What is Host-Based Firewall?

A Host-Based Firewall (HBF) is a software firewall that runs on an individual endpoint or server and enforces network traffic controls for that specific host based on configured rules and policies. Expanded Explanation 1. Technical Function and Core Characteristics A HBF monitors and filters inbound and outbound network traffic for a single Operating System (OS) instance, such as a workstation, server, or Virtual Machine (VM). It applies rule sets that evaluate packet attributes like protocol,

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Host-Based Firewall for a real decision: a shortlist, a vendor comparison, a purchase. "Host-Based Firewall makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
