Answer: B
Identification of the applications required across the
network should be identified first. After identification,
depending on the physical location of these applications in
the network and the network model, the person in-charge will
be able to understand the need and possible ways of
controlling access to these applications. Identifying
methods to protect against identified vulnerabilities and
their comparative cost-benefit analysis is the third step.
Having identified the applications, the next step is to
identify vulnerabilities (weaknesses) associated with the
network applications. The next step is to analyze the
application traffic and create a matrix showing how each
type of traffic will be protected.
