The other bisections relate to systems that can serve multiple duties and may act upon systems outside the virtual environment as well as within the virtual environment. It is also interesting to note that you may have multiple IDS/IPS systems involved in that particular aspect of security. An event, in this case, also includes natural disasters, fire, and power outage. The purpose of information security is to protect data against any threats. Note that when a virtualization host crashes, all the virtual machines running within the virtualization host crash. The demarcation bisects the IDS/IPS Server, among others, and that is on purpose, because you need to understand that a physical IDS/IPS may not work within the environment unless it is placed appropriately on an interface into the virtual infrastructure. For many people, today’s world is an insecure place, full of threats on many fronts. When we look at just the data center, the following steps are usually taken: Securing the datacenter entails the use of physical controls and monitoring tools to monitor access (card keys, video camera), power provisioning and control, cooling, and change control protocols. The threat is not a security problem that exists in an implementation or organization. Included in this is the possibility of intrusion detection and prevention systems, virtual machine vulnerability management tools, or even virtual network compliancy auditing tools.
