Learn Basic Network and Web Application scanning with Nessus Essentials - free version of the vulnerability scanner.
DESCRIPTION:
TRYHACKME made familiarizing with NESSUS nice and easy with THIS free room with 5 tasks.
My impression is that the room authors' sentences are clear and explanations are easy to follow, you won't get much trouble with this room unless you don't allocate enough of SYSTEM RESOURCES to install Nessus. Yes, you have to install Nessus on your own machine and use OpenVPN configuration file provided with your THM account, not AttackBox nor subcription will help you with that.
So, the installation will take some time... You will probably want to move on something else in the meantime or sleep on it.
Read the instructions provided in the room, i will post here only tasks that need answers, screenshots that lead to answers and spoilers. These are tasks 3-5.
Not to ruin the party for interested, answers are hidden, so if interested, click on the question below and the answer will reveal itself. Let's go!
