STRIDE is a threat modelling methodology developed within Microsoft, and is a mnemonic for six security threat categories. In plain language, STRIDE can thought to stand for:

  • Spoofing - pretending to be someone else
  • Tampering - messing with stuff you’re not supposed to
  • Repudiation - denying you did something, even if you did
  • Information Disclosure - exposing private information
  • Denial of Service - crashing a system so nobody can use it
  • Elevation of Privilege - gaining access you shouldn’t have
