Question

A penetration tester is tasked with gaining information on one of your internal servers and he enters the following command: telnet server1 80. What is the purpose of this command?

Answer 1

As a penetration tester, the purpose of using this command could be to check whether the web server is accessible and whether it is responding to requests on port 80. By establishing a connection to port 80 using telnet, the tester can send HTTP requests and see if the server responds with the expected HTTP headers or content.

Step-by-step explanation:

This command can be used to gather information about the server, such as the web server software being used, the version of the software, and other configuration details. This information can be useful in identifying vulnerabilities and weaknesses that could be exploited to gain unauthorized access to the server.
