Goal(s)

Acquisition of basic networking concepts, awareness of security issues.

Responsible(s)

Clement PERNET, Olivier ALPHAND, Martin HEUSSE

Content(s)

Network section:

• Internet structure, universal network, public address allocation
• Point-to-point link routing
• Layered architecture: ports, addresses
• DNS (and the concept of caching), data and infrastructure structuring
• Concept of URLs
• Description of protocols using state machines
• Performance: frame size, M/M/1 queueing model

Security section:

• Awareness of secure exchanges and data protection
  Basics of cryptography
• Password security
• Authentication and key exchange protocols, security properties
• Authentication/confidentiality/integrity applications in traditional domains: secure email (pgp), browser (certificate, cookie), cloud

3 network practicals: traffic capture, DNS, HTTP;
3 security practicals: secure communication + authentication protocol verification.

*Detailed content (network section)*

-CM1: Internet structure + layered architecture

• • Internet structure: Edge vs. Core, ISP hierarchy, packet switching, transmission and propagation, demo (Ping, Traceroute)
  • Layered architecture: Example of web page loading + segmentation + loss/retransmission, encapsulation, TCP/IP stack
    -CM2: Protocols
  • Protocols: format, order, actions
  • UDP, TCP connection
    -CM3: Layer 3 “Network”
  • IPv4 addressing: hierarchical (subnet) + public address allocation (IANA)
  • Relaying/Routing
    -TD1: Network Performance (Transmission/Propagation, Switching
