Which acronym stands for the protocol used to synchronize time across devices?

• A. NIST
• B. NTP
• C. NMAP
• D. DNS

Answer: (B)

Accurate time across devices is essential for reliable logging, incident response, and certificate validation in security environments. The acronym for the protocol used to synchronize clocks is NTP, the Network Time Protocol. NTP distributes time from reference clocks (such as atomic clocks or GPS) through a hierarchical model to networked devices, helping clocks stay aligned within milliseconds depending on network conditions. This alignment makes logs and security events comparable across systems, which is crucial for accurate auditing and forensic analysis in PCI DSS contexts. Other terms are not time-synchronization protocols: NIST is a standards body, NMAP is a network scanning tool, and DNS translates domain names to IP addresses.
