Using Passive And Active Enumeration Methods To Improve Ipv6 Host Enumeration Search Algorithms, Clinton Carpene
Using Passive And Active Enumeration Methods To Improve Ipv6 Host Enumeration Search Algorithms, Clinton Carpene
Australian Information Security Management Conference
IPv6 off-link host enumeration, when compared to IPv4 host enumeration, is a difficult and expensive exercise. The expense arises from the difference in address space sizes between the two protocols, with IPv6 having a 296 larger address space than that of IPv4. This paper presents an algorithm for performing contextual IPv6 host enumeration against a target. The algorithm uses passive and active enumeration in order to focus the search upon areas of the address space where it is more probable that targets will exist. Experiments were conducted to test the proposed adaptive heuristic search algorithm involving applying the algorithm to …

A Survey Of Ipv6 Address Usage In The Public Domain Name System, Clinton R. Carpene, Andrew Woodward
Australian Information Security Management Conference
The IPv6 protocol has been slowly increasing in use on the Internet. The main reason for the development of the protocol is that the address space provided by IPv4 is nearing exhaustion. The pool of addresses provided by IPv6 is 296 times larger than IPv4, and should be sufficient to provide an address for every device for the foreseeable future. Another potential advantage of this significantly large address space is the use of randomly assigned addresses as a security barrier as part of a defence in depth strategy. This research examined the addresses allocated by those implementing IPv6 to determine …
Evaluating The Security Vulenerabilities Of The Ip6to4 Tunnelling Mechanism, Brian Cusack, Raymond Lutui
Evaluating The Security Vulenerabilities Of The Ip6to4 Tunnelling Mechanism, Brian Cusack, Raymond Lutui
Australian Information Security Management Conference
The two versions of Internet Protocol (IP) rely on mechanisms that will convert one protocol to the other and vice versa. Version 4 is still prevalent in the Internet backbone and version 6 in most private networks. In this research we focus on the automatic tunnelling mechanism that provides the encapsulation at one end of the transition tunnel and the de-encapsulation at the other end dependant on the direction of transition. In our research we asked: How secure is the automatic tunnelling mechanism? It is a simple question but important given the number of times transition may occur in any …
Exposing Potential Privacy Issues With Ipv6 Address Construction, Clinton Carpene, Andrew Woodward
Exposing Potential Privacy Issues With Ipv6 Address Construction, Clinton Carpene, Andrew Woodward
Australian Information Security Management Conference
The usage of 128 bit addresses with hexadecimal representation in IPv6 poses significant potential privacy issues. This paper discusses the means of allocating IPv6 addresses, along with the implications each method may have upon privacy in different usage scenarios. The division of address space amongst the global registries in a hierarchal fashion can provide geographical information about the location of an address, and its originating device. Many IPv6 address configuration methods are available, including DHCPv6, SLAAC (with or without privacy extensions), and Manual assignment. These assignment techniques are dissected to expose the identifying characteristics of each technique. It is seen …
