Which option is an example of a major access-control violation?

• A. Falsifying or altering Airport ID badge
• B. Not wearing a uniform
• C. Carrying personal items into sterile area
• D. Not reporting lost badge

Answer: (A)

Understanding access control means recognizing how credentials are used to verify identity and grant entry to restricted areas. Falsifying or altering an Airport ID badge directly defeats that verification system, allowing someone to pose as an authorized user or access areas they shouldn’t. This breaks the fundamental trust in the credentialing process and can enable unauthorized entry, posing serious safety and security risks. Because the badge itself is the primary mechanism controlling access, tampering with it is a major breach of security.

Not wearing a uniform signals noncompliance and can trigger additional checks, but it does not by itself bypass the access controls. Carrying personal items into a sterile area raises contamination or policy violations, not directly the credential-based access control. Not reporting a lost badge undermines accountability and could enable misuse if someone else finds and uses it, but its impact is less immediate than forging a credential.
