Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide. The growing significance of computer security reflects the increasing dependence on computer systems, the Internet, and evolving wireless network standards. This reliance has expanded with the proliferation of smart devices, including smartphones, televisions, and other components o…

Security information and event management (SIEM) is a field within computer security that combines security information management (SIM) and security event management (SEM) to enable real-time analysis of security alerts generated by applications and network hardware. SIEM systems are central to security operations centers (SOCs), where they are employed to detect, investigate, and respond to security incidents. SIEM technology collects and aggregates data from various systems, allowing organizations to meet compliance requirements while safeguarding against threats. NIST's definition for a SIEM tool is an application that provides the ability to gather security data from information system…

Information security (infosec) is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible (e.g., paperwork), or intangible (e.g., knowledge). Information security's primary focus is the balanced protection of data confidentiality, in…

Comprehensive security review and challenges for smart and power grids to prevent cyber-attacks in IoTs.. One of the most significant use cases of the Internet of Things (IoTs) is the Smart Grid (SG), which is an advanced digital bi-directional power distribution system characterized by self-recovery capabilities. This SG offers resilient, adaptive, self-recovery, and sustainable power distribution. The recent past has seen a gradual shift from unidirectional power systems towards the SG's bi-directional model. However, these large, complex, and self-healing SG systems have numerous vulnerabilities that threaten the exchanged data and power control commands. Therefore, many research efforts…

Authentication Mechanisms in the Internet of Things: A Comparative Analysis Across RFID, Smart Grids, Vehicular Networks, and Smart Homes.. The Internet of Things (IoT) is envisioned to link billions of diverse devices together. To safeguard privacy of user data, ensure authenticity of the data communicated between these devices, and guarantee their availability, robust authentication is needed. On the other hand, authentication techniques face several security challenges because IoT devices are resource-constrained (memory, battery, processor, etc.). To elaborate on this, we perform an extensive survey of authentication mechanisms in IoT, addressing the resource-constrained nature of devic…

Digital data or digital information, in information theory and information systems, is data or information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters. The most common form of digital data in modern information systems is binary data, which is represented by a string of binary digits (bits) each of which can have one of two values, either 0 or 1. Digital data can be contrasted with analog data, which is represented by a value from a continuous range of real numbers. Analog data is transmitted by a…

A systematic literature review of cyber-security data repositories and performance assessment metrics for semi-supervised learning.. In Machine Learning, the datasets used to build models are one of the main factors limiting what these models can achieve and how good their predictive performance is. Machine Learning applications for cyber-security or computer security are numerous including cyber threat mitigation and security infrastructure enhancement through pattern recognition, real-time attack detection, and in-depth penetration testing. Therefore, for these applications in particular, the datasets used to build the models must be carefully thought to be representative of real-world da…

Robotic systems in internet of things: addressing security challenges through threat modeling and penetration testing.. The increasing prevalence of robotic systems across diverse domains has undoubtedly delivered numerous advantages. However, this proliferation has also exposed these systems to potential security threats, with the ability to cause significant human and financial losses. In this study we propose a proactive approach to risk management using threat modeling techniques. This approach provides a systematic framework for risk assessment, facilitating the identification and prioritization of the most severe threats for possible mitigation. Specifically, we provide Attack-Defense…
