SIEM: Security Information and Event Management (SIEM) is a software solution that aggregates and analyzes activity from many different resources across your entire IT infrastructure.
How do SIEM works?
It works by collecting log and event data generated by an organizations applications, security devices and host systems and bringing it together into a single centralized platform. SIEM gathers data from antivirus events, firewall logs and other locations; it sorts this data into categories, for example : malware activity and failed and successful logins.
SIEM tool it identifies threat through a network security monitoring, which generates an alert and identifies a threat level based on predetermined rules set. Ex: If some user tries to log into an account 10 times in 10 minutes that is okay, but 100 times in 10 minutes might be flagged as an attempted attack.
By this, it detects threats and creates security alerts. SIEM’s custom dashboards and event management system improves investigative efficiency and reduces time wasted on false positives.
The threat detection element itself can help to detect threats in emails, cloud resources, applications, external threat intelligence sources and endpoints. This can include user and entity behaviour analytics (UEBA) which analyzes behaviours and activities to monitor for abnormal behaviours which could indicate a threat. It can also detect behaviour anomalies, lateral movement and compromised accounts.
