10 Top OS for Ethical Hacking and Penetration Testing by Sourodip Biswas

In today’s digital world, a lot of cyber-attacks happen every day that could have been avoided if the back doors and weaknesses in the system were patched up. In order to discover such back doors, ethical hackers and pentesters use various operating systems. Here, we have a list of the 10 top OS’s that are used by professionals. 

Top 10 Operating Systems for Ethical Hacking and Penetration Testing

1. Kali Linux
