Security Incident and Event Management helps organizations detect and handle security threats, but what exactly is the principle behind it? And why is it relevant for Businesses?
Combining Security Information Management with Security event Management, The principle behind SEIM’s is to collect relevant data from sources, identify abnormal deviations and take actions appropriately. For example, when a potential issue is detected, a SIEM system might log additional information, generate an alert and instruct other security controls to stop an activity’s progress.
SIEM adoption in large enterprises was originally driven by Payment Card Data Security Card Compliance (PCI DSS). However, growing concerns over advanced persistent threats have spurred on to smaller organizations.
Most SIEM systems work by deploying collection agents to gather security related events from end user devices, servers and network equipment. The collectors’ forward events to a Centralized Management Console where security analysts sift through the noise, connect the dots and prioritize security incidents.
Being able to look at all security data from a single point of view makes it easier for organizations to spot patterns that are out of the ordinary. When evaluating SIEM products, organizations should consider:
- Integration with other controls.
- Artificial Intelligence and accuracy.
- Threat intelligence feed compatibility.
- Compliance report resources.
- Forensics capabilities.
In terms of the overall importance, SIEM’s are great to gain visibility into threats, they provide an attack chain that would identify various hosts that might have come into contact with malicious activities going on in the network.
SIEM’s also give faster detection and response capabilities that provide more efficient security operations because there is a platform that’s directing remediation and investigation activities.
