Appendix A2 pertains to which type of security protocol?

Appendix A2 specifically addresses the requirements for SSL (Secure Sockets Layer) and early TLS (Transport Layer Security). This appendix outlines the necessary measures and protocols ensuring secure transactions over a network. As SSL and early TLS are integral to establishing secure connections and safeguarding data in transit, the guidelines set forth in this appendix are critical for organizations seeking to bolster their cybersecurity posture in relation to encrypted communications.

The focus on SSL and early TLS is essential, especially considering previous vulnerabilities and the ongoing evolution of security protocols. Understanding and implementing the requirements set out in this appendix helps organizations maintain a high standard of encryption and protect sensitive information from unauthorized access.

The other options, while relevant to various aspects of cybersecurity, do not align with the specific focus of Appendix A2. Shared hosting security relates to securing multiple websites hosted on the same server. Audit logging mechanisms involve recording and analyzing access and modifications to systems. Firewalls and intrusion detection systems (IDS) pertain to network security measures but do not encompass the encryption protocols discussed in Appendix A2.
