CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 37

Which of the following is a technique used for modifying messages, providing Information and Cyber security, and reducing the risk of hacking attacks during communications and message passing over the Internet?

Answer options

• A. Risk analysis
• B. OODA loop
• C. Cryptography
• D. Firewall security

Correct answer: C

Explanation

Cryptography is the correct answer as it specifically deals with securing messages and information, making them unreadable to unauthorized users. The other options, while related to security, do not directly modify messages or provide direct protection against hacking during communications. Risk analysis focuses on identifying threats, the OODA loop is a decision-making process, and firewall security is about controlling network traffic rather than modifying messages.
