Practices

Shift Left

Shift-left security means moving testing and security feedback earlier in the software lifecycle - into design, coding, and CI - so issues are caught when they are cheapest to fix. Shifting left is most effective when paired with continuous testing of running applications, so runtime and logic flaws are not missed.

Key points

  • Catches issues early, when remediation is cheapest.
  • Complements, not replaces, runtime and continuous testing.
  • A core principle of DevSecOps.
