The major capacities for a SIEM solution include data collection, caring data, and the process of identification of avaricious or strange activity. These actions allow to process all forms of data analysis and can have a straight impact on how effectively an organization can search and access its data.

Once the data has been ingested and normalized, the SIEM software correlates events across all of the data in aggregate to identify patterns of compromise and alert the end user to suspicious activity.

SIEM technology can reside either on personal hardware or it can be in the cloud. The main advantage is that it will collect data from variety data sources.

SIEM can be described as two technologies:

1. Security information management (SIM). Collection of data from log files for analysis and report on security alarms and potential threats.
2. Security event management (SEM). This allows to provide a real-time system monitoring, including notifications for network IT specialists about important issues and potential risks.

The security information and event management process can be broken down as follows:
Policies – Data consolidation and correlation – Notifications.
