Blake is in charge of securing all 20 of his company’s servers. He has enabled hardware and
software firewalls, hardened the operating systems, and disabled all unnecessary services on all
the servers. Unfortunately, there is proprietary AS400 emulation software that must run on one of
the servers that requires the telnet service to function properly. Blake is especially concerned
about this since telnet can be a very large security risk in an organization. Blake is concerned
about how this particular server might look to an outside attacker so he decides to perform some
footprinting, scanning, and penetration tests on the server. Blake telnets into the server using Port
80 and types in the following command:
HEAD / HTTP/1.0
