Description
vCenter must be configured to send near real-time log data to syslog collectors so information will be available to investigators in the case of a security incident or to assist in troubleshooting.

ℹ️ Check
Open the Virtual Appliance Management Interface (VAMI) by navigating to https://<vCenter server>:5480. Log in with local operating system administrative credentials or with a Single Sign-On (SSO) account that is a member of the "SystemConfiguration.BashShellAdministrator" group. Select "Syslog" on the left navigation pane. On the resulting pane on the right, verify at least one site-specific syslog receiver is configured and is listed as "Reachable". If no valid syslog collector is configured or if the collector is not listed as "Reachable", this is a finding.

Edit or add the address and port of a site-specific syslog aggregator or Security Information Event Management (SIEM) system with the appropriate protocol. User Datagram Protocol (UDP) is discouraged due to its stateless and unencrypted nature. Transport Layer Security (TLS) is preferred. Click "Save".
