Overview of this book

Most enterprises use Cisco networking equipment to design and implement their networks. However, some networks outperform networks in other enterprises in terms of performance and meeting new business demands, because they were designed with a visionary approach. The book starts by describing the various stages in the network lifecycle and covers the plan, build, and operate phases. It covers topics that will help network engineers capture requirements, choose the right technology, design and implement the network, and finally manage and operate the network. It divides the overall network into its constituents depending upon functionality, and describe the technologies used and the design considerations for each functional area. The areas covered include the campus wired network, wireless access network, WAN choices, datacenter technologies, and security technologies. It also discusses the need to identify business-critical applications on the network, and how to prioritize these applications by deploying QoS on the network. Each topic provides the technology choices, and the scenario, involved in choosing each technology, and provides configuration guidelines for configuring and implementing solutions in enterprise networks.

Security landscape

The security threat landscape has changed drastically over the last few years. The earlier forms of security attacks on the IT assets of an organization were in the form of viruses and worms. Over the years, we have seen blended attacks that use a mix of multiple technologies to attack the victim. There has been an increase in advanced persistent attacks, and targeted attacks that are written specifically for a particular organization. The use of social engineering coupled with the malware that changes forms over time and on different operating systems has made the detection of attacks difficult.

The security landscape has become even more complex because of the increase in the number of devices, some of which are not even organization controlled because of the Bring Your Own Device (BYOD) policy in some organizations. The diminishing boundaries of enterprise...
