Add a Security Rule to a Firewall Policy

• Console
• CLI
• API

• 1. On the navigation menu, select Identity & Security. Go to Firewalls, select Network Firewall Policies.
  2. Select the policy.
  3. Under Policy resources, select Security rules.
  4. Select Create security rule.
  5. Enter the information for the security rule:
     • Name: Enter a name.
     • Match condition: Specify that the rule matches Any address, application, service, or URL. Alternatively, specify source and destination addresses, applications, services, or URLs that much match for the rule to take effect. You can select any of the lists you created. If you haven't previously created any lists, select Create address list, Create application list, Create service list, or Create URL list and see Create a URL List.
     • Rule action: Specify the action that you want to take if the match condition is met:
       • Allow traffic: The traffic is allowed to proceed.
       • Drop traffic: The traffic is dropped silently, no notification of reset is sent.
       • Intrusion detection: Logs the traffic
       • Intrusion prevention: Blocks the traffic.
         Important
         
         If you want to use intrusion detection and prevention, you must also enable logging. See Logging Firewall Activity.
       • Reject traffic: The traffic is dropped and a reset notification is sent.

     • Rule order: Select the position of the rule in relation to other security rules in the policy. The firewall will apply the security rules in the specified order from first to last. You can specify the following rule positions:
       • First rule in the list
       • Last rule in the list
       • Custom position (Only enabled if you create more than one security rule.)
       If you select Custom position, specify whether you want this rule to come Before an existing rule, or After an existing rule. Then, specify the existing rule you want the new rule to come before or after.
  6. Select Create security rule.

• Use the network-firewall security-rule create command and required parameters to create a decryption rule:

  oci network-firewall security-rule create --name my_security_rule --network-firewall-policy-id network firewall policy OCID
  --action ALLOW --condition '[{"sourceAddress":"IP_address"}]' ...[OPTIONS]

  For a complete list of parameters and values for CLI commands, see the CLI Command Reference.
