Not getting IPS events on Firepower Management Center

msantiveri
Level 1
Level 1

Hello,

I have 3 SFR modules on monitor-only mode within a virtualized ASAs registered on a Cisco Firepower Management Center for VMWare 6.0.1 . I can see normal traffic statistics on the dashboard but even I tuned signatures to generate IPS alerts for any ICMP echo reply I don't see anything.

The licenses are applied, access policy is applied and intrusion policiy is also created and linked to the access policy on the default action.

Could anyone help me to find where the problem is?

Relevant configuration on virtual firewall:

class-map global-class
 match any

policy-map global_policy
 class global-class
  sfr fail-open monitor-only

MUA-FW1/ACCESS# sh service-policy sfr

Global policy:
  Service-policy: global_policy
    Class-map: global-class
      SFR: card status Up, mode fail-open monitor-only
        packet input 0, packet output 626950891, drop 0, reset-drop 0

MUA-FW1/ACCESS# sh module

Hi, 

 

We would suggest you to follow below steps to verify if IPS policy is working fine or not.

 

- Modify the intrusion policy in use and enabled the portscan detection / ICMP detection snort id 408.

- Assign a Network Analysis to the Access Control policy in use on the FirePOWER Management Center, and adjust the preprocessor settings.

-after deployment of the policy, initiate the traffic for ICMP and verify under intrusion events.

 

Regards

Jawed
