Security Testing

Security testing is a critical sub-discipline of cybersecurity that involves actively probing and analyzing a system, network, or application to uncover vulnerabilities and security weaknesses. Its primary objective is to identify potential threats, such as unauthorized access, data breaches, or denial-of-service attacks, before they can be exploited by malicious actors. Employing a variety of methodologies, including penetration testing, vulnerability scanning, and code analysis, security testing is an essential practice throughout the software development lifecycle to ensure the confidentiality, integrity, and availability of information systems.
