What is a host discovery scan?

Host discovery is usually referred to as ‘Ping’ scanning using a sonar analogy. The goal is to send a packet through to the IP address and solicit a response from the host. As such, a ‘ping’ can be virtually any crafted packet whatsoever, provided the adversary can identify a functional host based on its response.

What is stealth scanning?

Stealth scans Stealth scan types are those where packet flags cause the target system to respond without having a fully established connection. Stealth scanning is used by hackers to circumvent the intrusion detection system (IDS), making it a significant threat.
