Dynamic External Lists for Hostnames

L0 Member

Trying to figure out the best way to accomplish a task. 

  1. We have a "Suspicious" rule on our firewall that should be where we place hostnames for users that are observed to have questionable traffic.
  2. This will be a dynamic list that will be updated by adding/removing hosts at any given time depending on security alerts
  3. Since we use LDAP I know we can add the hosts directly to the rule

QUESTION: Has anyone used an External Dynamic List for hostnames to be added to the rule?


Thank you

It sounds like you have a few options here


1. Use Minemeld and point it to something you are using to host/build a list of hosts

2. Create a tag and dynamic group then add your objects and use the tag and build the policy using the group

3. Instead of using the user's source IP create a custom URL profile and add the nuisance sites into it then set that profile to block or continue


We are doing all of the above

To the best of my knowledge a tag and a dynamic address-group is going to be the cleanest way of doing this; hostnames are not currently a valid option when using an EDL.
