Out-Of-Band Wormhole Attack Detection In Manets, Sana Ul Haq, Faisal B. Hussain Jan 2011

Out-Of-Band Wormhole Attack Detection In Manets, Sana Ul Haq, Faisal B. Hussain

Australian Information Security Management Conference

Mobile Ad hoc Networks (MANETs) are prone to a variety of attacks due to their unique characteristics such as dynamic topology, open wireless medium, absence of infrastructure, multi hop nature and resource constraints. Any node in mobile ad hoc networks operates not only as end terminal but both as an intermediate router and client. In this way, multi-hop communication occurs in MANETs and thus it is a difficult task to establish a secure path between source and destination. The purpose of this work is overcome a special attack called wormhole attack launched by at least two colluding nodes within the …

Trusted Interoperability And The Patient Safety Issues Of Parasitic Health Care Software, Vincent B. Mccauley, Patricia A H Williams

Australian Information Security Management Conference

With the proliferation of software systems and products in the healthcare environment, it is increasingly common for such software products to be constructed in a modular design. However, for modular software to be securely interoperable with other software products requires agreed consistent and accountable interfaces. This agreement may take the form of bilateral vendor to vendor arrangements or via a trusted external third-party who coordinates agreed interaction methods, such as a jurisdiction. Standards are a particular form of mutually trusted third party. Unfortunately, this agreed method of interoperability is not always present in vendor software. Where one software product or …

Australian Information Security Management Conference

The protection of patient information is now more important as a national e-health system approaches reality in Australia. The major challenge for health care providers is to understand the importance information security whilst also incorporating effective protection into established workflow and daily activity. Why then, when it is difficult for IT and security professionals to navigate through and apply the myriad of information security standards, do we expect small enterprises such as primary health care providers to also be able to do this. This is an onerous and impractical task without significant assistance. In the development of the new Computer …


Using Checklists To Make Better Best, Craig S. Wright, Tanveer A. Zia Jan 2011

Using Checklists To Make Better Best, Craig S. Wright, Tanveer A. Zia

Australian Information Security Management Conference

The more routine a task is we see the greater the need for a checklist. Even the smartest of us can forget where we parked our cars on returning from a long flight. So, the question is, why not create a straightforward checklist that will improve system management and security? In Information Technology operations, the vast majority of skilled people have re-built servers, but in an incident response situation, it can be unforgivable to overlook a serious security configuration simply because in the stress of the environment causes one to lose track of which stage they were on while being …

Source Code Embedded (Scem) Security Framework, Tanveer A. Zia, Aftab Rizvi

Australian Information Security Management Conference

Security in the Software Development Life Cycle (SDLC) has become imperative due to the variety of threats posed during and after system design. In this paper we have studied the security in system design in general and software development in particular, and have proposed strategies for integration of security in the SDLC. The paper highlights the needs of embedding security right from the earlier processes in the SDLC because patches and controls after the software delivery are more expensive to fix. We propose Source Code EMbedded (SCEM) security framework to improve the design of security policies and standards for the …


Seeing The Full Picture: The Case For Extending Security Ceremony Analysis, Giampaolo Bella, Lizzie Coles-Kemp Jan 2011

Seeing The Full Picture: The Case For Extending Security Ceremony Analysis, Giampaolo Bella, Lizzie Coles-Kemp

Australian Information Security Management Conference

The concept of the security ceremony was introduced a few years ago to complement the concept of the security protocol with everything about the context in which a protocol is run. In particular, such context involves the human executors of a protocol. When including human actors, human protocols become the focus, hence the concept of the security ceremony can be seen as part of the domain of socio-technical studies. This paper addresses the problem of ceremony analysis lacking the full view of human protocols. This paper categorises existing security ceremony analysis work and illustrates how the ceremony picture could be …


Designing Cyber Warfare Information Infrastructure Resilience, Semir Daskapan, Jan Van Der Berg Jan 2011

Designing Cyber Warfare Information Infrastructure Resilience, Semir Daskapan, Jan Van Der Berg

Australian Information Warfare and Security Conference

Due to many cyber attacks in the last years, governments are realizing how vulnerable they have become should there be a break out of a cyberwar. This urged them to establish a cyber warfare information infrastructure in a short time. However, this cyber warfare information infrastructure relies heavily on public infrastructures, like electricity and the Internet, which will be most likely targeted themselves. Therefore, a cyber warfare information infrastructure is by definition a vulnerable infrastructure that needs to be secured against attacks and made resilient. In this paper, we provide a method inspired by the theory of Complex Adaptive Systems …

Column: Every Last Byte, Simson Garfinkel

Journal of Digital Forensics, Security and Law

Inheritance powder is the name that was given to poisons, especially arsenic, that were commonly used in the 17th and early 18th centuries to hasten the death of the elderly. For most of the 17th century, arsenic was deadly but undetectable, making it nearly impossible to prove that someone had been poisoned. The first arsenic test produced a gas—hardly something that a scientist could show to a judge. Faced with a growing epidemic of poisonings, doctors and chemists spent decades searching for something better

Technology Corner: Brute Force Password Generation -- Basic Iterative And Recursive Algorithms, Nick V. Flor, Haile Shannon

Journal of Digital Forensics, Security and Law

Most information systems are secured at minimum by some form of password protection. For various reasons a password may be unavailable, requiring some form of password recovery procedure. One such procedure is software-based automated password recovery, where a program attempts to log into a system by repeatedly trying different password combinations. At the core of such software is a password generator. This article describes the basic iterative and recursive algorithms for generating all possible passwords of a given length, which is commonly referred to as brute-force password generation. The paper ends with a discussion of alternative password recovery procedures one …


Identity-Based Strong Designated Verifier Signature Revisited, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo Jan 2011

Identity-Based Strong Designated Verifier Signature Revisited, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo

Research Collection School Of Computing and Information Systems

Designated verifier signature (DVS) allows the signer to persuade a verifier the validity of a statement but prevent the verifier from transferring the conviction. Strong designated verifier signature (SDVS) is a variant of DVS, which only allows the verifier to privately check the validity of the signer’s signature. In this work we observe that the unforgeability model considered in the existing identity-based SDVS schemes is not strong enough to capture practical attacks, and propose to consider another model which is shown to be strictly stronger than the old one. We then propose a new efficient construction of identity-based SDVS scheme, …
