Secure Document Gateway for External Content Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Highly secure environments face challenges in accessing external content due to security risks associated with traditional methods of retrieving and integrating external hyperlinks into documents, which can disrupt document flow and deny users vital information.
Innovation Solution
A system and method for securely providing external content by identifying documents with links, retrieving and converting this content into a secure, embeddable format, and embedding it within the document, while performing security checks and sanitizing untrusted content to ensure safety in restricted network environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If external content is retrieved and embedded into documents, then users gain access to vital information, but security risks increase
Solution Approach 1:
The system performs preliminary security checks and content sanitization before embedding external content into documents. The gateway intercepts documents, validates external links against security policies, retrieves and sanitizes content, then embeds the cleaned content into the document, preventing security risks before they can affect the restricted network environment.
Solution Approach 2:
The gateway acts as an intermediary between the restricted network environment and external content sources. It mediates by intercepting documents, performing security validation, sanitizing external content, and embedding only approved content into documents, thereby protecting the internal network while providing access to external information.
2Object-affected harmful factors
If traditional manual security checking is performed, then security risks are reduced, but time consumption increases and document flow is disrupted
Solution Approach 1:
The system enables self-service security checking by automatically performing security validation, content retrieval, and sanitization processes. The gateway autonomously intercepts documents, checks external links against security policies, retrieves content, sanitizes it, and embeds it into documents without requiring manual user intervention, thereby maintaining security while eliminating time loss and document flow disruption.
3Loss of information
If external content is accessed in real-time, then information freshness is improved, but security risks and network dependency increase
Solution Approach 1:
The system performs preliminary content retrieval and embedding before documents reach the restricted network environment. By intercepting documents at the gateway, validating external links, retrieving content in advance, and embedding sanitized content into documents, the system provides information without real-time network access, reducing network dependency while maintaining information availability.
Data Source
AI summary
A computer-implemented method for securely providing information external to documents may include identifying a document that may include at least one link to content external to the document, retrieving the content external to the document from the link, converting the content external to the document to embeddable content in a secure format that can be embedded within the document and creating a secure version of the document at least in part by embedding the embeddable content that has been converted to the secure format into the document. Various other methods, systems, and computer-readable media are also disclosed.
