Frequently Asked Questions
What are common network ports?
Examples include 80 for HTTP, 443 for HTTPS, 22 for SSH, 53 for DNS, and 25 for SMTP. Ports let a host run many services at once.
What is the difference between a port and a protocol?
A protocol defines the rules for communication, while a port is a numbered endpoint where a service listens. Protocols usually have default ports.

Unusual ports or exposed services are common attack signs. This free Codelivly room helps you recognize protocols and what normal traffic looks like.
