4. Security auditing

Security auditing is a review of security policies and procedures to ensure compliance and effectiveness. It entails evaluating system configurations, access controls, and other security measures to ensure they meet industry standards and regulatory requirements. By conducting reviews of security policies and procedures, organizations can verify the effectiveness of their security measures and ensure compliance with industry standards and regulatory requirements. Security auditing can be carried out at various levels, including system, application, and infrastructure levels, to provide a comprehensive assessment of the system's security posture.


5. Ethical Hacking

Ethical hacking, also referred to as white-hat hacking, is a proactive approach to security testing that involves authorized attempts to exploit vulnerabilities to identify areas for improvement. It is conducted with the permission of the system owner and aims to identify vulnerabilities that could be exploited by malicious actors. By identifying and addressing vulnerabilities, organizations can strengthen their systems against potential cyber threats and protect sensitive data.


6. Web App Security Testing

This form of security testing assesses web applications for vulnerabilities such as SQL injection, cross-site scripting, and other common web application weaknesses. It involves simulating attacks on web applications to identify potential security weaknesses. By identifying and addressing vulnerabilities, organizations can safeguard their web applications from potential cyber threats and ensure the confidentiality, integrity, and availability of their data.
