Irish based Exigent Networks has produced the following Infographics on Building a Network Infrastructure. The graphic outlines the steps that need to be taken in building a network infrastructure, detailing each part of the process, while also advising as to the benefits of having a quality network infrastructure in place, and provides security tips.
Considering all the security requirements at the design stage is far cheaper, and indeed results in a more secure network infrastructure, as opposed to trying to bolt on security to a poorly designed network. Also remember keeping the network infrastructure secure is an ongoing process, vulnerability testing, patching systems and devices, including switches, firewalls and routers, requires a continued process.
