What Is SIEM Software? (+The Best Tools for Your Business)

July 23, 2019

If you could stop something detrimental from happening before it happened, would you?

Maybe detrimental is too strong of a word. But if you could predict something like a cyber security breach or a hacker infiltrating the cloud, from happening within your company, I bet you’d answer with a resounding yes.

That’s what Security Information and Event Management, SIEM for short, software can do for your company. Interested in learning what this innovative tool can do to stop an attack before it happens and save your company both time and money? Just keep reading.

What is SIEM?

Before we jump right into the benefits of using SIEM, first let’s define it.

Essentially, SIEM is comprised of two tools in one.

  1. Security Information Management (SIM): Software that automates the collection of data from log files in order to analyze and report on security threats and events
  2. Security Event Management (SEM): Software the conducts real-time system monitoring, notifies network admins about any potential issues, and forms a correlation between security events.

How SIEM works

SIEM software works by collecting data throughout an organization's infrastructure and storing it on a centralized platform.

This data is comprised of network devices, servers, domain controllers, and more. SIEM then stores, analyzes, and aggregates analytics to this data as it works to discover trends, detect threats, and investigate any alerts.

For example, when a potential issue is detected, the SIEM will log additional information, generate the alert, and instruct security controls to stop the progress of the threat.

Anything from antivirus events to firewall logs are collected, identified, and stored into categories, such as malware, attempted and failed logins, or other malicious activity.

How does SIEM work?
At its core, SIEM is a data aggregator, in addition to a search and reporting system. The extensive data it gathers from your networked environment is consolidated and made accessible and able to be understood in real-time.

Benefits of using SIEM

If your company is looking to centralize security operations into a single location, then utilizing SIEM is the next logical step. As a powerful tool for threat detection, real-time reporting, and heightened information on security logs and events, SIEM has many benefits, including:

  • Preventing potential security threats
  • Increasing efficiency
  • Reducing the impact on security breaches
  • IT compliance
  • Reducing the cost of a security breach
  • Advanced reporting, retention, and log analysis

Since SIEM tools collect event logs from varying applications and devices, they allow your IT staff to identify, review, and respond to these threats faster. When you are given the right tools to pinpoint these threats sooner, it saves your company time and money, while also making sure the threat has a minor impact, if any at all.

The future of SIEM tools hold a lot of exciting possibilities and potential, as machine learning, advanced statistical analysis, artificial intelligence, deep learning, and other analytic methods become more advanced and provide more information about security threats than ever before.
