Security Engineering is concerns with how to develop and maintain systems that can resist malicious attacks intended to damage a computer-based system or its data. Security engineering is a specialized field of engineering that focuses on the security aspects in the design of systems that need to be able to deal robustly with possible sources of disruption, ranging from natural disasters to malicious acts. It is similar to other systems engineering activities in that its primary motivation is to support the delivery of engineering solutions that satisfy pre-defined functional and user requirements, but with the added dimension of preventing misuse and malicious behavior. These constraints and restrictions are often asserted as a security policy. Facile Architectural design provides the robust solution to the security of the system. Facile always focus on good practice when design the secure systems. Facile works on the support to be required into a system to avoid the introduction of vulnerabilities when a system deployed for use. Risk Management is the key area Facile is always focus like Preliminary risk assessment, Life Cycle Risk Assessment and Operational Risk Management.
