securing linux server - need some help
I got some tips about securing a linux server but I do not have enough knowladge to implement it..
Can anybody from this forum write shell commands to make this work>
1. The shared memory /dev/shm also is exploitable. It may be secured by unmounting it, changing it in /etc/fstab from defaults to nosuid,noexec and remounting it.
2. The /var/spool/samba and /var/spool/vbox and /usr/local/apache/proxy
directories may be exploited and you can safely just remove
world-writable permissions from them.
best regards
