Which of the following is NOT a function of security services?

• A. Counter security attacks
• B. Facilitate unauthorized access
• C. Enhance data processing security
• D. Utilize security mechanisms

Answer: (B)

The option that states "Facilitate unauthorized access" accurately identifies an action that is contrary to the primary goals of security services. Security services are designed to protect information and systems from unauthorized access, ensuring confidentiality, integrity, and availability of data.

The first option, which mentions "Counter security attacks," reflects a core function of security services aimed at identifying, preventing, and responding to threats and vulnerabilities in systems. Enhancing data processing security is also a central function, as it involves implementing measures to protect data while it is being processed. Utilizing security mechanisms relates closely to employing various technologies and strategies to bolster an organization’s security posture.

In summary, facilitating unauthorized access runs counter to the fundamental objectives of security services, making it the correct choice for an action that is NOT a function of these services.
