Harshita Mittal

Cloud security engineer

I lock down cloud infrastructure, then attack the apps running on it. A hardened cloud with a trusting API is still a breach waiting to happen.

Most breaches don't start with a genius exploit. They start with an open port, an over-trusted role, or a server that believes whatever the browser says. I find those first.

Blue team by default. Red team on purpose.

Defense is where I spend most of my time. Offense is how I prove the defense holds.

Primary focus

Defend the cloud

The platform decides how bad any bug can get. I keep AWS small, private and watched.

  • Cloud postureMulti-account AWS audits with Prowler and Wiz, ranked by real risk.
  • Private networkingVPC and Transit Gateway designs with nothing public by accident.
  • Identity and accessIAM and SSO reviews that remove standing admin access.
  • Containers and EKSTrivy image scans and kube-bench CIS checks before release.
  • Detection engineeringWazuh SIEM, file integrity monitoring and Tines automation.
  • Policy as codeCloud and host compliance rules in Rego and OVAL.

Break the app

Manual testing aimed at the bugs scanners walk past.

  • Web and API testingREST and GraphQL, tested by hand, role by role.
  • Authorization flawsIDOR, broken function-level access, UI-only guards.
  • Tokens and sessionsJWT tampering, session handling, SSO flows.
  • Code and dependenciesBranch protection and dependency triage developers can act on.

What I hunt for

Scanners find the obvious. These are the questions I ask by hand, on every app I test.

Can a basic user do an admin's job just by calling the API directly?
Broken function-level accessOWASP API5
What happens if I swap this ID for someone else's?
Object-level access (IDOR)OWASP API1
Is the UI hiding a button, or is the server actually saying no?
Client-side trustCWE-602
Is the API sending data the screen quietly masks?
Excessive data exposureOWASP API3
When something fails at 2 a.m., what gets written down?
Secrets in logsCWE-532
Which doors in this account are open to the whole internet, and why?
