Usability and Security of Personal Firewalls
Usability and Security of Personal Firewalls Almut Herzog^ and Nahid Shahmehri^ Dept. of Computer and Information Science, Linkopings universitet,Sweden {almhe, nahsh}@ida.liu.se Abstract. Effective security of a personal firewall depends on (1) the rule granularity and the implementation of the rule enforcement and (2) the correctness and granularity of user decisions at the time of an alert. A misconfigured or loosely configured firewall may be more dangerous than no firewall at all because of the user's false sense of security. This study assesses effective security of 13 personal firewalls by comparing possible granularity of rules as well as the usability of rule set-up and its influence on security. In order to evaluate usability, we have submitted each firewall to use cases that require user decisions and cause rule creation. In order to evaluate the firewalls' security, we analysed the created rules. In ad dition, we ran a port scan and replaced a legitimate, network-enabled application with another program to etssess the firewalls' behaviour in misuse cases. We have conducted a cognitive walkthrough paying special attention to user guidance and user decision support. We conclude that a stronger emphasis on user guidance, on conveying the design of the personal firewall application, on the principle of least privilege and on implications of default settings would greatly enhance both usability and security of personal firewalls. 1 Introduction In times where roaming users connect their laptops to a variety of public, pri vate and corporate wireless or wired networks and in times where more and more computers are always online, host-based firewalls implemented in soft ware, called personal firewalls, have become an important part of the security armour of a personal computer. -

Fowdur, Member IEEE and L.Veerasoo [email protected] [email protected] Department of Electrical and Electronic Engineering University of Mauritius Mauritius Abstract- Spoofing is a serious security issue for email overview of some recent anti-spoofing mechanisms is now applications. Although several anti-email spoofing techniques presented have been developed, most of them do not provide users with sufficient control and information on spoof attacks. In this paper In [11], the authors proposed an anti-spoofing scheme for IP a web-based client oriented anti-spoofing email application is packets which provides an extended inter-domain packet filter proposed which actively detects, monitors and controls email architecture along with an algorithm for filter placement. A spoofing attacks. When the application detects a spoofed security key is first placed in the identification field of the IP message, it triggers an alert message and sends the spoofed header and a border router checks the key on the source message into a spoof filter. Moreover, the user who has received packet. If this key corresponds to the key of the target packet, the spoofed message is given the option of notifying the real sender of the spoofing attack. In this way an active spoof control the packet is considered valid, else it is flagged as a spoofed is achieved. The application is hosted using the HTTPS protocol packet. A Packet Resonance Strategy (PRS) which detects and uses notification messages that are sent in parallel with email different types of spoofing attacks that use up the resources of messages via a channel that has been secured by the Secure the server or commit data theft at a datacenter was proposed in Socket Layer (SSL) protocol. -

Cases of IP Address Spoofing and Web Spoofing —
3-3 StudiesonCountermeasuresforThwarting SpoofingAttacks—CasesofIPAddress SpoofingandWebSpoofing— MIYAMOTO Daisuke, HAZEYAMA Hiroaki, and KADOBAYASHI Youki This article intends to give case studies for of thwarting spoofing attack. Spoofing is widely used when attackers attempt to increase the success rate of their cybercrimes. In the context of Denial of Service (DoS) attacks, IP address spoofing is employed to camouflage the attackers’ location. In the context of social engineering, Web spoofing is used to persuade victims into giv- ing away personal information. A Web spoofing attacker creates a convincing but false copy of the legitimate enterprises’ web sites. The forged websites are also known as phishing sites. Our research group developed the algorithms, systems, and practices, all of which analyze cybercrimes that employ spoofing techniques. In order to thwart DoS attacks, we show the deployment scenario for IP traceback systems. IP traceback aims to locate attack source, regardless of the spoofed source IP addresses. Unfortunately, IP traceback requires that its sys- tems are widely deployed across the Internet. We argue the practical deployment scenario within Internets of China, Japan, and South Korea. We also develop a detection method for phishing sites. Currently, one of the most important research agenda to counter phishing is improving the accuracy for detecting phishing sites. Our approach, named HumanBoost, aims at improving the detection accuracy by utilizing Web users’ past trust decisions. Based on our subject experiments, we analyze the average detection accuracy of both HumanBoost and CANTINA.

Traffic Control for Multi-homed End-hosts via Software Defined Networking Anees Mohsin Hadi Al-Najjar B.Sc. (Computer Science), M.Sc. (Computer Science) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2019 School of Information Technology & Electrical Engineering Abstract Software Defined Networking (SDN) is an emerging technology that allows computer networks to be more efficiently managed and controlled by providing a high level of abstraction and network programmability. Having powerful abstractions and pro- grammability via a centralised network controller provides new potential improve- ments to computer networks, such as easier network management, faster innovation and reduced cost. SDN has been successfully applied in wide area and data centre networks, and has achieved a significant improvement in network performance and efficiency. However, using SDN to control network traffic in end-host devices has not been investigated thoroughly. The research presented in this thesis aims to address this gap and inves- tigates the potential benefits of SDN for end-hosts. This thesis explores the feasibility of applying the SDN methodology to control network traffic on multi-homed end de- vices. The objective was to create a control mechanism by changing the network stack on the client in a way that is transparent to the application layer, the network infras- tructure, and other hosts on the network. In contrast to other solutions such as MPTCP, which require a protocol stack upgrade on all the participating nodes, the approach presented in this thesis allows quick and easy client-side-only deployment. This thesis presents an architecture for embedding SDN components, i.e.
