Three Secure Development Habits That Prevent Most Web Vulnerabilities

Prevention beats remediation. In our experience these three habits eliminate most findings that routinely show up in web application assessments.

1. Parameterized queries everywhere

SQL injection disappears when every query is prepared and no user input is concatenated into SQL. Same principle applies to command injection, LDAP injection and every other interpreter boundary.

2. Server-side authorization on every request

Never rely on hiding buttons to secure an action. Every endpoint must independently verify that the caller is authenticated and authorized for that specific object and function.

3. Context-aware output encoding

Encode based on where data is emitted: HTML body, attribute, JavaScript, URL, CSS. A single global escape function is not enough — the context decides the encoding.

The habit layer

Habits work when they are enforced in code review, automated tests and shared libraries — not left to each developer to remember.
