Which technology enables accurate timestamping of network events by synchronizing time across devices?

• A. Secure Sockets Layer
• B. Network Time Protocol (NTP)
• C. Dynamic Host Configuration Protocol
• D. File Transfer Protocol

Answer: (B)

Accurate timestamping across devices hinges on a reliable time synchronization mechanism. When logs from multiple hosts are analyzed, having aligned clocks lets you order events correctly and reconstruct what happened, which is crucial for incident response and forensics. The Network Time Protocol is specifically designed to synchronize clocks on computer systems over a network. It uses a hierarchical structure of time sources and servers, with clients periodically requesting time, measuring delays, and adjusting local clocks to minimize offset and jitter. This coordination typically achieves millisecond-level accuracy within a local network, ensuring that events recorded on different machines share a common timeline. The other options don’t provide this cross-device clock synchronization: Secure Sockets Layer (TLS) protects data in transit but does not synchronize time; DHCP assigns IP addresses and related network configuration but isn’t used to keep clocks in sync; FTP is a file transfer protocol and has nothing to do with timekeeping.
