NIST 800-45 pertains to which domain?

Explanation:
NIST SP 800-45 is about securing electronic mail. It lays out guidelines for the design, implementation, and operation of secure email systems—covering how mail servers and clients interact, how to protect message contents in transit and at rest, and how to use authentication and encryption (like TLS) to defend against spoofing, phishing, and malware delivered by email. This focus on email communications makes the mail domain the best fit. It isn’t primarily about securing websites, managing user identities across systems, or handling log data, which are the concerns of other domains.
