An Analysis of Denial of Service Attacks on Wireless VoIP
نویسنده
چکیده
In recent years, Wireless Voice over IP (WVoIP) has been one of the most popular telecommunication technologies. Quality of Service (QoS) and security are two important issues which determine the success of WVoIP. WVoIP QoS issues have been extensively studied. However, security issues of WVoIP are rarely addressed. In this paper, we study one important WVoIP security issue of Denial of Service (DoS) attacks. DoS attacks not only degrade WVoIP call quality, but also disconnect active calls and prevent making new calls. We conducted extensive testing on the DoS attacking mechanisms and their effects on WVoIP quality. One major contribution is that we discuss and demonstrate solutions to resolve some DoS attacks on WVoIP. Another contribution of this paper is an experimental framework to emulate the DoS attacking process and to study its effects on WVoIP. A summary of open issues and directions for future research are also provided in this paper.

Detecting Denial of Service Message Flooding Attacks in SIP based Services
Increasing the popularity of SIP based services (VoIP, IPTV, IMS infrastructure) lead to concerns about its security. The main signaling protocol of next generation networks and VoIP systems is Session Initiation Protocol (SIP). Inherent vulnerabilities of SIP, misconfiguration of its related components and also its implementation deficiencies cause some security concerns in SIP based infra...

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 کاملEvaluation 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...

In this paper, Cross-layer design has been used to provide quality of service (QoS) and security at the same time for VOIP over the wireless ad-hoc network. In this paper the authors extend their previous work (i.e. Multi-path Multi-Channel Protocol Design for Secure QoS-Aware VOIP in Wireless Ad-Hoc Networks) by adding transport and application layers considerations. The goal of this paper is ...

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...
