24/7 DETECTION – ANALYSIS – RESPONSE
A SIEM is a Security Information Event Management system that collects and aggregates outputs from multiple log sources in order to provide better visibility into an organization’s security posture. The SIEM allows the security engineer to cross-correlate events from critical log sources (e.g. firewalls, servers, switches, etc.) to detect threats and decrease the amount of time a malicious adversary may be in/on a network.
For today’s resource-strapped IT departments, the time and expense required to deploy a SIEM seriously delays their their time to threat detection.
