Firepower initial configuration as IPS

[nikolag21]

Hi all

We are using ASA 5500-X firewalls with firepower services. They are installed and active in our network. During the FMC installation, default Access Control Policy is define with default action "Intrusion prevention: Balanced Security and Connectivity". We want to use firepower as an IPS, so i have few questions regarding initial configuration.

 Is the system works as IPS as it is configured now with only default action "Intrusion prevention: Balanced Security and  Connectivity" set?

 Do we need to create custom intrusion policy and choose it in the default action of the default access control policy?

 Should we first set default action "Network Discovery Only" and then switch to Intrusion prevention?
    

We have created custom intrusion policy with default configuration (Drop when inline, Base policy: Balanced Security and Connectivity). When we try to apply this policy in access control policy we are getting "No access control rules configured. Improve performance by setting this access control policy's default intrusion policy and variable set (pre-rule inspection) identically to its default action intrusion policy and variable set (post-rule inspection).

Thanks in advance!

Hi,

did you create Access Policy and selected the inspection using the policy you created? like the access policy below?

We have one Access Control Policy which was created during the installation process. There are no rules added until now and just set default action "Intrusion Prevention: Balanced Security and Connectivity". We didn't create newer policy afterwards.

You can add new policy in access rules

source inside destination outside

then enable the inspection as in the image and select your ips policy

that should be it
