Protect the host where vCenter Server is running against vulnerabilities and attacks by ensuring that the operating system of the host (Windows or Linux) is as secure as possible.

Maintain a supported operating system, database, and hardware for the vCenter Server system. If vCenter Server is not running on a support operating system, it might not run properly, making vCenter Server vulnerable to attacks.

Keep the vCenter Server system properly patched. By staying up-to-date with operating system patches, the server is less vulnerable to attack.

Provide operating system protection on the vCenter Server host. Protection includes antivirus and antimalware software.

For operating system and database compatibility information, see the vSphere Compatibility Matrixes.
