A team recently discovered that an environment hosting multiple guests has flaws that could allow infiltration. Which action best reduces exposure to these flaws?
Divide the network into multiple subnets for different guest systems
Prioritize maintenance activities on hosted instances over the main platform
Limit updates to hardware drivers while maintaining the environment’s base configuration stability
Adopt a routine schedule to install updates on the virtualization layer
Applying timely fixes to the underlying virtualization layer is essential. Focusing maintenance on hosted instances alone leaves the foundation unpatched. Segmenting the network may slow an attacker’s movement, but the driver-level or guest-level approaches do not resolve weaknesses across the entire platform. Maintaining stability without updating does not address these vulnerabilities. Regularly installing updates on the virtualization layer addresses its root flaws and mitigates future risks.
