(IA) Engineering is about developing computer
networks, wired and wireless communication systems to remain
dependable in the face of malice, error, and mischance. As a
discipline, IA Engineering focuses on tools, processes, and methods needed
to design, implement, and test systems and to adapt existing
systems to survive in a hostile environment.
IA methodologies ensure all security requirements are met by
integrating them during the systems development life cycle (SDLC).
