Green Patterns in Web Design

The internet is a system that was introduced over 30 years ago and has taken over the world since then. Connecting over 5 billion people is possible thanks to the global scale that the internet operates at. While the advantages are unmistakable, we must also acknowledge that the internet is a large contributor to the emission of greenhouse...

Routing based on User Requirements

The versatility of the internet enables many applications that play an increasingly bigger role in our society. However, users have little control over the route that their internet traffic takes, which prevents them from controlling who sees their packets and how their traffic is handled. Researchers have proposed an extension to the internet,...

Measuring accessibility of popular websites while using Tor

Tor is an anonymity network used by a vast number of users in order to protect their privacy on the internet. It should not come as a surprise that this service is also used for abuse such as Denial of service attacks and other malicious activities because of the anonymity it provides. For protecting themselves from this abuse, websites block...

Global Monitoring and Visualization of the Internet

The internet consists of many networks connected by the BGP protocol and can easily be manipulated by a hacker. Every day, hackers reroute internet traffic and use that to impersonate entities such as companies, devices and humans. To detect this rerouting, which is also know as a route leak, a BGP monitor can be used. A BGP monitor checks...

The Interface

Due to the Internet, and more importantly its interfaces we carry, we have gained freedom to do whatever, wherever, whenever. All the fields of interaction with the Internet are called the Interface in this research. The Interface automates human actions. In many aspects of life, automation by the Interface has an impact. In this research, it is...

Analysing BGP Origin Hijacks

In the past years, society has become increasingly more reliant on the Internet. Consequently, the security of the Internet became of critical importance. This thesis focusses on the security of one of the Internet's main protocols. This protocol, called the Border Gateway Protocol (BGP), is used to exchange information that allows Internet...

An Empirical Study into Factors that Create Configuration Inconsistencies between IPv4 and IPv6 Systems: Identifying the Managerial and Scientific Implications

In this study, a analysis was performed to analyze why there are differences in port configuration between IPv4 and IPv6. For this, the current state of adoption and implantation processes of IPv6 were researched. Currently, 4,8% of all dual-stack hosts have a different configuration in open ports on IPv4 and IPv6. To discover the reasoning...

Placement Strategies to Monitor the Inter-Autonomous System Routing Information

Inter-Autonomous System (AS) route monitoring is the process of collecting the inter-AS routing information. This information flows on the Internet in the form of BGP UPDATE messages, and the BGP data are the messages obtained by the monitors. Existing methods of monitor placement rely on the network topology which provides inadequate visibility...

PaDAWaNS: Proactive Domain Abuse Warning and Notification System

The counterfeit market is rapidly expanding into the online realm. Large amounts of fraudulent webshops advertise luxury clothing and fashion accessories, but ship counterfeit products to their customers. Apart from customers, brand owners and domain registries experience a negative impact caused by these fake webshops. Current countermeasures...

Inferring relationship types and simulating BGP traffic between Autonomous Systems using the valley-free constraint

In today's world, the Internet is the backbone of our society. The relatively unknown Border Gateway Protocol (BGP), and with its vulnerabilities, gives malicious parties an opportunity for abuse. By improving the currently known AS relation data set and by simulating BGP traffic this abuse is better spotted. Kastelein's topology generating...

Real time distributed simulation of BGP on the entire current Internet topology and Internet-like topologies

The Border Gateway Protocol is critical for the correct working of the Internet. When it fails the impact is usually high and therefore failures should be minimized. Unfortunately the configuration of BGP is prone to errors. Besides that, BGP is targeted by attacks of cyber criminals. A simulator capable of running BGP can reduce the number of...

Data Analytics in Web-based Education in the Higher-education Classroom

Attention span of students in a classroom is very short. To overcome this, different active learning methodologies have been used in the past. Active learning keeps the students busy and engaged throughout the lecture. It breaks the lecture into certain time intervals by intermixing breaks, demonstrations and questions after each interval. For...

Diversified Bits and Pieces: Patterns and Motives of Diversification Strategies of Internet-based Firms

The goal of the thesis is to identify patterns and motives of diversification strategies of internet-based firms. This corporate strategy of entering new markets with new products has mainly focused on conventional firms. However, since the raise of the Internet the characteristics of firms have changed. The study involves the online character...

Anonymous Internet: Anonymizing peer-to-peer traffic using applied cryptography

Throughout the years the Internet became of indispensable value to social, economic and political life. Despite this, the Internet in all its forms and protocols has proven to be extremely sensitive to manipulation by forces in control of the infrastructure of the Internet. Along with the growth of The Internet came the growth of censorship and...

Botnet Mitigation and the Role of ISPs: A quantitative study into the role and incentives of Internet Service Providers in combating botnet propagation and activity
