Temporal resolution is the ability of a monitoring system to distinguish events that happen close together in time. In cyber security, it describes how finely logs, sensors, packet captures, or endpoint tools record activity. High temporal resolution preserves the order and spacing of actions; low temporal resolution can merge them into one blurred record or miss short-lived events entirely.
This matters because many attacks are fast and staged in seconds or milliseconds. Brute-force login attempts, process injection, privilege escalation, command-and-control beacons, and lateral movement can all produce brief bursts of activity that are easy to hide if timestamps are coarse or delayed. Defenders use high-resolution telemetry, synchronized clocks, and detailed event collection to reconstruct attack chains accurately and detect patterns that would disappear in aggregated data. In practice, temporal resolution helps turn a vague alert into a usable timeline.
