43% of cyber attacks target small businesses. 60% of these companies go out of business within six months following the attack. This frightening statistic is why you need to build your defenses with SIEM. In this blog post, learn more about what is SIEM, and how can you implement it to protect your small business.
When a cyber-attack happens to you, it feels like a kick in the teeth.
What Is SIEM?
SIEM means Security Information and Event Management. It allows you to view your network as a whole rather than just the sum of its parts.
SIEM combines security data from different sources, identifies what’s wrong, and prevents problems from happening or from getting worse.

How Does SIEM Work?
SIEM uses a multilayered approach to secure your online assets. Here’s how:
- SIEM detects potential threats throughout your entire network, including firewalls, WiFi networks, devices, and more.
- SIEM will alert you to real-time threats, which allows you to fix any potential breaches before they become big problems.
- SIEM makes your data easier to manage; it simplifies the log information to help you invest your time to fix the treats instead of needing to translate mountains of log data.
How Do You Implement SIEM to Protect Your Business?
Unfortunately, SIEM is not something you can just set and forget. The effectiveness of your SIEM depends on how you set it up, maintain, and continuously monitor.
You need to give it the right context to get it to track your network activity. This context comes in the form of:
- What that activity is?
- Where it’s coming from?
- What it should look like?
Knowing the context allows the SIEM to tell the difference between real attacks and false positives.
You will need to have a standard message format, so when the SIEM sees logs from separate assets, the system will correctly understand the information in these logs. Once your log files are communicating in the same language, you can put the data into a database table.
This database table will let you track and monitor specific events across your assets. You can also report and create an automated correlation of events. You can match fields from log events and sort them by different times and different devices.
Implementing SIEM Takes Time and Tweaking, but It Can Stop Catastrophes Before They Start.
Once you get your SIEM up and running, your business will be far more protected. SIEM will help you detect attacks in real-time and block them before they do any real damage.
Setting up SIEM for your business may seem daunting. However, if you start setting one up today, you can breathe easier tomorrow. Contact us.
