Securing Email with Cisco Email Security Appliance (SESA) — Question 63

A Cisco ESA administrator has several mail policies configured. While testing policy match using a specific sender, the email was not matching the expected policy.

What is the reason of this?

Answer options

• A. The “From” header is checked against all policies in a top-down fashion.
• B. The message header with the highest priority is checked against each policy in a top-down fashion.
• C. The “To” header is checked against all policies in a top-down fashion.
• D. The message header with the highest priority is checked against the Default policy in a top-down fashion.

Correct answer: A

Explanation

The correct answer is A because the Cisco ESA evaluates the 'From' header against policies in a top-down manner until a match is found. Options B, C, and D are incorrect as they either misstate the header being checked or the order of evaluation, which could lead to mismatches.
