EECS 4482 - Network Security
• What this course is (and is NOT) about …→ todays computers (servers, desktops, laptops, …) are very
smart & capable→ however, stand-alone computers are not nearly as capable
and useful as when they are connected / networked → through networking computers can: exchange information/data combine their processing & memory capabilities
The whole is greater than the
sum of its parts!

EECS 4482 - Network Security
• What this course is (and is NOT) about …→ What is required for 2 computers to be ‘networked’ (i.e.,
to be able to communicate with each other) ?? physical infrastructure (transmission medium, routers, …) protocols = defines rules & conventions for communication
between network devices
Hey, let us network!
Hi, how are you?
Good, and you?
This course is mostly about identifying & fixing security vulnerabilities in communication protocols and network infrastructure.
What you ideally need to know …
• What, really, is a protocol?→ protocol = communication language between peer entities→ packets = sentences
Protocol Syntax & Semantics Protocol Timing
• How many protocols are there?
