Host must configure the password history setting to restrict the reuse of passwords

中レベル 1自動vmware

説明

The goal is to inhibit the reuse of past passwords, acting as a deterrent against potential security breaches stemming from the exploitation of old, compromised credentials. This is achieved by configuring the Security.PasswordHistory parameter, which specifies the number of unique passwords a user must cycle through before a previous password can be reused. The audit reads Security.PasswordHistory with esxcli and requires 5. Runs in the ESXi Shell (busybox sh) as root.

case "$v" in ''|*[!0-9-]*) echo '/Security/PasswordHistory: no integer value'; exit 1 ;; esac
if [ "$v" -eq 5 ]; then echo compliant; else echo "/Security/PasswordHistory = $v (expected 5)"; fi
