<p>In a virtualization environment (100), a host machine (210) on which a guest machine (205) is operable is monitored to determine that it is healthy by being compliant with applicable policies (such as being up to date with the current security patches, running an anti-virus program, certified to run a guest machine, etc.) and free from malicious software or "malware" (252) that could potentially disrupt or compromise the security of the guest machine (205). If the host machine (210) is found to be non-compliant, then the guest machine (205) is prevented from either booting up on the host machine (210) or connecting to a network (223) to ensure that the entire virtualization environment (100) is compliant and that the guest machine (205), including its data and applications, etc., is protected against attacks that may be launched against it via malicious code that runs on the unhealthy host machine (210), or isolated from the network (223) until the non-compliancy is remediated.</p> |
