A threat actor or malicious actor is a person or entity responsible for an event or incident that impacts, or has the potential to impact, the safety or security of another entity. Most often, the term is used to describe individuals and groups that perform malicious acts against organizations of various types and sizes. From a threat intelligence perspective, threat actors are often categorized as either unintentional or intentional and either external or internal.
Risk management is the identification, evaluation, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities.
An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms.
Internet security is a branch of computer security specifically related to not only Internet, often involving browser security and the World Wide Web, but also network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information, which leads to a high risk of intrusion or fraud, such as phishing, online viruses, trojans, worms and more.
In computer security, a vulnerability is a weakness which can be exploited by a threat actor, such as an attacker, to perform unauthorized actions within a computer system. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerabilities are also known as the attack surface.
Mainstream media is a place where anyone can contribute to important issues and topics of discussion. Media Democracy encompasses this idea by advocating for ideas such as free and independent press. The overarching goal is to achieve a free, open, and accessible internet for everyone. Thus creating a diverse space for media ownership from all walks of life to contribute into a larger collective without suppression. Such campaigns include “Freedom of The Press”, “BroadBand Access”, “Net Neutrality”, and “Media Consolidation”.
Secure by design, in software engineering, means that the software has been designed from the foundation to be secure. In such approach, the alternate security tactics and patterns are first thought; among them, the best are selected and enforced by the architecture design, and then used as guiding principles for developers. Secure by Design is more increasingly becoming the mainstream development approach to ensure security and privacy of software systems. In this approach, security is built in the system from the ground up and starts with a robust architecture design. Security architectural design decisions are often based on well-known security tactics, and patterns defined as reusable techniques for achieving specific quality concerns. Security tactics/patterns provide solutions for enforcing the necessary authentication, authorization, confidentiality, data integrity, privacy, accountability, availability, safety and non-repudiation requirements, even when the system is under attack. In order to ensure the security of a software system, not only it is important to design a robust security architecture (intended) but also it is necessary to preserve the (implemented) architecture during software evolution. Malicious practices are taken for granted and care is taken to minimize impact in anticipation of security vulnerabilities, when a security vulnerability is discovered or on invalid user input. Closely related is the practice of using "good" software design, such as domain-driven design or cloud native, as a way to increase security by reducing risk of vulnerability-opening mistakes—even though the design principles used were not originally conceived for security purposes.
Crimeware is a class of malware designed specifically to automate cybercrime.
Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information or data and the systems and processes used for those purposes. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data. It uses physical, technical, and administrative controls to accomplish these tasks. While focused predominantly on information in digital form, the full range of IA encompasses not only digital, but also analog or physical form. These protections apply to data in transit, both physical and electronic forms, as well as data at rest in various types of physical and electronic storage facilities. IA is best thought of as a superset of information security, and as the business outcome of information risk management.
Physical information security is the intersection, the common ground between physical security and information security. It primarily concerns the protection of tangible information-related assets such as computer systems and storage media against physical, real-world threats such as unauthorized physical access, theft, fire and flood. It typically involves physical controls such as protective barriers and locks, uninterruptible power supplies, and shredders. Information security controls in the physical domain complement those in the logical domain, and procedural or administrative controls.
Internet safety or online safety or cyber safety or E-Safety is trying to be safe on the internet and is the act of maximizing a user's awareness of personal safety and security risks to private information and property associated with using the internet, and the self-protection from computer crime.
Indignation is a complex and discrete emotion that is triggered by social emotions and social environments. Feelings of anger and disgust are some emotions that make up indignation.
Information technology risk, IT risk, IT-related risk, or cyber risk is any risk related to information technology. While information has long been appreciated as a valuable and important asset, the rise of the knowledge economy and the Digital Revolution has led to organizations becoming increasingly dependent on information, information processing and especially IT. Various events or incidents that compromise IT in some way can therefore cause adverse impacts on the organization's business processes or mission, ranging from inconsequential to catastrophic in scale.
Misuse case is a business process modeling tool used in the software development industry. The term Misuse Case or mis-use case is derived from and is the inverse of use case. The term was first used in the 1990s by Guttorm Sindre of the Norwegian University of Science and Technology, and Andreas L. Opdahl of the University of Bergen, Norway. It describes the process of executing a malicious act against a system, while use case can be used to describe any action taken by the system.
A web threat is any threat that uses the World Wide Web to facilitate cybercrime. Web threats use multiple types of malware and fraud, all of which utilize HTTP or HTTPS protocols, but may also employ other protocols and components, such as links in email or IM, or malware attachments or on servers that access the Web. They benefit cybercriminals by stealing information for subsequent sale and help absorb infected PCs into botnets.
An advanced persistent threat (APT) is a stealthy computer network threat actor, typically a nation state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period. In recent times, the term may also refer to non-state sponsored groups conducting large-scale targeted intrusions for specific goals.
In computer security, a threat is a possible danger that might exploit a vulnerability to breach security and therefore cause possible harm.
In Information security, Risk factor is a collective name for circumstances affecting the likelihood or impact of a security risk.
An enemy or a foe is an individual or a group that is considered as forcefully adverse or threatening. The concept of an enemy has been observed to be "basic for both individuals and communities". The term "enemy" serves the social function of designating a particular entity as a threat, thereby invoking an intense emotional response to that entity. The state of being or having an enemy is enmity, foehood or foeship.
An insider threat is a malicious threat to an organization that comes from people within the organization, such as employees, former employees, contractors or business associates, who have inside information concerning the organization's security practices, data and computer systems. The threat may involve fraud, the theft of confidential or commercially valuable information, the theft of intellectual property, or the sabotage of computer systems. The insider threat comes in three categories:
In computers and computer networks an attack is any attempt to expose, alter, disable, destroy, steal or gain unauthorized access to or make unauthorized use of an asset. A cyberattack is any type of offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices. An attacker is a person or process that attempts to access data, functions or other restricted areas of the system without authorization, potentially with malicious intent. Depending on context, cyberattacks can be part of cyberwarfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, society or organizations, and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyberweapon.
