Internet Background Radiation (IBR) comprises a range of unsolicited traffic directed towards Internet hosts. In general, this type of traffic is characterised by high levels of port scanning activity, malware propagation, application exploits, system misconfiguration and denial-of-service attacks. IBR capture is typically undertaken by a system termed a network telescope. This records unfiltered incoming internet traffic for a specific CIDR block in the form of a packet capture (PCAP) file for analysis. This work proposes a novel, cloud-native approach to capturing IBR by the deployment of an ephemeral and reproducible architecture, described as code, distributed across all regions of a cloud service provider. In this paper we discuss the technical and financial viability of using a fleet of small-sized compute instances, in a spot price auction model, to maximise platform collection, capillarity and duration. We also present an overview analysis of the primary characteristics of IBR as collected during a month long proof-of-concept experiment across 26 regions of a cloud service provider in May 2023. Our analysis discusses the aspects of the dataset in quantitative terms: traffic aggregation per protocol, top TCP and UDP ports, top radiation sources and radiation distribution per cloud region. We also provide an overview of the most relevant threats detected. Our results include a formalisation and validation of the cloud telescope, with the corresponding supporting architecture described in Terraform and Ansible. The aggregate dataset amounted to 2.2 GB, and 21.8 million packets. Composition by protocol was 78% TCP, 14% ICMP and 8% UDP.

Heterogeneous distributedsystems have been widely used in the industrial field to address the demand for scalability and performance. However, with the increase in the number of computing nodes, the energy consumption of the system has sharply risen. Therefore, reducing energy consumption has become an important objective in the field of sustainable computing. To address this challenge, this paper proposes an energy-conscious scheduling algorithm based on heterogeneous computingsystems for allocating and scheduling tasks with different priorities. The algorithm initializes the population based on the Earliest Finish Time (EFT) and processor allocation strategy and adopts the superior individual selection strategy to reduce the influence of inferior solutions. Additionally, the MECMA algorithm introduces a novel adaptive mutation operator to enhance the diversity of the population and accelerate the convergence speed. Simulation experiments have been conducted on a set of randomly generated tasks, and the experimental results have demonstrated the efficiency of the proposed algorithm. The proposed MECMA algorithm has significantly reduced energy consumption and shortened task completion time. The research results have great potential to contribute to the development of sustainable computing and the optimization of energy utilization in industrial fields.
