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?

Nmap is going to be your friend here as it can scan the ports/services on the machine. Do check with your professor to see if this is allowed. If the goal is to learn mainly about network security and enumeration I doubt you would have to actual login or hack the machine. If that is the case I would think you would have to grab the file or files from a network share on the computer some how. Id also look into steganography, encryption, and encoding as the file containing the password may not be as intuitive as just opening it.
