What is one of the best practices for configuring the Aruba Firewall?

Using aliases when configuring the Aruba Firewall is considered a best practice because it simplifies management and enhances the clarity of firewall rules. Aliases serve as labels that can replace complex or lengthy IP addresses or port numbers, making the configuration more understandable and easier to maintain. This facilitates quick modifications, reduces the risk of errors when defining policies, and improves overall readability for administrators who may need to review or edit the firewall settings later.

Using aliases also allows for more organized rule sets, enabling easier audits and quicker responses to security incidents. Instead of having to sift through numerous IP addresses, an administrator can quickly understand the purpose of a rule if it’s defined with a meaningful alias, ultimately leading to better efficiency in firewall management.

The other options, while related to security, do not directly enhance the management and operational effectiveness of the firewall configuration in the same way that using aliases does.
