Use Case #2: Network Isolation 

Use Case #2: Network Isolation 

The SOC can take network-based response actions by utilizing API response actions on network appliances. These include firewall, routers, management devices, etc.  

Typical Actions

  1. Isolate/Quarantine endpoint(s) from network
  2. Terminate network sessions
  3. Update geo-blocking per IP/MAC address

Default Playbooks

  1. XDR: Public to Private Exploit Anomaly 
  2. Further assessment of applicable use cases on a per client basis is required. 

What is Needed

  1. API Credentials
    1. Username/Password - for most Firewall vendors  
  2. API Root
    1. URL of the firewall (along with port in most cases)  
  3. Address Group
    1. Group name to which SOAR will add IPs  
    2. The groups need to be configured to drop packets from IPs that belong to this group in both directions (incoming/outgoing traffic)  
  4. IP Zone
    1. For some firewalls, we are required to know which interface we need to add these IPs: WAN or LAN.  
    2. In most cases, this is set to WAN but if not, confirm with the customer. 

Available Vendors

  2. CloudFlare 
  3. Cisco ISE 
  4. Juniper vSRX
