Adding Application Signature Groups

Application identification supports custom application signatures to detect applications as they pass through the device. When you create custom signature groups, make sure that your signature groups are unique, by providing a unique and relevant name.

To create an application signature group:

  1. Select Configure > Shared Objects > Application Signatures.
  2. Click Create > Signature Group.
  3. Complete the configuration according to the guidelines provided in Table 1.
  4. Click OK to save the changes. If you want to discard your changes, click Cancel instead.

A new application signature group with your configurations is created. You can use this application signature group in firewall, NAT, and SD-WAN policies.

Table 1 provides guidelines on using the fields on the Create Application Signature Group page.
