Technical background

What is a port/service object?

A port object (service object) names a protocol and port number or range. It maps to Layer 4 (Transport) — TCP, UDP, or ICMP — so rules can allow HTTPS (TCP/443) without permitting all TCP traffic.

Common well-known ports

Security relevance

Combining address + port objects creates precise ACL entries. For example: Source: LAN, Destination: DMZ_Mail, Port: SMTP allows only mail relay traffic, blocking lateral movement on other ports.
