Detecting and Mitigating Memory Usage Attacks in Internet of Everything (IoE) Systems
Core Concepts
This paper proposes a lightweight algorithm to detect and mitigate memory usage attacks on resource-constrained IoE devices by monitoring their real-time memory usage.
Abstract
The paper focuses on analyzing and mitigating memory usage attacks in Internet of Everything (IoE) systems. It first identifies the threat scenario where an attacker can gain access to IoE devices and launch memory usage attacks to disrupt their functionality.
The authors set up a testbed environment using Raspberry Pi and Arduino as IoE devices, and conduct experiments to measure the memory usage and CPU usage of these devices under normal conditions, as well as when subjected to memory usage attacks. The results show a significant increase in memory and CPU usage when the devices are under attack.
Based on the analysis, the authors propose a lightweight algorithm to detect and mitigate memory usage attacks. The algorithm monitors the real-time memory usage of IoE devices and compares it against the normal usage patterns. When an abnormal increase in memory usage is detected, the algorithm takes actions to stop the attack, such as disconnecting the device from the internet and preventing further read/write operations to the memory.
The proposed algorithm is implemented and tested on the Raspberry Pi and Arduino devices, demonstrating its effectiveness in detecting and mitigating memory usage attacks while considering the resource constraints of IoE systems.

How can the proposed algorithm be extended to detect and mitigate other types of resource-constrained attacks in IoE systems, such as CPU usage attacks or network bandwidth attacks
To extend the proposed algorithm to detect and mitigate other types of resource-constrained attacks in IoE systems, such as CPU usage attacks or network bandwidth attacks, several modifications and additions can be made:
CPU Usage Attacks:
The algorithm can be enhanced to monitor CPU usage in addition to memory usage. By incorporating CPU monitoring capabilities, the algorithm can detect abnormal spikes or sustained high CPU usage that may indicate a CPU usage attack.
Thresholds and patterns for normal CPU usage can be established similarly to memory usage, allowing the algorithm to flag and respond to deviations from expected CPU utilization levels.
Response mechanisms can be tailored to address CPU usage attacks, such as limiting CPU-intensive processes, isolating affected devices, or implementing rate limiting on CPU resources.
Network Bandwidth Attacks:
Integrate network monitoring functionalities into the algorithm to track network bandwidth usage across IoE devices.
Define baseline network bandwidth patterns for normal operation and set thresholds for anomalous network traffic that may indicate a bandwidth attack.
Implement actions to mitigate network bandwidth attacks, such as traffic shaping, access control lists, or network segmentation to contain and prevent excessive bandwidth consumption.
By incorporating these enhancements, the algorithm can provide a more comprehensive approach to detecting and mitigating various resource-constrained attacks in IoE systems.
What are the potential challenges in deploying the proposed algorithm in a large-scale IoE environment with heterogeneous devices and varying resource constraints
Deploying the proposed algorithm in a large-scale IoE environment with heterogeneous devices and varying resource constraints may present several challenges:
Device Compatibility:
Ensuring the algorithm is compatible with a wide range of IoE devices with diverse architectures, operating systems, and memory/CPU capabilities.
Addressing interoperability issues between different devices to enable seamless integration and operation of the algorithm across the IoE ecosystem.
Scalability:
Managing the scalability of the algorithm to handle a large number of devices simultaneously while maintaining real-time monitoring and response capabilities.
Optimizing resource utilization to prevent performance degradation as the number of monitored devices increases.
Security and Privacy:
Safeguarding the algorithm and its data against potential security threats and ensuring the privacy of sensitive information collected during monitoring.
Implementing robust authentication and access control mechanisms to prevent unauthorized access to the algorithm and its functionalities.
Resource Constraints:
Adapting the algorithm to operate efficiently within the resource constraints of IoE devices, especially those with limited memory, processing power, and energy capacity.
Optimizing the algorithm's resource usage to minimize impact on device performance and battery life.
Addressing these challenges will be crucial for successful deployment of the algorithm in a large-scale and diverse IoE environment.
How can the memory usage monitoring and attack detection be integrated with other security mechanisms, such as intrusion detection systems or anomaly-based monitoring, to provide a more comprehensive security solution for IoE systems
Integrating memory usage monitoring and attack detection with other security mechanisms in IoE systems can enhance overall security posture and provide a more comprehensive security solution. Here are some ways to integrate these components:
Intrusion Detection Systems (IDS):
Incorporate memory usage patterns and attack detection alerts from the algorithm into the IDS for correlation with other security events.
Use IDS to analyze network traffic, system logs, and behavior anomalies in conjunction with memory usage data to identify potential security incidents.
Anomaly-Based Monitoring:
Combine memory usage monitoring with anomaly detection techniques to identify deviations from normal behavior that may indicate attacks.
Utilize machine learning algorithms to analyze memory usage patterns and detect anomalies that traditional rule-based systems may overlook.
Response Coordination:
Establish automated response mechanisms that trigger when memory usage attacks are detected, including isolating affected devices, blocking malicious traffic, or alerting security teams.
Coordinate responses across different security mechanisms, such as IDS, firewalls, and access control systems, to ensure a synchronized and effective response to security incidents.
By integrating memory usage monitoring and attack detection with other security mechanisms, IoE systems can benefit from a more holistic and proactive security approach that enhances threat detection and mitigation capabilities.
