Which acronym represents the Certified TEMPEST Technical Authority?

The acronym that represents the Certified TEMPEST Technical Authority is CTTA. This designation is specific to individuals who have completed the necessary training and certification to assess and manage the security of systems that handle sensitive information, particularly in relation to unintentional emissions and the risk they pose to security. The CTTA certification signifies a specialized level of expertise in understanding and mitigating the risks associated with TEMPEST threats, which are critical for maintaining the confidentiality of sensitive information in various environments.

The other acronyms provided are not recognized in the context of TEMPEST training or certification. CPTA, for instance, does not align with any official TEMPEST-related credentialing, and both CETTA and CTO refer to different concepts or authorities unrelated to the Certified TEMPEST Technical Authority. This clarity helps reinforce the importance of accurate terminology within the specialized field of information security concerning sensitive data management.
