About SIEM:
Incorporating security information and event management (SIEM) software into a company’s information technology system gives corporate security professionals insight into and a record of the actions taking place inside their IT environment.
It’s been more than a decade since SIEM technology first appeared, and it started off as a subset of the log management discipline in the beginning of that time. It was decided to combine security event management (SEM), which analyses log and event data in real time to enable threat monitoring and event correlation, as well as incident response, with security information management (SIM), which collects, analyses, and reports on log data – to create a comprehensive security event management solution.
IT infrastructure, from host systems and applications to network and security devices such as firewalls and antivirus filters, can generate a lot of log data. Security information and event management (SIEM) software collects and consolidates log data generated throughout an organization’s technological infrastructure.
A consequence of this is that the programs detect occurrences and events, categorizes them, and then conducts studies on them. Specifically, the process achieves two key objectives, which are as follows: to
Security-related incidents and events such as successful and unsuccessful logins, malware activity, and other potentially dangerous actions are reported, and warnings are sent if an activity runs in contravention of established rulesets and as a result signals the discovery of a potential security flaw.
Most early adopters of compliance management systems were motivated by a need for greater compliance management, according to Paula Musich, research director at Enterprise Management Associates (EMA), a market research and consulting firm situated in Boulder, Colorado.
Auditors required a method of determining whether compliance was being met, and SIEM provided the monitoring and reporting required to meet mandates such as the Health Insurance Portability and Accountability Act, the Sarbanes–Oxley Act, and the Payment Card Industry Data Security Standard, to name a few examples.
The expansion of the SIEM market, however, has been attributed to rising organizational need for more severe security measures, according to industry experts, who have predicted that the market would continue to expand.
