Effective CISSP Questions

Your web server responds to the customer’s browser with a raw HTTP 500 message. To avoid disclosing too much system information and improve user experience, which of the following is the best solution? (Wentz QOTD)
A. Input validation
B. Bound checking
C. Exception handling
D. Change management

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is C. Exception handling.

HTTP status code 500 means “Internal Server Error,” typically caused by program error or exception. If the exception is not handled appropriately and the system setting is not configured properly, the raw error message may respond to the clients that may disclose too much information or lead to a data breach, as the following diagram shows. Exception handling and appropriate configuration avoid this situation.

Raw error message because of inappropriate system configurations
