Chapter 3 Setting Up the Sensor

Configuring TLS

Step 4 Verify that the host was added.

sensor(config)# exit

sensor# show tls trusted-hosts

10.89.146.110

sensor#

Step 5 View the fingerprint for a specific host.

sensor# show tls trusted-hosts 10.89.146.110

SHA1: B1:6F:F5:DA:F3:7A:FB:FB:93:E9:2D:39:B9:99:08:D4:47:02:F6:12 sensor#

Step 6 Remove an entry from the trusted hosts list.

sensor# configure terminal

sensor(config)# no tls trusted-host 10.89.146.110

Step 7 Verify the entry was removed from the trusted host list. The IP address no longer appears in the list.

sensor(config)# exit

sensor# show tls trusted-hosts

No entries

Displaying and Generating the Server Certificate

A TLS certificate is generated when the sensor is first started. Use the tls generate-keycommand to generate a new server self-signed X.509 certificate. The IP address of the sensor is included in the certificate. If you change the sensor IP address, the sensor automatically generates a new certificate.

Caution The new certificate replaces the existing certificate, which requires you to update the trusted hosts lists on remote systems with the new certificate so that future connections succeed. You can update the trusted hosts lists on remote IPS sensors using the tls trusted-hostcommand. If the sensor is a master blocking sensor, you must update the trusted hosts lists on the remote sensors that are sending block requests to the master blocking sensor.

To generate a new TLS certificate, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Generate the new certificate.

sensor# tls generate-key

SHA1 fingerprint is 4A:2B:79:A0:82:8B:65:3A:83:B5:D9:50:C0:8E:F6:C6:B0:30:47:BB
