Security information and event management
Activities can be monitored and customized rules can be created for event correlation to trigger alerts based on certain conditions from various log sources such as network devices, security devices, servers and antivirus. Some examples of customized rules to alert on event conditions involve user authentication rules, attacks detected and infections detected. Thresholds can be configured to trigger alerts based on the quantity of occurrences of events.
