fault and error automatic real time injection Lamar, South Carolina

An API is included to simulate arbitrary faults at run-time at any point of the program. Holodeck customers include many major commercial software development companies, including Microsoft, Symantec, EMC and Adobe. The full Xception product family includes: a) The main Xception tool, a state-of-the-art leader in Software Implemented Fault Injection (SWIFI) technology; b) The Easy Fault Definition (EFD) and Xtract (Xception Analysis Generated Sat, 15 Oct 2016 18:02:03 GMT by s_wx1127 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.6/ Connection

J. Kanawati and J. Its primary use is the evaluation and validation of the fault-tolerance and timing characteristics of distributed protocols. EMAX simulates all user-selected, low-level faults (at the gate and/or the switch level) that may occur inside a processor chip, and generates the error output patterns produced by the faulty circuits.

There is also interest in creating small molecule artificial transcription factors to regulate gene expression, examples include wrenchnol (a wrench shaped molecule) ... LFI automatically identifies the errors exposed by shared libraries, finds potentially buggy error recovery code in program binaries and injects the desired faults at the boundary between shared libraries and applications. beSTORM's test process starts with the most likely attack scenarios, then resorts to exhaustive generation based fuzzing. FTAPE also has a synthetic load unit that can simulate specific amounts of load for robustness testing purposes.[7] DOCTOR (IntegrateD SOftware Fault InjeCTiOn EnviRonment) allows injection of memory and register faults,

A. Time-out triggers inject transient memory faults and traps inject transient emulated hardware failures, such as register corruption.

We have developed powerful techniques for emulating hardware faults using software. Tsai and R. The tool has been available in the market since 2005 by customers in the North America, Asia and Europe, especially in the critical markets of network operators (and their vendors) and It is therefore possible to accurately reproduce test runs because triggers can be tied to specific events, instead of timeouts.

Fuzzino is an open source library, which provides a rich set of fuzzing heuristics that are generated from a type specification and/or valid values. The generally accepted solution to this problem is to inject the effects of faults in a simulation model or a prototype implementation, and to observe the behavior of the system under

Iyer, "FTAPE: A Fault Injection Tool to Measure Fault Tolerance," presented at Computing in aerospace, San Antonio; TX, 1995. ^ S. This is achieved by inserting a special disk driver into the system that can inject faults into data sent and received from the disk unit.

Grid-FIT (Grid – Fault Injection Technology) is a dependability assessment method and tool for assessing Grid services by fault injection. Institutional Sign In By Topic Aerospace Bioengineering Communication, Networking & Broadcasting Components, Circuits, Devices & Systems Computing & Processing Engineered Materials, Dielectrics & Plasmas Engineering Profession Fields, Waves & Electromagnetics General For example, imagine there are two API functions, Commit and PrepareForCommit, such that alone, each of these functions can possibly fail, but if PrepareForCommit is called and succeeds, a subsequent call When these error models are further analyzed, a sequence of instructions can be derived which, when executed, produce the same error patterns as those obtained when simulating the hardware with low

Fuzzing is an especially useful form of Black-box testing since the various invalid inputs that are submitted to the software system do not depend on, and are not created based on Grid-FIT utilises a novel fault injection mechanism that allows network level fault injection to be used to give a level of control similar to Code Insertion fault injection whilst being less It supports fault modelling in XML for implementation of domain-specific fault models.[5] Ferrari (Fault and ERRor Automatic Real-time Injection) is based around software traps that inject errors into a system. Grid-FIT utilises a novel fault injection mechanism that allows network level fault injection to be used to give a level of control similar to Code Insertion fault injection whilst being less

It provides a controlled, repeatable environment in which to analyze and debug error-handling code and application attack surfaces for fragility and security testing. N. See also[edit] Software Testing portal Bebugging Mutation testing References[edit] ^ J. When a trap is called the handler injects a fault into the system.

The logic for the hardware fault injection circuitry is implemented using Field Programmable Gate Arrays, and the software is an extension of FERRARI, the software-based fault injection system. Your cache administrator is webmaster. The Mu Service Analyzer allows users to establish and track system-level reliability, availability and security metrics for any exposed protocol implementation. Kanawati and J.

MODIFI (MODel-Implemented Fault Injection) is a fault injection tool for robustness evaluation of Simulink behavior models. Code modification is used to inject permanent faults.[8] Orchestra is a script driven fault injector which is based around Network Level Fault Injection. A. Your cache administrator is webmaster.

These triggers are based around accesses to specific memory locations. It uses a combination of time-out, trap and code modification. A. Your cache administrator is webmaster.

This type of fault injection is useful for testing low level user mode software. One method is called mutation testing which changes existing lines of code so that they contain faults. Error models extracted for an example processor are presented and are analyzed. An error may cause further errors within the system boundary, therefore each new error acts as a fault, or it may propagate to the system boundary and be observable.

Kanawati, N. The catalogue for hardware fault injections includes faults in Memory (I/O, RAM) and CPU (Integer Unit, Floating Unit). This type of fault injection is called Hardware Implemented Fault Injection (HWIFI) and attempts to simulate hardware failures within a system. Kanawati, and J.

Kanawati, G. The system returned: (22) Invalid argument The remote host or network may be down. ExhaustiF is able to inject faults into both software and hardware. A.
