Abstract:
1. An automated computer-implemented method for restricting accessibility to harmful content on a computer network that includes hosts and connectors between the hosts, the method comprising: exploring, by a system of at least one computer running under program control, network pathways to a plurality of investigated hosts, wherein each investigated host is accessed from a plurality of diverse network connectivity access points into the computer network; checking, by the system, if any of the investigated hosts are malicious hosts that are believed to contain harmful content; for any of the investigated hosts that are malicious hosts determined as a result of the checking, identifying, by the system, intermediary hosts having connectors to those malicious hosts based on the exploring of the network pathways; and associating, by the system, an access restriction with each of the intermediary hosts that restricts access to the corresponding intermediary host.
