Scan a single IP

This command scans a single IP on the network. If a threat hunter notices strange activity coming from an unfamiliar host, a single IP scan may be useful. Being able to quickly distinguish false positives from false negatives is critical for efficient network security. For example, a network attack might go unnoticed because too many false positives are triggering alerts, creating alert noise.

The alert noise can potentially hide an attack from detection by creating a false negative. The noise also creates confusion and misdirection for the security analyst trying to determine if the attack is real or not. Using an intrusion detection system with an updated attack signature database will help distinguish false positives from false negatives more efficiently. Also, it is important to remember that having too many false negatives can also cause problems. If the intrusion detection system misses an attack, no alerts are activated. This gives the security analyst the illusion that the network is safe and secure, which may not be the case. This is a major issue because an attack could be going on and nobody would be aware of it until it was too late:
