Question 20

HIPS implements Preventive and Detective security controls.

Deploying Host Intrusion Prevention Systems (HIPS) serves as both a preventive and a detective security control. It aims to thwart potential intrusions while also monitoring and identifying any suspicious activities on the host system.

A) Directive

Directive controls are those that outline policies and procedures for employees to follow. HIPS does not primarily provide guidance or instruction; rather, it actively works to prevent and detect intrusions, making this option incorrect.

B) Preventive

HIPS acts as a preventive control by blocking unauthorized access and potential threats before they can exploit vulnerabilities in the system. This proactive approach to security is essential in protecting sensitive data and maintaining system integrity.

C) Physical

Physical controls involve measures taken to protect the physical environment, such as locks and surveillance systems. HIPS does not pertain to physical security measures; it is focused on software and network security, rendering this option incorrect.

D) Corrective

Corrective controls are designed to restore systems after a security incident has occurred. While HIPS can assist in mitigating the impact of an intrusion, its primary function is not corrective but preventive and detective, making this option unsuitable.

E) Compensating

Compensating controls are alternative measures implemented to satisfy security requirements when primary controls are not feasible. HIPS does not serve this purpose directly, as it functions more as a primary control for intrusion prevention and detection, thus making this option incorrect.

F) Detective

HIPS also serves as a detective control by monitoring system activities and alerting administrators to suspicious behavior. This capability to detect and report potential threats enhances the overall security posture of the organization.

Conclusion

HIPS effectively embodies both preventive and detective security controls, making options B and F the correct choices. Other options fail to match the functional characteristics of HIPS, as they either focus on different aspects of security management or do not apply to the context of intrusion prevention and detection.
