CISCO ASA RULES OR USE CASE

Hi Guys,

I am new to fortisiem, i have question, currently our Fortisiem monitor Cisco ASA firewall, but as for now it did not flag any rules from Fortisiem.

It is i have to manually create rules for any security incident for Cisco ASA? If anyone could share rules for  ASA or any use case that you guys used.

Hi Muhammad,

There are some specific rules where we mention ASA events by name.

  • Successful VPN Logon From Outside My Country
  • Startup Config Change: with login
  • Running Config Change: with login info
  • Heavy TCP Port Scan: Single Destination
  • Permitted Blacklisted Source
  • Denied Blacklisted Source
  • Permitted Blacklisted Destination
  • Denied Blacklisted Destination

FortiSIEM also categorises Events under different Groups (you can see this under Resources / Event Types) and you will find Rules referencing Event Type Groups rather than individual events. For example "Sudden Increase In Firewall Permitted Outbound Traffic To A Specific TCP/UDP port" rule references the Event Type Group "Permitted Traffic" and that group contains Cisco ASA events (about 20).

Thanks

Dan

Muhammad,  

You can create a Rule that notifies you when people change Rules.  Helpful for finding when things have been modified:
IF System Event Category = 2 AND Event Type IN PH_AUDIT_OBJECT_CREATED, PH_AUDIT_OBJECT_DELETED, PH_AUDIT_OBJECT_UPDATED AND OS Object Type = Rule
WHERE COUNT(Matched Events) >= 1
GROUPBY User,Object Name,Organization Name
