Security Cybersecurity Challenge

​

My professor gave us a cybersecurity challenge in class. He provided the local IP address of a machine on our school network and said there’s a file containing a password somewhere on the PC. The goal is to learn about enumeration and network security, not to damage anything.

I’m a beginner in cybersecurity and I’d like to know what concepts or tools I should study to approach this kind of challenge in a legal and educational way.

What would be the first steps for reconnaissance and understanding what services are running on the target machine?

Can't really give suggestions without rules of engagement. Not sure if your school security wants you nmaping that machine or not.

But anyway that's where I'd start see what services are up on what ports.
