Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud computing systems are vulnerable to ransomware attacks that encrypt client data, bypass standard antivirus protections, and can target hardware components, posing a risk of data loss or inappropriate dissemination.
Innovation Solution
Implementing a monitoring solution at a low-level processing space to detect and monitor specific microprocessor instructions, using a user space library and memory translator to identify encryption/decryption routines, and employing a repaving system to restore instances to a pre-attack state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard anti-virus protections are used, then basic security is maintained, but hardware-level ransomware attacks can bypass these protections and encrypt client data
Solution Approach 1:
The patent segments security monitoring into multiple layers: user-space library monitoring application-level encryption instructions, kernel-space driver monitors system-call-level instructions, and hardware performance counter monitoring tracks microprocessor-level encryption/decryption instructions. This multi-layered segmentation enables comprehensive detection of hardware-level ransomware attacks that bypass traditional anti-virus protections.
Solution Approach 2:
The patent introduces intermediary components between the hardware and the operating system: a user-space library acts as an intermediary to detect encryption instructions in user space, while a kernel-space driver serves as an intermediary to detect encryption instructions at the system-call level. These intermediaries enable detection of ransomware attacks without requiring changes to the underlying hardware or operating system core.
2Reliability
If encryption/decryption instructions are monitored at the microprocessor level, then ransomware attacks can be detected, but system complexity increases with multiple monitoring layers
Solution Approach 1:
The patent creates a universal monitoring framework where a single multi-functional system performs multiple detection tasks across different abstraction levels. The combination of user-space library, kernel-space driver, and hardware performance counter monitoring works together as an integrated system to detect ransomware attacks, eliminating the need for separate specialized monitoring systems for each layer.
Solution Approach 2:
The monitoring system utilizes existing hardware resources (performance counters, instruction caches) and operating system mechanisms (system calls, user-space libraries) to perform detection, rather than requiring dedicated specialized hardware or complex custom kernel modifications. This self-service approach leverages available infrastructure to reduce overall system complexity.
3Reliability
If cloud workloads are dynamically reallocated based on attack detection, then compromised resources can be isolated, but service continuity may be affected during migration
Solution Approach 1:
The patent implements preliminary action by pre-configuring the monitoring framework and establishing baseline metrics for normal encryption/decryption behavior before attacks occur. The system continuously collects performance data and establishes thresholds in advance, enabling rapid detection and response when anomalies indicate ransomware attacks, thus minimizing service disruption during isolation and migration.
Solution Approach 2:
The monitoring thresholds and detection criteria are dynamically adjusted based on collected performance data and observed encryption/decryption patterns. The system adapts to legitimate workload variations while maintaining sensitivity to ransomware attacks, enabling accurate real-time detection that preserves service continuity by avoiding false positives that would trigger unnecessary workload migration.
Data Source
AI summary
The present embodiments relate to identifying a ransomware attack. One embodiment relates to a method comprising configuring an operating system to collect metrics related to a hardware component. A message can be received from a user space library to validate an instruction detected in a cache, the instruction being associated with the hardware component. A metric can be compared to a threshold metric. The metric can be associated with the hardware component. A likelihood of a ransomware attack can be determined based at least in part on the comparison. A message can be transmitted to the user space library comprising the determination of the likelihood of the ransomware.
