Ownerships in /var/log/.

[peter@easthope.ca]

All of the files and most of the directories in /var/log/ are owned 
by root.  These are the exceptions.

root@joule:/var/log#   ls -ld {c*,ex*,s*}/
drwxr-xr-x 2 _chrony     _chrony  4096 Jul 22  2017 chrony/
drwxr-s--- 2 Debian-exim adm      4096 Oct 11 00:00 exim4/
drwxr-xr-x 2 stunnel4    stunnel4 4096 Jul 16  2019 stunnel4/

Most of the group ownerships are root or adm.  

root@joule:/var/log# ls -ld *
-rw-r--r-- 1 root        root         436 Oct 11 13:03 alternatives.log
drwxr-x--- 2 root        adm         4096 Oct 11 00:00 apache2
drwxr-xr-x 2 root        root        4096 Oct 11 13:03 apt
-rw-r--r-- 1 root        root        5831 Oct 11 13:03 aptitude
