A company's Chief Information Security Officer requires that servers and firewalls have accurate time stamps...

The correct solution is NTP (Network Time Protocol). Accurate timestamps across servers, firewalls, and network devices are critical for correlating logs during incident response. NTP synchronizes device clocks to a trusted time source, ensuring consistency across the network.

A. Syslog centralizes logs but does not synchronize time.

B. SMTP is email transfer, unrelated to time.

D. SNMP monitors devices but does not correct time discrepancies.

By implementing NTP, analysts can ensure that logs from different devices are time-aligned, which is essential for reconstructing attack timelines and detecting anomalies.
