Cisco ASA 5510 scanning error

Hi Vinod,

These logs are generated because of the threat detection enabled on the ASA, when the traffic hitting the firewall exceeds the limits set in those parameters, you will get these error messages.

To check threat-detection, you can do:

show run threat-detection

You can either remove it or tweak the paramaters a bit.

Thanks,

Varun
