Lesson 6.1: Final mission: map and assess the Northwind office network
The whole course in one job, under a written authorisation: find where you are on the network, discover every host, identify their services and versions, look at the web pages they expose, check the company's DNS, read existing traffic captures for clear-text passwords, rate what you found and deliver a sealed report. Addressing, ports, protocols, services, scanning, packet analysis and firewall thinking, together.

- Write a rated, sealed findings report
Key terms
- Network assessment
- A structured, authorised review of a network: what's on it, what it exposes, how its traffic is protected, and what to fix first.
- Finding
- One issue (or one good practice) with its location, evidence and severity.
- Positive finding
- Something that is done right, recorded so it's kept and so the report is fair.
- Clear-text credential exposure
- A password or other secret seen in readable form in traffic or files. Reported, never used.
