Abstract:

Given the continuing advancement of networking applications and our increased dependence upon software-based systems, there is a pressing need to develop improved security techniques for defending modern information technology (IT) systems from malicious cyber-attacks. Indeed, anyone can be impacted by such activities, including individuals, corporations, and governments. Furthermore, the sustained expansion of the network user base and its associated set of applications is also introducing additional vulnerabilities which can lead to criminal breaches and loss of critical data. As a result, t

Abstract:

<p>Ericsson’s Packet Radio Access Network (PRAN) is a network solution for packet transport in mobile networks, which utilizes the Internet Protocol (IP). The IP protocol offers benefits in responsiveness and performance adaptation to data bursts when compared to Asynchronous Transfer Mode (ATM), which is still often used. There are many manufacturers / operators providing IP services, which reduce costs. The IP’s use on the Internet brings greater end-user knowledge, wider user community and more programs designed for use in IP environments. Because of this, the spectrum of possible attacks

Abstract:

Mobile Networks (MNs) are fundamental infrastructures in modern life. As traffic volumes rise and subscriber needs are expanding, MNOs need to adapt in order to keep up with the demand. This has led to MNOs virtualising the Core Network (CN) by utilising Software Defined Networking (SDN) and Network Functions Virtualisation(NFV). The security and reliability of the MN are under higher levels of scrutiny as more traffic and subscribers make use of the MN. As MNs become more popular so do they become more enticing for malicious actors as targets for attacks. The virtualisation of the CN has led

Att skydda sin IT-miljö mot olika typer av intrång och attacker som till exempel trojaner,skadliga Java applets eller DoS attacker med hjälp av brandväggar och antivirusprogramär två viktiga lager i skalskyddet. I den här uppsatsen undersöks hur väl ett Intrusion Prevention System skulle kunna fungera som ett ytterligare lager i skalskyddet. Fokus ligger på hur väl IPS-systemet klarar av att avvärja attacker, hur mycket tid som går åt till konfigurering och drift för att få ett fungerande IPS samt hur prestandan i nätverket påverkas av implementationen.

Abstract:

As the networks become faster and faster, the emerging requirement is to improve the performance of the Intrusion Detection and Prevention Systems (IDPS) to keep up with the increased network throughput. In high speed networks, it is very difficult for the IDPS to process all the packets. Since the throughput of IDPS is not improved as fast as the throughput of the switches and routers, it is necessary to develop new detection techniques other than traditional techniques. In this thesis we propose a rule-based IDPS technique to detect Layer 2-4 attacks by just examining the flow data without i

Abstract:

Wireless Sensor Networks (WSNs) continue to grow as one of the most exciting and challenging research areas of engineering. They are characterized by severely constrained computational and energy resources and also restricted by the ad-hoc network operational environment. They pose unique challenges, due to limited power supplies, low transmission bandwidth, small memory sizes and limited energy. Therefore, security techniques used in traditional networks cannot be directly adopted. So, new ideas and approaches are needed, in order to increase the overall security of the network.

Intrusion Prevention Systems (IPSs) have long been proposed as a defense against attacks that propagate too fast for any manual response to be useful. While purely-network-based IPSs have the advantage of being easy to install and manage, research have shown that this class of systems are vulnerable to evasion [70, 65], and can be tricked into filtering normal traffic and create more harm than good [12, 13]. Based on these researches, we believe information about how the attacked hosts process the malicious input is essential to an effective and reliable IPS. In existing IPSs, honeypots are us

These schemes have two major drawbacks: (1) the loss of correlation information caused by the traffic distribution because correlated flows are not sent to the same NIDPS and (2) the unbalanced loads of the NIDPSs.
