Final answer:

In correlating an event timeline using an SIEM system, TimeStamp and Event Sequence are essential components to be considered. TimeStamp focuses on the precise time an event occurred, while Event Sequence gives insight into the order of events leading to a specific outcome.

Explanation:

When correlating an event timeline using a Security Information and Event Management (SIEM) system, two essential factors one should account for are TimeStamp and Event Sequence.

The TimeStamp is critical as it helps determine when exactly an event took place within the given network or system, serving to accurately place it on the timeline.

The Event Sequence on the other hand refers to the order in which events took place. It's crucial as it assists in unraveling the trail of actions leading to a specific outcome, such as a security breach, thus assisting in mitigation strategies and future prevention.
