What does a layered defense strategy in cybersecurity entail?

• A. Using only one protective layer
• B. Providing multiple layers of protection
• C. Exclusive reliance on software firewalls
• D. Strictly enforcing user access policies

Answer: (B)

A layered defense strategy in cybersecurity involves implementing multiple layers of protection to secure systems and data from various threats. This approach recognizes that no single security measure is foolproof and that combining different security controls can enhance overall protection. By providing multiple layers of protection, organizations can address different types of threats, reduce vulnerabilities, and create redundancy in their security measures. For instance, a layered defense might combine firewalls, intrusion detection systems, antivirus software, encryption, and security awareness training for employees. Each layer serves a unique purpose, and together they provide robust security against potential attacks. The other choices highlight various security practices but do not align with the core principle of a layered defense strategy. Utilizing only one protective layer is insufficient for comprehensive protection, reliance solely on software firewalls ignores other critical security measures, and enforcing user access policies, while important, does not constitute a layered security approach by itself.
