The goal is to identify vulnerabilities, ensure compliance with regulations, and recommend improvements to protect sensitive data. This process often involves reviewing access controls, network configurations, and security protocols. During a security audit, professionals may use various tools and techniques to analyze the effectiveness of existing security measures. The findings help organizations like businesses and government agencies strengthen their defenses against potential threats, ensuring the safety of their information and assets.
