Why Penetration Testing Is A Limited Use Choice For Sound Cyber Security Practice, Craig Valli, Andrew J. Woodward, Peter Hannay, Michael N. Johnstone

Research outputs 2014 to 2021

Penetration testing of networks is a process that is overused when demonstrating or evaluating the cyber security posture of an organisation. Most penetration testing is not aligned with the actual intent of the testing, but rather is driven by a management directive of wanting to be seen to be addressing the issue of cyber security. The use of penetration testing is commonly a reaction to an adverse audit outcome or as a result of being penetrated in the first place. Penetration testing used in this fashion delivers little or no value to the organisation being tested for a number of …

Privacy-Preserving Ad-Hoc Equi-Join On Outsourced Data, Hwee Hwa Pang, Xuhua Ding

Research Collection School Of Computing and Information Systems

In IT outsourcing, a user may delegate the data storage and query processing functions to a third-party server that is not completely trusted. This gives rise to the need to safeguard the privacy of the database as well as the user queries over it. In this article, we address the problem of running ad hoc equi-join queries directly on encrypted data in such a setting. Our contribution is the first solution that achieves constant complexity per pair of records that are evaluated for the join. After formalizing the privacy requirements pertaining to the database and user queries, we introduce a …

Click fraud - the deliberate clicking on advertisements with no real interest on the product or service offered - is one of the most daunting problems in online advertising. Building an elective fraud detection method is thus pivotal for online advertising businesses. We organized a Fraud Detection in Mobile Advertising (FDMA) 2012 Competition, opening the opportunity for participants to work on real-world fraud data from BuzzCity Pte. Ltd., a global mobile advertising company based in Singapore. In particular, the task is to identify fraudulent publishers who generate illegitimate clicks, and distinguish them from normal publishers. The competition was held from …

A Robust Smart Card-Based Anonymous User Authentication Protocol For Wireless Communications, Fengton Wen, Willy Susilo, Guomin Yang

Research Collection School Of Computing and Information Systems

Anonymous user authentication is an important but challenging task for wireless communications. In a recent paper, Das proposed a smart cardï based anonymous user authentication protocol for wireless communications. The scheme can protect user privacy and is believed to be secure against a range of network attacks even if the secret information stored in the smart card is compromised. In this paper, we reanalyze the security of Das' scheme, and show that the scheme is in fact insecure against impersonation attacks. We then propose a new smart cardï based anonymous user authentication protocol for wireless communications. Compared with the existing …

Cross-Domain Password-Based Authenticated Key Exchange Revisited, Liqun Chen, Hoon Wei Lim, Guomin Yang

Research Collection School Of Computing and Information Systems

We revisit the problem of secure cross-domain communication between two users belonging to different security domains within an open and distributed environment. Existing approaches presuppose that either the users are in possession of public key certificates issued by a trusted certificate authority (CA), or the associated domain authentication servers share a long-term secret key. In this article, we propose a generic framework for designing four-party password-based authenticated key exchange (4PAKE) protocols. Our framework takes a different approach from previous work. The users are not required to have public key certificates, but they simply reuse their login passwords, which they share …

On The Security Of Auditing Mechanisms For Secure Cloud Storage, Yong Yu, Lei Niu, Guomin Yang, Yi Mu, Willy Susilo

Research Collection School Of Computing and Information Systems

Cloud computing is a novel computing model that enables convenient and on-demand access to a shared pool of configurable computing resources. Auditing services are highly essential to make sure that the data is correctly hosted in the cloud. In this paper, we investigate the active adversary attacks in three auditing mechanisms for shared data in the cloud, including two identity privacy-preserving auditing mechanisms called Oruta and Knox, and a distributed storage integrity auditing mechanism.We show that these schemes become insecure when active adversaries are involved in the cloud storage. Specifically, an active adversary can arbitrarily alter the cloud data without …

Categorization Of Large Corpora Of Malicious Software, Deekshit Kura

LSU New Orleans Theses and Dissertations

Malware is computer software written by someone with mischievous or, more usually, malicious and/or criminal intent and specifically designed to damage data, hosts or networks. The variety of malware is increasing proportionally with the increase in computers and we are not aware of newly emerging malware. Tools are needed to categorize families of malware, so that analysts can compare new malware samples to ones that have been previously analyzed and determine steps to detect and prevent malware infections.

