100-160 Question 2
Single answerA company recently experienced a data breach due to an employee using the same password across multiple systems. As a cybersecurity support technician, which essential security principle should you prioritize to mitigate this risk?
- A
Implementing multi-factor authentication (MFA)
- B
Enforcing a strong password policy and regular password changes
- C
Enabling firewall rules for all external traffic
- D
Conducting regular phishing awareness training
Show answer and explanation
Correct answer: B
Explanation
Password reuse is a common vulnerability that can lead to data breaches if credentials are compromised. Enforcing a strong password policy and requiring regular password changes ensures employees use different and secure passwords for each system, reducing the risk of unauthorized access. While other options enhance security in different areas, they do not specifically address the issue of password reuse.
- A. Incorrect.
Implementing multi-factor authentication (MFA) adds an extra layer of security, but it does not directly address the issue of password reuse across multiple systems.
- B. Correct.
Enforcing a strong password policy and regular password changes directly mitigates the risk of password reuse, ensuring that employees use unique and secure passwords for each system.
- C. Incorrect.
Enabling firewall rules for external traffic enhances network security but is not directly related to mitigating the risks associated with password reuse.
- D. Incorrect.
Phishing awareness training is essential for preventing social engineering attacks but does not address the issue of password reuse.
