Verify TOSS 5 does not have unauthorized IP tunnels configured.
Determine if the "IPsec" service is active using the following command:
$ systemctl status ipsec
ipsec.service - Internet Key Exchange (IKE) Protocol Daemon for IPsec
Loaded: loaded (/usr/lib/systemd/system/ipsec.service; disabled)
Active: inactive (dead)
If the "IPsec" service is active, check for configured IPsec connections ("conn"), using the following command:
$ grep -rni conn /etc/ipsec.conf /etc/ipsec.d/
Verify any returned results are documented with the ISSO.
If the IPsec tunnels are active and not approved, this is a finding.
Fix Text (F-87146r1201019_fix)
Remove all unapproved tunnels from the system or document them with the ISSO.
