The Security Information and Event Management (SIEM) technology is involved in threat detection and security incident response through the analysis of security events obtained from a variety of events and sources of data. SIEM combines SIM (Security Information Management) and SEM (Security Event Management) functions into one security system. Upon detecting an issue, it often works by logging additional information, raising an alert and instructing other security controls to stop an activity.
Security Information and Event Management (SIEM) and Security Operations Center (SOC) offer a wide array of comprehensive and powerful analytical skills to increase security controls for an organisation and ward off existing threats and risks at the same time. SOC is a set of tools and techniques to respond to and prevent cyber-attacks.
Splunk Enterprise Security (ES) is a product that specialises in SIEM and collects data from a wide variety of sources like security controls, operating systems and applications for further study and analysis. This helps in identifying activities that violate security policies. Thus, by identifying security issues with the help of Splunk ES, it becomes easy to ward off attacks and malicious activities.
