Abstract: Presented herein are techniques for creating a policy block comprised of a group of lines of rules/statements across configuration files for network devices. An algorithm is provided that determines when multiple policies are to be merged together into one policy. In one embodiment, data is uploaded from a network that includes a plurality of network devices. The data represents policy rules configured on the plurality of network devices. The data representing the policy rules is compared for similarities in order to group together policy rules based on their similarities. Data is stored representing a plurality of clusters, each cluster representing a group of policy rules that have been grouped together. One or more configuration policies are generated to be applied across the plurality of network devices using the data representing each of the plurality of clusters, while maintaining context of policy rule processing.

Abstract: A method is performed at a management device to manage multiple network security devices over a network. The security devices are configured to control access to network accessible resources. A query is received. In response to the received query, a respective native security rule that references the specific resource is collected from each security device, where each native security rule is based on a respective native rule model associated with the security device from which the native security rule is collected. Each native security rule is translated into a respective normalized rule that is based on a generic rule model. The respective normalized rules are compared to each other to generate compare results. Based on the compare results, an indication of whether each security device allows or blocks access to the specific resource is generated.

Abstract: An integrated development environment (IDE) preprocesses a configuration file including security rules. The preprocessing maps object names in the security rules to associated object values based on object definitions for the object names. Responsive to the configuration file being opened in an editor, the IDE provides the editor with access to preprocessing results. Each security rule in the opened configuration file is searched for object names. The IDE links each object name found in the search to an associated object value mapped thereto by the mapping performed during the preprocessing. The IDE receives a selection of an object name in a security rule of the opened configuration file and generates for display the associated object value linked to the selected object name.
