Secure Software Implementation

Secure Software Implementation covers writing code that resists injection, XSS, CSRF, and weak crypto. CSSLP questions here are scenario-based: pick the correct CSP directive, choose three SQLi defenses, select database encryption practice, and configure Spring Security to stop CSRF on state-changing requests.

What this domain covers

What to know about Secure Software Implementation

Be able to choose the right control for each flaw: CSP script-src, parameterized queries plus validation and least privilege, AES with proper key management for data at rest, and Spring Security CSRF tokens on state-changing requests. The key is matching the control to the exact attack.

Selecting CSP directives such as script-src to restrict script loading sources

Applying parameterized queries, input validation, and least-privilege database accounts against SQL Injection

Using AES encryption, key management, and column-level encryption for data at rest

Configuring Spring Security CSRF protection for state-changing HTTP methods

Watch out for

Common Secure Software Implementation exam traps

  • ▸Confusing CSP default-src with script-src; default-src is a fallback, not the script-specific restriction
  • ▸Believing input escaping alone stops SQL Injection while missing parameterized queries and least privilege
  • ▸Disabling CSRF globally in Spring Security instead of scoping protection to state-changing requests