In this thesis, I developed a technique to catalog and characterize the behavior of malware, so that malware families, the level of …

A Conceptual Model For Federated Authentication In The Cloud, Abdulwahid Al Abdulwahid, Nathan Clarke, Steven Furnell, Ingo Stengel

Australian Information Security Management Conference

Authentication is a key security control for any computing system, whether that is a PC, server, laptop, tablet or mobile phone. However, authentication is traditionally poorly served, with existing implementations falling foul of a variety of weaknesses. Passwords are poorly selected, reused and shared (to name but a few). Research has suggested novel approaches to authentication such as transparent authentication and cooperative and distributed authentication. However, these technologies merely focus upon individual platforms rather than providing a universal and federated authentication approach that can be used across technologies and services. The advent of cloud computing, its universal connectivity, scalability and …

The Effectiveness Of Internet Activity Erasure Tools To Protect Privacy, Brian Cusack, Andrew Woodward, Scott Butson, Benjamin Leber

Australian Information Security Management Conference

When most people go to the trouble of getting erasure tools to remove data from their hard drives they expect the job is done correctly. Using erasure tools is a step to protect privacy by assuming the applied tools erase data rather than simply delete data that may be recovered using forensic tools. In this research we tested the performance of the delete function on three web browsers against the performance of eight erasure tools with alarming results. It was found that the erasure tools had almost the same capability to delete data as the web browsers delete function; and …

Exchanging Demands: Weaknesses In Ssl Implementations For Mobile Platforms, Peter Hannay, Clinton Carpene, Craig Valli, Andrew Woodward, Mike Johnstone

Australian Information Security Management Conference

The ActiveSync protocol’s implementation on some embedded devices leaves clients vulnerable to unauthorised remote policy enforcement. This paper discusses a proof of concept attack against the implementation of ActiveSync in common Smart phones including Android devices and iOS devices. A two‐phase approach to exploiting the ActiveSync protocol is introduced. Phase 1 details the usage of a man‐in‐the‐middle attack to gain a vantage point over the client device, whilst Phase 2 involves spoofing the server‐side ActiveSync responses to initiate the unauthorised policy enforcement. These vulnerabilities are demonstrated by experiment, highlighting how the system can be exploited to perform a remote factory …

A Simulation-Based Study Of Server Location Selection Rules In Manets Utilising Threshold Cryptography, Alastair Nisbet

Australian Information Security Management Conference

Truly Ad Hoc wireless networks where a spontaneous formation of a network occurs and there is no prior knowledge of nodes to each other present significant security challenges, especially as entirely online configuration of nodes with encryption keys must be performed. Utilising threshold cryptography in this type of MANET can greatly increase the security by requiring servers to collaborate to form a single Certificate Authority (CA). In this type of CA responsibility for certificate services is shared between a threshold of servers, greatly increasing security and making attack against the CA considerably more difficult. Choosing which nodes to take on …

Australian Information Security Management Conference

Information Security (InfoSec) education varies in its content, focus and level of technicality across the world. In this paper we investigate the differences between graduate InfoSec programs in top universities in China and in the United States of America (USA). In China, curriculum emphasises Telecommunication, Computer Science and InfoSec Technology, whilst in the USA in addition to Computer Science and InfoSec Technology the curriculum also emphasises Enterprise‐level Security Strategy and Policy, InfoSec Management, and Cyber Law. The differences are significant and will have a profound impact on both the perceptions and capabilities of future generations of information security professionals on …

Information Security Management: Factors That Influence Security Investments In Smes, Zhi Xian Ng, Atif Ahmad, Sean B. Maynard

Australian Information Security Management Conference

In the modern information economy, the security of information is critically important to organizations. Information‐security risk assessments (ISRAs) allow organizations to identify key information assets and security risks so security expenditure can be directed cost‐effectively. Unfortunately conducting ISRAs requires special expertise and tends to be complex and costly for small to medium sized organizations (SMEs). Therefore, it remains unclear in practice, and unknown in literature, how SMEs address information security imperatives without the benefit of an ISRA process. This research makes a contribution to theory in security management by identifying the factors that influence key decision-makers in SMEs to address …

Determining What Characteristics Constitute A Darknet, Symon Aked, Christopher Bolan, Murray Brand

Australian Information Security Management Conference

Privacy on the Internet has always been a concern, but monitoring of content by both private corporations and Government departments has pushed people to search for ways to communicate over the Internet in a more secure manner. This has given rise to the creations of Darknets, which are networks that operate “inside” the Internet, and allow anonymous participation via a de‐centralised, encrypted, peer‐to‐peer network topology. This research investigates some sources of known Internet content monitoring, and how they provided the template for the creation of a system to avoid such surveillance. It then highlights how communications on the Clearnet is …

Australian Information Security Management Conference

This research examines the current level of security in wireless networks in New Zealand. A comprehensive wardrive covering the length of the country was made in January 2013 to ensure accurate comparisons from two previous wardrives as well as comparisons between the four main cities and the suburbs can be made. With 16 years since the introduction of the original IEEE 802.11 wireless standard having passed, an examination is made of the current state of wireless security of networks throughout New Zealand and the Auckland suburbs, and where possible compares these results with similar studies undertaken in 2004 and 2011. …

