High integrity software

From HandWiki

High-integrity software is software whose failure may cause serious damage with possible "life-threatening consequences."[citation needed] "Integrity is important as it demonstrates the safety, security, and maintainability of... code."[1] Examples of high-integrity software are nuclear reactor control, avionics software, and process control software.[2]

[H]igh integrity means that the code:
  • Does what it should.
  • Can be tested.
  • Has security features.
  • Lacks security vulnerabilities.
  • Is easy to understand and follow logically.
  • Is easy to edit and upgrade without introducing new errors.[1]

A number of standards are applicable to high-integrity software, including:

  • DO-178C, Software Considerations in Airborne Systems and Equipment Certification[3]
  • CENELEC EN 50128, Railway applications - Communication, signalling and processing systems - Software for railway control and protection systems[4]
  • IEC 61508, Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems (E/E/PE, or E/E/PES)
