A guide to mobile app security: defending against the OWASP top 10 risks


Apps and their associated risks are pervasive and influence every aspect of our life. Our phones’ apps, whether they be for social media, games, or commerce, improve convenience and quality of life. However, these amazingly helpful apps also store quite a lot of personal information about us — our passwords, photos and messages. By learning the owasp mobile top 10 risks and its antidotes, developers can improve their applications’ security posture and protect users from potential threats. Therefore, in this guide, we will discuss each of the risks and provide you with some suggestions for safeguarding your product and users:

1: Broken access control

When users are able to access areas of the programme that they shouldn’t be able to, this is known as broken access control. This could mean seeing sensitive information or doing things they shouldn’t be allowed to do. Developers must impose rigorous guidelines on who can access what in order to address this. For example, if you have an app for a bank, regular users shouldn’t be able to see other people’s account details. Only bank employees or administrators should have access to that kind of information. So, you need to make sure the app is set up to only allow the right people to see and do certain things. By establishing roles and permissions, developers can accomplish this.

2: Cryptographic errors

The security of mobile apps is significantly at risk from cryptographic errors. When cryptographic methods are not applied appropriately, vulnerabilities can easily be exploited by attackers to obtain sensitive information. Using strong encryption methods and sound key management procedures is crucial to reducing this danger. While key management makes sure that encryption keys are generated, kept, and transferred safely, encryption methods jumble data so that only authorised people can access it.

3: Injection

One frequent way that attackers take advantage of mobile apps is through injection vulnerabilities. These vulnerabilities arise from the improper validation or sanitization of untrusted data that is passed to an interpreter, like a command shell or database query. Developers should use parameterized queries and stringent input validation to protect against injection attacks. While parameterized queries keep data and commands apart and stop attackers from inserting dangerous code into queries, input validation makes sure that data follows specified formats and ranges.

4: Insecure design

A mobile app’s security can be compromised from the ground up by insecure design mistakes. These shortcomings are the result of bad architectural choices or insufficient attention to security concerns throughout the design process. To address insecure design defects, developers must do extensive security evaluations throughout the design process, identifying possible vulnerabilities and implementing appropriate remedies.

5: Security misconfiguration:

When developers fail to correctly establish security settings in their mobile apps, it can lead to security misconfigurations. These mistakes may result in significant flaws that provide hackers the opportunity to take advantage of holes and obtain unauthorised access to private data. Developers need to carefully check and set up every part of their app’s security settings, such as encryption protocols, access controls, and permissions, to mitigate this risk. Frequent audits and automated scans can enhance the mobile app’s overall security posture by locating and fixing misconfigurations before hostile actors can take advantage of them.

6: Vulnerable and outdated components:

Using redundant or insecure components in your mobile app may expose it to a variety of security concerns. To ensure your app’s security, you must be diligent and aggressive in handling these components. Use trusted security tools to check your app and its dependencies for vulnerabilities on a regular basis. These checks might help detect flaws in the components you’re employing. Once vulnerabilities have been found, consider their possible influence on your app’s security.

7: Identification and authentication failures

What happens when identification and authentication are unsuccessful? Unauthorized access to user accounts and sensitive data puts the confidentiality and integrity of the mobile app in particular danger. Building resilience into the app can help to lessen this risk. Developers must employ robust ways of identifying and authenticating their users: in particular, strong passwords; multi-factor authentication processes including SMS messaging tokens, one-time password or key generation token systems; secure session control procedures etc.

8: Software and data integrity failures

Software and data integrity flaws pose severe dangers to the security of mobile apps. These errors might cause unauthorised modifications to the app’s code or data, potentially exposing it to attackers. To reduce these concerns, developers must include strong integrity checks and digital signatures across their application’s design. By implementing these safeguards, developers may identify and prevent unauthorised changes to their app’s code or data, ensuring that it stays secure and reliable.

9: Security logging and monitoring failures

A complete security approach for mobile applications requires effective logging and monitoring. When recording and monitoring procedures are inadequate, it is difficult to discover and respond to security problems quickly. Developers must provide comprehensive logging methods that capture relevant security events within the programme. By constantly checking these logs for unusual activity, developers may detect possible security breaches early on and take proper measures to mitigate them. Establishing explicit incident response methods improves the app’s ability to handle security problems quickly and efficiently.

10: Server-side request forgery

SSRF is a serious vulnerability for mobile app security. This could enable attackers to change the requests the server made. Further, it could result in unauthorized access to important information and resources. To be protected against SSRF attacks, developers need to filter and cleanse user-entered data. This way, it will not cause harmful or unauthorized requests. Developers should also restrict the server to just trusted sources and domains in how it sends requests. This should prevent abuse of the system. By applying these precautions, developers can greatly reduce the risk of SSRF attacks and shield their mobile programs from unauthorized interference and access.

Wrapping up

Understanding and resolving the OWASP Top 10 threats for mobile app development with the use of excellent app shielding and runtime app security solutions like Appsealing may improve your app’s security posture and safeguard both your users and your reputation. Stay cautious, constantly learning about emerging dangers, and prioritise security throughout the development lifecycle!
