Automated network blocking method and system

Abstract

A method and system for logically disconnecting a host computer from a network and for reconnecting it in the same manner, such that physical rewiring is not required. The method and system provides security during a virus attack by rapidly isolating an affected host, thereby preventing attack propagation. Logical connections are managed using a network filter to suspend all traffic from a given network host. The network filtering may be implemented as a network protocol or as an administrative tool from a network server.

Description

technical field [0001] The present invention relates generally to computer network security systems, and more particularly to controlling network connectivity. Background technique [0002] In order to prevent attacks from others, computer security and network security are very important nowadays, especially when computers and networks are connected to the Internet or other unreliable networks. These attacks can be in the form of computer viruses, worms, denial of service, improper data access, or other types of malicious software, generally referred to as viruses. Communications network security in general, and computer network security in particular, are often the subject of highly sophisticated attacks by unauthorized intruders, including hackers. Intruders of these networks are increasingly adept at exploiting network weaknesses to gain access and unauthorized privileges, making it difficult to detect and track such attacks. Furthermore, security threats from malware s...
