Sentinel IPS

Sentinel Intrusion Prevention Systems (IPS) is network security software that provides threat protection and visibility, threat detection and response, and improved network performance. You can send Sentinel IPS logs to InsightIDR for IDS events.

To get started:

  1. Create a Network Address Translation
  2. Configure Remote Logging in Sentinel IPS
  3. Create an IDS Event Source

Create a Network Address Translation

Network Address Translation (NAT) protects the identity of a network by controlling traffic on your network’s internal and public IP addresses. Learn more about NAT here: https://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/26704-nat-faq-00.html

Because your Sentinel IPS appliance usually has a public IP address and your InsightIDR Collector will have an internal IP address, you will likely need to configure NAT or port-forwarding rules on your firewall or networking device to ensure Sentinel IPS can forward traffic to the InsightIDR Collector.

On your firewall during port forwarding or NAT configuration, we also advise that you restrict the source IP address to that of the Sentinel lPS device to ensure the InsightIDR Collector is secure.

Configure Remote Logging

After you create a NAT, you must add the InsightIDR Collector as a remote logging host for Sentinel IPS.

To configure remote logging for Sentinel IPS:

  1. Sign in to your Sentinel IPS console.
  2. From the top menu bar, select Configuration > System Controls > Remote Logging.
  3. In the “IP Address” field, provide the IP address of your InsightIDR Collector.
  4. In the “Port” field, enter the unique port through which InsightIDR will accept the Sentinel IPS traffic.
  5. Optionally choose which protocol you want to use, UDP or TCP.
  6. Click the Save button.

For more information on Sentinel IPS configuration, you can read the user guide here: https://sentinelips.com/wp-content/uploads/2017/09/Sentinel4UserInterfaceGuide.pdf

Create an IDS Event Source

Now you can create an IDS event source and connect Sentinel IPS with InsightIDR.

To do so:

  1. From your dashboard, select Data Collection on the left hand menu.
  2. When the “Data Collection Management” page appears, click the Setup Event Source dropdown and choose Add Event Source.
  3. From the “Security Data” section, click the IDS icon. The “Add Event Source” panel appears.
  4. Choose your collector and select Sentinel IPS as your event source. You can also name your event source if you want.
  5. Choose the timezone that matches the location of your event source logs.
  6. Optionally choose to send unfiltered logs.
  7. Select Syslog as your data collection method and specify the port and protocol you configured in Sentinel IPS.
  8. Click the Save button.
