log permissions


I have a slink->potato->woody server, and I am a little concerned about the permissions some of the log files in /var/log have.

There are too many to list, but here are some:
-rw-r--r--    1 root     root      8232348 Nov  3 06:43 tripwire
-rw-r--r--    1 root     root        10152 Nov  3 14:49 wdm.log
-rw-r--r--    1 root     root            0 Nov  3 06:26 mysql.err
-rw-r--r--    1 root     adm             0 Oct 29 06:47 cfingerd.log
-rw-r--r--    1 root     root         8483 Oct 22 12:42 dmesg
-rw-rw-r--    1 root     utmp       320908 Nov  3 16:43 lastlog
-rw-r--r--    1 root     root       947139 Nov  3 16:36 nmb

why are these files read by all? I have "normal" users on my system, and although I trust them, these kinds of permissions make me feel a little paranoid. ie: they could be used by someone to investigate system use, etc..
