As companies deploy network applications and information systems, concepts of operations, techniques and procedures must be implemented to protect their infrastructure, applications, data, and the users. TVAP can help design solutions that can easily integrate existing infrastructure, preserve performance and increase reliability using easy to manage techniques. TVAP has identified the most effective security architectures are those based on efficient multiple layers where each layer supports the protection of the others. Layers are required to be designed to complement functionality, interoperability and hides network defenses.
