Do not copy the lockfile directory (the only subdirectory that ends in ".lck").

Make sure the virtual machine is powered off.

Don't register a virtual machine for DHCP on wireless.

When taking a snapshot of a virtual machine and then branching off, make sure to save the image at the instance before the branch (the trunk) rather than at the branch level to ensure security patches are most up to date. If any guest is more vulnerable than other guests or your host, it could be an entry to compromise the rest of your system.Īccess to the host should be limited (firewalled off). All guests on a host machine should have like risk posture - same level of accessibility, data sensitivity and level of protection. Your system is only as secure as the least secure virtual or host machine.

Maintain Like Risk Postures for All Machines (Virtual and Host).

Anti-virus software needs to be installed separately on the Virtual Machine, even if virus protection is already installed on the Macintosh operating system itself. While MIT does its best to prevent virus attacks, no computer is immune to them. We strongly recommend you treat each virtual machine as though it is a real machine for the purposes of security. In most cases, simply treat your virtual workstation as you would any other machine. Follow the recommended best practices for your guest operating system. Take regular updates to your operating system, preferably via an automatic update system. Virtual machines are vulnerable to most of the same things as physical machines including data loss/corruption, hardware failures, viruses, and hackers. We strongly recommend treating each virtual machine as if it was a physical machine for most activities.
