Embodiment Construction
[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0045]In view of the problem of slow detection speed caused by too many judgment sentences in the existing method, the embodiment of the present invention uses a tree structure to store and classify strategies based on the existing method, so as to reduce the number of judgments and avoid In addition to the strategy traversal comparison, it is even possible to directly detect whether there is a duplicate path in the tree, which saves the comparison of obvious conflict redundant strategies, and thus can achieve the effect of conflict detection faster.
[0046] Such as figure 2 As shown, it is the implementation principle flow of the method for detecting firewall policy conflicts in the embodiment of the present invention. It mainly includes the following steps:
[0047] Step 201, initialize the storage tree; when inser...
