All, In addition to your wonderful suggestions, I would like to point out one more item that must be performed when hardening a Linux, or any other, system - and that is specifically hardening the TCP/IP stack. Although this step may sound unwanted or marginal, it can save you a lot of headaches sifting through useless looking NIDS signatures!! Some good suggestions are provided at http://www.cromwell-intl.com/security/security-stack-hardening.html http://www.securityfocus.com/infocus/1729 Another suggestion - and I do not wish to start a religious war on this one, given the varying and normally limited amounts of time admins usually have - is to use a honeypot, perhaps even a virtual one with VMs. Just my 2pence -CBC
