Printing Device Configuration Agents for Secure Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing devices are often sold unconfigured or with basic configurations that lack security settings, and those with enabled security settings can be reconfigured insecurely by end users, leaving them vulnerable to attacks, especially in organizations without dedicated IT staff.
Innovation Solution
A configuration manager maintains and applies configuration data to printing devices using a configuration agent, generating a configuration identification to ensure consistent and secure settings without requiring dedicated IT staff, allowing for initial configuration and reconfiguration as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If printing devices are sold unconfigured or with basic configurations, then ease of manufacture and device complexity are reduced, but security reliability deteriorates
Solution Approach 1:
The configuration manager applies security configurations to printing devices before they are deployed to customers. The system proactively configures devices with secure settings, including disabling wireless communication and copying functions, before the devices are used, thereby preventing security vulnerabilities from existing in the first place
Solution Approach 2:
The configuration manager enables automated configuration management where the system automatically monitors, detects, and applies configuration changes to printing devices without requiring manual intervention from IT staff. The system self-manages the configuration state, including automatic reconfiguration when security policies are updated
2Reliability
If dedicated IT staff are required to manage printing device configurations, then security reliability is improved, but device complexity and operational overhead increase
Solution Approach 1:
The configuration manager implements automated configuration management where the system automatically monitors, detects, and applies configuration changes to printing devices without requiring manual intervention from IT staff. The system self-manages the configuration state, including automatic reconfiguration when security policies are updated
Solution Approach 2:
The system continuously monitors the configuration state of printing devices and compares it against the desired secure configuration. When deviations are detected, the system automatically triggers reconfiguration actions and verifies that the changes were applied successfully, creating a closed-loop feedback mechanism that maintains security without manual intervention
3Ease of operation
If printing devices are reconfigured by end users, then ease of operation is improved, but security reliability deteriorates
Solution Approach 1:
The configuration manager preemptively counteracts potential insecure configurations by continuously monitoring device settings and automatically restoring secure configurations when changes are detected. The system prevents insecure states from persisting by immediately detecting and correcting user-made changes that would compromise security
Solution Approach 2:
The system continuously monitors the configuration state of printing devices and compares it against the desired secure configuration. When deviations are detected, the system automatically triggers reconfiguration actions and verifies that the changes were applied successfully, creating a closed-loop feedback mechanism that maintains security without manual intervention

AI summary
An approach is provided for configuring printing devices. A configuration manager maintains configuration data for a printing device and provides the configuration data to a configuration agent executing on the printing device. The configuration agent applies the settings specified by the configuration data to the printing device and generates configuration identification data that uniquely identifies the settings. The configuration agent uses the configuration identification data to determine whether the current configuration of the printing device has changed. If so, then the configuration agent acquires and applies configuration data from the configuration manager.
