Using Modern System Engineering Methods for Resilient Cyber Design and Test
Modern military and civilian systems of systems, have seen a great increase recently in Cybersecurity vulnerability. This increase, threatens infrastructure, safety, compromises security, causes damage to internal and external information systems, can have considerable cost impact including direct loss of critical funds as well as intellectual property. The damage that these data breaches can be severe and have cascading effects to the normal operations of military and civilian systems. In response to this vile threat, the US Government and civilian entities have responded with new defensive processes and software to combat cyber threats. To be more successful, a modern systems approach must be employed throughout the enterprise and throughout the lifecycle of vulnerable systems. Cyber resiliency must be inherent in the design and enterprise processes. It is much more efficient to stop the cyber threat early and to try to pick up the pieces after a serious breach. Cybersecurity is now becoming a fundamental part of the system engineering process and should be incorporated through all phases of the life-cycle process.
This paper will examine using advanced system engineering methods, such as Model Based System Engineering (MBSE), to encapsulate cybersecurity governance, defining cyber requirements, examine some examples of cyber resilient design and highlight the testing and monitoring of modern enterprise systems using the MagicDraw UML tool set with SysML and DoDAF profiles.
