Asset (computing)
In information security, computer security and network security, an asset is any data, device, or other component of the environment that supports information-related activities. Assets generally include hardware (e.g. servers and switches), software (e.g. mission critical applications and support systems) and confidential information. Assets should be protected from illicit access, use, disclosure, alteration, destruction, and/or theft, resulting in loss to the organization."An Introduction to Factor Analysis of Information Risk (FAIR)", Risk Management Insight LLC, November 2006 ; The CIA triad The goal of |
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] |
Firewall (computing)
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on configurable security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet or between several VLANs. Firewalls can be categorized as network-based or host-based. History The term '' firewall'' originally referred to a wall to confine a fire within a line of adjacent buildings. Later uses refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment. The term was applied in the 1980s to network technology that emerged when the Internet was fairly new in terms of its global use and connectivity. The predecessors to firewalls for network security were routers used in the 1980s. Because they already segregated networks, routers could filter packets crossing them. Before it was used in real-life comput ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Security
Data security or data protection means protecting digital data, such as those in a database, from destructive forces and from the unwanted actions of unauthorized users, such as a cyberattack or a data breach. Technologies Disk encryption Disk encryption refers to encryption technology that encrypts data on a hard disk drive. Disk encryption typically takes form in either software (see disk encryption software) or hardware (see disk encryption hardware). Disk encryption is often referred to as on-the-fly encryption (OTFE) or transparent encryption. Software versus hardware-based mechanisms for protecting data Software-based security solutions encrypt the data to protect it from theft. However, a malicious program or a hacker could corrupt the data to make it unrecoverable, making the system unusable. Hardware-based security solutions prevent read and write access to data, which provides very strong protection against tampering and unauthorized access. Hardware- ...

Risk Management
Risk management is the identification, evaluation, and prioritization of risks, followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. Risks can come from various sources (i.e, Threat (security), threats) including uncertainty in Market environment, international markets, political instability, dangers of project failures (at any phase in design, development, production, or sustaining of life-cycles), legal liabilities, credit risk, accidents, Natural disaster, natural causes and disasters, deliberate attack from an adversary, or events of uncertain or unpredictable root cause analysis, root-cause. Retail traders also apply risk management by using fixed percentage position sizing and risk-to-reward frameworks to avoid large drawdowns and support consistent decision-making under pressure. There are two types of events viz. Risks and Opportunities. Negative events can be classified as risks while positive events are classifi ...

Risk Factor (computing)
In 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, the threat agent capability compared to the vulnerability (computing) and the security control (also called 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: * Environmental, further subdivided in: ** Internal environmental factors are, to a large exten ...

Information Security Management
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factor Analysis Of Information Risk
Factor analysis of information risk (FAIR) is a taxonomy of the factors that contribute to risk and how they affect each other. It is primarily concerned with establishing accurate probabilities for the frequency and magnitude of data loss events. It is not a methodology for performing an enterprise (or individual) risk assessment.Technical Standard Risk Taxonomy Document Number: C081 Published by The Open Group, January 2009. FAIR is also a risk management framework developed by Jack A. Jones, and it can help organizations understand, analyze, and measure information risk according to . A number of methodologies deal with risk management in an IT environment or IT risk, related to information security management systems and standards like ISO/IEC 27000-series. FAIR complements the other methodologies by providing a way to produce consistent, defensible belief statements about risk.

Countermeasure (computer)
In computer security a countermeasure is an action, device, procedure, or technique that reduces a threat, vulnerability, or attack, eliminating or preventing it by minimizing the harm it can cause. It can also include discovering and reporting vunerabilities so that corrective action can be taken. The definition is given in IETF RFC 2828RFC 2828 Internet Security Glossary and CNSS Instruction No. 4009 dated 26 April 2010 by the Committee on National Security Systems.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.

IT Risk Management
IT risk management is the application of risk management methods to information technology in order to manage IT risk. Various methodologies exist to manage IT risks, each involving specific processes and steps. An IT risk management system (ITRMS) is a component of a broader enterprise risk management (ERM) system. ITRMS are also integrated into broader information security management systems (ISMS). The continuous update and maintenance of an ISMS is in turn part of an organisation's systematic approach for identifying, assessing, and managing information security risks. Definitions The Certified Information Systems Auditor Review Manual 2006 by ISACA provides this definition of risk management: "''Risk management is the process of identifying vulnerabilities and threats to the information resources used by an organization in achieving business objectives, and deciding what countermeasures, if any, to take in reducing risk to an acceptable level, based on the value of ...

Encrypt
In cryptography, encryption (more specifically, 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 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 techniques were often used in military m ...
