Keeping a network secure these days is an active job. Network administrators are being asked to protect more and more with limited resources. Detecting and correcting vulnerabilities takes constant work and attention. Enter Active Security. Active security is automated enforcement of network security policies.
Active security is a proactive role in protecting a networks assets.
The idea behind this type of security management is automatically and intelligently detecting security vulnerabilities with automatic response to remedying shortcomings. The security system is truly integrated all working in concert to automatically detect and address any security vulnerability that would violate the security policy. The firewalls are essentially security enforcement points separating a trusted network from an untrusted one, such as the Internet. Firewalls screen traffic permitting only authorized traffic to pass. They are not capable of observing suspicious activity and modifying their protection as a result.
