Enterprise security necessitates a hierarchy of technologies and processes, and history has proven the firewall as a foundational element of that matrix.
As networks evolve and expand far beyond traditional concepts of the corporate perimeter – driven by mobility, virtualization and the cloud – models of security management have also transformed rapidly.
This advancement has shifted the manner in which organizations seek to protect their critical systems and data. However, effective security management will always retain a multi-layered approach necessitating mechanisms that control and limit access. While this may not someday require dependence on network security devices, in today’s environment the firewall remains one of the critical building blocks of network security.
