Vulnerability discussion

Remote logging to a central log host provides a secure, centralized store for ESXi logs. By gathering host log files onto a central host it can more easily monitor all hosts with a single tool. It can also do aggregate analysis and searching to look for such things as coordinated attacks on multiple hosts. Logging to a secure, centralized log server also helps prevent log tampering and also provides a long-term audit record.

Check content

From the vSphere Client select the ESXi Host and go to Configuration >> Advanced Settings. Select the Syslog.global.logHost value and verify it is set to a site specific syslog server hostname. or From a PowerCLI command prompt while connected to the ESXi host run the following command: Get-VMHost | Get-AdvancedSetting -Name Syslog.global.logHost If the Syslog.global.logHost setting is not set to a site specific syslog server, this is a finding.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
