Official ISTQB Definition
Testing to determine the security of a software product.
In simple words
Trying to break in, leak data, or escalate privileges — before an attacker does.

Security is a non-functional characteristic in ISO 25010; often paired with static analysis and pen-testing.

- Performance TestingHow fast, how many users, how stable under load — response time, throughput, resource usage.
- Static TestingYou examine the work product — requirements, design, code — without running it, using reviews or tools like linters.
