  1. Telecommunications and Network Physical and Personnel System Application and Individual Planning, Policies, and Procedures Initial Topics • An introduction to information assurance • The threat environment • Risk management • Personnel and physical security

  2. Objectives • Recognize the impact of cyber security in daily activities • Recognize the evolution of information assurance over time • Recognize the fundamental concepts of information assurance

  3. What If… • The sewage system for a major city was compromised? • Spills of raw sewage into a river, parks, and near businesses and homes • Environmental impact to wildlife • Stench for residents • Large cleanup bill • Access to the municipal network and its services were lost • The sewer system was compromised • Rail traffic was halted • The power was shut down • There were problems with a nuclear power plant • A nuclear power plant was compromised? • Railroad service was stopped • Freight and passenger • For a day or more • In 23 states • An electric power plant was compromised? • A major city lost its network for: • E-mail • Law enforcement records • Payroll • Personnel records • Etc. for a week or more?

  4. Who / What Is At Risk? • Organizations: • Transportation – Telecommunications • Medical – Utilities • Government – And more • Devices: • Computers – Phones – Game systems • Cable TV – MP3 players – And more Anyone connected to anyone else.

  5. A Brief History Of Information Assurance • Not a new idea • Greeks circa 480 B.C.E. • Romans (Caesar 100-44 B.C.E.) • Protect information / keep secret • Locks • Fences • Guards • Safes • Couriers Photo by Adam Polselli

  6. Computers • Early • Physical security concerns • Separate computer and communication security • Information transfer by physical means • Multiuser systems • Accounts • Access controls • Remote access (modems) SAGE computer IBM 360 Photos by tomspixels’ http://flickr.com/photos/tomspixels/

  7. Fundamental Concepts Of Information Assurance • Confidentiality • Integrity • Availability

  8. Growth Of Networks • ARPANET • Development of • TCP/IP • Other communication protocols • Evaluating and developing secure systems • Rainbow Series • Common Criteria Image courtesy DARPA

  9. Before The Internet • Bulletin Board Systems (BBSs) • America Online, CompuServe, etc. • Usenet • Need to share information • Tim Berners-Lee developed language to permit sharing of data, including non-text data (HyperText Markup Language (HTML), based on Generalized Markup Language (GML)) • Browser development followed for graphical display of information

  10. The Internet • World Wide Web – name given to the program by Tim Berners-Lee • Growth in number of servers • Platform independent (Windows, X Windows, Mac) • Scripting to allow interaction from pages • Databases providing services through Web interface • As services grow, so do vulnerabilities • More systems connected for convenience

  11. Where Are We Today? Internet Growth • Over 1.5 billion users on the Internet (12/2008) • 5,000 – 8,000 PB (PetaByte = 1015 bytes) of Internet traffic per month worldwide (12/2008) • Traffic growth rate 50-60% per year (12/2008) • Who? • Transportation – Telecommunications • Medical – Utilities • Government – Who else? Data from Internet World Stats, March 2, 2009http://www.internetworldstats.com/emarketing.htm

  12. New Information Assurance Concerns • Information access not controlled by physical means alone • Trespassing • Eavesdropping • Alteration • Theft The CIA triad in a cyber world.

  13. Where This Stuff Came From… • Real world issues caused by computers and networks • Computers are everywhere, supporting daily life • Computers are connected together • Information assurance from Greeks to today • Concepts of • Confidentiality • Integrity • Availability
