default actions

The default action for a rule-based decryption policy determines how the system handles decryptable encrypted traffic that does not match any non-monitor rule in the policy. When you deploy a rule-based decryption policy without a decryption rules, the default action determines how all decryptable traffic on your network is handled. Note that the system does not perform any kind of inspection on encrypted traffic that the default action blocks.

To set the policy default action:

  1. Log in to the Security Cloud Control if you haven't already done so.

  2. Click Administration > Integrations > Firewall Management Center and choose Policies > Access Control > Decryption.

  3. Click Edit (edit icon) next to the name of the decryption policy.

  4. In the Default Action row, click one of the actions from the list.

Decryption policy Default Actions

Default Action

Effect on Encrypted Traffic

Block

Block the TLS/SSL session without further inspection.

Block with reset

Block the TLS/SSL session without further inspection and reset the TCP connection. Choose this option if traffic uses a connectionless protocol like UDP. In that case, the connectionless protocol tries to reestablish the connection until it is reset.

This action also displays a connection reset error in the browser so the users are informed that the connection is blocked.

Do not decrypt

Inspect the encrypted traffic with access control.
