Code audit is to check for security vulnerabilities in the source code, and identify any potential security risks or non-standard coding practices. This is done through automated tools or manual inspection of the source code, analyzing it line by line to identify any code defects that could lead to security vulnerabilities. Code audit provides measures and suggestions for code revision. When auditing software, each critical component should be audited separately and as a whole. It is advisable to first search for high-risk vulnerabilities and then address low-risk ones. The existence of vulnerabilities between high and low risk depends on the specific situation and how the source code is used. Application penetration testing tries to reduce vulnerabilities in the software by attempting to shut down the application by launching as many known attack techniques as possible on possible access points.
This is a common audit method used to identify specific vulnerabilities rather than code vulnerabilities. Some people claim that audit methods that end with a cycle often overwhelm developers and leave the team with a long list of known issues, but they do not actually improve much. In such cases, online audit methods are recommended as an alternative. Source code audit tools typically look for common vulnerabilities and are only suitable for specific programming languages. These automation tools can be used to save time, but should not be relied on for in-depth auditing. It is recommended to use these tools as part of a policy-based approach.
If set to a low threshold, most software audit tools will detect many vulnerabilities, especially when code has not been audited before. However, the actual importance of these alarms also depends on how the application is used. Libraries linked to malicious code (and must be immune to them) have very strict requirements, such as cloning all returned data structures, because attempts to sabotage the system are expected.
