Joe analyzed the following log and determined the security team should implement which of the
following as a mitigation method against further attempts?

Explanation:
We can see a number of unsuccessful login attempts using a Remote Desktop Connection (using
the RDP protocol) from a computer with the IP address 192.168.1.124.
Someone successfully logged in locally. This is probably an authorized login (for example, Joe
logging in).
Hardening is the process of securing a system. We can harden (secure) the system by either
disallowing remote desktop connections altogether or by restricting which IPs are allowed to
initiate remote desktop connections.
