M15 · SQL Injection

Separate commands and data with parameterized queries.

Concept map

  1. Parameterized queries: keep data as data

    SQL injection crosses the boundary where untrusted input changes query syntax. A fixed query structure with bound values keeps user text in the data position.

  2. Q&A · Decisions & explanations

    Explain the correct choice and why the alternatives fail.

  3. Safe practice & evidence check

    Record your own decision or output, then compare it with the expected result.

Follow the concept map, or go directly to practice if you know the prerequisites. Choose your own pace; there is no daily article quota.
