What you will work on

Three tasks from the kind of work interns do in this track. Yours depend on the team you join.

  1. Check a web app for common weaknesses

    Test the login, forms and file uploads against the OWASP Top 10 list, and write up what you find with steps anyone can repeat.

  2. Review who can access what

    Go through the user accounts and permissions on a company tool, and list the ones that should be removed or tightened.

  3. Write a short security guide for staff

    Turn what you found into a one page guide on phishing and passwords that people will actually read.

What your mentor checks

Your mentor is someone from the team. They review what you submit every week and ask questions like these. [REVIEW: how often]

  • Can someone else repeat your finding from your steps?
  • Did you rate how serious it is, and say why?
  • Did you stay inside the agreed scope?
  • Is your suggested fix practical for the team?

Skills you will use

You do not need all of these on day one. The training for this track covers the basics, free if you are selected, and you learn the rest on the job.

  • OWASP Top 10
  • Burp Suite or OWASP ZAP basics
  • Linux command line
  • Networks: ports, DNS, HTTP

  • What is the difference between authentication and authorisation?
  • How would you explain SQL injection to someone who does not code?

Questions about this track

Do I need to know hacking already?

No. You need the basics of networks and the web, and the patience to test carefully. The training for this track covers the starting points, and it is free if you are selected.

Will I test live systems?

Only systems the company owns and has asked us to test, inside a written scope. You never test anything without permission.

Which degree fits?

B.Tech, B.E., BCA or B.Sc in computer science or IT usually fit best. [REVIEW]

Is there any fee?

Applying is free. If you are selected, the internship fee is ₹2,999, paid in two parts: ₹750 when you join, and the other ₹2,249 at least 30 days before your internship ends. Your acceptance letter shows both before you pay anything. The fee includes one mock interview with a mentor. Fees are not refunded, so read your acceptance letter before you pay. There is no fee for the certificate, and the training for your track is free for interns. If anyone asks you for money before you are selected, or for a certificate, it is not us: do not pay, and tell us.

What if this track has no open seats?

We talk about your second choice. If neither fits, you can take a training and apply again for the next batch.
