Managing Signature Package Upgrading Conflicts

Upgrading a Signature package from lower version to a higher version fails when an Access Control Policy and an Application Control Policy already exists and the Application Signature in the AVC Policy of lower version conflicts with the one in higher version. In such a case, SZ displays an error message. Perform the following procedure to avoid this error.

To overcome Signature Package upgrade conflicts:

Step 1: Delete the L3 Access Control Policy:

  1. Go to Security > Access Control > L3 Access Control.
    Note: For SmartZone 5.2.1 or earlier releases, select Firewall > L3 Access Control
  2. Take a note of the policy details that you want to delete; click Configure to get more details of the profile for future reference.
  3. Select the profile and click Delete.

Step 2: Delete the Application Control Policy:

  1. Go to Security > Application Control > Application Policy.
    Note: For SmartZone 5.2.1 or earlier releases, select Firewall > Application Control > Application Policy
  2. Take a note of the policy details that you want to delete; click Configure to get more details of the profile for future reference.
  3. Select the policy and click Delete.

Step 3: Upgrade the Signature Package

  1. Go to Security > Application Control > Application Signature Package.
    Note: For SmartZone 5.2.1 or earlier releases, select Firewall > Application Control > Signature Package
  2. Click Browse, and choose the Signature Package file.
  3. Click Upload.

After the Signature Package is successfully applied the package file name, file size and the version will be visible in the UI.

Step 4: Create a new L3 Access Control Policy with the details of the policy deleted.

Step 5: Create a new Application Control Policy with the details of the policy deleted.
