has some background knowledge of the app’s system.
- Closed-box test: The hacker knows very little, simulating an attack by an external party.
- Covert test: The test is kept secret from most of the organization to evaluate real-time responses.
- External pen test: The focus is on publicly available systems like websites.
- Internal pen test: The tester uses internal network access to evaluate potential insider threats.
Penetration testing is essential for identifying and addressing vulnerabilities before attackers do.
9. Store the Bare Minimum of Sensitive Data
To reduce the risk of data breaches, it’s crucial to only collect and store the data necessary for providing app services. Limit sensitive data storage on users’ devices and store most of the data on secure servers.
By implementing strict data retention policies, you can minimize the exposure of sensitive data in case of a breach.
10. Utilize the Least Privilege Principle
The principle of least privilege dictates that your app should request only the permissions necessary for its operation. This reduces the likelihood of unauthorized access or misuse of system resources.
Regularly review the privileges granted to various parts of your app and ensure that permissions are removed when no longer needed. This helps to keep user data secure by reducing access to the minimum required.
11. Follow Compliance and Integrity Policies
Compliance with data protection laws and regulations is crucial, particularly for apps in sectors such as finance, healthcare, and government. These industries are subject to strict rules regarding data use and privacy. Make sure all third-party services used in your app adhere to these regulations and handle data securely.
Some key regulations include:
- HIPAA (Health Insurance Portability and Accountability Act): A US federal law that mandates national standards for the protection of sensitive patient health information.
Adhering to compliance policies ensures that your app protects user data in accordance with legal requirements.
12. Continuously Test and Update Security
Security isn’t a one-time task; it requires ongoing vigilance. New security threats are constantly emerging, so it’s vital to update your app with the latest security patches and improvements.
Integrate security testing into your Pixel Genesys development process, using Continuous Integration/Continuous Deployment (CI/CD) pipelines to automate security checks. This ensures that security remains a priority throughout the app’s lifecycle, allowing you to address vulnerabilities swiftly and keep your app secure from emerging threats.
By applying these strategies, Pixel Genesys can help you build secure mobile applications that protect user data, maintain privacy, and safeguard against ever-evolving cyber threats.
