Today, antivirus programs can no longer keep you protected from online threats that have breached millions of systems across the globe. Cybersecurity companies exist to protect businesses and organizations that are looking to fortify themselves against cyber-attacks. The best way to do this is by deploying a SIEM. However, this can come with various challenges and complexities, which require the attention of experienced cybersecurity companies.
If you want to protect your company against online threats, you have to make sure that you optimize your SIEM tool. In this blog, we’re going to go over five key ways to tune your SIEM. Here are what cybersecurity companies recommend.
Deploy Your Solution Steadily
An all-at-once approach to deploying your SIEM could lead to technical issues and an overwhelmed IT team. This solution works best when paired with other cybersecurity solutions. These solutions include endpoint security, but sometimes integration issues can come up. These issues can become overwhelming when your team is trying to learn new solutions while also attempting to juggle incoming security alerts and threat intelligence feeds.
The best way to avoid integration issues is to deploy your SIEM on the most critical network areas as and sensitive databases.
Optimize SIEM Rule Sets
It’s essential to perform regular auditing and maintenance over your solution’s correlation rules. This ensures that your cybersecurity solution recognizes suspicious activity and can distinguish between said suspicious activities and healthy behaviors.
SIEM works through machine learning and correlation rules, and this takes a massive load off your IT team’s shoulders.
This method ties into the rule sets, but it’s important to improve your solution’s contextualization. Contextualization makes it possible for your SIEM solution to distinguish between normal behaviors and suspicious activities. Contextualization reduces the false positives rate.
Don’t Stop the Deployment Process
As we mentioned in the first point, you should take the deployment stage slowly to avoid deployment issues. However, you need to make sure that you deploy your SIEM solution across your entire network. Cybercriminals are always looking for ways to get into your system; it’s vital to cover all your bases.
Make Sure Your Company is Capable
You need to focus on more than just the solution’s capabilities. To properly optimize your SIEM, you need to examine your companies’ capabilities. This includes matching your log storage capacity with your business needs. Your storage should be capable of handling at the very minimum a month or two of security data at a time for full correlation and analysis.
SIEM optimization is crucial in protecting your company from the online threats you’ll come across today. If you’re looking to deploy a SIEM across your network, make sure that you look into hiring professionals to help you through the complicated process that is cybersecurity.
