What are the main functions and goals of security testing?

Main functions and goals of system security testing:

• Vulnerability detection. Checking the system for weak points through which an attacker could gain unauthorized access.
• Assessment of resistance to attacks. Testing how resistant the system is to various types of attacks (SQL injections, XSS, CSRF, etc.).
• Compliance verification with security requirements. Ensuring that the system meets security standards and policies.
• Data protection and confidentiality. Ensuring the safety of user and corporate data.
• Prevention of financial and reputational losses. Early detection of security issues helps avoid serious consequences.

Security testing may include static code analysis, dynamic testing, penetration tests, and configuration audits.
