Who's Within Your Firewall?

Use ExtraHop Reveal(x) with Palo Alto Networks to detect and contain late stage attacks

While opportunistic attacks are easily blocked, targeted and advanced attacks need multiple indicators to contain and disposition confidently. Identifying activities across systems, segments, applications, and users takes skill and time, usually more time than the attack's own successful execution.

This week at Palo Alto Ignite, we're excited to demonstrate a new integration that shows the power of network prevention, detection, and response working together in an integrated workflow. As part of the Palo Alto Networks Application Framework, ExtraHop's forthcoming Palo Alto integration takes advantage of Palo Alto's cloud-based Application Framework to capture firewall and threat events with a high risk score and hand off for contextual analysis in ExtraHop Reveal(x). This integration will provide a short-cut for investigations and short-circuit attacks throughout the attack chain.

With ExtraHop metrics and records correlated with firewall and threat data, users have access to rich and real-time data about activities within the network during the later stages of an attack. Unlike the limitations of the L2-L4 connection logs that the Security Operations Center (SOC) would typically get from a firewall, Reveal(x) captures, decodes, reassembles, structures, and indexes L2-L7 data for more than 50 protocols, showing an entire session with its component transactions within one record. This context of interactions – methods used, files accessed, systems involved – provides unique visibility to support live investigation and threat hunting:

For example, a device making calls to known bad websites or communicating on unusual ports might be quarantined by the Palo firewall. A log for the event is passed to ExtraHop Reveal(x) to spark an analyst to explore East-West activities, such as connections to databases, application interactions, port scans, and lateral movement. By identifying the host's other actions, the analyst can scope out the progress and intent of the attack and identify other systems that may have also been compromised:

Response activities can feed directly back to Palo Alto systems, to ticketing and case management systems, or into an orchestration. At Palo Alto Ignite, ExtraHop is also demonstrating integration and containment using Phantom and the Palo Alto Phantom app.
