A Review on Cloud Data Security Challenges and existing Countermeasures in Cloud Computing

Cloud computing (CC) is among the most rapidly evolving computer technologies. That is the required accessibility of network assets, mainly information storage with processing authority without the requirement for particular and direct user administration. CC is a collection of public and private data centers that provide a single platform for clients throughout the Internet. The growing volume of personal and sensitive information acquired through supervisory authorities demands the usage of the cloud not just for information storage and for data processing at cloud assets. Nevertheless, due to safety issues raised by recent data leaks, it is recommended that unprotected sensitive data not be sent to public clouds. This document provides a detailed appraisal of the research regarding data protection and privacy problems, data encrypting, and data obfuscation, including remedies for cloud data storage. The most up-to-date technologies and approaches for cloud data security are examined. This research also examines several current strategies for addressing cloud security concerns. The performance of each approach is then compared based on its characteristics, benefits, and shortcomings. Finally, go at a few active cloud storage data security study fields

Post-Quantum Era Privacy Protection for Intelligent Infrastructures

As we move into a new decade, the global world of Intelligent Infrastructure (II) services integrated into the Internet of Things (IoT) are at the forefront of technological advancements. With billions of connected devices spanning continents through interconnected networks, security and privacy protection techniques for the emerging II services become a paramount concern. In this paper, an up-to-date privacy method mapping and relevant use cases are surveyed for II services. Particularly, we emphasize on post-quantum cryptography techniques that may (or must when quantum computers become a reality) be used in the future through concrete products, pilots, and projects. The topics presented in this paper are of utmost importance as (1) several recent regulations such as Europe's General Data Protection Regulation (GDPR) have given privacy a significant place in digital society, and (2) the increase of IoT/II applications and digital services with growing data collection capabilities are introducing new threats and risks on citizens' privacy. This in-depth survey begins with an overview of security and privacy threats in IoT/IIs. Next, we summarize some selected Privacy-Enhancing Technologies (PETs) suitable for privacy-concerned II services, and then map recent PET schemes based on post-quantum cryptographic primitives which are capable of withstanding quantum computing attacks. This paper also overviews how PETs can be deployed in practical use cases in the scope of IoT/IIs, and maps some current projects, pilots, and products that deal with PETs. A practical case study on the Internet of Vehicles (IoV) is presented to demonstrate how PETs can be applied in reality. Finally, we discuss the main challenges with respect to current PETs and highlight some future directions for developing their post-quantum counterparts

Data privacy, security and trust in "consumer internet of things" assemblages and associated mobile applications in South Africa

The Internet of Things (IoT) brings with it opportunities and challenges. IoT technology makes it possible to connect all of a person’s devices to create a smart eco-system or assemblage. Various stakeholders share personal data with companies in the consumer IoT space for marketing, tracking and assessment of the IoT products. In a world where cybercriminals have increased enormously, people need to be aware of the advantages, and the risks that come with these technological advances. The purpose of this study was to explore the data privacy, security and trust issues faced by consumers of IoT in South Africa, to propose an integrated and holistic framework that promotes safer adoption of consumer Internet of Things (CIoT). The researcher explained the difference between Industrial IoT (IIoT) and consumer CIoT in the study and focused the research on the latter. This study utilized a qualitative narrative inquiry and Delphi technique to explore the challenges that come with CIoT assemblages and associated mobile applications in South Africa. The researcher’s original contribution was to develop a holistic framework that all stakeholders may use to protect consumers of IoT. The proposed framework addresses the challenges of CIoT from a legal, technical and social context viewpoint. The study looked at legal instruments around the world and compared them to the South African existing legal instruments. The researcher established that South Africa has various pieces of legislation such as the Protection of Personal Information Act 4 of 2013, the Consumer Protection Act 68 of 2008, the Electronic Communications Act 36 of 2005, and the Electronic Communications and Transactions Act 25 of 2002, that law enforcers may use to deal with the challenges IoT. However, the researcher ascertained that these laws do not necessarily address IoT specifically as they are; in fact, they are either outdated or fragmented. In addition to the background literature, the research sought expert opinions to address the technical viewpoints of the CIoT assemblage. The technical approach looked at the existing technologies, design and development considerations, and the overall architecture of CIoT. The researcher generated theme and sub-themes using thematic analysis. There main themes were regarding regulatory frameworks, privacy of personal information, security concerns, trust issues, and convenience and benefits. The study further established that consumers enjoy the convenience and benefits that IoT technology brings. The study suggested an integrated and holistic framework that promote safer adoption of CIoT and associated mobile apps. The conclusion is that for CIoT to thrive, safety is crucial, and all the stakeholders in the IoT assemblage need to ensure the protection of consumers. The suggested framework may assist in the protection of consumers of IoT. The researcher recommends a further study that covers the regulators such as ICASA in detail and the enforcement of the POPI Act.Information ScienceD. Phil (Information Science
