Let’s more closely examine the biomedical company mentioned in the last bullet point above. This company is heavily invested in its intellectual property, and has identified that the greatest threat to its organization’s survivability is the loss of that intellectual property. Considering that, the following questions, could be asked: • • • • • • • What devices generate raw research data, and how does that data traverse the network? From what devices do employees process raw research data? On what devices is processed research data stored?
That means that collection should feed detection, detection should feed analysis, and analysis should feed back into collection. This allows the defender to build intelligence over time that may be used to better serve the defense of the network. Threat-Centric Defense. All of the characteristics I’ve discussed thus far have led to the concept of threat-centric defense. Whereas vulnerability-centric defense focuses on the “how”, threat-centric defense focuses on the “who” and “why”. Specifically, you must ask yourself who would be interested in attacking your network, and why would they stand to gain from such an action?
You should also ensure your network interfaces are connected to the virtual machine at this time. 19 20 CHAPTER 1 The Practice of Applied Network Security Monitoring 2. Mount the downloaded ISO as a virtual CD/DVD drive in your virtualization software. 3. When you start the VM, allow it to boot to fully into the live operating system. Once this process completes, select the “Install SecurityOnion” icon on the desktop to begin installing the operating system to the virtual disk. 4. Follow the prompts presented to you by the XUbuntu installer.
