SIEM Buyer's Guide
What is Security Information and Event Management (SIEM)?
Security Information and Event Management (SIEM) is an approach to security management that combines security information management (SIM) and security event management (SEM) functions into one security management system. The foundational principle of SIEM is the aggregation of data that is relevant to an organization from multiple sources. Certain organizations will leverage a SIEM solution to stop abnormalities and associate an action. Sophisticated organizations will leverage correlated data in conjunction with user and entity behavior analytics (UEBA) or security orchestration and automated response (SOAR).
How to Evaluate a SIEM Solution
SIEM solutions have become an integral piece of IT and Security operations. When looking to onboard a SIEM solution, consider the following:
Threat Intelligence Feeds
Does the solution push or pull from the feeds needed to maintain or improve an organization’s security posture?
When capturing events, can the solution capture the appropriate information to arm investigations?
Can the solution work towards triage and remediation by pushing or pulling actions to or from other solutions?
Artificial Intelligence / Machine Learning
Leveraging the continuous data set, can the solution improve on accuracy through unsupervised or supervised machine learning?
Can the solution provide the organization with the needed regulatory compliance standard reports?
