Important SIEM Features

Although SIEM systems aren’t without fault, they’re one of the biggest tells that a firm takes cybersecurity seriously and that they’ve chosen to implement a good policy. 90% of the time, you’ll find that attacks on your network don’t have any surface-level hints. Because of this, it’s often better to use log file data to spot these. This naturally leads to SIEM tools becoming one of the pillars of network security.

You’ll find that a lot of security-oriented applications work on small-scale issues. While they’ll often solve more minor threats, they’ll also miss the bigger picture. A simple IDS (Intrusion Detection System) by itself can only really keep track of packets coming in and out, as well as IP addresses. Similarly, you’ll find that service logs will only display user sessions and changes to any configs. SIEM takes these simple systems and puts them together to give you a much better look at any security issue by providing real-time monitoring and analyzing all event logs.

What Is SIM?

SIM, or Security Information management, also known as log management, refers to the collecting, monitoring, and analyzing data provided by the computer logs.

What Is SEM?

SEM or Security Event Management refers to managing network events. This includes a variety of security processes, such as threat visualization and real-time analysis.

What Makes SIEM Important?

SIEM has started to take a more prominent place in most modern businesses’ cybersecurity throughout the last few years. The biggest reason for this is that all trackers and users leave behind a virtual trail in the log data. SIEM tools take advantage of this data to analyze attacks and other network events. Having a SIEM system will let you know when an attack occurred and how you were attacked and what caused it to be possible.

Most enterprises constantly update and upscaling their IT infrastructure, making SIEM more and more critical. Although it’s a common belief that firewalls and antiviruses are often enough to give total protection to a network, zero-day attacks are still quite common when you rely on these measures alone.

SIEM tools solve this problem by precisely detecting suspicious activity compared to past network behavior. This gives SIEM the capability of distinguishing between regular network use and an attack.

Using SIEM will also aid you in complying with various cyber management regulations, becoming increasingly common across many industries. SIEM tools give you the best way to satisfy regulatory requirements and provide you with log transparency you can use to gain a better insight into your security and improve it.

What Does A SIEM Tool Need?

SIEM tools are quite different from each other. Because of this, no SIEM tool is ideal for all businesses. A SIEM tool that is a perfect fit for one enterprise might be found lacking at another. However, there are some key features that SIEM tools will need to qualify for this list.

The Ability To Manage Log Data

With log data management becoming increasingly important for enterprises, no SIEM tool is complete without it. You’ll need your tool to collect log data from many different data sources using additional recording and categorization methods. When you’re deciding on which SIEM tool to use, you should go for the one that can normalize your data well. With that being said, if you find one that you love in all aspects but this one, you can rely on some third-party tools to help you manage log data.

When your data is normalized, the tool will then quantify it and contrast it to the previously recorded information. The tool will then take advantage of this to find patterns within malicious behaviors and alert you to react to them. Your analysts can also make different criteria in most tools for you to be even more prepared for future threats.

Quality Compliance Reporting Capabilities

If you’ve got a SIEM tool that has excellent compliance reporting capabilities, that’ll be a massive convenience for your enterprise. Most good SIEM tools will have a report generating functionality to aid you with conforming to different regulations.

The source of the requirements you want to comply with will be a significant factor in selecting the ideal SIEM tool for you. There are many standards these days, ranging from HIPAA to PCI, NERC, DSS, and many others. If your SIEM tools can help you meet them, that will save you valuable time.

Threat Intelligence Quality

If malicious behavior occurs on your network, you’ll want your SIEM tool to give you a detailed report on how it happened. This data can aid you in refining the internal workings of your network to eliminate the chances of that attack repeating. If a SIEM tool doesn’t help your enterprise prevent future threats, you should look for a different one.

Customizable Alert Conditions

What looks like regular network activity on one network might look like malicious activity on another. Setting criteria for your SIEM tool’s alerts is crucial for getting the most out of its threat intelligence. The more you can customize your SIEM tool’s alert conditions, the more it’ll be able to help you deal with brand new threats. Cyber-attacks are evolving daily, so you should be using a SIEM tool that’s capable of matching their pace.

Furthermore, you’ll want a tool that will let you restrict the number of alerts you get simultaneously. If you’re overflowing with different alerts, your cybersecurity team will be a lot less efficient in dealing with issues. If you’re unable to change alert conditions, you’re setting yourself up to dealing with waves of barely relevant alerts.

Intuitive Dashboard

Now, a SIEM might have excellent functionalities, but if they’re gated behind an unintuitive and difficult to use dashboard, that’ll lead to you wasting valuable time navigating through it. Furthermore, a good dashboard helps you have a much easier time finding threats.
A well-visualized dashboard lets a good analyst detect malicious behavior from a mile away.

What Are The Best SIEM Tools For You?

Before you pick your SIEM tool, you should do a breakdown of what you’re looking to accomplish using it. If you’re looking to get a SIEM tool mainly to help you meet regulations, then you’ll be evaluating report generation much higher than you will the tool’s alert system.

On the other hand, if your primary plan with getting a SIEM tool is to help you protect your enterprise from malicious behavior, you’ll need a tool with excellent normalization and customizable threat detection.

Since there are so many criteria you could be looking at when picking a SIEM tool, we chose to stick to some of the most important ones in this list. We evaluated the SIEM tools below based on the following:

  • How good they are at gathering log messages as well as live data from traffic
  • The quality of its log file management capabilities
  • The data analysis utilities that the tool comes with
  • Whether or not the tool provides quality report generation
  • How easy the tool is to use and install
  • Whether or not there’s a trial period for you to get used to the tool
  • How much value it provides with its price
