Code audit is a key part of ensuring the safety and quality of software systems. It carries out a systematic in-depth inspection of the source code of the software. During the audit, professional tools and rich experience were used to analyze the code in detail from multiple dimensions. On the one hand, every effort is made to uncover potential security vulnerabilities, such as common high-risk vulnerabilities such as SQL injection and cross-site scripting attacks (XSS), to prevent attackers from illegally hacking the system and stealing sensitive data; on the other hand, strictly compare established coding specifications to find code fragments that violate the specifications, avoid potential risks caused by improper code writing, and screen for quality defects that may affect software stability and performance.

Through comprehensive code-level analysis and detection, security risks and various problems hidden in the target application system are accurately located, security flaws are clearly identified, and a strong line of defense is built at the source, so that attackers can take advantage of it indiscriminately, effectively prevent the application's own vulnerabilities from being exploited maliciously, and protect the stable and safe operation of the application system.
