Firewalls help hackers break into FB, Twitter?
WASHINGTON, USA: Firewall technology designed to boost security can unwittingly reveal data that could help a hacker break into Facebook and Twitter accounts, a new study says.
Exploit uses firewalls to hijack smartphones, turns friends into foes
Normally, firewalls at cellular carriers are your best friends, screening out malware before it ever touches your phone. University of Michigan computer science researchers have found that those first lines of defense could be your enemy through a new exploit. As long as a small piece of malware sits on a device, that handset can infer TCP data packet sequence numbers coming from the firewall ...
US firms over-reliant on firewalls to defend against DDoS attacks
More than half of US businesses still rely on conventional firewalls or intrusion prevention systems to shield them from the scourge of DDoS attacks, a survey by services firm Neustar has found.

Firewalls can help hackers break into Facebook, Twitter
Washington, May 22: Firewall technology designed to boost security can unwittingly reveal data that could help a hacker break into Facebook and Twitter accounts, a new study says.
How we tested next-generation firewalls
We tested next generation firewalls by looking at seven separate areas that we felt would be important to network managers trying to deploy these products in enterprise networks.
Next-gen firewalls: Off to a good start
When we tested four next-gen firewalls strictly on performance, we found that the products could forward packets at impressive rates, but throughput dropped when advanced security features were turned on. We now dive deep into application identification and control - the defining features of next-gen firewalls - to find out what works and what doesn't.
Next-gen firewalls require external visibility tools
Knowing what's happening on your network is a pre-requisite to controlling the traffic. We call that visibility because it combines all of the information the firewall knows, including session and application information, traffic volumes, and rate information, into a way to "see" into your network -- to give you visibility.
U.S. Firms Over-Reliant on Firewalls to Defend Against DDoS Attacks

Basic firewall functionality: Check Point's maturity shows through
Enterprise firewalls must have policies to control traffic, ability to create site-to-site VPNs using standards-based IPsec, translate addresses and port numbers (NAT) when needed, and apply basic bandwidth management to traffic. They must also support features such as high availability (active/passive or active/active), virtual LANs, Ethernet link aggregation, and global management systems.
