Description:    Ubuntu 16.04 LTS
Release:        16.04

$ apt-cache policy strongswan

  Installed: 5.3.5-1ubuntu3

Looks like 'ipsec status' might be causing strongswan's charon to write
to run/systemd/journal/dev-log instead of /run/systemd/journal/dev-log
and apparmor doesn't like it.

Extract from /etc/apparmor.d/abstractions/base :
  /{,var/}run/systemd/journal/dev-log w,

With an established ipsec connection, issue the following :

$ sudo ipsec status
connecting to 'unix:///var/run/charon.ctl' failed: Permission denied
failed to connect to stroke socket 'unix:///var/run/charon.ctl'


$ journalctl
