What are advantages and disadvantages of a layered architecture? - Separation of concerns among logical layers promotes flexibility, scalibility, and maintainability. Multiple applications can reuse the components. It enables teams to work on different parts with minimal dependencies on other teams What are the similarities of the OSI model and five-layered Internet model? - They are both based on layered architecture. The are comparable to each other - see image 1 Both are networking stand...

A1) Benefits of pentesting - Manage risk. Increase business continuity. Minimise client-side attacks. Protect clients, partners and third-parties. Comply with regulation. A1) Pentest structure - Reconnaissance (i.e. find live hosts, sweeping, find services, scanning, banner matching, find vulnerabilities). Target prioritisation (e.g. assess servers rather than printers). Testing of services and exploitation if applicable. Consult/Confirm with customer if ok to exploit. Inform customer of any ...
