Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disparate formats and technologies used in firewalls make it difficult to obtain a unified view of all deployed firewalls in a network, hindering effective management and configuration.
Innovation Solution
A unified firewall policy system that includes a format converter, a browser, and a converter, enabling the conversion of firewall policies between different configuration formats, and allowing users to view and manage policies across various firewall technologies through a unified interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple disparate firewall configuration formats are used to implement firewalls with different technologies, then firewall functionality and adaptability are improved, but system complexity and difficulty in obtaining a unified view increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary between firewalls using different configuration formats. This gateway translates and mediates between disparate firewall configurations, enabling unified management while preserving the diversity of underlying firewall technologies and formats.
Solution Approach 2:
The gateway device is designed with multi-functionality to handle multiple firewall configuration formats simultaneously. It can translate between different formats (e.g., Cisco ASA, Palo Alto, Juniper) and provide a universal interface for managing diverse firewall systems through a single point of control.
2Adaptability or versatility
If multiple disparate firewall configuration formats are used, then support for different firewall technologies is improved, but ease of operation and management difficulty worsen
Solution Approach 1:
The gateway serves as a mediating layer that abstracts the complexity of multiple firewall formats from the user. Administrators interact with the gateway using a unified interface, while the gateway handles the complexity of translating to and from various firewall-specific formats in the background.
Solution Approach 2:
The gateway creates translated copies of firewall configuration rules in different formats. Instead of requiring administrators to manually configure each firewall type, the gateway automatically generates and applies appropriate configuration copies to each target firewall based on the source configuration.
3Adaptability or versatility
If manual conversion between firewall configuration formats is performed, then adaptability to different formats is achieved, but time consumption and productivity are reduced
Solution Approach 1:
The gateway enables self-service automated conversion between firewall configuration formats. When a configuration rule is added or modified on one firewall, the gateway automatically translates and applies the equivalent rule to other firewalls without requiring manual intervention, thereby maintaining format compatibility while significantly improving productivity.
Solution Approach 2:
The gateway performs preliminary translation and conversion actions in advance. When configuring a new firewall rule, the gateway pre-translates the configuration into all required target formats and pre-applies them to the respective firewalls, eliminating the need for subsequent manual conversion operations.
4Loss of information
If a unified view of all firewalls is obtained through manual methods, then overall network security picture is improved, but time consumption and operational complexity increase
Solution Approach 1:
The gateway implements automated feedback mechanisms that continuously monitor and collect status information from all connected firewalls. This feedback loop provides real-time or near-real-time visibility into the state of all firewall rules and configurations across the network, maintaining complete information while minimizing the time and effort required to obtain a unified view.

AI summary
Methods, computer-readable media, systems and apparatuses for firewall policy system are described. The firewall policy system may include a unified format converter, a firewall policy browser, and a firewall policy converter. The firewall policy converter may convert firewall policies between different configuration formats. A first firewall policy may be received in a first configuration format. The first firewall policy may be converted into a second configuration format, and a command to convert the first firewall policy from the second configuration format into a third configuration format may be received. In response to receiving the command, the first firewall policy may be converted from the second configuration format into the third configuration format. The first firewall policy may be outputted in the third configuration format.
