Host SSH daemon, if enabled, must set a timeout count on idle sessions

SrednjaNivo 1Automatskavmware

Opis

Setting a timeout count on idle SSH sessions ensures that inactive sessions are automatically disconnected after a specified period. This period is calculated by multiplying the timeout count with the idle timeout interval. Automatic disconnection of idle sessions reduces the window of opportunity for unauthorized access. The audit reads /etc/ssh/sshd_config and requires ClientAliveCountMax to be set to a non-zero value; confirm it matches the approved value. Runs in the ESXi Shell (busybox sh) as root.

Kako se proverava

Metod provere: Komanda ljuske

shell

f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
v=$(awk 'tolower($1)=="clientalivecountmax" {print $2; exit}' "$f")
case "$v" in ''|*[!0-9]*) echo 'ClientAliveCountMax ${v:-not set}'; exit 1 ;; esac
[ "$v" -gt 0 ] && echo compliant || echo 'ClientAliveCountMax is 0'

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

To remediate this recommendation, set ClientAliveCountMax to the approved value, then restart SSH if enabled and test that inactive sessions are closed after the configured interval/count.
