Network security for a communications company

Abstract

XYZ Communications (XYZ Communications is a pseudonym for the company's actual name) is a wireless communications company specializing in two-way radio frequency such as cellular and paging systems and is based in the Midwest. Electronic messages are sent throughout the United States via phone, email or http requests. XYZ Communications uses the Internet and Plain Old Telephone System extensively as a transport for their paging and technical support systems. Due to the company’s connection with networks outside of their own Local Area Network, XYZ Communications understands the need for security and has taken some measures to secure their current network infrastructure. However, even with this understanding and their current security measures, XYZ has recently become the victim of multiple network attacks. In light of these new attacks, XYZ Communications would like to reexamine their current network with the intent of making it more secure from intruders. This research paper will analyze the current network infrastructure and provide suggestions for improving network security on the network's perimeter. The study was conducted by reviewing relevant literature, analyzing the network infrastructure and providing suggestions for improving security.
