Security in the enterprise is an ever-growing concern. Long gone are the days when a firewall was good enough. Now every bit of every byte of network traffic must be scanned to intercept ever more sophisticated viruses and worms. Preventive measures must not only attempt to secure the access to individual computers but also include strategies to protect virtual private networks and shared resources such as servers and network attached storage. Networks attacks need to be stopped at their entry points before they spread.
To completely protect intellectual property and prevent internal threats, corporations need to implement network security measures within the company between departments such as engineering, accounting, and sales. Similarly, a secure system must prevent a virus or a worm brought in by department from spreading to the entire corporate network within the building, or even to offices of the company located in other parts of the world.
