Fuzzing

As explained in AI for Everyday IT

Fuzz testing is a software-testing technique that supplies automatically generated, malformed, or unexpected inputs to find failures and vulnerabilities.

Fuzz testing supplies software with malformed or unexpected inputs to expose failures and vulnerabilities. It is especially useful as a security check for AI-generated code, alongside careful human review. section 11.9.1

Use fuzz testing when reviewing code that:

  • Handles authentication, data access, or user input, where unexpected inputs can create security problems. section 11.9.1
  • Was generated or modified by an AI assistant and therefore requires the same security standards and review process as human-written code. section 11.9.1

Practical review

After an AI assistant produces code for a login or data-access component, run security scanners and fuzz testing before treating the implementation as ready. Use the results to guide human review rather than assuming generated code is safe. section 11.9.1

How AI for Everyday IT covers it

How deep it goes
Defines the purpose and target areas but stops short of specifying fuzzing tools, input-generation methods, or execution procedures.
Examples
Targets AI-generated components handling authentication, data access, or user input.
What it assumes
Assumes security standards and human review processes, while emphasizing that both AI- and human-written code require them.
What you can do after
Diagnose failures and vulnerabilities in security-sensitive code before accepting it as safe.
How it connects
Connects fuzz testing with security scanners, human code review, authentication, data access, and user input.
