Enterprises often overlook the firewall — that simple black box out at the edge of the network, quietly performing packet inspection on incoming traffic. Newer, more-sophisticated perimeter security products that offer intrusion prevention, vulnerability scanning and active network monitoring are getting far more industry attention than firewalls. However, firewall technology is not outdated or redundant. A well-deployed firewall remains your first line of defense against external attacks. Also, vendors in this market segment are evolving to meet changing security needs by improving baseline performance and adding new functionality.
Firewall technology is on the verge of its most significant change since the introduction of stateful packet inspection, which likely will alter the vendor landscape. This change will be driven by the emergence of deep packet inspection and other application capabilities, and it will benefit agile vendors that can rapidly incorporate the most-desirable new functionalities. Because of the continuing importance of this technology, as well as upcoming changes in products, vendors and the overall market, we've made firewalls the focus of this issue of the Security & Privacy Spotlight. |
