Cybersecurity
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of 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 from the disruption or misdirection of the services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societies they support. Security is particularly crucial for systems that govern large-scale sy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Election Security
Election cybersecurity or election security refers to the protection of elections and voting infrastructure from cyberattack or cyber threat – including the tampering with or infiltration of voting machines and equipment, election office networks and practices, and voter registration databases. Cyber threats or attacks to elections or voting infrastructure could be carried out by insiders within a voting jurisdiction, or by a variety of other actors ranging from nefarious nation-states, to organized cyber criminals to lone-wolf hackers. Motives may range from a desire to influence the election outcome, to discrediting democratic processes, to creating public distrust or even political upheaval. Legislation and policy best practices A variety of experts and interest groups have emerged to address voting infrastructure vulnerabilities and to support democracies in their security efforts. From these efforts have come a general set of policy ideas for election security, includ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Security Convergence
Security convergence refers to the convergence of two historically distinct security functions – physical security and information security – within enterprises; both are integral parts of a coherent risk management program. Security convergence is motivated by the recognition that corporate assets are increasingly information-based. In the past, physical assets demanded the bulk of protection efforts, whereas information assets are demanding increasing attention. Although generally used in relation to cyber-physical convergence, security convergence can also refer to the convergence of security with related risk and resilience disciplines, including business continuity planning and emergency management. Security convergence is often referred to as 'converged security'. Definitions According to the United States Cybersecurity and Infrastructure Security Agency, security convergence is the "formal collaboration between previously disjointed security functions."

Internet Of Things
Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The IoT encompasses Electronic engineering, electronics, Telecommunications engineering, communication, and computer science engineering. "Internet of things" has been considered a misnomer because devices do not need to be connected to the public internet; they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, and increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022. .

Encryption
In Cryptography law, cryptography, encryption (more specifically, Code, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption Key (cryptography), key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. Historically, various forms of encryption have been used to aid in cryptography. Early encryption ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cyberattack
A cyberattack (or cyber attack) occurs when there is an unauthorized action against computer infrastructure that compromises the confidentiality, integrity, or availability of its content. The rising dependence on increasingly complex and interconnected computer systems in most domains of life is the main factor that causes vulnerability to cyberattacks, since virtually all computer systems have bugs that can be exploited by attackers. Although it is impossible or impractical to create a perfectly secure system, there are many defense mechanisms that can make a system more difficult to attack, making information security a field of rapidly increasing importance in the world today. Perpetrators of a cyberattack can be criminals, hacktivists, or states. They attempt to find weaknesses in a system, exploit them and create malware to carry out their goals, and deliver it to the targeted system. Once installed, the malware can have a variety of effects depending on its purpose. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Information Security
Information security 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, Data breach, 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., Document, paperwork), or intangible (e.g., knowledge). Information security's primary focus is the balanced protection of data confidentiality, data integrity, integrity, and data availability, availability (also known as the 'CIA' triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process. To stand ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Exploit (computer Security)
An exploit is a method or piece of code that takes advantage of Vulnerability (computer security), vulnerabilities in software, Application software, applications, Computer network, networks, operating systems, or Computer hardware, hardware, typically for malicious purposes. The term "exploit" derives from the English verb "to exploit," meaning "to use something to one’s own advantage." Exploits are designed to identify flaws, bypass security measures, gain unauthorized access to systems, take control of systems, install malware, or data breach, steal sensitive data. While an exploit by itself may not be a malware, it serves as a vehicle for delivering malicious software by breaching security controls. Researchers estimate that malicious exploits cost the global economy over US$450 billion annually. In response to this threat, organizations are increasingly utilizing cyber threat intelligence to identify vulnerabilities and prevent hacks before they occur. Description Expl ...

Threat (computer Security)
In computer security, a threat is a potential negative action or event enabled by a vulnerability that results in an unwanted impact to a computer system or application. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility of a natural disaster event such as an earthquake, a fire, or a tornado) or otherwise a circumstance, capability, action, or event ( incident is often used as a blanket term). A ''threat actor'' who is an individual or group that can perform the threat action, such as exploiting a vulnerability to actualise a negative impact. An '' exploit'' is a vulnerability that a threat actor used to cause an incident. Standard definitions A more comprehensive definition, tied to an Information assurance point of view, can be found in "''Federal Information Processing Standards (FIPS) 200, Minimum ...

Lock And Key
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the '' bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to ...
