Auditing Your iOS Mobile App: A Comprehensive Guide to Detecting Attacks and Protecting Sensitive Data

Discover AppScan offers

Auditing an iOS application is an important step in the app development process. It is necessary to ensure its functionality, protect sensitive data, and detect any potential attacks. This blog will provide comprehensive guidance on how to audit an iOS mobile application, from source code review to using a website auditor and web browser. Additionally, advice on how to prevent data leakage will be discussed in order to help developers, businesses, and clients safely audit their iOS applications.

What is an audit of an iOS app?

An audit of an iOS mobile application is process of examining and analyzing its security, functionality, and performance. During the audit process, testers look for potential threats and vulnerabilities in the code, user experience, data privacy and more. Auditing is essential for developers and businesses to ensure their apps perform optimally. Well managed audits also help to protect sensitive data stored on the device from potential attackers or malicious software.

Types of audits for mobile applications

The type of audit conducted will depend on the needs of the project. For example, if an app collects sensitive data from users, such as financial information or medical records, then a thorough security audit should be conducted that looks for potential vulnerabilities in the code as well as vulnerabilities that could arise from user activities.

On the other hand, if an app does not handle sensitive data, then an audit might assess performance metrics mostly related to speed and user experience. Auditing should also include testing across multiple devices and operating systems including Android, Apple's iOS, Windows Phone and Web apps.

How to Audit the Source Code?

Auditing an apps source code is essential to prevent any potential attacks. Auditing the source code requires specialized tools and techniques. Here are some of the most common methods used in source code analysis.

Tools and techniques used in source code analysis

  • Syntax Analysis: This technique checks for syntax errors in the code. For example, if there is a missing semicolon or an incorrect character in a line of code, this can cause the application to crash when it is executed by the device.
  • Logic Analysis: This involves checking the logical consistency of the code, such as identifying infinite loops or ensuring that all conditions are met. This helps to identify any potential problems with the code before it is deployed.
  • Vulnerability Analysis: This technique looks for potential security vulnerabilities in the code, such as SQL injection attacks or cross-site scripting (XSS) attacks. If left unchecked, these types of vulnerabilities can be exploited by attackers to gain access to sensitive user data.

How to Use Website Auditor and Web Browser Checker?

Using website auditor tools can be advantageous when testing mobile apps on iOS devices. These tools allow developers to automate the testing process and check for any issues with the software in a quick and efficient way. Here are some of the benefits of using website auditor tools:

  • Checks for compatibility issues: Web browser compatibility is an important factor when it comes to accessing websites from different browsers. A website auditor tool can quickly identify any issues that may arise from incompatibility.
  • Tests performance: A website auditor tool can also be used to test an app’s performance by checking for response times, loading times and other factors that could have an impact on user experience.
  • Runs automated tests: Website auditor tools allow developers to automate parts of the testing process with automated tests, which can save time and money.

Preventing Data Leakage: Best Practices & Tips for Developers & Businesses

Data leakage prevention is a key factor when auditing an app for security. Data stored on the device should be properly encrypted, both in transit and at rest, to ensure that it can't be accessed by unauthorized parties. Here are some tips and best practices for preventing data leakage:

  • Encrypting data: Data stored on the device should be encrypted using strong encryption algorithms such as AES-256. This helps to protect user data from potential attackers or malicious software.
  • Implementing authentication measures: Implementing authentication measures such as two-factor authentication can help to deter hackers from accessing sensitive user data.
  • Using secure network protocols: Secure network protocols such as HTTPS/SSL encryption should always be used when transmitting data between the client and server.
  • Monitoring application usage: Application usage activity should be monitored on a regular basis, so that any potential security breaches can be identified quickly and addressed appropriately.
  • Updating software regularly: Software should be regularly updated with the latest security patches to help prevent any potential vulnerabilities.
  • Restricting access control lists: Access control lists (ACLs) should be set up based on user roles to ensure that only those with the necessary permissions can access data stored on the device.
  • Educating users about cyber threats: It is important to educate users about potential cyber threats and best practices when it comes to handling their data, such as not entering sensitive information into untrusted websites.


By using the tips outlined in this article, developers, businesses, and clients can easily audit the security and performance of their iOS applications in a secure and efficient way. Audits help to protect sensitive data from potential attackers or malicious software, and ensure that the applications perform optimally for users. As mobile application usage continues to grow, auditing will become increasingly important for developers and businesses.

Benefits of auditing an iOS app for security and performance:
Auditing an iOS application can help to protect sensitive data from potential attackers or malicious software, and ensure that the application performs optimally for users. It is a necessary step for developers and businesses, as it helps to identify any potential issues with the code or user experience before the app is released. By auditing an application regularly, developers and businesses can ensure their application is secure and performs well over time.
