During our first session, we were introduced about hackers, ethical hackers, and crackers. We were told about the differences between hackers and ethical hackers. We were told about the differences of white-box, black-box, and gray-box penetration testing. We were also told about what are the steps to perform a penetration testing (e.g. signing NDA before performing penetration testing). We were also told about our upcoming sessions’ activity and we were also asked to install Kali Linux for our penetration testing. We were also explained about the red and blue team that works on a company and what their roles are. Also, we were explained about script kiddies definition and why being script kiddie is dangerous.
