    Hi,

    i use a pc a gateway plus email server and i was wondering how i could
    secure it better. Right now, i have snort, samhain, iptables firewall
    and logcheck installed. Nothing runs in a jail for the moment.
    I also haven't anything installed yet on my client pc to check the
    server. I think i will use SAINT for this.

    I'm currently going to install AIDE too and i was wondering about kernel
    patches. I've seen exec-shield, RSBAC and other kernel patches relating
    to ACL. (grsecurity).
    So i'm currently looking to install one (or a combination) of these.
    For instance, it seems to me that if you want buffer overflow protection
    and access control management, i would need to install exec-shield AND
    grsecurity together.
    RSBAC seems to provide several types of ACL but no buffer overflow
    protection?
    Does anybody have experience setting 1 of these up? Any good links?

    Thanks,
    Benedict
