N2N: a Layer Two Peer-To-Peer VPN
N2N: A Layer Two Peer-to-Peer VPN Luca Deri1, Richard Andrews2 ntop.org, Pisa, Italy1 Symstream Technologies, Melbourne, Australia2 {deri, andrews}@ntop.org Abstract. The Internet was originally designed as a flat data network delivering a multitude of protocols and services between equal peers. Currently, after an explosive growth fostered by enormous and heterogeneous economic interests, it has become a constrained network severely enforcing client-server communication where addressing plans, packet routing, security policies and users’ reachability are almost entirely managed and limited by access providers. From the user’s perspective, the Internet is not an open transport system, but rather a telephony-like communication medium for content consumption. This paper describes the design and implementation of a new type of peer-to- peer virtual private network that can allow users to overcome some of these limitations. N2N users can create and manage their own secure and geographically distributed overlay network without the need for central administration, typical of most virtual private network systems. Keywords: Virtual private network, peer-to-peer, network overlay. 1. Motivation and Scope of Work Irony pervades many pages of history, and computing history is no exception. Once personal computing had won the market battle against mainframe-based computing, the commercial evolution of the Internet in the nineties stepped the computing world back to a substantially rigid client-server scheme. While it is true that the today’s Internet serves as a good transport system for supplying a plethora of data interchange services, virtually all of them are delivered by a client-server model, whether they are centralised or distributed, pay-per-use or virtually free [1]. -

Virtual Private Networ Ks
5 Virtual Private Networ ks 5.1 Introduction In Part 2, we discuss virtual private networks (VPNs). Chapter 4 had some examples of VPNs, but we were interested mainly in their tunneling aspects and didn’t dwell on their security and authentication features. In this chapter, we define VPN and briefly revisit the VPNs from Chapter 4. In the rest of Part 2, we study several types of VPNs, see how they are used, and take note of their strengths and weaknesses. As we shall see, these VPNs can operate at any layer in the TCP/IP stack. As usual, we will be less concerned with the administrative details of configuring the VPNs than with developing an appreciation for the protocols them- selves and the manifestation of those protocols on the wire. Before beginning our discussion of VPNs, we should agree on a definition for them. We already have an implicit definition from our study of MPLS VPNs in Chapter 4. We might say that according to that definition, a VPN is a method of using tunneling to build a private overlay network on top of a public network in such a way that the secu- rity of the private network is equivalent to that provided by leased lines. But this defi- nition suffers from a lack of precision as to the meaning of ‘‘security equivalent to that provided by leased lines’’ and is a bit too general for our purposes. Instead, let us say that a virtual private network is an overlay network built with tunnels in which the tunnel payloads are encrypted and authenticated. -

Security in Packet-Switched Land Mobile Radio Backbone Networks by Hans Olaf Rutger Thomschutz Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering Dr. Scott F. Midkiff, Chair Dr. Luiz A. DaSilva Dr. A. Lynn Abbott May 25, 2005 Blacksburg, Virginia Keywords: Land Mobile Radio, Security, Encryption, Voice over IP Copyright 2005, Hans Olaf Rutger Thomschutz Security in Packet-Switched Land Mobile Radio Backbone Networks by Hans Olaf Rutger Thomschutz Dr. Scott F. Midkiff, Chair (ABSTRACT) Spurred by change in government regulations and to leverage lower-cost technology and services, many land mobile radio (LMR) operators have begun transitioning from circuit- switched to packet-switched backbone networks to handle their future communication needs. Due to the unique demands of packet-switched backbone networks for LMR, it may not be wise to carry over the previously implemented security methods used with circuit-switch systems or to treat an LMR backbone as a regular packet-switched network. This thesis investigates security in packet-switched LMR backbone networks to identify security issues in packet-switched LMR networks and provide possible solutions for them. Security solutions that are examined include different types of virtual private networks (VPNs), various encryption and keying procedures for safe communication, and logic behind how and where to implement security functions within the network. Specific schemes examined include IP Security (IPSec), OpenVPN, Virtual Tunnel (VTun), and Zebedee. I also present a quantitative analysis of the effects that the solutions have on packet-switched networks, in terms of link utilization, and on voice traffic, in terms of delay and delay jitter. -

Comparison of Virtual Networks Solutions for Community Clouds
KTH Royal Institute of Technology Bachelor Thesis Comparison of Virtual Networks Solutions for Community Clouds Examiner: Vladimir Vlassov Author: Albert Avellana Supervisors: Paris Carbone, Hooman Peiro Information and Communication Technology School February 2014 KTH Royal Institute of Technology Abstract Information and Communication Technology School Bachelor Thesis Comparison of Virtual Networks Solutions for Community Clouds by Albert Avellana Cloud computing has a huge importance and big impact nowadays on the IT world. The idea of community clouds has emerged recently in order to satisfy several user expectations. Clommunity is a European project that aims to provide a design and implementation of a self-configured, fully distributed, decentralized, scalable and robust cloud for a community of users across a commmunity network. One of the aspects to analyze in this design is which kind of Virtual Private Network (VPN) is going to be used to interconnect the nodes of the community members interested in access cloud services. In this thesis we will study, compare and analyze the possibility of using Tinc, IPOP or SDN-based solutions such as OpenFlow to establish such a VPN. Acknowledgements I would like to express my gratitude to all those who gave me the possibility to do this thesis in KTH. Firstly, I would like to thank Vlad for the opportunity he gave me to do this thesis and for his support. Secondly, thanks to my thesis supervisors: Paris Carbone and Hooman Peiro, who guided me through the research, helped me and gave me recommendations during this period. Also, I would like to thank F´elixFreitag and Leandro Navarro from Universitat Polit`ecnica de Catalunya for supporting me from Barcelona and make this stay in Stockholm possi- ble. -

Wireless LAN Security : IEEE 802.11G &
Volume 4, Issue 2, February 2014 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com Wireless LAN Security : IEEE 802.11g & VPN Abu Taha Zamani, Javed Ahmad Research Scholar, Techno Global University, Shillong, Meghalaya, India Abstract: 802.11g is an exciting new technology that offers additional performance, while providing investment protection for 802.11b clients through backward compatibility. By using previous technologies and economies of scale, 802.11g devices are available at little or no additional cost relative to 802.11b. As such, there are many reasons to begin migrating from 802.11b to 802.11g.802.11g is not, however, a panacea for WLAN capacity issues. As WLAN capacity needs increase, network professionals are well-advised to begin deploying a dual-band infrastructure to access the far greater capacity available with 802.11a. As such, 802.11g should be viewed as a portion of an overall WLAN architecture, not a substitute for 802.11a. 802.11g is a "bridge" technology and an ideal means for migrating from low-capacity 802.11b networks to the high-capacity, dual-band WLANs of the very near future. The evolution of wireless networking in recent years has raised many serious security issues. These security issues are of great concern for this technology as it is being subjected to numerous attacks. Because of the free-space radio transmission in wireless networks, eavesdropping becomes easy and consequently a security breach may result in unauthorized access, information theft, interference and service degradation. Virtual Private Networks (VPNs) have emerged as an important solution to security threats surrounding the use of public networks for private communications.
