What is SIEM?A security information and event management (SIEM) solution is aimed to collect all information across your business, standardize it to make it accessible, analyze it for irregularities, and then monitor events and remediate issues to keep intruders out. SIEM is an integral part of a security stack, your very own looking glass into the state and health of your infrastructure. SIEM solutions provide real-time analysis, monitoring, and alerting. By bringing in logs from your system’s different components, they create security information to analyze and act upon. Suggested Reading: EDR vs SIEM: Which Threat Detection Tools You Need?
Why is SIEM important, and how does it work?SIEM collects event information across an organization’s network. The log data is captured from the users, apps, resources, data centers, and networks. SIEM software generates warnings for an organization’s security personnel when it detects a risk, breach, threat, or unusual behavior. SIEM plays a vital role in compliance as most standards like the PCI DSS, GDPR, and HIPAA require the collecting and reporting log data. The growing emphasis on compliance and keeping businesses secure has made SIEM solutions more valuable to small and medium enterprises. Insider Threats pose a considerable risk to every organization. SIEM enables the managing and monitoring of user access and events. They quickly alert about irregularities identified by processing and analyzing log data. SIEM normalizes the data collected from various sources to provide easy-to-understand visualizations which provide crucial information about the health of your infrastructure. This provides the ability to investigate any irregularities in your environment.
