Question

After running an nmap scan of a system, you receive scan data that indicates the following three ports are open: 22/TCP, 443/TCP, and 1521/TCP. What services commonly run on these ports?

Answer 1

The open ports 22/TCP, 443/TCP, and 1521/TCP are commonly associated with Secure Shell (SSH) for secure data communication, HTTPS for secure web browsing, and Oracle Database for database communications, respectively.

Step-by-step explanation:

After running an nmap scan, the open ports you have encountered, 22/TCP, 443/TCP, and 1521/TCP, commonly correspond to specific services. Port 22/TCP is typically used for Secure Shell (SSH), which is a network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services. Port 443/TCP is well-known for handling HTTPS connections, which provide secure web browsing through SSL or TLS encryption. Lastly, port 1521/TCP is frequently associated with Oracle Database communications. Organizations use these ports to ensure secured data transmission and management of database applications. Remember that while these ports often correspond to these services, it is always important to verify the exact services running on a system as other services can also be configured to use these ports.
