Status of Open Source and Commercial Ipv6 Firewall Implementations (Paper)
Status of Open Source and commercial IPv6 firewall implementations Dr. Peter Bieringer AERAsec Network Services & Security GmbH [email protected] http://www.aerasec.de/ European Conference on Applied IPv6 (ECAI6) Cologne, Germany September 6 - 7, 2007 Abstract IPv6, the successor of IPv4, has been ready for production for quite some time. For security reason, firewalling in IPv6 is also an important requirement. This paper presents an overview of the status of Open Source and commer- cial implementations. Introduction With IPv4 nowadays, many client-to-server and most client-to-client communications are intercepted by gate- ways with address and port masquerading abilities, usually named Network (and Port) Address Translation (NAT, NAPT). This prohibits native client-to-client communication, if both peers are located behind such gate- ways. In this case, only special tunnelling techniques, like STUN (Simple traversal of UDP over NATs), which requires special servers located at the Internet, or other ªfirewall-piercingº methods can help to establish native and bidirectional client-to-client communication. One of the goals of IPv6 is the re-introduction of bidirectional, native end-to-end communication without play- ing any tricks on gateways in between. Also, IPv6 has a large enough address space which should suffice for the next decades. Therefore NAT was left out by design, too. Jumping back to IPv4, the initial intention of introducing NAT was the lack of IPv4 addresses for use in internal networks, while still allowing clients to open connections to the Internet via a hiding mechanism. It turned out to also protect internal networks against threats from the Internet, because under normal circumstances (bug- free stateful hiding-NAT implementation on the gateway) it©s not possible for an outside node to connect to an internal host without any dedicated rule on the gateway. -

COMPARATIVE ANALYSIS OF PACKET SNIFFERS : A STUDY Jyoti Senior Engineer, Bharat Electronics Limited (India) ABSTRACT Today everything is being centralized through a common dedicated network to ease its use, make it more user friendly and increase its efficiency. The size of these centric networks is also increasing rapidly. So the management, maintenance and monitoring of these networks is important to keep network smooth and improve economic efficiency. Packet sniffing or packet analysis is the process of capturing data passed over the local network and looking for any information that may be useful. There is a wide variety of packet sniffers available in the market that can be exploited for this purpose. This paper focuses on the basics of packet sniffer, its working principle and a comparative study of various packet sniffers. Keywords: Packet Capture; Packet Sniffer; network monitoring; wireshark; NIC I INTRODUCTION A packet sniffer is a program that can see all of the information passing over the network it is connected to. As data steams back and forth on the network the program looks at it or „sniffs‟ each packet. A packet is a part of a message that has been broken up. Packet analysis can help us understand network characteristics, learn who is on network, determine who or what is utilizing available bandwidth, identify peak network usage times, identify possible attacks or malicious activity, and find unsecured and bloated applications[1]. II WORKING There are two modes in which a network interface of a machine work i.e Promiscuous and Non-promiscuous. Promiscuous mode in one in which the NIC of the machine can take over all packets and a frame it receives on network, namely this machine (involving its software) is sniffer. -
IMPLEMENTATION, EVALUATION, and APPLICATIONS of MOBILE MESH NETWORKS for PLATFORMS in MOTION Jared
ABSTRACT Title of Document: IMPLEMENTATION, EVALUATION, AND APPLICATIONS OF MOBILE MESH NETWORKS FOR PLATFORMS IN MOTION Jared Stanislaus Napora Master of Science, 2009 Directed By: Professor Christopher C. Davis Department of Electrical and Computer Engineering This thesis explores the selection, implementation, and evaluation of two mobile mesh networks, each involving a different distributed computing problem. In the forthcoming discussion, it will become apparent how system constraints affect the optimal choice of mesh networking design and implementation in these cases. The first problem explores the design and implementation of a distributed computing mesh network that will allow a collection of autonomous land vehicles to gather, process, and exchange information in an unknown environment. This network was established by adapting standard commercial 802.11 routers and by providing a software framework that handles all communication between wireless nodes. The second problem involves the design of a network for tracking and monitoring personnel. This network was implemented utilizing ZigBee modules due to power and custom implementation constraints. Both networks were tested with respect to their specific design constraints and they lay the foundation for additional application development and research. IMPLEMENTATION, EVALUATION, AND APPLICATIONS OF MOBILE MESH NETWORKS FOR PLATFORMS IN MOTION By Jared Stanislaus Napora Thesis submitted to the Faculty of the Graduate School of the University of Maryland, College Park, in partial fulfillment of the requirements for the degree of Master of Science 2009 Advisory Committee: Professor Christopher C.

Wifi drivers often have serious bugs that pose a security threat. By being able to modify the firmware, users are able to defend their network and data from malicious hackers and criminals. Americans should have the right to maintain their security. In addition, allowing modification allows researchers and other inventors to create new innovation that would make computing and wireless data transfer more secure, which would reduce the costs of damages that security issues cause. Not fixing security holes either feeds cyberthreats or increases electronic waste. Meanwhile,there is no evidence that open-source firmware has caused any more wireless interference than closed-source firmware. Please do not implement restrictions that hinder progress and security. Implementing rules that take away the ability of users to install the software of their choosing on their computing devices reduces innovation and security.