Usability And Security Support Offered Through Adsl Router User Manuals, Patryk Szewczyk

Australian Information Security Management Conference

ADSL routers are often used as either the target or the means for cyber crime. Many ADSL router threats could be mitigated through the effective use of inbuilt security controls and firmware updates available from vendors. Unfortunately, end‐users typically lack the technical expertise to correctly configure and secure the device. Subsequently, end‐users are reliant on well documented procedures provided by vendors in their user manuals and quick start guides. This study investigates the usability and security recommendations and encouragements put forth by vendors in their user manuals. The study demonstrates that user manual usability does not conform to ideal technical …

Efficient Routing For Wireless Mesh Networks Using A Backup Path, Amir Esmailpour, Nidal Nasser, Jehad Al Dallal

Electrical & Computer Engineering and Computer Science Faculty Publications

Wireless Mesh Network (WMN) has a proven record in providing viable solutions for some of the fundamental issues in wireless networks such as capacity and range limitations. WMN infrastructure includes clusters of Mobile Ad-Hoc Networks (MANETs) connected through a fixed backbone of mesh routers. The mesh network can be constrained severely due to various reasons, which could result in performance degradation such as a drop in throughput or long delays. Solutions to this problem often focus on multipath or multichannel extensions to the existing ad- hoc routing protocols. In this paper, we propose a novel solution by introducing an alternative …

Group Selection And Key Management Strategies For Ciphertext-Policy Attribute-Based Encryption, Russell F. Martin

Theses

Ciphertext-Policy Attribute-Based Encryption (CPABE) was introduced by Bethencourt, Sahai, and Waters, as an improvement of Identity Based Encryption, allowing fine grained control of access to encrypted files by restricting access to only users whose attributes match that of the monotonic access tree of the encrypted file. Through these modifications, encrypted files can be placed securely on an unsecure server, without fear of malicious users being able to access the files, while allowing each user to have a unique key, reducing the vulnerabilites associated with sharing a key between multiple users.

However, due to the fact that CPABE was designed for …

Towards A Hybrid Framework For Detecting Input Manipulation Vulnerabilities, Sun Ding, Hee Beng Kuan Tan, Lwin Khin Shar, Bindu Madhavi Padmanabhuni

Research Collection School Of Computing and Information Systems

Input manipulation vulnerabilities such as SQL Injection, Cross-site scripting, Buffer Overflow vulnerabilities are highly prevalent and pose critical security risks. As a result, many methods have been proposed to apply static analysis, dynamic analysis or a combination of them, to detect such security vulnerabilities. Most of the existing methods classify vulnerabilities into safe and unsafe. They have both false-positive and false-negative cases. In general, security vulnerability can be classified into three cases: (1) provable safe, (2) provable unsafe, (3) unsure. In this paper, we propose a hybrid framework-Detecting Input Manipulation Vulnerabilities (DIMV), to verify the adequacy of security vulnerability defenses …

With the new technologies and new techniques, the attackers are finding more sophisticated ways to attack the servers. In this situation, it is necessary to come up with various mechanisms to detect and defend these DDoS attacks and protect the servers from the attackers. Many researches have been carried out to detect the DDoS attack traffic in transport layer, which is more vulnerable to DDoS …

Application Of Ntru Cryptographic Algorithm For Securing Scada Communication, Amritha Puliadi Premnath

UNLV Theses, Dissertations, Professional Papers, and Capstones

Supervisory Control and Data Acquisition (SCADA) system is a control system which is widely used in Critical Infrastructure System to monitor and control industrial processes autonomously. Most of the SCADA communication protocols are vulnerable to various types of cyber-related attacks. The currently used security standards for SCADA communication specify the use of asymmetric cryptographic algorithms like RSA or ECC for securing SCADA communications. There are certain performance issues with cryptographic solutions of these specifications when applied to SCADA system with real-time constraints and hardware limitations. To overcome this issue, in this thesis we propose the use of a faster and …

A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fengtong Wen, Willy Susilo, Guomin Yang

Research Collection School Of Computing and Information Systems

In global mobility networks, anonymous user authentication is an essential task for enabling roaming service. In a recent paper, Jiang et al. proposed a smart card based anonymous user authentication scheme for roaming service in global mobility networks. This scheme can protect user privacy and is believed to have many abilities to resist a range of network attacks, even if the secret information stored in the smart card is compromised. In this paper, we analyze the security of Jiang et al.’s scheme, and show that the scheme is in fact insecure against the stolen-verifier attack and replay attack. Then, we …
