Enterprise Password Vault Automating Credential Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy systems relying on user-managed passwords are vulnerable to weak password creation, phishing, and malware attacks due to the difficulty in managing multiple complex passwords and infrequent changes, especially in systems not integrated with OTP or federation systems.
Innovation Solution
An enterprise management system automates the generation and management of strong, short-lived passwords through a password vault, pushing new passwords to both service applications and user devices at high frequency, including the option for one-time use, without requiring integration with specialized authentication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually manage their own passwords for multiple applications, then users have control over password management, but password strength decreases and security risk increases due to weak passwords and infrequent changes
Solution Approach 1:
The password management system operates autonomously without requiring user intervention. The service computer automatically generates passwords, monitors expiration events, updates the vault, and manages password lifecycle events. This self-service approach eliminates the need for users to manually create or remember complex passwords while maintaining strong security through automated frequent password rotation.
Solution Approach 2:
A service computer acts as an intermediary between the user device and multiple applications. It manages the password vault and handles all password-related operations, including generation, storage, and distribution to applications. This intermediary approach centralizes password control, enabling automated security policies without burdening users with management complexity.
2Reliability
If passwords are changed frequently to improve security, then password compromise risk decreases, but user burden increases due to remembering multiple complex passwords
Solution Approach 1:
The automated system continuously manages password rotation without user involvement. When a password expiration event occurs, the service computer generates a new password, updates the vault, and distributes it to applications. Users simply authenticate without needing to remember or manually update passwords, eliminating the burden while maintaining frequent password changes for security.
Solution Approach 2:
The service computer maintains a centralized copy of all passwords in the vault and automatically distributes copies to applications as needed. This centralized copying mechanism allows the same password to be used across multiple applications without requiring users to remember each unique password, reducing cognitive burden while maintaining security through automated rotation.
3Reliability
If strong complex passwords are used to improve security, then resistance to guessing attacks increases, but vulnerability to phishing and malware extraction increases
Solution Approach 1:
The system implements periodic password rotation based on time-based or use-based expiration events. Passwords are automatically renewed at predetermined intervals, limiting the window of opportunity for phishing or malware to successfully extract and utilize credentials. This periodic renewal reduces the impact of credential theft while maintaining strong password complexity.
Solution Approach 2:
The system dynamically changes password parameters including complexity requirements, expiration timing, and rotation frequency. By adjusting these parameters based on security policies and threat levels, the system optimizes the balance between password strength and vulnerability to attacks. Strong passwords are maintained while their lifespan is controlled through automated rotation.
4Reliability
If specialized authentication systems like OTP or federation are integrated into applications, then authentication security improves, but system complexity and integration requirements increase
Solution Approach 1:
The service computer functions as an intermediary that provides centralized authentication management without requiring application integration with complex specialized systems. It manages password generation, storage, and distribution, enabling strong authentication through automated password rotation while keeping legacy applications simple and unchanged.
Solution Approach 2:
The password vault service provides universal password management capabilities that work across multiple applications and systems without requiring specialized integration. A single service computer manages authentication for diverse applications including legacy systems, eliminating the need for application-specific OTP or federation integration while maintaining strong security through centralized automated password control.

AI summary
A computer system includes a management computer for automatically changing a password used to authenticate a user to a service application. A user device includes a password vault managed by a password management application. The management computer monitors for an event signifying that the password is to be changed, e.g., a predetermined number of uses, etc. A new password is assigned, and a first message is generated and sent to the service application including the new password and an indication that it is to be used for subsequent user authentication. A second message is also generated and sent to the password management application, also including the new password and an indication that it replaces a current password in the vault for user authentication. The new password is automatically used by both the service application and the user device during subsequent authentications until expiration.
