Hi @hafsa ,
I understand you want to start your cybersecurity studies.
You might want to consider going first for the Certified in Cybersecurity certification.
Since for this certification no working experience is required and you will be building a solid foundation of cybersecurity to then move toward your CISSP.

I wish you all the best in your cybersecurity studies.
