Abstract: The present invention relate to a policy-based robot managing apparatus and method for managing a plurality of robots, which generate a wide area policy for controlling cooperation between the plurality of robots connected by a network, compare the generated wide area policy with an existing wide area policy to check whether a conflict between the wide area policies occurs, convert the generated wide area policy into local policies applicable to the plurality of robots, and transmit the local policies to the corresponding robots, respectively. According to the embodiments of the present invention, since a policy-based management technique is introduced, it is possible to more efficiently control different kinds of robots having various forms through a wide area policy having a pseudo-code form even though a manager does not know previously set information of the individual network robots.

Abstract: Provided are a system and method for coping with encrypted harmful traffic in hybrid IPv4/IPv6 networks.

Abstract: A network security policy is represented, stored and edited by using a rule object, a condition object, an action object, and their associations. The condition object is a one-packet-condition object, a repeated-packet-condition object or a linear-packet-condition object. The action object is an alert-action object, a packet-drop-action object, a packet-admission-action object, a session-drop-action object, a session-admission-action object, a session-logging-action object, a traceback-action object or an ICMP-unreachable-message-sending-action object.
