From the Paper:

"More than likely, a personal user will go with the company used by their provider. For instance, the local telephone company as it has grown, it has adopted a network firewall made up of Cisco hardware (machines) and software to provide better protection for its users. Network firewalls have long been an asset to the large corporation as it acts as security for protection of that company's information and intellectual property (Desmond, 2004, p. 1). This is very important as Internet user statistics present, "the typical unprotected PC will come under attack within 20 minutes of being connected" (Desmond, 2004, p. 1). For a company with more than 100 users, this is potentially damaging not only to the flow of the work day but to a company's reputation with the consumer. A personal firewall for a network is larger in size as it protects all computers within that network. Additionally, each individual local area network (maybe organized by company department and levels of security importance) is protected by its personal firewall, allowing for additional protection of information. This means, more and more companies are using information to ensure the backgrounds of employees as the information they handle becomes more and more top secret. "
