GSEC · Question #247

What is a limitation of deploying HIPS on a workstation?

The correct answer is C. Restricted support for custom applications. Host Intrusion Prevention Systems rely on behavioral rules and signatures that may not account for the unique runtime behavior of custom or in-house developed applications, causing conflicts or missed detections.

Why each option

Host Intrusion Prevention Systems rely on behavioral rules and signatures that may not account for the unique runtime behavior of custom or in-house developed applications, causing conflicts or missed detections.

ARequires more frequent system patching

HIPS does not inherently increase the frequency of system patching requirements; patch management is a separate administrative process independent of HIPS operation.

BRequires an HIDS to Identify an attack

HIPS is capable of both detecting and preventing attacks autonomously without requiring a separate HIDS component, as it combines detection logic with active blocking capabilities.

CRestricted support for custom applicationsCorrect

HIPS monitors application behavior by intercepting system calls and comparing activity against predefined policy rules. Custom applications with non-standard behavior patterns often trigger false positives or require extensive manual rule creation that vendor-provided policies do not cover, making HIPS difficult to deploy effectively in environments with proprietary software.

DRuns as a non-privileged user

HIPS must run with elevated privileges to intercept kernel-level and system calls; running as a non-privileged user would prevent it from functioning correctly.
