Security Onion is a comprehensive solution for network security and intrusion detection, built on a Linux distribution. It includes a wide range of tools and technologies designed for continuous monitoring of network traffic, log analysis, and response to potential threats.
One of the key features of Security Onion is its ability to provide real-time traffic analysis through integration with powerful tools such as Snort, Suricata, and Zeek. These tools enable instant detection of anomalous or malicious activities on the network.
Additionally, Security Onion offers centralized storage and log analysis capabilities using the popular ELK stack (Elasticsearch, Logstash, Kibana). This allows for quick and efficient searching, analyzing, and visualizing of data from various sources, greatly facilitating the detection and response to potential security threats.
With its flexibility and scalability, Security Onion can be successfully deployed in both small office environments and large corporate networks. It provides a powerful toolkit for network security and intrusion detection, making it a vital component in the information security arsenal for organizations of any size.
Warning
Attention! After creating the virtual machine, a process for generating product settings will automatically start. On average, this takes 40-50 minutes, depending on the parameters of the virtual machine. This is done to provide a complete and secure product.
- Obtain a pair of SSH keys for connecting to the virtual machine (VM).
- Create a VM from a public image. In the Image/Boot Disk Selection block, go to the Cloud Marketplace tab and select SecurityOnion. In the Access block:
- Enter the username in the Login field;
- Paste the content of the public SSH key file in the SSH Key field.
Warning
You can monitor the installation process either via the “Serial Port” or by connecting via SSH and checking the /var/log/messages file.
-
Connect to the VM via SSH.
-
Elevate privileges to
root:sudo su -
Retrieve the administrator password from the
so-admin-passwordfile:cat /root/so-admin-password -
Copy the password. You will need it to access the web interface.
-
In your browser, go to
https://<public_IP_address_of_VM>/. -
To connect to the service, use the following credentials:
- Username —
soadmin@so.local. - Password —
<password_from_root_password_file>.
Change the password if necessary.
