Note

The Signature Set version 11.9.0.21 bundled with this release of Manager contains only Digital Envoy database for IP address to Geolocation Mapping. This signature set version will not be a part of the publicly available signature sets.

Note

When you upgrade the Sensor software version to 11.1.5.2, you must also upgrade the corresponding Manager software version to 11.1.7.3.

For more information, see Manager and its compatible Sensor software versions in Trellix Intrusion Prevention System 11.1.x Product Guide.

Note

The Manager software 11.1 is not supported on Windows-based Appliance. The end-of-life for Windows-based Appliance has been declared and the end-of-life is on 01-Apr-2023. Trellix recommends you to migrate from Windows-based Appliance to Linux-based Appliance.

Note

If you have a 9.x Manager managing 9.x NTBA, you should consider upgrading 9.x Manager to 10.1 or 11.1. If you plan to upgrade the Manager to 11.1, you need to first upgrade it to 10.1.7.65 and then to 11.1.

Upgrade support

Trellix regularly releases updated versions of the signature set. You can choose to automatically download and deploy the signature set in the Manager.

Upgrade paths for Manager software versions

Note

Before you start upgrading to the latest 11.1 Manager version, ensure that you do not change the timestamp and timezone values of the Manager.

Caution

The Manager software supports only TLS 1.2 ciphers for Manager and Sensor communication.

Caution

If you are currently using Sensor software version that supports TLS 1.0 and you upgrade your Manager software to 10.1.7.65 or above, the communication between the Manager and Sensor will fail. Therefore, you must first upgrade the Sensor to a software version that supports TLS 1.2 and later upgrade your Manager to 10.1.7.65 or above. Post this, you may upgrade the Sensor to 10.1.5.190 or above.

For example, if you have a NS9500 Sensor running on software version 9.2.5.52 (TLS 1.0) and Manager software version 10.1.7.44, and you plan to upgrade the Sensor to 10.1.5.190 and Manager to 10.1.7.65, you must follow the upgrade path as listed below:

  1. Upgrade your NS9500 Sensor from 9.2.5.52 (Supports TLS 1.0) to 10.1.5.107 (Supports TLS 1.2).

  2. Upgrade the Manager from 10.1.7.44 to 10.1.7.65.

  3. Upgrade the Sensor from 10.1.5.107 to 10.1.5.190.

Similarly, if you have a NS9300 Sensor running on software version 9.2.5.72 (TLS 1.0) and Manager software version 10.1.7.44, you must follow the upgrade path as listed below:

  1. Upgrade your NS9300 Sensor from 9.2.5.72 (Supports TLS 1.0) to 10.1.5.106 (Supports TLS 1.2).

  2. Upgrade the Manager from 10.1.7.44 to 10.1.7.65.

  3. Upgrade the Sensor from 10.1.5.106 to 10.1.5.190.

Note

If you have Sensor software version that supports TLS 1.0, please refer to KB96194 and contact Trellix Support for assistance.
