Which NIST IR describes System and Network Security Acronyms and Abbreviations?

• A. IR 7581 - System and Network Security Acronyms and Abbreviations
• B. IR 7564 - Security Metrics
• C. IR 7816 - Computer Security Division Report
• D. IR 7359 - Information Security Guide for Gov Executives

Answer: (A)

This item tests your ability to identify the NIST publication that serves as a glossary for terms used in system and network security. The correct publication is the one explicitly described as System and Network Security Acronyms and Abbreviations, which is published as IR 7581. This IR is a reference that compiles the acronyms and abbreviations you’ll encounter in the field, making it the exact match for a question about a terms and definitions resource. The other publications cover different topics: one focuses on Security Metrics, another is a Computer Security Division Report on division-related topics, and the last is an executive guide for information security. Those are not about acronyms and abbreviations, so they don’t fit the question as precisely as the glossary IR.
