Threat Agent
In computer security, a threat is a potential negative action or event facilitated 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.Internet Engineering Task Force RFC 2828 Internet Security Glossary This is differentiated from 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. A more comprehensive definition, tied to an Information assurance point of view, can be found in "''Federal Information Processing Standards (FIPS) 200, Minimum Security Requirements for Federal Information and Informat ...

Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Integrity
Integrity is the practice of being honest and showing a consistent and uncompromising adherence to strong moral and ethical principles and values. In ethics, integrity is regarded as the honesty and truthfulness or accuracy of one's actions. Integrity can stand in opposition to hypocrisy, in that judging with the standards of integrity involves regarding internal consistency as a virtue, and suggests that parties holding within themselves apparently conflicting values should account for the discrepancy or alter their beliefs. The word ''integrity'' evolved from the Latin adjective ''integer'', meaning ''whole'' or ''complete''. In this context, integrity is the inner sense of "wholeness" deriving from qualities such as honesty and consistency of character. In ethics In ethics, an individual is said to possess the virtue of integrity if the individual's actions are based upon an internally consistent framework of principles. These principles should uniformly adhere to sound logi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk Factor (computing)
In Information security, information security, risk factor is a collective name for circumstances affecting the likelihood or impact of a security risk. Definitions FAIR Factor Analysis of Information Risk (FAIR) is devoted to the analysis of different factors influencing IT risk. It decompose at various levels, starting from the first level Loss Event Frequency and Probable Loss Magnitude, going on examining the asset (computing), asset, the threat (computer), threat agent capability compared to the vulnerability (computing) and the security control (also called countermeasure (computer), countermeasure) strength, the probability that the agent get in contact and actually act against the asset, the organization capability to react to the event and the impact on stakeholders. ISACA Risk factors are those factors that influence the frequency and/or business impact of risk scenarios; they can be of different natures, and can be classified in two major categories: * Environm ...

Security Service (telecommunication)
Security service is a service, provided by a layer of communicating open systems, which ensures adequate security of the systems or of data transfers as defined by ITU-T X.800 Recommendation. X.800 and ISO 7498-2 (Information processing systems – Open systems interconnection – Basic Reference Model – Part 2: Security architecture) are technically aligned. This model is widely recognized William Stallings Crittografia e sicurezza delle reti Seconda edizione Traduzione Italiana a cura di Luca Salgarelli di Cryptography and Network security 4 edition Pearson 2006 Securing information and communications systems: principles, technologies, and applications Steven Furnell, Sokratis Katsikas, Javier Lopez, Artech House, 2008 - 362 pages A more general definition is in CNSS Instruction No. 4009 dated 26 April 2010 by Committee on National Security Systems of United States of America: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countermeasure (computer)
In computer security a countermeasure is an action, device, procedure, or technique that reduces a threat, a vulnerability, or an attack by eliminating or preventing it, by minimizing the harm it can cause, or by discovering and reporting it so that corrective action can be taken. The definition is as IETF RFC 2828RFC 2828 Internet Security Glossary that is the same as CNSS Instruction No. 4009 dated 26 April 2010 by Committee on National Security Systems of United States of America.CNSS Instruction No. 4009 dated 26 April 2010 According to the Glossary b InfosecToday the meaning of countermeasure is: :The deployment of a set of security services to protect against a security threat.

Information Security Management System
Information security management (ISM) defines and manages controls that an organization needs to implement to ensure that it is sensibly protecting the confidentiality, availability, and integrity of assets from threats and vulnerabilities. The core of ISM includes information risk management, a process that involves the assessment of the risks an organization must deal with in the management and protection of assets, as well as the dissemination of the risks to all appropriate stakeholders. This requires proper asset identification and valuation steps, including evaluating the value of confidentiality, integrity, availability, and replacement of assets. As part of information security management, an organization may implement an information security management system and other best practices found in the ISO/IEC 27001, ISO/IEC 27002, and ISO/IEC 27035 standards on information security. Risk management and mitigation Managing information security in essence means managing and mitiga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Controls
Security controls are safeguards or countermeasures to avoid, detect, counteract, or minimize security risks to physical property, information, computer systems, or other assets. In the field of information security, such controls protect the confidentiality, integrity and availability of information. Systems of controls can be referred to as frameworks or standards. Frameworks can enable an organization to manage security controls across different types of assets with consistency. Types of security controls Security controls can be classified by various criteria. For example, controls are occasionally classified by when they act relative to a security breach: *Before the event, preventive controls are intended to prevent an incident from occurring e.g. by locking out unauthorized intruders; *During the event, detective controls are intended to identify and characterize an incident in progress e.g. by sounding the intruder alarm and alerting the security guards or police; *Afte ...

2010-T10-ArchitectureDiagram
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Attack
A passive attack on a cryptosystem is one in which the cryptanalyst cannot interact with any of the parties involved, attempting to break the system solely based upon observed data (i.e. the ciphertext). This can also include known plaintext attacks where both the plaintext and its corresponding ciphertext are known. While active attackers can interact with the parties by sending data, a passive attacker is limited to intercepting communications (eavesdropping), and seeks to decrypt data by interpreting the transcripts of authentication sessions. Since passive attackers do not introduce data of their own, they can be difficult to detect. While most classical ciphers are vulnerable to this form of attack, most modern ciphers are designed to prevent this type of attack above all others. Attributes *Traffic analysis *Non-evasive eavesdropping and monitoring of transmissions *Because data unaffected, tricky to detect *Emphasis on prevention (encryption) not detection *Sometimes ref ...

Attack (computing)
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, 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 the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organisations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyber attacks have increased with an alarming rate for the last few years A cyberattack may steal, alter, or destroy a specified target by hacking into a susceptible system. Cyberattacks can range from installing spyware on a personal computer to attempting to destroy the infrastructure of entire nations. Legal experts are seeking to limit the use of the ter ...
