Sample Review Questions and Answers:

1. Question: What is the primary purpose of implementing multifactor authentication (MFA) in an organization?

   • Answer: MFA enhances security by requiring multiple forms of verification, thereby reducing the risk of unauthorized access due to compromised credentials.

2. Question: Which of the following is a symmetric encryption algorithm?

   • A) RSA
   • B) AES
   • C) Diffie-Hellman
   • D) ECC
   • Answer: B) AES

3. Question: In the context of incident response, what is the primary objective during the containment phase?

   • Answer: The primary objective is to limit the scope and impact of the incident to prevent further damage or data loss.

4. Question: Which access control model is based on the classification of information and the clearance of users?

   • A) Discretionary Access Control (DAC)
   • B) Mandatory Access Control (MAC)
   • C) Role-Based Access Control (RBAC)
   • D) Attribute-Based Access Control (ABAC)
   • Answer: B) Mandatory Access Control (MAC)

5. Question: What is the primary function of an Intrusion Detection System (IDS)?

   • Answer: An IDS monitors network traffic for suspicious activity and alerts administrators to potential security breaches.

6. Question: Which cryptographic algorithm is commonly used for securing web communications?

   • A) RSA
   • B) AES
   • C) DES
   • D) SHA-256
   • Answer: A) RSA
