Here is how to block Scanalert bots using csf.

wget -q -O- http://www.mcafeesecure.com/help/ScanIps.csv | awk 'NR < 4 { next } { print }' | cut -d"," -f1 | replace '"' '' — | sort -n > /etc/csf/csf.denyscanalert

To include these blocks in CSF, add this to /etc/csf.deny :

Include /etc/csf/csf.denyscanalert

and restart csf: service csf restart
