Computers & IT (Non-Engg)

There is no direct entry to become Cyber Crime Officer in India. You can join police services as Sub inspector by appearing for State Service board examination or IPS by clearing Civil Services Examination conducted by UPSC. Once you are in police you can specialize in cyber crime. You are eligible to appear for Civil Services Examination and State Service Selection Board Examination on completion of your graduation degree in Commerce.

If you have math in your graduation degree, you can apply for MCA.
