Quarantine Zones for Isolating Misbehaving Computer Processes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for handling misbehaving application processes in computer systems often result in system disruption and hinder diagnosis, as they either automatically shut down processes, leaving systems vulnerable, or require lengthy manual shutdowns, which can lead to prolonged exposure and diagnostic challenges.
Innovation Solution
Isolating misbehaving processes by moving them into quarantine zones where they can continue to function separately from other processes, allowing for testing and remedial actions like rehabilitation or termination, with separate zones used to prevent contamination and minimize system impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic shutdown is used to handle misbehaving processes, then system security is improved, but system availability and diagnostic capability deteriorate
Solution Approach 1:
The patent extracts the misbehaving process from the normal system environment by moving it to a quarantine zone. This isolation allows the system to maintain security by separating the problematic process while preserving system availability, as the process remains contained but accessible for analysis and potential recovery.
Solution Approach 2:
The quarantine zone acts as an intermediary environment between the normal system and misbehaving processes. This intermediate space allows security personnel to analyze and remediate processes without direct exposure to the main system, balancing security requirements with system availability.
2Difficulty of detecting and measuring
If manual shutdown is used to handle misbehaving processes, then diagnostic capability is improved, but system vulnerability increases
Solution Approach 1:
The system performs preliminary isolation by moving misbehving processes to quarantine zones before full analysis or remediation. This preliminary action secures the system immediately while preserving the process for later diagnostic examination, thus reducing vulnerability without sacrificing diagnostic capability.
3Object-generated harmful factors
If process shutdown is used to stop misbehavior, then harmful effects are eliminated, but system complexity increases due to remediation requirements
Solution Approach 1:
The quarantine zone converts the harmful misbehving process into a beneficial diagnostic opportunity. By containing rather than destroying the process, the system can analyze the misbehavior to understand and prevent future incidents, transforming a security threat into a learning opportunity that reduces long-term system complexity.

AI summary
When a computer system process is acting contrary to the rules established for that process for the resource it is running on, the process is moved to a quarantined section and its continued operation is isolated from other processes. While in isolation, the quarantined process is tested and appropriate action, such as, for example, rehabilitation, change of the rules, or termination, is performed. The divided quarantined sections are used for each misbehaving process.
