Firewall logs to ArcSight

I have a query regarding Cisco ASA, Palo Alto Firewalls integrating into arcsight.

In a scenario where there is no storage for storing the logs, and when these firewalls capture only live data. Can we integrate the live logs from firewalls in Arcsight?

In a single node  arcsight logger setup. You can configure your firewall to send syslog to a Arcsight syslog daemon connector instance, which run on the same Arcsight logger machine.  Set the connector instance forward those CEF events to the logger ( via smart message reciever (enabled by default). In most case you don;t need the firewall to keep a local copies of the log.

You can integrate them for sure. The logs are delivered from the application to an ArcSight syslog connector. Depending on the EPS you're expected to receive from these devices, you might have to consider loading a syslog load balancer. Keeping in mind, each connector should only handle at most 5k EPS.

Also, you will want to apply field based aggregation pretty quickly upon integration. This saves on resources, database storage/performance and of course event storage. If you need these best practice settings, I can provide them to you.
