Event-Driven Cloud Security Posture Management for New Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CSPM solutions are inadequate for continuously scanning large cloud environments due to resource constraints, leaving them potentially exposed between periodic scans, and malicious actors can exploit this by deprovisioning resources during scans.
Innovation Solution
A system that continuously monitors event records for specific event types to initiate real-time or near-real-time inspections of newly provisioned resources, using an inspection controller to detect cybersecurity objects and trigger mitigation actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If periodic scanning is used to reduce resource costs, then resource consumption decreases, but security exposure time increases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring event records and maintaining an inspection schedule that proactively identifies resources before they can be exploited. Event-driven triggers initiate inspections based on resource lifecycle events (creation, modification, deletion) before security vulnerabilities can be exploited, thus preventing security exposure rather than reacting to it after periodic scans.
Solution Approach 2:
The inspection system transitions from static periodic scanning to dynamic event-driven inspection. The inspection frequency and timing adapt based on resource events - resources are inspected immediately when creation or modification events occur, rather than waiting for the next periodic scan cycle. This dynamic approach ensures continuous security coverage without constant resource consumption.
2Reliability
If continuous scanning is implemented to eliminate security exposure, then security coverage improves, but resource consumption increases
Solution Approach 1:
Instead of performing excessive continuous scanning of all resources, the system applies partial action by selectively inspecting only those resources that have triggered event records (creation, modification, deletion events). This targeted approach provides sufficient security coverage for changed resources without the resource consumption of scanning every resource continuously.
Solution Approach 2:
The system uses event records generated by the cloud environment itself to trigger inspections. Rather than externally initiating continuous scans, the cloud infrastructure's own event logging mechanism serves the security inspection function - events naturally occurring in the system trigger the necessary security checks, eliminating the need for additional continuous scanning resources.
3Use of energy by moving object
If event-driven inspection is used to inspect only changed resources, then resource consumption decreases, but inspection completeness may be compromised
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring event records and using them to trigger subsequent inspections. When resources are created, modified, or deleted, event records provide feedback that automatically initiates inspection of those specific resources. This closed-loop feedback ensures that all security-relevant changes are captured and inspected, maintaining inspection completeness while consuming minimal resources.
Solution Approach 2:
The event-driven inspection system serves multiple functions: it detects security risks, validates resource configurations, ensures compliance with security policies, and provides audit trails. By using the same event-driven mechanism for all these purposes, the system achieves comprehensive inspection coverage without requiring separate scanning processes, thus maintaining completeness while optimizing resource consumption.

AI summary
A system and method for near-real time inspection of a computing environment for a cybersecurity object is presented. The method includes: continuously receiving a plurality of event records, each event record having an event type, and corresponding to an event in the computing environment; detecting in the plurality of event records, an event record of a first type; parsing the event record of the first type to detect a resource identifier, wherein the resource identifier corresponds to a resource deployed in the computing environment; initiating inspection of the resource for a cybersecurity object; and initiating a mitigation action in the computing environment, in response to detecting the cybersecurity object on the resource.
