Why do we need SIEM?
SIEM is significant because it makes it easier for businesses to manage security by filtering large volumes of data and prioritizing security alerts generated by the programme. Organizations can use SIEM software to detect incidents that might otherwise go unnoticed. The software looks at the log entries to see if there are any indications of suspicious activity. Furthermore, because the system collects data from several sources across the network, it can reconstruct the timeline of an assault, allowing a corporation to understand the nature of the attack and its financial impact. A SIEM system can also assist a company in meeting compliance obligations by automatically providing reports that incorporate all of the documented security events from all of these sources. The organization would have to manually collect log data and generate reports if it didn’t have SIEM software. A SIEM system also improves incident management by allowing a company’s security staff to trace an attack’s path across the network, identify compromised sources, and give automated capabilities to stop attacks in progress.
