i use macafee's firewall and a port checker that checks for any open ports on the system,the
firewall can log any attacks on arp,icmp,rip,pptp,.... i have set it to filter all trafic,allowed all arp
packets cause if i stop all arp packets i can not connect any where.
i also use eeye's iris for sniffin packets(the guard thing shows arp attack)
