When the importance of confidentiality, integrity, and availability is considered equal, employing multi-layered security controls across all platforms is the most suitable approach. This strategy embraces the principle of defense in depth, which advocates for the implementation of various security measures that collectively address potential vulnerabilities and risks. Utilizing multiple layers of security helps ensure that if one layer is compromised, additional layers can provide protection, thereby safeguarding the fundamental principles of confidentiality, integrity, and availability. This approach ensures redundancy and enhances overall security posture, accommodating various threats that may target different aspects of security. The other options, while beneficial in specific contexts, do not provide the comprehensive coverage necessary when all three security principles carry equal weight. Strong firewalls primarily protect against unauthorized access but may not address all aspects of security effectively. End-to-end encryption is vital for maintaining confidentiality but overlooks measures for integrity and availability. A comprehensive incident response plan is crucial for responding to security breaches but does not proactively ensure security across all platforms. Therefore, the multi-layered security approach is best suited for a balanced and thorough defense strategy.
