Computer security fault tolerance

  • How is fault tolerance achieved in a network?

    At a hardware level, fault tolerance is achieved by duplexing each hardware component.
    Disks are mirrored.
    Multiple processors are lockstepped together and their outputs are compared for correctness..

  • How is fault tolerance used to measure a computer's performance?

    One possible way of measuring fault-tolerance is by defining the redundancy in a system, perhaps achieved through interchangeable components that can substitute for each other if one (or more) of the components fail..

  • What are the fault-tolerant computer companies?

    Fault-Tolerant Players
    Vendors in this market include Stratus Computer Systems in Maynard, Mass.; Compaq Computer Corp., with its NonStop Himalaya systems; IBM, with its SP systems; and Boxborough, Mass. -based Marathon Technologies Corp., a vendor of fault-tolerant configurations for Windows NT systems..

  • What are the methods of fault-tolerant computing?

    Fault tolerance can be implemented using one of two basic approaches: (1) fault masking, where the system masks the effect of a fault through some form of majority voting; (2) fault detection and recovery, where a system has a method for first detecting the presence of a fault, subsequently locating where the fault has .

  • What is fault-tolerance in cryptography?

    Blockchain technology.
    Byzantine fault tolerance is a measure of the ability of a distributed system to continue operating even if one or more of its components fails..

  • What is fault-tolerant control system?

    Fault-tolerant control is the synonym for a set of recent techniques that were developed to increase plant availability and reduce the risk of safety hazards.
    Its aim is to prevent that simple faults develop into serious failure..

  • What is the purpose of a fault tolerant computer?

    Fault tolerance is a process that enables an operating system to respond to a failure in hardware or software.
    This fault-tolerance definition refers to the system's ability to continue operating despite failures or malfunctions..

  • Why is fault tolerance a desired attribute in a system?

    Fault tolerance is intended to preserve the delivery of correct service in the presence of active faults.
    It is generally implemented by error detection and subsequent system recovery..

  • Why is Internet fault tolerant?

    A big contributor to the fault tolerance of the Internet is the redundancy in network routing paths.
    A map of undersea cables crossing the Atlantic ocean.
    Shows more than 10 cables connecting the East Coast of the United States with various points in Europe..

  • Reliability/Fault-tolerance: In storage systems, fault-tolerance is the ability to consistently access correct data.
    The longer a disk remains operable the more it can be accessed, however it must also provide non-volatile storage – when it is accessed it must supply data that is consistent with past operations.
  • Without fault tolerance, distributed systems are prone to downtime, data loss, and performance degradation, which can lead to financial losses, reputational damage, and loss of customer trust.
Fault Tolerance Defined Fault tolerance is a process that enables an operating system to respond to a failure in hardware or software. This fault-tolerance definition refers to the system's ability to continue operating despite failures or malfunctions.
Fault tolerance is a process that enables an operating system to respond to a failure in hardware or software. This fault-tolerance definition refers to the system's ability to continue operating despite failures or malfunctions.
Fault tolerance is reliant on aspects like load balancing and failover, which remove the risk of a single point of failure. It will typically be part of the operating system's interface, which enables programmers to check the performance of data throughout a transaction.
The goal of fault tolerant computer systems is to ensure business continuity and high availability by preventing disruptions arising from a single point of failure. Fault tolerance solutions therefore tend to focus most on mission-critical applications or systems.
Intrusion tolerance is a fault-tolerant design approach to defending information systems against malicious attacks.
In that sense, it is also a computer security approach.
Abandoning the conventional aim of preventing all intrusions, intrusion tolerance instead calls for triggering mechanisms that prevent intrusions from leading to a system security failure.
