Vulnerability Event Protection Module for Dynamic Security Policy Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems are vulnerable to infections and attacks during updates of operating systems or host protection software, leading to temporary disabling of protective services, which can leave devices exposed to vulnerabilities.
Innovation Solution
A vulnerability event protection module that monitors for updates and dynamically switches between security policies based on the vulnerability level, enforcing stricter policies during updates to protect against potential threats and reverting to previous policies once the update is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If host protection services are disabled during updates, then system reliability is improved through updates, but security protection deteriorates temporarily
Solution Approach 1:
The system performs preliminary actions by detecting update events before they complete and proactively applying enhanced security policies during the vulnerable period. The vulnerability event protection module monitors for update events and switches to stricter security policies before the update process finishes, preventing exploitation of the temporary vulnerability window.
Solution Approach 2:
The system prepares compensatory security measures in advance by having multiple security policy sets ready. When an update event is detected, the system switches to a second set of security policies that provide enhanced protection during the vulnerable period, cushioning against potential attacks that would exploit the disabled host protection services.
2Object-affected harmful factors
If security policies are switched dynamically, then security protection is improved during updates, but system complexity increases
Solution Approach 1:
The security policy management is segmented into distinct sets of policies. The system maintains a first set of security policies for normal operation and a second set of security policies for update events. This segmentation allows the system to switch between predefined policy sets based on the operational state, simplifying the management complexity while maintaining dynamic adaptability.
Solution Approach 2:
The system implements dynamic security policy switching based on detected update events. The vulnerability event protection module continuously monitors system state and automatically transitions between security policy sets, enabling the security posture to adapt dynamically to changing system conditions without manual intervention.
3Difficulty of detecting and measuring
If monitoring is performed continuously for vulnerability events, then detection capability is improved, but processing overhead increases
Solution Approach 1:
The vulnerability event protection module performs periodic monitoring for specific update events rather than continuous comprehensive security scanning. The system checks for update events at regular intervals and switches security policies based on detected events, reducing processing overhead while maintaining effective detection capability for the critical vulnerability windows.
Data Source
AI summary
A computer-implemented method to protect against a vulnerability event is described. A first set of security policies is enforced. A client device is monitored for a vulnerability event. Upon detecting a vulnerability event, a vulnerability level corresponding to a current environment is determined. A second set of security policies is selected based on the vulnerability level. The second set of security policies is enforced.
