Network Architecture and Design:
The Top-Down Approach

Network architecture and design are many times two separate stages in a network implementation project. McCabe (2007) identifies network architecture as a higher level concept of a network. He says that it focuses on more general relationships between the major components of a network. For example, "addressing and routing, network management, performance, and security." (p. 211). The design stage of the project normally starts after the higher level architectural plan has been approved. This is where the real detailed work starts and the nuts and bolts start to come together.

Intrusion detection and prevention systems are the most reliable form of securing APT incidences and the overall security of the information infrastructure. This is because, unlike susceptibility and management systems and IT infrastructure support, they have the capacity to detect occurrences of APT and subsequently prevent damage to the computer systems. Firewalls are supposed to block illicit impound traffic, but in most instances, they do not succeed. Intrusion detection and prevention systems have the capability to detect and catch threats missed by the firewalls. Susceptibility management systems are used to identify, remediate and mitigate vulnerabilities in computer networks but Continue reading...
