IT security engineering

IT security engineering is the application of security principles to information technology. In our modern world, this really can mean just about anything, from a server to a refrigerator, once you start to consider the Internet of Things (IoT). There are so many new devices being built daily that are IP addressable, essentially making them mini-servers, which introduces potential vulnerabilities. Additionally, it is important to consider the security needs for devices that are non-networked or may be air gapped. Nonnetworked, or air-gapped, environments still have the capability to communicate through out-of-band means, such as a USB thumb drive, allowing an attacker to communicate with them. A mature organization should have staff specifically targeted at looking at information technology security concerns, working with business and information technology leadership to secure IT systems and protect the environment from attackers.
