Answers

1. Answer: A

Explanation: The principle of least privilege is a fundamental security principle that dictates users should only have the minimum permissions required to perform their tasks. This minimizes the potential damage if a user account is compromised.

2. Answer: C

Explanation: While BCDR is a critical security concept, it is not explicitly covered in the CISSP CBK. The CISSP focuses on information security, and BCDR encompasses a broader range of business continuity considerations.

3. Answer: A

Explanation: Preventive controls are designed to stop security incidents from happening. Examples include access controls, firewalls, and intrusion detection systems.

4. Answer: D

Explanation: An MitM attack intercepts communication between two parties, allowing the attacker to steal data or impersonate one of the parties.

5. Answer: C

Explanation: Strong and unique passwords are essential for preventing unauthorized access. Users should avoid using the same password for multiple accounts and refrain from sharing passwords with others.

6. Answer: B

Explanation: Penetration testing is a controlled process where authorized experts simulate cyber attacks on a system to uncover vulnerabilities. By exploiting these weaknesses, they help organizations identify and fix security issues before malicious hackers can exploit them. This proactive approach strengthens the overall security posture of the system or network.

7. Answer: B

Explanation: Asymmetric encryption involves two keys: a public key, which encrypts data, and a private key, which decrypts it. Data encrypted with the public key can only be decrypted with the corresponding private key, ensuring secure communication.

8. Answer: B

Explanation: SIEM systems aggregate security logs from different devices and applications, allowing for centralized monitoring and analysis of security events.

9. Answer: A

Explanation: Phishing attacks attempt to trick users into revealing sensitive information or clicking malicious links by posing as legitimate entities.

10. Answer: B

Explanation: The CIA triad represents the three core security objectives: confidentiality (ensuring data privacy), integrity (maintaining data accuracy and completeness), and availability (ensuring authorized access to data).

11. Answer: B

Explanation: Risk management aims to identify, assess, and mitigate risks to an acceptable level rather than eliminating all risks. This approach recognizes that complete risk elimination is often impractical or impossible, and attempting to do so could be overly costly or disruptive. Instead, the focus is on managing risks effectively to ensure they are within acceptable thresholds while enabling the organization to pursue its objectives efficiently.

12. Answer: B

Explanation: This classification system categorizes data based on its sensitivity and importance, guiding organizations in implementing suitable security measures, access restrictions, and protective measures tailored to each category's needs.

13. Answer: B

Explanation: Firewalls are security barriers that monitor and control network traffic based on predefined rules, safeguarding networks from unauthorized access and cyber threats. They examine data packets and decide whether to allow or block them based on factors like source/destination addresses, ports, and protocols.

14. Answer: C

Explanation: SMTP is commonly used for email communications. While it doesn't inherently provide security, extensions like STARTTLS can be used for encryption. Additionally, other email security protocols like SPF, DKIM, and DMARC are often implemented alongside SMTP to enhance security.
