    What is a best practice to follow before tuning a Cisco IPS signature?

    • Disable all the alert actions on the signature to be tuned.

    • Disable the signature to be tuned.

    • Create a clone of the signature to be tuned.

    • Increase the number of events required to trigger the signature to be tuned.

    • Decrease the attention span (maximum inter-event interval) of the signature to be tuned

    Correct Answer
    A. Disable all the alert actions on the signature to be tuned.
    Explanation
    Before tuning a Cisco IPS signature, it is best practice to disable all the alert actions on the signature to be tuned. This is because tuning a signature involves making adjustments to the sensitivity or behavior of the signature, and if the alert actions are enabled, it could potentially generate unnecessary alerts or actions during the tuning process. By disabling the alert actions, it allows for a more controlled and focused tuning process without generating any unwanted alerts or actions.
