Because of the increased reliance on powerful, networked computers to help run businesses and
keep track of our personal information, entire industries have been formed around the practice of
network and computer security. Enterprises have solicited the knowledge and skills of security experts
to properly audit systems and tailor solutions to fit the operating requirements of their organization.
Because most organizations are increasingly dynamic in nature, their workers are accessing critical
company IT resources locally and remotely, hence the need for secure computing environments has
become more pronounced.
Unfortunately, many organizations (as well as individual users) regard security as more of an
afterthought, a process that is overlooked in favor of increased power, productivity, convenience, ease
of use, and budgetary concerns. Proper security implementation is often enacted postmortem — after
an unauthorized intrusion has already occurred. Taking the correct measures prior to connecting a
site to an untrusted network, such as the Internet, is an effective means of thwarting many attempts at
intrusion.
