Deploying Firewalls throughout Your Organization

Cover Image

Avoiding security breaches requires firewall filtering at multiple external and internal network perimeters. Firewalls have long provided the first line of defense in network security infrastructures. They accomplish this by comparing corporate policies about users' network access rights to the connection information surrounding each access attempt.


To best protect against improper system access, it is imperative for businesses to install firewalls at every major interconnectivity point in the network, both internally and externally. This white paper provides a full overview of how to deploy firewalls across your organization, including:


  • Key considerations for protecting all points of network access
  • Internal vs. external attacks
  • The firewall's role in the overall security architecture
  • How firewalls are evolving
