We are continuously receiving following event on Cisco PIX firewall "Deny IP spoof from (0.0.0.0) to x.x.x.x on interface intfx" .
Request you to reply to the following queries:
1. Whether the event specified can be classified as an attack?
2. Whether relevant IPS signatures available for detecting such events in the IPS device?
3. Will these events get triggered without enabling IP verify reverse-path command on the firewall?
Thanks & Regards,
