Secure Network Administrationintermediate
Arrange the steps for implementing a new firewall security policy rule in the correct chronological order, from initial creation to deployment.
Answer
Create a new rule entry in the firewall security policy interface, Define the traffic match conditions, including source, destination, and service, Specify the enforcement action and logging settings for matching traffic, Position the rule at the appropriate priority level in the rulebase, Commit the configuration changes to apply the rule to the firewall dataplane
Explanation
### Why this is right
The rule must first be opened for editing, then its traffic direction and matching fields can be specified. The Allow action and save operation complete the rule so it can be verified.
### The order
1. **Open Policies > Security and add a rule**: This creates the rule entry to configure.
2. **Set the source zone to Internal**: This identifies where permitted traffic originates.
3. **Set the destination zone to DMZ**: This identifies where the permitted traffic is headed.
4. **Set the application and service fields as instructed**: These fields narrow or describe matching traffic.
5. **Set the action to Allow and save the rule**: The firewall can then permit traffic that matches the configured rule.
### Terms
- **Security policy**: A firewall rule that matches traffic attributes and applies an action.
### Remember
Configure the direction and match conditions before saving the action that applies to them.
