You can deploy it on the cloud (yes, even on AWS) or on-premises. If you choose the cloud, simply spin up an instance and you’re good to go. Remember, deploying on the cloud can offer benefits like an auto-scaling policy, making your life easier.

Step 2: Integrating Vulnerability Scanner

Now, let’s integrate a vulnerability scanner. Think of it as a digital detective that’s constantly on the lookout for any weaknesses in your system. We’re going to use Nessus, a popular choice, and link it with Elk Stack. VulnWhisperer, which you can find on GitHub, will pull data from Nessus and send it to Elk Stack. This is where the magic happens!

Step 3: Configuration for SIEM

Elk SIEM (Security Information and Event Management) comes into play now. This is where Elk Stack truly shines as a management tool. Set up your configuration files to define what data to collect and how to process it. Logstash, a component of Elk Stack, can break down and filter your data. It’s like having a smart assistant who can sort out what’s important and what’s not. You can even add fields or drop fields that are not required to cover your specific needs.

Configuring and Running Vulnerability Scans with Elk Stack

Once you’ve set up Elk Stack, it’s time to configure and run your vulnerability scans.

• ✅ Connecting the Scanner to Elk Stack: Link your scanner (in our case, Nessus) with Elk Stack. Use the API to ensure a seamless connection. This step is like creating a direct line of communication between your detective (the scanner) and your analyst (Elk Stack).
