What (who) is reliability threat - definition

A SUB-DISCIPLINE OF SYSTEMS ENGINEERING THAT EMPHASIZES DEPENDABILITY IN THE LIFECYCLE MANAGEMENT OF A PRODUCT OR A SYSTEM

Reliable system design; Reliability theory; Reliability testing; Reliability theory (engineering); Reliability modelling; Reliability (engineering); Experimental reliability; Software reliability; Critical failure; Reliability Engineering; Point of failure; Points of failure; Single point of contention; Reliability modeling; Systems reliability; Inter-method reliability; Parallel-forms Reliability; Inter-method variation; Reliability level; User:Stochastikon-bernoulli/Reliability Level; Reliability Level; Reliability engineer; Reliability Engineer; History of reliability engineering; RDF2000; Reliability test

Threat model

PROCESS BY WHICH POTENTIAL THREATS, SUCH AS STRUCTURAL VULNERABILITIES CAN BE IDENTIFIED, ENUMERATED, AND PRIORITIZED – ALL FROM A HYPOTHETICAL ATTACKER’S POINT OF VIEW

Threat modeling; Threat Modeling; Threat modelling

Threat modeling is a process by which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified and enumerated, and countermeasures prioritized. The purpose of threat modeling is to provide defenders with a systematic analysis of what controls or defenses need to be included, given the nature of the system, the probable attacker's profile, the most likely attack vectors, and the assets most desired by an attacker.

Reliability (computer networking)

ABILITY OF A COMPUTER NETWORK PROTOCOL TO NOTIFY THE SENDER OF WHETHER DELIVERY OF DATA WAS SUCCESSFUL

Reliability properties; Strong reliability properties; Reliable messaging; Reliable messaging service; Reliable messaging system; Reliable communications; Assurance (computer networking); Reliable delivery

In computer networking, a reliable protocol is a communication protocol that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for assurance, which is the term used by the ITU and ATM Forum.

High reliability organization

ORGANIZATIONS OPERATING COMPLEX, HIGH-HAZARD DOMAINS FOR EXTENDED PERIODS WITHOUT SERIOUS ACCIDENTS OR CATASTROPHIC FAILURES

High reliability organisation; High reliability organisations; High Reliability Organisation; High Reliability Organisations; High Reliability Organizations; High Reliability Organization; HROs

A high reliability organization (HRO) is an organization that has succeeded in avoiding catastrophes in an environment where normal accidents can be expected due to risk factors and complexity.

Wikipedia

Reliability engineering

Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time.

The reliability function is theoretically defined as the probability of success at time t, which is denoted R(t). This probability is estimated from detailed (physics of failure) analysis, previous data sets or through reliability testing and reliability modelling. Availability, testability, maintainability and maintenance are often defined as a part of "reliability engineering" in reliability programs. Reliability often plays the key role in the cost-effectiveness of systems.

Reliability engineering deals with the prediction, prevention and management of high levels of "lifetime" engineering uncertainty and risks of failure. Although stochastic parameters define and affect reliability, reliability is not only achieved by mathematics and statistics. "Nearly all teaching and literature on the subject emphasize these aspects, and ignore the reality that the ranges of uncertainty involved largely invalidate quantitative methods for prediction and measurement." For example, it is easy to represent "probability of failure" as a symbol or value in an equation, but it is almost impossible to predict its true magnitude in practice, which is massively multivariate, so having the equation for reliability does not begin to equal having an accurate predictive measurement of reliability.

Reliability engineering relates closely to Quality Engineering, safety engineering and system safety, in that they use common methods for their analysis and may require input from each other. It can be said that a system must be reliably safe.

Reliability engineering focuses on costs of failure caused by system downtime, cost of spares, repair equipment, personnel, and cost of warranty claims.
