What is the default Nmap scan type?

The default Nmap scan type is the TCP Connect Scan (-sT). This scan attempts to establish a full TCP connection with the target ports by completing the TCP handshake (SYN, SYN-ACK, ACK).

Key Features of TCP Connect Scan:

• Full Connection: It establishes a complete connection, which means it is easily detectable by the target system.
• Permission Required: Since it completes the handshake, it typically requires permission to connect to the target.
• Simplicity: It is straightforward and works on any system without needing special privileges.

Example Command

To perform a default TCP Connect scan, you can simply run:

nmap target-ip-address

This command will scan the most common 1,000 TCP ports on the specified target using the TCP Connect scan method.
