Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review

Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review
Livestreaming of child sexual abuse is an established form of online child sexual exploitation
and abuse. However, only a limited body of research has examined this issue. The Covid-19
pandemic has accelerated internet use and user knowledge of livestreaming services
emphasising the importance of understanding this crime. In this scoping review, existing
literature was brought together through an iterative search of eight databases containing peer-
reviewed journal articles, as well as grey literature. Records were eligible for inclusion if the
primary focus was on livestream technology and online child sexual exploitation and abuse,
the child being defined as eighteen years or younger. Fourteen of the 2,218 records were
selected. The data were charted and divided into four categories: victims, offenders,
legislation, and technology. Limited research, differences in terminology, study design, and
population inclusion criteria present a challenge to drawing general conclusions on the
current state of livestreaming of child sexual abuse. The records show that victims are
predominantly female. The average livestream offender was found to be older than the
average online child sexual abuse offender. Therefore, it is unclear whether the findings are
representative of the global population of livestream offenders. Furthermore, there appears to
be a gap in what the records show on platforms and payment services used and current digital
trends. The lack of a legal definition and privacy considerations pose a challenge to
investigation, detection, and prosecution. The available data allow some insights into a
potentially much larger issue.

Towards a Lightweight Task Scheduling Framework for Cloud and Edge Platform
Internet of Things; Engineering Cyber Physical Human Systems (2023).Status: Accepted
Towards a Lightweight Task Scheduling Framework for Cloud and Edge Platform
Mobile devices are becoming ubiquitous in our daily lives, but they have limited computational capacity. Thanks to the advancement in the network infrastructure, task offloading from resource-constrained devices to the near edge and the cloud becomes possible and advantageous. Complete task offloading is now possible to almost limitless computing resources of public cloud platforms. Generally, the edge computing resources support latency-sensitive applications with limited computing resources, while the cloud supports latency-tolerant applications. This paper proposes one lightweight task-scheduling framework from cloud service provider perspective, for applications using both cloud and edge platforms. Here, the challenge is using edge and cloud resources efficiently when necessary. Such decisions have to be made quickly, with a small management overhead. Our framework aims at solving two research questions. They are: i) How to distribute tasks to the edge resource pools and multi-clouds? ii) How to manage these resource pools effectively with low overheads? To answer these two questions, we examine the performance of our proposed framework based on Reliable Server Pooling (RSerPool). We have shown via simulations that RSerPool, with the correct usage and configuration of pool member selection policies, can accomplish the cloud/edge setup resource selection task with a small overhead.

How Large Is the Gap? Exploring MANRS and ISO27001 Security Management

How Large Is the Gap? Exploring MANRS and ISO27001 Security Management
Ensuring security of network traffic between op- erators is very important. This paper aims to enhance un- derstanding of the relationship between two crucial internet security standards, namely, Mutual Agreed Norms for Rout- ing Security (MANRS) and ISO/IEC 27001 (ISO27001). By examining the correlation between MANRS participation and ISO27001 certification, this study provides insightful analysis. To validate compliance, data from diverse sources such as CAIDA, PeeringDB, and RPKI is correlated. We assess ISO27001 controls that bear relevance to MANRS compliance and illustrate how implementing either framework leads to a reduced risk of security breaches. Moreover, a cost analysis reveals that the simultaneous implementation of MANRS and ISO27001 does not significantly increase costs or complexity.

Evolved Cold-Potato routing experiences

Evolved Cold-Potato routing experiences
This paper presents a system designed to enhance Quality of Service (QoS) for a global video conferencing service. By a combination of off-the-shelf equipment and open-source software, the proposed system establishes a global service net- work with efficient cold-potato internal routing techniques.
Through 15 years of operational experience, we have developed egress selection heuristics to minimize latency and loss in real- time, end-to-end services. The use of legacy routers and switches guarantees stability and security, while the implementation of specially adapted Route Reflector software provides flexibility.
This study highlights the notable enhancements achieved in terms of accurate egress routing placement, latency reduction, and a significant decrease in customer support cases. By sharing our experiences, we aim to contribute valuable insights to the field of network optimization for real-time services.

A Live Demonstration of HiPerConTracer 2.0
In Proceedings of the 31st International Conference on Software, Telecommunications and Computer Networks (SoftCOM). Split/Croatia, 2023.Status: Accepted
A Live Demonstration of HiPerConTracer 2.0
HiPerConTracer is an open source tool for large-scale, long-term, high-frequency Ping and Traceroute measurements. Using such measurements, it is possible to obtain information about latency in the network, as well as about the actual routing. This proposed live demo provides an overview over the tool and its features, as well as an introduction of how to use it for performing measurements, storing the results, querying selected results, and post-processing them for visualisation.
