A Firewall is a piece of hardware and/or software which functions in a networked environment to prevent some communications forbidden by the security policy, analogous to the function of firewalls in building construction. A firewall is also called a Border Protection Device (BPD), or packet filter in BSD contexts. A firewall has the basic task of controlling traffic between different zones of trust.

Advanced evasions will break the security protection model that most organizations are using today. Given this changing threat landscape we need to rethink traditional security models. Here’s advice on how to evade AETs.
As cyberattacks and fraud continue to increase in frequency and sophistication, organizations are placing a greater emphasis on cyberthreat intelligence as a way to protect against compromise, data breach, and losses from online fraud. Measuring the true value of threat intelligence has been difficult however.
For the first time the Ponemon Institute has conducted a study that reveals the facts behind the impact that weak threat intelligence is having on organizations.
Beyond the basics in a next generation firewall, to protect your investment you should demand other valuable features: intrusion prevention, contextual rules, advanced evasion analytics, secured access control, and high availability.
For decades, fear has dominated the discussion of cyber security. Every magazine article, presentation or blog about the topic seems to start the same way: trying to scare the living daylights out of you with horror stories, alarming statistics, and doomsday scenarios. The result is that most IT shops and security vendors think security is only about what you prevent. They think it’s about blocking, prohibiting, controlling, constraining, excluding, outlawing, and forbidding. Hence IT’s reputation as the “Department of No.”
