What is a session ID in a log?¶

A session ID links activity within a technical session, which may represent authentication, a network connection or temporary application context. It does not uniquely identify a person.

Sessions persist, rotate and multiply¶

One user interaction can create several IDs, and an ID can continue across requests after original authentication. Refresh and rotation can change values. A session can be shared, copied, stolen or remotely controlled, while automation creates sessions without a human browser.

Trace session lifecycle and control¶

Identify creator and session type, beginning, expiry, refresh, rotation and invalidation. Preserve authentication, token, endpoint, network and application records and whether exports mask the ID.

Handle session tokens carefully where they remain sensitive credentials. Do not assume continuous legitimate use merely because later events share the same value.
