Leveraging active firewalls for network intrusion detection and retardation of attack

摘要: A computer network firewall or filter functions normally to pass data on open ports a respective service source associated with an port. In addition, traffic arriving closed may be directed handler for analysis and response. The analyze catalog the type of ports. then send response either fixed tailored nature traffic. respond slowly cause wait response, thereby slowing speed at which potential attacker can identify valid targets proceed past non-valid targets.
