Advanced Security: APIs, Hunting, and Automation
Learn advanced DevSecOps: test web and API attacks, hunt threats in your logs, automate security response, and secure AI-powered applications.
What You'll Learn
Understanding What Basic Pipelines Still Miss
A green pipeline tells you the code matches no known bad pattern. It does not tell you the code is safe to expose. It is a Monday morning in Pune.
Testing Web and API Attacks
APIs carry your business logic, so they are where attackers spend their time, and where a simple test with two accounts finds the worst bugs.
Fuzzing APIs and Parsers
Fuzzing finds the inputs nobody thought to test, which is where crashes and denial-of-service bugs hide.
Hunting Threats in Your Logs
Alerts catch what you already know is bad. Hunting finds what you have not thought of yet, before the attacker finishes.
Automating Security Response
Automation turns a ten-minute manual step into a ten-second one, and a wrong automated action into an outage at the same speed.
Securing AI-Powered Applications
An application that sends text to a language model has a new kind of input: text that can change what the program does.

Threat Modeling Many Services as Code
One threat model in a slide deck goes stale in a month; one in the repository gets reviewed with every change.

Practice on the Coding Sheet
Not a software engineer sheet. Every problem comes from real DevOps, SRE, Platform and Cloud interviews, from your first script to a system you build yourself.

BOLA happens when an API returns an object just because the caller knows its ID, without checking that the object belongs to the caller. It is the number one risk in the OWASP API Security Top 10. The fix is an ownership check on every request, in the data query itself.
Scanners look for code patterns and known vulnerable libraries. An authorization bug is valid code that simply does not ask who is calling. Only a test that uses two different accounts, or a person who understands the business rules, can notice the missing check.
No. A fuzzer sends thousands of malformed and unusual requests, including attempts to create, change, and delete data. Run it against a staging copy with test data, and tell the on-call team before you start.
An alert fires on something you already know is bad. A hunt starts from a question, such as whether one account is reading unusually many orders, and searches your logs for evidence. Good hunts often become new alerts.
