What is a SIEM Tool?

A SIEM Tool is a Security Information and Event Management tool which combines Log Management, Security Log/Event Management, Security Information Management and Security Event correlation into one platform. By combining these elements together SIEM tools provide a comprehensive way to manage security threats within enterprise grade networks.

SIEM tools are comprised of two main tool types; Security Information Management (SIM) and Security Event Management (SEM) solutions. SIM tools pull data from log files to produce reports on security incidents and SEM tools monitor for real-time events and raise notifications. When put together, these tools produce the SIEM experience that has become popular amongst modern enterprise users.

How SIEM Tools Work

SIEM tools are designed to collect log data from elements throughout your network. From this log data, the SIEM tool can identify security events and analyze them to help you find the root cause. More specifically, SIEM tools provide the user with:

  • Reports and additional details about security incidents
  • Alerts highlighting when a security event has taken place

In other words, SIEM tools work by providing you with the information you need to respond to security incidents more promptly and effectively. Rather than responding to security events manually, you can act as soon as an alert has been sent to you based on log data provided to you by the SIEM tool.

Why do I need a SIEM tool?

Staying protected against modern security threats is next to impossible without the right tools. If you don’t have complete visibility over your log data then you’re bound to miss something important. Missing the signs of an attack could potentially cost thousands in downtime. A SIEM tool can avoid this happening by providing you with access to your log data and notifications about security incidents.

Having a SIEM tool is also very pragmatic on behalf of your network administrator as it eliminates the need to manually monitor log data. Once a SIEM tool automates much of your log management activities, your network administrator has lots of time to focus on other important tasks.

Another very important reason comes in the form of security compliance. In many industries, SIEM tools are required to ensure regulatory compliance.
