Security Onion is a free and open sourceintrusion detection system , security monitoring, and log management solution. I figured one of the best ways to do this is set up a sever running security onion. I forget what the specs are but it has windows xp on it.

Setting up Security Onion at home

Security Onion includes a native web interface with built-in tools analysts use to respond to alerts, hunt for evil, catalog evidence into cases, monitor grid performance, and much more. Additionally, third-party tools, such as Elasticsearch, Logstash, Kibana, Suricata, Zeek , Wazuh, Stenographer, CyberChef, NetworkMiner, and many more are included. Many folks have asked for a printed version of our official online documentation and we're excited to provide that! Whether you work on airgap networks or simply want a portable reference that doesn't require an Internet connection or batteries, this is what you've been asking for. If nothing else, spinning up a test deployment of Security Onion is a great way to have something to benchmark against when evaluating those six-figure-per-seat-per-year solutions. Security Onion is under active development, and their public roadmap includes a move away from Debian package deployment to using Docker to support RHEL/CentOS systems more easily.

If you have a distributed deployment, then we recommend monitoring SOC Grid while your update is running to verify that all nodes update properly.

At the end, we should have seen something like this.Now we are pretty much all set up. We can access our Kibana interface and see everything that is coming through our network now. Escalate alerts and logs to Cases and document any observables. Pivot to Hunt to cast a wider net for those observables.

Tips on setting up a security onion server on my home network.

There should be an option to add a standard virtual switch. We give access running the so-allow commandWe see that there are a ton of different options that we can choose from.
