Answer :

Final answer:

When correlating an event timeline using a SIEM, you need to account for Time Synchronization and Event Sequencing. Time Synchronization ensures all system clocks are coordinated while Event Sequencing allows for events to be accurately ordered and analyzed.

Explanation:

When correlating an event timeline using a SIEM (Security Information and Event Management) system, you need to primarily consider two factors: Time Synchronization and Event Sequencing.

Time Synchronization refers to the process of ensuring all system clocks within a network are synchronized. This is crucial as it allows for events to be accurately aligned and analyzed chronologically. Without synchronized time, it is challenging to accurately correlate events.

Event Sequencing refers to the order in which events have occurred. This allows for a more in-depth analysis of a security event by presenting a chronological sequence of actions that led to the event. It is essential to maintaining the correct order of events to identify patterns and potentially establish cause and consequence relationships.
