(ISC)2 Certified in Cybersecurity Practice Exam

What is a security clearance?

1. A level of authorization allowing access to sensitive information

2. A type of encryption used in security protocols

3. A policy for managing network risks

4. A requirement for conducting security audits

The correct answer is: A level of authorization allowing access to sensitive information

A security clearance refers to a specific level of authorization granted to individuals, allowing them access to sensitive or classified information. It is a formal determination that an individual meets the necessary standards of trustworthiness and reliability to handle information that could be detrimental to national security or an organization's interests if disclosed improperly. The process for obtaining a clearance typically involves thorough background checks, which can include assessments of an individual’s criminal history, financial stability, and personal conduct. This strict vetting process ensures that only those who can be trusted with sensitive information receive access, thereby maintaining the integrity and confidentiality of critical data. In contrast, the other options describe various components in the realm of cybersecurity but do not pertain to the concept of security clearance. Encryption refers to methods used to protect data both in transit and at rest. Policies for managing network risks focus on identifying and mitigating vulnerabilities within a network infrastructure. Requirements for conducting security audits relate to the standards and procedures followed to evaluate the security posture of an organization or system. These roles and concepts are distinct from the notion of authorization and access rights associated with security clearances.
