What is a DMZ?

What is an IDS?
IDS stand for intrusion detection system
It is a type of network security system that receives copies of all incoming traffic and then analyzes the traffic for patterns that indicate a threat.
It is important to note that an IDS does not stop an attack from happening or continuing.
What is an IPS?

It is a type of network security system
What is an HIDS / HIPS and how does it differ from an IDS / IPS?
HIDS / HIPS stands for host-based instruction detection/prevention system
The distinction is that rather than the security system being a separate piece of hardware, and thus creating an additional network segment, the system is instead software which resides and operates on the destination host or resource.
