REAL WORLD Orin Thomas One of the biggest shifts in thinking that has gone on since I became an IT professional is the shift in thinking about the LAN as a protected network environment. When I started out firewalls were placed only at the border between a protected network environment and the Internet. Today s thinking is different in that it recognizes that the LAN is also potentially hostile to the health of systems. This shift of thinking is evident in the features shipped with Windows Vista and Windows Server 2008 namely the improved firewall and technologies such as Network Access Protection NAP . Despite our best intentions not every host that connects to the network we are responsible for managing is entirely under our control. Nothing is stopping a member of the sales team who has been overseas at trade shows for the past three months from connecting his or her laptop computer to the company network upon return. This is not problematic if the member of the sales team has ensured that antivirus protection antispyware and Windows Updates have been applied to that computer while he or she was away from the network. But what if when the laptop computer was away from an environment in which harmful Web content is automatically filtered by Microsoft Internet Security and Acceleration ISA Server 2006 that laptop became infected Without the technologies in Windows Server 2008 the act of connecting that computer to the LAN might activate a virulent worm.
