nmap

Nmap Scan Report Summary:

• Host xxx.xx.xx.x: This is the IP address of the target machine that was scanned.

• Host is up (0.0012s latency): The target machine is online, and the round-trip time for a packet to go from the source machine (your computer) to the target and back was approximately 0.0012 seconds.

• Not shown: 970 closed tcp ports (reset): Out of the scanned range, 970 ports responded as closed. They're not displayed to keep the output manageable.

Port and State Information:

The columns explain the status of various ports and the services commonly associated with them.

• PORT: The network port number on the target machine.

• STATE: Status of the port. States include:

  • open: The port is accessible.

  • filtered: Nmap can't determine whether the port is open due to packet filtering (usually by a firewall).

• SERVICE: The common service expected to be running on that port.

Noteworthy Points:

• Ports 135 and 445: These are typical for Windows machines and are associated with MSRPC and SMB/CIFS services, respectively. Be cautious as these services can be prone to vulnerabilities if not properly configured and patched.

• Port 2179 (vmrdp): Virtual Machine Remote Desktop Protocol is running. This could mean that a virtual machine is hosted on this machine and is accepting RDP connections.

• Port 3300 (ceph): This is generally used for Ceph distributed storage systems.

• Port 902 (iss-realsecure) and Port 903 (iss-console-mgr): These are generally associated with ISS RealSecure, a network security software.

• Port 912 (apex-mesh): Generally used for APEX endpoint-to-endpoint communication.

• Port 5357 (wsdapi): Web Services for Devices allows for device discovery on a network. This should be secured appropriately to prevent unauthorized access.

• Filtered Ports: A large number of ports are filtered, most likely by a firewall. This could make it difficult to definitively determine the services running on these ports.

Understanding this Nmap output provides you with a snapshot of the network services running on the machine at IP address 172.25.32.1, and can be a good starting point for security audits or further investigation.
