What Are SIEM and Log Management?
Although Security Information and Event Management (SIEM) and Log Management have similar appearances, they are each meant to fulfil different purposes within the realm of Cyber Security. The main objective of Log Management is to collect, store and structure logs from servers, applications, databases and networked devices. Log Management enables IT and Security to easily access historical logs when investigating an incident, troubleshooting issues with a system and preparing for audits/regulation reviews.
On the other hand, SIEM applies sophisticated analysis and
correlation methods to the data acquired through log management. It keeps track
of activities almost in real time, links different systems related actions, and
raises alarms in case of detection of any dubious activity. Log management
guarantees the monitoring of past occurrences but SIEM supplies the
intelligence that is ready to be acted upon thus making the detection and
response to security threats quicker. Organizations that use both solutions together
not only gain a security posture that is complete but also one that is
proactive.
