Activate TLS inspection on Engines

Depending on the elements you select in the engine properties, you can activate client protection alone, server protection alone, or client and server protection together.

CAUTION:

Uploading TLS Credentials or a Client Protection Certificate Authority elements to the engine might enable decryption of TLS traffic that is not excluded from TLS inspection. The following configurations might enable decryption of TLS traffic:

  • Adding a Network Application that allows or requires the use of TLS to an Access rule
  • Selecting the Enforced option for Log Application Information in the Access rules
  • Enabling Deep Inspection in an Access rule if the Service cell contains a Network Application or a Service that does not include a Protocol Agent

Engine Editor > Add-Ons > TLS Inspection

Use this branch to activate TLS inspection. You can configure TLS inspection for client or server protection.

Note: These settings are not supported for Master Engines.
Option Definition
Client Protection Certificate Authority Select the Client Protection Certificate Authority element to use for client protection.
TLS Credentials Specifies the Server Protection Credentials elements that are used for server protection. Click Add to add an element to the list, or Remove to remove the selected element.
Check Certificate Revocation When selected, the Engine uses CRL or OCSP to check whether certificates have been revoked.
Decrypt All Traffic When selected, the Engine forces all traffic to be decrypted. When the checkbox is not selected, the Engine either decrypts or does not decrypt traffic according to the settings in TLS Match elements.
Cryptography Suite Set Specifies the TLS Cryptography Suite Set element that defines which cryptographic algorithms are allowed for TLS traffic that is decrypted for TLS Client Protection. Click Select to select an element.
