Computer network security is concerned with safeguards, responses and controls to prevent, react and respond to attacks perceived on valued information assets. Unfortunately, current technical controls use by enterprises to protect their IT investments are often stand-alone systems whose independent protection are either isolated or localised, and insufficient in adequately protecting these assets.
This book discusses an approach to security defence that combines and integrates the defences offered by stand-alone countermeasure systems to adequately detect widespread attacks. An integrated...

This introductory text teaches foundational concepts in numerical mathematics. It uses real-world examples, representational graphs, solved tutorials, practice problems, flow diagrams, algorithms and computer programs to enrich knowledge and strengthen understanding. It covers contemporary numerical method techniques, such as root finding methods, difference calculus and interpolation principle. It explains existing traditional techniques used in solving engineering and process-based tasks involving numerical differentiation and integration, such as Eulers method, rectangular...
