A short history of a big evolution and how to maximize the benefits of your security options
Security Event Management (SEM) tools were designed for threat management against a noisy external threat environment that consisted primarily of worms. SEM tools focused mainly on network and system events combined with real-time analysis to support incident response. Security Information Management (SIM) provides long-term storage of log files, historical analysis and trending against large databases of data to support forensic activities. IT professionals could purchase a SEM tool for real time analysis to support incident response and a separate SIM tool for long term storage and historical analysis to support trend reporting and forensics.
Security information and event management (SIEM) is an approach to security management that seeks to provide a holistic view of an organization’s information technology (IT) security. SIEM combines SIM (security information management) and SEM (security event management) functions into one security management system. By bringing these two functions together, SIEM systems provide quicker identification, analysis and recovery of security events. They also allow compliance managers to confirm they are fulfilling an organization’s legal compliance requirements. A SIEM system collects logs and other security-related documentation for analysis. The collectors forward events to a centralized management console, which performs inspections and flags anomalies. To allow the system to identify anomalous events, it’s important that the SIEM administrator first creates a profile of the system under normal event conditions.
SIEM systems are typically expensive to deploy and complex to operate and manage. Costs associated with a traditional SIEM deployment include: initial licensing costs, implementation/optimization costs, ongoing management costs, integration of data sources from disparate security technologies, training of personnel/incoming personnel. While PCI compliance has traditionally driven SIEM adoption in large enterprises, concerns over advanced persistent threats (APTs) have led smaller organizations to look at the benefits a SIEM managed security service provider can offer. SIEM’s are now widely used by many organizations to ensure that the systems, applications, and data an organization relies upon are always available, performing well, and are secure.
