Violation de donnéesUne fuite de données consiste en la copie, la transmission, la visualisation, le vol ou l'utilisation d'informations confidentielles, sensibles ou protégées par une personne non autorisée. Les fuites de données impliquent souvent des informations financières telles que des numéros de carte de crédit ou des informations bancaires, les renseignements médicaux personnels (DMP), les informations personnelles identifiables (PII), les secrets commerciaux de sociétés ou de la propriété intellectuelle.
Proactive cyber defenceProactive cyber defence, means acting in anticipation to oppose an attack through cyber and cognitive domains. Proactive cyber defence can be understood as options between offensive and defensive measures. It includes interdicting, disrupting or deterring an attack or a threat's preparation to attack, either pre-emptively or in self-defence. Proactive cyber defence differs from active defence, in that the former is pre-emptive (does not waiting for an attack to occur).
Information security auditAn information security audit is an audit of the level of information security in an organization. It is an independent review and examination of system records, activities, and related documents. These audits are intended to improve the level of information security, avoid improper information security designs, and optimize the efficiency of the security safeguards and security processes. Within the broad scope of auditing information security there are multiple types of audits, multiple objectives for different audits, etc.
Managed security serviceIn computing, managed security services (MSS) are network security services that have been outsourced to a service provider. A company providing such a service is a managed security service provider (MSSP) The roots of MSSPs are in the Internet Service Providers (ISPs) in the mid to late 1990s. Initially, ISP(s) would sell customers a firewall appliance, as customer premises equipment (CPE), and for an additional fee would manage the customer-owned firewall over a dial-up connection.
Vulnerability managementVulnerability management is the "cyclical practice of identifying, classifying, prioritizing, remediating, and mitigating" software vulnerabilities. Vulnerability management is integral to computer security and network security, and must not be confused with vulnerability assessment. Vulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities, such as open ports, insecure software configurations, and susceptibility to malware infections.
W3afw3af (Web Application Attack and Audit Framework) is an open-source web application security scanner. The project provides a vulnerability scanner and exploitation tool for Web applications. It provides information about security vulnerabilities for use in penetration testing engagements. The scanner offers a graphical user interface and a command-line interface. w3af is divided into two main parts, the core and the plug-ins. The core coordinates the process and provides features that are consumed by the plug-ins, which find the vulnerabilities and exploit them.
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 A more general definition is in CNSS Instruction No.
Threat (computer)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.
Asset (computer security)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.
Risk factor (computing)In information security, risk factor is a collective name for circumstances affecting the likelihood or impact of a security risk. Factor Analysis of Information Risk#Risk 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.
