The Network Availability Prediction network block diagram model utilizes an extended Reliability Block Diagram (RBD) methodology that addresses the specific characteristics of network elements and their connections.


AttackTree allows threats against system security to be modeled concisely in a graphical format. The effectiveness of internet security, network security, banking system security, installation and personnel security may all be modeled using attack trees. With the increased risk of terrorist attacks on homeland security, hacking attacks on computer systems and computer-based fraud on banking systems, AttackTree is an invaluable tool to system designers and security personnel.
