How do you write a complete Misuse Case description for a SQL Injection attack?
Fill every template field with specific, testable detail — name, mis-actor, entry point, attributes hit, basic path, mitigation — because a vague threat ("login could be attacked") only ever produces a vague, unverifiable fix.
The discipline is what makes a misuse case actionable: a concrete basic path becomes a penetration-test case, the named mitigation becomes a written security requirement, and the sophistication/access fields feed risk-scoring so you know what to fix first.
Worked example:
| Field | Value |
|---|---|
| Name | SQL Injection via Login Form |
| Priority | High |
| Scope | Authentication module |
| Mis-actor | External attacker (unauthenticated) |
| Access Right Level | None required (public-facing form) |
| Point of Entry | Username and password fields on /login |
| Security Attributes | Confidentiality (data leak), Integrity (data modification), Authorization (bypass login) |
| Sophistication | Low (automated tools like sqlmap exist) |
| Pre-conditions | Login page is accessible; application uses SQL database |
| Basic Path | 1. Attacker enters ' OR 1=1 -- in username field → 2. Application concatenates input into SQL query → 3. Database executes modified query → 4. Attacker bypasses authentication |
| Alternative Paths | UNION-based extraction of database contents; blind SQL injection via timing |
| Triggers | Attacker submits login form with crafted input |
| Assumptions | Application uses string concatenation for SQL queries (no parameterized queries) |
| Mitigation | Parameterized queries/prepared statements; input validation; WAF rules |
Why each field matters:
- Sophistication + Access Level → determines DREAD Exploitability score
- Security Attributes → maps directly to STRIDE categories
- Basic Path → becomes the test case for penetration testing
- Mitigation → becomes a security requirement: "The system SHALL use parameterized queries for all database operations"
