Security testing is a process used to identify vulnerabilities, threats, and risks in software applications and systems. It ensures that data and resources are protected from potential attacks or unauthorized access. By simulating various types of cyber threats, security testing helps organizations understand their security posture and improve their defenses. There are several methods of security testing, including penetration testing, vulnerability scanning, and risk assessment. Each method focuses on different aspects of security, allowing teams to detect weaknesses and implement necessary fixes. Ultimately, security testing is essential for maintaining the integrity and confidentiality of sensitive information.
