What is a key function of a security information and event management SIEM solution?
What is SIEM?SIEM stands for security, information, and event management. SIEM technology aggregates log data, security alerts, and events into a centralized platform to provide real-time analysis for security monitoring. Show
Security operation centers (SOCs) invest in SIEM software to streamline visibility across their organization’s environments, investigate log data for incident response to cyberattacks and data breaches, and adhere to local and federal compliance mandates. How Does SIEM Work?SIEM software works by collecting log and event data produced from applications, devices, networks, infrastructure, and systems to draw analysis and provide a holistic view of an organization’s information technology (IT). SIEM solutions can reside either in on-premises or cloud environments. Analyzing all of the data in real-time, SIEM solutions use rules and statistical correlations to drive actional insight during forensic investigations. SIEM technology examines all data, sorting threat activity according to its risk level to help security teams identify malicious actors and mitigate cyberattacks quickly. The Evolution of SIEM SoftwareSIEM solutions have been around for over 15 years, but today’s modern SIEMs have evolved from their original counterparts. Mark Nicolett and Amrit Williams established the term “SIEM” in a 2005 Gartner research report, Improve IT Security With Vulnerability Management. [1] These legacy SIEMs were a combination of integrated security methods into one management solution, including:
As SIEM software transformed over time, the core components continue to provide value, but innovative technology within the competitive landscape paved the way for more comprehensive and advanced approaches to reducing risk in an organization. This led SIEM providers to eventually launch new features that have termed these enhanced products as “next-generation SIEM” solutions. Next-Gen SIEM vs. SIEMWhat are the major differences between traditional SIEM solutions and next-gen SIEMs? At the core, both solutions have similar functionality, but legacy SIEMs can’t handle the rising volume and complexity of data in today’s threat landscape. With the increase in cloud adoption, mobile technologies, hybrid datacenters, and remote workforces, next-gen SIEMs are much more suited to meet the growing demand for threat detection and response across disparate systems. Next-gen SIEM solutions provide new capabilities for improving security visibility and threat detection, while also streamlining the process for security teams to manage their workload. Some core components of a next-gen SIEM solution, include:
Benefits of SIEM TechnologyDepending on the solution and vendor, SIEM components can provide a wide variety of benefits that help to increase overall security posture, including:
How to Get the Most of a SIEMFrom small SOC teams to large global IT departments, organizations use SIEM solutions to streamline their threat detection and response to measurably reduce risk to the business. However, many SIEM technologies are resource intensive and require experienced staff to implement and manage or augmented services for support and training. Before investing in SIEM, gather your business requirements and evaluate your security objectives and priorities. It can be an investment up front, but SIEM software helps security teams achieve compliance and mitigate risks quickly, saving the business from significant financial implications and legality issues if a breach were to occur. When choosing a SIEM solution, be sure to understand how licensing models determine the true total cost of ownership (TCO) and take into account future growth as your organization may expand over the years. It’s critical to find a trusted provider that aligns to the needs of your business for long-term scalability, while also helping your team effectively deploy a solution quickly to get the highest return on investment. Here is useful a guide to help you budget for a SIEM and manage financial risk along the way. Interested in watching SIEM in action?

It also delivers operational capabilities such as compliance reporting, incident management, and dashboards that prioritize threat activity.
What are the 3 main roles of a SIEM?Gartner identifies three critical capabilities for SIEM (threat detection, investigation and time to respond) — there are other features and functionality that you commonly see in the SIEM market, including: Basic security monitoring. Advanced threat detection. Forensics & incident response.
What is security information and event management SIEM in software development?A SIEM primarily collects data from servers and network device logs, but is more effective when used to aggregate data from endpoint security, network security devices, applications, cloud services, authentication and authorization systems, and online databases of existing vulnerabilities and threats.
What are the most important reasons to have a SIEM?Why is SIEM important? SIEM is important because it makes it easier for enterprises to manage security by filtering massive amounts of security data and prioritizing the security alerts the software generates. SIEM software enables organizations to detect incidents that may otherwise go undetected.
