Denial of Service Attacks and Challenges in Broadband Wireless Networks

چکیده
Broadband wireless networks are providing internet and related services to end users. The three most important broadband wireless technologies are IEEE 802.11, IEEE 802.16, and Wireless Mesh Network (WMN). Security attacks and vulnerabilities vary amongst these broadband wireless networks because of differences in topologies, network operations and physical setups. Amongst the various security risks, Denial of Service (DoS) attack is the most severe security threat, as DoS can compromise the availability and integrity of broadband wireless network. In this paper, we present DoS attack issues in broadband wireless networks, along with possible defenses and future directions.

Evaluation of an Intrusion Detection System for Routing Attacks in Wireless Self-organised Networks
Wireless Sensor Networks (WSNs) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. However,security is a major challenge for WSNs because they areusually setup in unprotected environments. Our goal in thisstudy is to simulate an Intrusion Detection System (IDS)that monitors the WSN and report intrusions accurately andeffectively. We have thus...
متن کاملIntrusion Detection in IOT based Networks Using Double Discriminant Analysis
Intrusion detection is one of the main challenges in wireless systems especially in Internet of things (IOT) based networks. There are various attack types such as probe, denial of service, remote to local and user to root. In addition to known attacks and malicious behaviors, there are various unknown attacks that some of them have similar behavior with respect to each other or mimic the norma...
متن کاملHF-Blocker: Detection of Distributed Denial of Service Attacks Based On Botnets
Abstract—Today, botnets have become a serious threat to enterprise networks. By creation of network of bots, they launch several attacks, distributed denial of service attacks (DDoS) on networks is a sample of such attacks. Such attacks with the occupation of system resources, have proven to be an effective method of denying network services. Botnets that launch HTTP packet flood attacks agains...
متن کاملDenial-of-Service Attacks in Wireless Networks Using Off-the-Shelf Hardware
Wireless network technologies offer ubiquitous broadband access to millions of users at an affordable cost. However, the broadband nature of the wireless medium make these networks vulnerable to a number of attacks. Malicious interference at the physical layer, and extended packet collisions at the medium access layer can cause significant DoS attacks. In this work, we show how off-the-shelf ha...
متن کاملFramework for Defending against Denial of Service Attacks in Wireless Networks
Wireless mobile nodes have extremely limited resources and are easily vulnerable to Denial of Service (DoS) attacks. The traditional techniques that can detect or prevent DoS attacks in wired networks often require considerable resources such as processing power, memory, and storage space. Hence, it is not possible to deploy the traditional techniques on the wireless nodes. In this paper, we id...
