Online Privacy Challenges And Their Forensic Solutions, Bandr Fakiha Jun 2022

Online Privacy Challenges And Their Forensic Solutions, Bandr Fakiha

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

In the digital age, internet users are exposed to privacy issues online. Few rarely know when someone else is eavesdropping or about to scam them. Companies, governments, and individual internet users are all vulnerable to security breaches due to the challenges of online privacy ranging from trust and hierarchical control to financial losses. As systems advance, people are optimistic that forensic science will provide long-term interventions that surpass the current solutions, including setting stronger passwords and firewall protection. The future of online privacy is changing, and more practical interventions, such as email, malware, mobile, and network forensics, must be integrated, …


Towards Practicalization Of Blockchain-Based Decentralized Applications, Songlin He May 2022

Towards Practicalization Of Blockchain-Based Decentralized Applications, Songlin He

Dissertations

Blockchain can be defined as an immutable ledger for recording transactions, maintained in a distributed network of mutually untrusting peers. Blockchain technology has been widely applied to various fields beyond its initial usage of cryptocurrency. However, blockchain itself is insufficient to meet all the desired security or efficiency requirements for diversified application scenarios. This dissertation focuses on two core functionalities that blockchain provides, i.e., robust storage and reliable computation. Three concrete application scenarios including Internet of Things (IoT), cybersecurity management (CSM), and peer-to-peer (P2P) content delivery network (CDN) are utilized to elaborate the general design principles for these two main …


Rhetsec_ | Rhetorical Security, Jennifer Mead Dec 2019

Rhetsec_ | Rhetorical Security, Jennifer Mead

Culminating Projects in English

Rhetsec_ examines the rhetorical situation, the rhetorical appeals, and how phishing emails simulate "real" emails in five categories of phishing emails. While the first focus of cybersecurity is security, you must also understand the language of computers to know how to secure them. Phishing is one way to compromise security using computers, and so the computer becomes a tool for malicious language (phishing emails and malware) to be transmitted. Therefore to be concerned with securing computers, then you must also be concerned with language. Language is rhetoric's domain, and the various rhetorical elements which create an identity of the phisher …


Web Application Penetration Testing, Besnik Qehaja, Gazmend Krasniqi, Ardian Bajraliu, Amet Shabani Oct 2016

Web Application Penetration Testing, Besnik Qehaja, Gazmend Krasniqi, Ardian Bajraliu, Amet Shabani

UBT International Conference

Safety of information is needed either in private sector or business for protection from market with competitive secrets or only for privacy. Advantages of internet and web applications is that they are accessible from everyone, but in business word data should be safe, reliable accessible. Although these are not new problems and always had different solutions to these problems, we always need to be on the cutting edge with new attacks that appear every day and to try to achieve a greater security. In this paper we present some of the most dangerous forms of risk which are risking web …


A Survey Of Social Media Users Privacy Settings & Information Disclosure, Mashael Aljohani, Alastair Nisbet, Kelly Blincoe Jan 2016

A Survey Of Social Media Users Privacy Settings & Information Disclosure, Mashael Aljohani, Alastair Nisbet, Kelly Blincoe

Australian Information Security Management Conference

This research utilises a comprehensive survey to ascertain the level of social networking site personal information disclosure by members at the time of joining the membership and their subsequent postings to the sites. Areas examined are the type of information they reveal, their level of knowledge and awareness regarding how their information is protected by SNSs and the awareness of risks that over-sharing may pose. Additionally, this research studies the effect of gender, age, education, and level of privacy concern on the amount and kind of personal information disclosure and privacy settings applied. A social experiment was then run for …


Empirical Analysis Of Socio-Cognitive Factors Affecting Security Behaviors And Practices Of Smartphone Users, Joseph P. Simpson Jan 2016

Empirical Analysis Of Socio-Cognitive Factors Affecting Security Behaviors And Practices Of Smartphone Users, Joseph P. Simpson

CCE Theses and Dissertations

The overall security posture of information systems (IS) depends on the behaviors of the IS users. Several studies have shown that users are the greatest vulnerability to IS security. The proliferation of smartphones is introducing an entirely new set of risks, threats, and vulnerabilities. Smartphone devices amplify this data exposure problem by enabling instantaneous transmission and storage of personally identifiable information (PII) by smartphone users, which is becoming a major security risk. Moreover, companies are also capitalizing on the availability and powerful computing capabilities of these smartphone devices and developing a bring-your-own-device (BYOD) program, which makes companies susceptible to divulgence …


Using Graphic Methods To Challenge Cryptographic Performance, Brian Cusack, Erin Chapman Jan 2016

Using Graphic Methods To Challenge Cryptographic Performance, Brian Cusack, Erin Chapman

Australian Information Security Management Conference

Block and stream ciphers have formed the traditional basis for the standardisation of commercial ciphers in the DES, AES, RC4, and so on. More recently alternative graphic methods such as Elliptic Curve Cryptography (ECC) have been adopted for performance gains. In this research we reviewed a range of graphic and non-graphic methods and then designed our own cipher system based on several graphic methods, including Visual Cryptography (VC). We then tested our cipher against RC4 and the AES algorithms for performance and security. The results showed that a graphics based construct may deliver comparable or improved security and performance in …

Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo Apr 2011

Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo

All Faculty Scholarship

Cloud computing has emerged as perhaps the hottest development in information technology. Despite all of the attention that it has garnered, existing analyses focus almost exclusively on the issues that surround data privacy without exploring cloud computing’s architectural and policy implications. This article offers an initial exploratory analysis in that direction. It begins by introducing key cloud computing concepts, such as service-oriented architectures, thin clients, and virtualization, and discusses the leading delivery models and deployment strategies that are being pursued by cloud computing providers. It next analyzes the economics of cloud computing in terms of reducing costs, transforming capital expenditures …


Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko May 2004

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko

Pr. Mamoudou H. DICKO, PhD

The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …
