When managing a whole database and network, you need to have someone that can deal with issues and fix problems a system may face. This is where engineers come in. The role of an engineer can vary. First, a security engineer comes in and is responsible for testing and screening security software and for monitoring a network and system for any security breach or intrusion. Engineers are responsible for the up keeping of a server and ensuring that a possible threat can be countered and dealt with. A systems engineer just monitors existing systems to ensure structural integrity and oversee’s the development and installation of new hardware and software.

So the principles of security and engineering, these are what guidelines an engineer should follow when managing a security system. Ensuring the up keep of a server along with making sure that everything works the way it should in the case an attack happens. Maintaining the security triad of confidentiality, integrity, and availability.
