Internet Plumbing

Internet Plumbing is a word-game with multiple layers of meaning (ha! a recursive pun ;-)

Ubiquitous and complicated as plumbing?

• Internet as a utility
• just like "plumbing" (water & sewage), there is underlying "technology" to it, so complex, that no-one seems to grasp how all of it works
• 60% of the population of the planet does NOT have "teh Internets", and 30% does not have plumbing either (http://www.un.org/waterforlifedecade/sanitation.shtml)

Acronyms!

• TCP/IP
• IPv4, IPv6: Internet Protocol (IP) addresses
• NAT: Network Address Translation
• DNS: Domain Name System
• ASN: Autonomous System Number
  • used for BGP routing (Border Gateway Protocol)
• IXP: Internet eXchange Point
• SMTP
• HTTP
• CDN

Overview

OSI Model T-shirt enhanced to include an 8th and 9th layer as defined by Evi Nemeth: https://en.wikipedia.org/wiki/Evi_Nemeth // https://www.isc.org/product/isc-9-layer-osi-model-cotton-t-shirt/

(TODO: add ISC reference to Evi's wikipedia page!!) 

Description of OSI layers

Borrowed from: https://en.wikipedia.org/wiki/OSI_model

The recommendation X.200 describes seven layers, labeled 1 to 7. Layer 1 is the lowest layer in this model

OSI Model
Layer		Protocol data unit (PDU)	Function<ref>Template:Cite web</ref>	Examples
Host layers	7. Application	Data	High-level APIs, including resource sharing, remote file access, directory services and virtual terminals	TLS, FTP, HTTP, HTTPS, SMTP, SSH, Telnet
	6. Presentation		Translation of data between a networking service and an application; including character encoding, data compression and encryption/decryption	CSS, GIF, HTML, XML, JSON
	5. Session		Managing communication sessions, i.e. continuous exchange of information in the form of multiple back-and-forth transmissions between two nodes	RPC, SCP, NFS, PAP,
	4. Transport	Segment (TCP) / Datagram (UDP)	Reliable transmission of data segments between points on a network, including segmentation, acknowledgement and multiplexing	NBF, TCP, UDP
Media layers	3. Network	Packet	Structuring and managing a multi-node network, including addressing, routing and traffic control	AppleTalk, ICMP, IPsec, IPv4, IPv6
	2. Data link	Frame	Reliable transmission of data frames between two nodes connected by a physical layer	IEEE 802.2, L2TP, LLDP, MAC, PPP, ATM, MPLS
	1. Physical	Bit	Transmission and reception of raw bit streams over a physical medium	DOCSIS, DSL, Ethernet physical layer, ISDN, USB

Layer	Example	Practically	Owner	Developed by	Vulnerabilities/Dangers	Securing	Alternatives
Physical	HW - end user equipment	Computer, tablet, phone...	User	Commercial companies: Apple, Siemens, Samsung...	Un-ethical manufacturing, security backdoors, pollution caused by e-waste disposal,	Hard:	Open HW movement; fair-phone; DIY, Repair Cafes, fair-trade...
