+## Port Status Information
+- Open: This indicates that an application is listening for connections on this port.
+- Closed: This indicates that the probes were received but there is no application listening on this port.
+- Filtered: This indicates that the probes were not received and the state could not be established. It also indicates that the probes are being dropped by some kind of filtering.
+- Unfiltered: This indicates that the probes were received but a state could not be established.
+- Open/Filtered: This indicates that the port was filtered or open but Nmap couldn’t establish the state.
+- Closed/Filtered: This indicates that the port was filtered or closed but Nmap couldn’t establish the state.

+### Nmap Scripting Engine Categories
+The most common Nmap scripting engine categories:
+- auth: Utilize credentials or bypass authentication on target hosts.
+- broadcast: Discover hosts not included on command line by broadcasting on local network.
+- brute: Attempt to guess passwords on target systems, for a variety of protocols, including http, SNMP, IAX, MySQL, VNC, etc.
+- default: Scripts run automatically when -sC or -A are used.
+- discovery: Try to learn more information about target hosts through public sources of information, SNMP, directory services, and more.
+- dos: May cause denial of service conditions in target hosts.
+- exploit: Attempt to exploit target systems.
+- external: Interact with third-party systems not included in target list.
+- fuzzer: Send unexpected input in network protocol fields.
+- intrusive: May crash target, consume excessive resources, or otherwise impact target machines in a malicious fashion.
+- malware: Look for signs of malware infection on the target hosts.
+- safe: Designed not to impact target in a negative fashion.
+- version: Measure the version of software or protocols on the target hosts.
+- vul: Measure whether target systems have a known vulnerability.
