Cisco pxGrid Integration
Rapid Response Capabilities using Cisco pxGrid
Cisco pxGrid
With Cisco pxGrid (Platform Exchange Grid), your multiple security products can now share data and work together. This open, scalable, and IETF standards-driven platform helps you automate security to get answers and contain threats faster.
Please Note:
The integration is for pxGrid 2.0 and compatible with Cisco ISE 2.4 and above.
The below configuration works without certs for now. Support for Certs will be added soon.
Blusapphire integration with Cisco pxGrid
1. Provide contextual information in BluSapphire UI, using session information provided by Cisco ISE.
2. Provide quarantine action on an end-point using the ANC policy.
Configuration
Registration using username and password.
1. 
Open Blusapphire UI, From Settings →Integrations open Cisco pxGrid registration page.
2. Enter the client hostname in Client Node, Enter pxGrid Nodes in the pxGrid Nodes text area and click on submit button to save the Client Name and pxGrid Nodes.
3. HA failover can be done by entering two pxGrid Nodes. BluSapphire connects with both the nodes simultaneously. Initially, the first node/primary node is considered the active node. If the primary node goes offline, the secondary node is marked as the active node. If the primary node comes back online then it will be automatically marked as the active node. Data will be processed from the current active node only to avoid deduplication.
4. Click on Register button to Initiate client registration using username/password in Cisco ISE.
5. Click on the Registration status button to view the status of registration.
6. 
If the registration status is shown as Pending, seek approval from Cisco ISE Administrator. If the registration status is shown as Enabled then the registration process has completed successfully.
7. For approving client on Cisco ISE, Login as Administrator and Open the Cisco ISE --> pxGrid page to approve the pending registration.
8. 
Look for the client registration detail in Cisco ISE -> pxGrid with the status show as pending.
9. Now, select the client and click on approve.
10. 
Once approved, go to Cisco ISE -> pxGrid -> Web Clients and verify the client status is shown ON.
11. 
Go back to Blusapphire UI and check the Registration Status. The status would show Enabled if registration was successful.
Create ANC Policy
To create ANC Policy, Login to Cisco ISE as an administrative user and do the following activities
a. 
Open Operations -> Adaptive Network Control -> Policy List.
b. 
Click on Add, to create a new Policy with required actions.
c. 
After click on Add, it will display the following form.
d.
