Remote Desktop Level 3 Extended Diploma Unit 13 Computer Systems Architecture

2 Remote desktop Understand usage Understand function
Research security issues Plan measures to improve security Implement the measures (assignment 2 P4 and M2)

3 Usage Remote administration Remote support Training
Controlling “headless” computers no keyboard or monitor attached, no KVM Portable USB drive installations allow remote desktop usage from any PC Connect back to your “home” PC from anywhere

Works with any desktop Initial full frame then changes High bandwidth requirement when many picture changes No encryption in base protocol Can be run from flash drives

7 Methods - RDP Server and client built in to all Windows
Uses kernel level drivers, sends graphics primitives Encrypted Feature rich File redirection – use local files on a remote PC Audio redirection Printer redirection – use local printer Shared clipboard

8 Security What security problems exist?
Permits remote access to administrator accounts Unlimited account access Default ports Windows code security flaws
