White Papers: firewall

Organisations strive for leverage to drive down costs, improve business agility and benefit from increased automation and efficiency. In order to deliver performance, organisations compete on how best to remove the barriers of virtualisation and migrate their applications, while managing the associated complexity and risk.

This paper will discuss strategies for controlling a broad range of recreational Internet traffic such as instant messaging, P2P file downloads and social networking activities that can significantly slow business applications and impact employee productivity. By implementing a solution to effectively detect, classify and control recreational traffic, including encrypted P2P traffic designed to slip past corporate firewalls, organisations can improve employee productivity, accelerate application response times, reclaim bandwidth for business-critical applications and defer costly bandwidth upgrades.

Walls have served multiple purposes throughout history. The Great Wall of China defended against invaders, while the Berlin Wall kept citizens from freely traveling beyond the control of their rulers. Network security relies on similar premises. For years network security professionals touted “perimeter security” as the primary solution to keep the bad guys out and the good guys in. However, just as guns and air attacks overcame protective walls, changes in malware attacks have rendered network firewalls and perimeter-centric security an ineffective defense.

The firewall market has traditionally been a staple, yet, mature market within the security space with little innovation being introduced. However, with the rapid change in the technology and threat landscape, a newer breed of of innovation focussing on applications visibility and control, termed Next Generation Firewalls has surfaced. This paper examines how Next Generation Firewalls can help organisations identify and block threat, while at the same time enforcing policies at an application level and ultimately helping organisations reduce the number of security devices and thus, saving costs.

Information ranging from trade secrets to privacy related information has become the target of sophisticated attacks from both sides of the firewall. Protecting data now requires a strategy that enables both preventive and detective controls. Read on.
