Some small security settings I've done

ubuntu_demon

Hi,

I've done some small security settings I think are important to do.

sudo find / -type f -perm 6000 -ls

finds programs that have the s bit set. I discoverd a lot of games had this bit set. I removed the s bit from them.

I have two ext3 partitions for ubuntu : / and /home
I set /home to : defaults,nosuid,nodev in /etc/fstab

chattr +i /bin/login (chattr -i /bin/login if there is an security update for it)

chmod 751 /var/log /etc/logrotate.d
chmod 640 /etc/syslog.conf /etc/logrotate.conf
chmod 640 /var/log/*.log

chmod -s /bin/at (users can use crontab)

What do you guys think ?
