I may be getting a little paranoid lately, but I was wondering if the following script might be going a little overboard. I have 2 linux machines & a windows ME machine on my network along with a smoothwall firewall. I just got a p3 633 machine & am thinking about setting it up as a hidden (hopefully) central log server & would like to know if maybe I'm checking a few too many things when I run a security check on my systems - the following is a script that I'm testing for a single machine running on redhat 9 (can't upgrade quite yet because of 2 in house programs so).

#!/bin/bash
# Show startup time
date
# Start internet
/sbin/ifup ppp0

# synchronize system time
echo "Synching System Time"
rdate -s XXXXXXXX

# Update Antivir
echo "Updating Antivirus"
antivir --update

# Update Rkhunter
echo "Checking for rkhunter Updates"
rkhunter --update

# Stop Internet
/sbin/ifdown ppp0

# Run Rkhunter
echo "Running Rkhunter"
rkhunter --cronjob

# Run Tiger Security Check
echo "Running Tiger"
/usr/local/sbin/tiger

# Run chkrootkit
echo "Running chkrootkit"
/opt/templates/chk*/./chkrootkit -q

# Run Linux Security Auditing Tool
echo "Running lsat"
lsat --silent --exclude=/home/something/exclude

# Check for viruses
antivir / --allfiles -s -nolnk

# Show time again
echo "Showing Stop Time"
date

This reminds me of a recent post on cryptography. It basically boils down to what you use your computer for.

If you work for the FBI or a university CS department (notorious, of course, for clever students) then maybe not. If it's a computer in your kitchen used for downloading recipes, probably.
