Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In multi-cloud and hybrid environments, existing single-sign-on protocols like SAML are vulnerable to forged authentication objects, allowing attackers to masquerade as users and go undetected, posing a significant security risk due to the inability to verify authenticity and automatically mitigate such attacks.

Innovation Solution

A system comprising an event inspector, an authentication object inspector, and a hashing engine is implemented to monitor logs, detect vulnerable events, calculate cryptographic hashes for new authentication objects, and validate subsequent access requests, thereby identifying and mitigating forged authentication object attacks by comparing hashes and triggering predefined rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If single-sign-on protocols like SAML are implemented to provide user-friendly access across federated services, then ease of operation is improved, but security reliability deteriorates due to vulnerability to forged authentication objects

Engineering Contradiction:

Improvesingle-sign-on experienceVSAvoidauthentication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by calculating cryptographic hashes of authentication objects at the point of issuance and storing them in a database before they are used for authentication. This advance preparation enables subsequent rapid verification of authentication object authenticity without adding user-facing steps, thus maintaining ease of operation while improving security reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary verification mechanism that sits between the identity provider and service providers. This intermediary component automatically validates authentication objects by comparing their hashes against stored values, preventing forged authentication objects from compromising the federated environment while keeping the single-sign-on experience transparent to users.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If traditional cybersecurity approaches are used to detect suspicious activity, then device complexity is minimized, but detection precision deteriorates allowing attackers to go undetected for extended periods

Engineering Contradiction:

Improvesecurity system structureVSAvoidattack detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system replaces traditional mechanical cybersecurity approaches (manual monitoring, rule-based detection) with cryptographic verification mechanisms. By substituting hash-based authentication validation, the system achieves high detection precision without significantly increasing operational complexity, as the verification process is automatically performed by the system architecture.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates cryptographic copies (hashes) of authentication objects at the point of issuance and stores them for later verification. This copying mechanism enables precise detection of forged authentication objects by comparing against the original cryptographic representation, significantly improving detection precision while maintaining relatively simple system structure.

Inventive Principle:

Principle #26Copying

3Productivity

If authentication objects are trusted without verification to enable federated access, then productivity is improved through seamless authentication, but harmful factors increase due to unauthorized access risks

Engineering Contradiction:

Improvefederated service access efficiencyVSAvoidunauthorized access vulnerability

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements self-service verification where authentication objects automatically validate themselves through cryptographic hash comparison. The verification process is performed automatically by the system infrastructure without requiring user action or manual intervention, thus maintaining high productivity and seamless authentication while eliminating unauthorized access vulnerabilities through automated security validation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

An intermediary verification layer is introduced that automatically validates authentication objects before granting access to federated services. This intermediary mechanism prevents harmful factors by blocking forged authentication objects while maintaining productivity by performing verification transparently in the background without disrupting the user authentication experience.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A system for detecting and mitigating forged authentication object attacks in federated environments is provided, comprising an event inspector to monitor logs and detect vulnerable events, an authentication object inspector configured to observe a new authentication object generated by an identity provider, and intercept the new authentication object; and a hashing engine configured to calculate a cryptographic hash for the new authentication object, and store the cryptographic hash for the new authentication object in the SAML response; wherein subsequent access requests accompanied by authentication objects are validated by comparing hashes for each authentication object to previous generated hashes.
