White Paper Abstract:
Internet crime persists as a business concern. In addition, corporations now operate under the rules of corporate governance and industry mandates that carry strict requirements about controlling information security.
To best protect against improper system access, it behooves businesses to install firewalls at every major interconnectivity point in the network, both internally and externally. Some enterprises estimate that more than 80 percent of their cyber losses are from internal attacks; distributing firewall filtering throughout the organization helps alleviate unauthorized internal access by providing multiple check points.
Firewalls represent the first level of access checking. They work with other security technologies, including intrusion prevention, encryption, and endpoint security, to provide a well-rounded defense-in-depth enterprise security system.
