True. A security assessment is a process of evaluating the effectiveness of security controls implemented on information systems. The assessment can identify weaknesses, vulnerabilities and potential threats that could be exploited by an attacker to gain unauthorized access to sensitive information. Security assessments can be performed using a variety of methods, such as vulnerability scanning, penetration testing, and risk analysis. These assessments help organizations to identify and prioritize security risks and to implement appropriate countermeasures to mitigate those risks.
