A plurality of logical nodes are identified from a plurality of elements on a network, where the plurality of elements include security devices. One or more path entries may be determined for at least some of the logical nodes. Each path entry is associated with one of the logical nodes and specifies a set of communication packets, as well as a next node to receive the communication packets from the associated node. The path entries are used to characterize at least a substantial portion of a network path that is to carry communication packets in the set of communication packets.

A method for distributed management of phrase-based security policy, the security policy applied with respect to a digital medium, the method comprising: storing at least one phrase together with accompanying security policy; assigning an owner to at least one of the stored phrases; scanning and analyzing the digital medium in order to locate and identify the at least one stored phrase; upon locating the at least one phrase within a digital item in the digital medium: applying the security policy with respect to the digital item, and notifying the owner.

The invention provides an industrial protocol detection method and device, computer equipment and a storage medium, and the method comprises the steps: receiving a target message; judging whether the target message is an industrial protocol message or not; when the target message is the industrial protocol message, judging the state of an integrity detection switch; and when the integrity detection switch is in an off state, performing deep detection on the target message based on a preset industrial control security policy. According to the method, whether deep detection is directly carried out or not can be determined based on the state of the integrity detection switch, and the integrity detection of the message is skipped, so that the method is suitable for a special scene in which the integrity detection of the message is not needed, and on the other hand, the detection method provided by the embodiment of the invention can not interrupt industrial production.
