How SIEM Works
A SIEM has two closely related purposes: to collect, store, analyze, investigate and report on logs and other data for incident response, forensics, and regulatory compliance purposes; and to analyze the event data it ingests in real time to facilitate the early detection of targeted attacks, advanced threats, and data breaches.
SIEM software works by ingesting and interpreting all that data and incorporating threat intelligence and advanced analytics to correlate events that could signal a cyberattack is underway. The system then alerts security teams of the threat. It suggests responses to mitigate the attack, such as shutting down access to data or machines and applying a missing patch or update.
An example of correlation might be to connect a port scan with access to sensitive data, perhaps in multiple locations, thus adding context to what might otherwise seem to be unrelated events.
Why is SIEM Important?
To get an idea of how vital a SIEM is, consider the scale of the security incidents and data involved. A large enterprise may generate more than 25,000 events per second (EPS) and require 50 TB or more of data storage.
A SIEM’s ability to filter through all the data and prioritize the most critical security issues makes security more manageable. An effective SIEM tool will pay for itself in staff time saved, even as the system itself requires management and tuning.
How to Choose a SIEM
SIEM tools are differentiated by cost, features, and ease of use. Generally, the more you pay, the greater the capabilities and range of coverage, so buyers must weigh their needs, budget, and expertise as they decide on a SIEM system.
Small businesses might focus on automation, ease of use, and cost. In contrast, an enterprise with a sophisticated security operations center (SOC) might focus on the breadth of threats and assets covered and machine learning capabilities for discovering new and emerging threats. Regardless of an organization’s size, deploying and integrating such a complex technology can take time, so the help of consultants and services firms is often needed.
Despite its relative maturity, the growth of the SIEM market remains strong. A significant trend is the growing use of behavioral analytics, automation, and cognitive computing to filter out less urgent alerts so security teams can focus on the most significant threats, with advanced UEBA and SOAR capabilities becoming increasingly common.
Analysts see the cloud as a growing means of delivery for SIEM services, both for SMBs and for hybrid organizations seeking more manageable ways to keep track of their complex environments.
