Mapping Cyber Vision properties to Cisco ISE attributes

You can see how Cyber Vision component properties are transmitted and mapped to Cisco ISE attributes for device integration. This action maintains accurate data transfer and enables proper policy and reporting functionality.

  • In Cyber Vision, a property is a piece of data that describes a device or component, such as its IP address or model name.

  • An attribute is a specific data element or field in a database or system used to store or reference information about an object. In Cisco ISE, an attribute is a field that records a property's value for use in policy rules, reporting, or integration.

Setup procedures

Custom hosts

A custom host is a network configuration entry that

  • enables direct mapping of hostnames to IP addresses,

  • enables communication between systems when DNS is unavailable, and

  • provides a manual method for hostname resolution.

DNS is a hierarchical, distributed naming system. It translates human-readable domain names (hostnames) into IP addresses. The system uses DNS servers within the network to perform name resolution automatically. When a device needs to communicate with another device by name, it queries the DNS server, which returns the corresponding IP address. DNS servers maintain databases of hostname-to-IP mappings and can cache responses to speed up subsequent queries.

If DNS is unavailable, configure custom hosts in both Cyber Vision Center and Cisco ISE. This ensures that services can communicate.

Comparison of custom host and DNS approaches

Term

Description

Usage scenario

Custom host

Manually configure hostname to IP mapping locally (for example, in the hosts file) to resolve names.

When no DNS server is available in the network.

Domain Name System (DNS)

The DNS is a distributed system that automatically resolves hostnames to IP addresses using DNS servers.

Standard method for hostname resolution in networks.

How custom host configuration works

Summary

Custom hosts enable direct hostname-to-IP resolution. This ensures communication between Cyber Vision Center and Cisco ISE in environments without DNS servers.

The key components involved in the process are

  • Custom host file: Contains manual hostname-to-IP mappings on both systems.

  • Cyber Vision Center: Uses the custom host file to resolve ISE hostnames.

  • Cisco ISE: Uses the custom host file to resolve Cyber Vision Center hostnames.

Workflow

The process involves these stages:

  1. Check if DNS is available in your network.
  2. If DNS is not available, add a custom host mapping entry (hostname-to-IP) in the hosts file on both Cyber Vision Center and Cisco ISE.
  3. Restart the required services to apply your host configuration changes.
  4. Use hostnames to communicate. Each system looks up its hosts file for resolution.

Result

Cyber Vision Center and Cisco ISE use hostnames to communicate directly when DNS is unavailable, resolving names with the custom host configuration.

Configure a custom host in Cisco ISE

Add a host to the Cisco ISE host table when DNS is not configured correctly.

Before you begin

Ensure secure SSH access is available to the Cisco ISE host.

Procedure

Step 1

Connect to the Cisco ISE host using SSH.

ssh admin@<ise-node-ip-address>

Step 2

Enter configuration mode.

configure terminal

Step 3

Replace the address and hostname with your information to add the custom host entry.

ip host <center-ip-address> <center-FQDN>

Step 4

When prompted, restart Cisco ISE to apply the changes.

You have added the custom host entry.


Note

The IP host function may not work with Cisco ISE version 3.3. For more information, see CSCwj05508.

What to do next

Restart Cisco ISE to apply your change. After the system restarts:

  • Form the Cisco ISE main menu, choose Administration > pxGrid Services > Client Management > Clients, and verify the host appears in the pxGrid Clients list.

  • Ping the host to verify connectivity.

Configure a custom host in Cyber Vision

Add a custom host entry and restart the pxGrid agent so that Cyber Vision integrates with Cisco ISE. Use this procedure if the environment lacks proper DNS configuration.

Perform this task when you need to manually add a custom host (for example, the Cisco ISE server) to the hosts file on Cyber Vision. This step ensures that the pxgrid-agent processes the change. Typically, this is required during initial integration with Cisco ISE or after a configuration change.

Before you begin

  • Ensure you have SSH root access to the Cyber Vision Center.

  • Obtain the IP address and hostname of the Cisco ISE server to add.

  • Ping the IP address from Cyber Vision to Cisco ISE and from Cisco ISE to Cyber Vision to confirm that the two systems can communicate.

Procedure

Step 1

SSH to the Cyber Vision Center using this command:

ssh root@<center-ip-address>

Step 2

Add the custom host entry by running:

echo "<ise-ip-address> ise.corp.sentryo.net" >> /etc/hosts

The pxgrid-agent restarts automatically. Cyber Vision successfully communicates with Cisco ISE.

What to do next

  • Approve the Cyber Vision integration request in Cisco ISE.

  • From the Cyber Vision main menu, choose Admin > Integrations > pxGrid/ISE and see Pull service status and Push service status, to verify Cyber Vision's integration status with Cisco ISE.

How Cisco ISE and Cyber Vision integration via pxGrid works

Summary

The integration of Cisco Identity Services Engine (ISE) with Cyber Vision using pxGrid enhances network security by providing detailed device visibility for improved profiling and dynamic policy enforcement.

The key components involved in the process are:

  • Cyber Vision: Collects and sends detailed asset and device attribute data to Cisco ISE.

  • pxGrid connection: Provides secure, real-time data exchange between Cisco ISE and Cyber Vision.

  • Cisco ISE: Receives, processes, and uses device attribute data for network access decisions.

Workflow

The integration workflow involves these sequential stages:

  1. Prepare Cisco ISE for pxGrid integration
    • Enable Cisco ISE to accept data from pxGrid partners.
    • Configure certificate management to enable secure communication. Use self-signed or external certificates as required.
      • Self-signed certificate: A self-signed certificate is a digital certificate signed by the same entity that creates it, not by an external Certificate Authority (CA). Cisco ISE generates a self-signed certificate during installation, which is used for admin access, inter-node HTTPS communication, and user authentication. For more information, see Generate a client certificate in Cisco ISE.
      • External certificate authority (CA): Certificates are issued and signed by a trusted third-party CA. This provides higher security and easier integration across multiple systems. If you want to use an external certificate authority instead of a self-signed certificate, see How external certificate authorities enable secure pxGrid integration.
  2. Register and configure Cyber Vision as a pxGrid client
    • Set up Cyber Vision as a pxGrid client.
    • Ensure Cyber Vision uses trusted certificates for authentication.
  3. Establish pxGrid secure connectivity
    • Create a secure pxGrid connection between Cisco ISE and Cyber Vision.
    • Validate certificate trust on both systems to ensure a trusted and encrypted data exchange.
  4. Enable pxGrid communication mechanism
    • In Push Mode, Cyber Vision initiates a connection to Cisco ISE (port 8910) and pushes asset data.
    • In Pull Mode, Cisco ISE connects to Cyber Vision (using its FQDN on port 8910) and pulls asset data. Ensure Cyber Vision’s certificate is imported into Cisco ISE for secure access.
  5. MAC aggregation in Cyber Vision
    • Cyber Vision consolidates components that share the same MAC address into a single endpoint.
    • Aggregated endpoint records contain merged properties, such as IP addresses and protocols.
    • Cyber Vision sends a maximum of two aggregated components per MAC address to Cisco ISE to prevent duplication.
  6. Data exchange and endpoint profiling
    • Cisco ISE receives detailed device and asset attribute data from Cyber Vision through pxGrid.
    • Cisco ISE processes this data to create or update endpoint profiling policies and improve policy enforcement.
  7. Certificate management for ongoing integration

Result

Cisco ISE automatically adjusts endpoint profiling and policy enforcement using up-to-date device information from Cisco Cyber Vision. This enhances security and operational efficiency.
