Host must automatically terminate idle host client sessions

SrednjaNivo 1Automatskavmware

Opis

Configuring the host to automatically terminate idle host client sessions helps mitigate security risks associated with unattended sessions, which could potentially be exploited. The recommended setting for this control is a timeout value of 900. The parameter governing this behavior is UserVars.HostClientSessionTimeout. The audit reads UserVars.HostClientSessionTimeout with esxcli and requires 900 seconds or less (0 = unlimited fails). Runs in the ESXi Shell (busybox sh) as root.

Kako se proverava

Metod provere: Komanda ljuske

shell

out=$(esxcli system settings advanced list -o /UserVars/HostClientSessionTimeout 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/UserVars/HostClientSessionTimeout: no integer value'; exit 1 ;; esac
if [ "$v" -gt 0 ] && [ "$v" -le 900 ]; then echo compliant; else echo "/UserVars/HostClientSessionTimeout = $v (expected 1-900)"; fi

Očekivani izlaz: compliant

Kako se ispravlja
