Security Testing is the process of evaluating a system, application, or network to identify vulnerabilities and ensure it is protected against potential threats. It involves assessing various aspects such as data encryption, authentication, authorization, and access control mechanisms to prevent unauthorized access, data breaches, and cyberattacks. Common security testing methods include penetration testing, vulnerability scanning, and risk assessment. The goal is to ensure the system's confidentiality, integrity, and availability are maintained, while also identifying any weaknesses before they can be exploited by malicious actors. Effective security testing helps organizations safeguard sensitive information and maintain user trust.
