Secure Browser Tool for Proactive Whitelist Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual desktop infrastructure (VDI) environments, administrators face challenges in managing access to content from new network addresses, requiring manual updates to whitelists, which can be time-consuming and inefficient, especially when users need to access new content sources.
Innovation Solution
A secure browser with a specialized tool that proactively identifies and assesses new network addresses within content accessed by multiple users, allowing automatic or prompted addition to the whitelist based on usage frequency and network type, enabling proactive updating without user requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual updates to whitelists are used, then security control is maintained, but time consumption increases and efficiency decreases
Solution Approach 1:
The system performs preliminary action by proactively scanning webpages and identifying network addresses before users need to access them. The specialized tool continuously monitors content and pre-evaluates potential network addresses, so when users need access, the whitelisting decision is already prepared. This eliminates the need for reactive manual updates after access failures occur.
Solution Approach 2:
The system implements self-service by having the specialized tool automatically evaluate and manage whitelist updates without human intervention. The tool independently scans webpages, identifies network addresses, assesses their legitimacy based on predefined criteria, and updates the whitelist autonomously. This removes the burden from administrators to manually manage whitelist updates.
2Speed
If proactive identification of network addresses is implemented, then response time is enhanced, but system complexity increases
Solution Approach 1:
The system segments the complex task of network address management into distinct functional modules: (1) webpage scanning module that extracts network addresses, (2) assessment module that evaluates legitimacy based on criteria like frequency and user behavior, (3) Whitelisting module that updates the whitelist. This segmentation allows each module to be optimized independently and simplifies the overall system architecture.
Solution Approach 2:
The specialized tool acts as an intermediary between the secure browser and the whitelist management system. It receives web content, processes it through assessment criteria, and generates whitelisting decisions. This intermediary layer abstracts the complexity from the main system, allowing the secure browser to remain simple while the specialized tool handles the complex evaluation logic.
3Ease of operation
If automatic assessment of network addresses is used, then ease of operation is improved, but measurement precision requirements increase
Solution Approach 1:
The system implements feedback mechanisms where user access behavior to network addresses is monitored and fed back into the assessment process. When users successfully access content from a network address, this positive feedback reinforces its legitimacy. The system continuously adjusts its assessment based on observed usage patterns, making the automatic evaluation more accurate over time without requiring manual intervention.
Solution Approach 2:
The assessment system uses multiple measurable parameters to evaluate network addresses, including frequency of occurrence, user behavior patterns, and contextual information from webpages. By changing and combining these parameters dynamically, the system achieves high measurement precision through automated assessment. The parameters are adjusted based on the specific context and type of network address being evaluated.
Data Source
AI summary
A technique provides access to content within a computing environment. The technique involves identifying a network address to a resource which is currently blocked from being accessed via the network address due to operation of a content filter. The technique further involves, based on previously accessed content, modifying the operation of the content filter to unblock access to the resource via the network address. The technique further involves, after the operation of the content filter is modified to unblock access to the resource via the network address, permitting access to the resource via the network address.
