Name a type of digital evidence aside from data stored on computers.

Network traffic logs serve as a critical type of digital evidence that offers insights into the data being transmitted across networks. These logs can capture details about the source and destination of data packets, the protocols being used, and the time of transmission. Analyzing network traffic can reveal patterns of behavior, unauthorized access attempts, or data exfiltration activities, making it invaluable in forensic investigations.

Internet activity logs document user actions and interactions with web resources, which can help establish timelines and user behaviors. Email correspondence, while significant, is a subset of communication data and often stored on computers or servers. Cryptographic keys, while essential for security, do not represent events or interactions but rather tools for securing data. Each of these choices illustrates different facets of digital evidence, but network traffic logs stand out for their ability to trace real-time communication and activity networks beyond individual devices.
