Regardless of what you call them, Web Application firewalls, Layer 7 firewalls, Next Generation firewalls etc there is a new breed of firewall appliances on the market designed to protect organizations and their data from the ever growing Internet threats. As we have discussed before data theft, web site hacking and denial of service attacks have become big business. These threats are no longer from some script kitty with a DSL account but are now parts of organized crime rings with the money and technology to pose a serious threat to any organization. Couple that with end users who demand more freedom to work away from the traditional office and you have a serious issue when it comes to effective corporate security. Your edge firewall with flashing lights is no longer an effective security strategy.
While current generation firewalls have had some ability to be application aware, they do not have the inspection capabilities to deal with the large number of applications that exist and typically do not handle port hopping techniques or inspection of encrypted traffic well. Next generation firewalls are designed to deal with these environments and more. Using sophisticated layer 7 inspection capabilities these devices no longer simple perform packet by packet or flow by flow inspection, they are application aware and understand how the application operates and therefore are able to detect actions that are considered abnormal.
Next generation firewalls also give the organization much more granular control over user access based on time of day, application, userID etc allowing the organization to allow, block, or throttle a users’ access. In addition, the user may only be granted access to certain functions within the application. This level of control and inspection gives the organization the control and security needed while allowing the users access to their resources while outside the office.
