Firewalls
Internet technology has changed not only the way organizations do business, but also the way they approach network security. The dynamic nature of today’s corporate networks means that they are no longer defined by physical boundaries, but instead by enterprise-wide security policies. To be effective, these policies must include a broad range of security services that govern access to network resources, while protecting these same resources from both internal and external threats.
