Readings

Readings Note: For the second half of the course, it will be much more important that you actually do the readings before class as assigned. I will assume you have done so in my lectures, and interesting class discussions will depend on you coming in having though about the material in the assigned reading.

Read before Wednesday, 25 October:

• Jerome H. Saltzer and Michael D. Schroeder, The Protection of Information in Computer Systems. Proceedings of the IEEE, September 1975. (Originally in SOSP 1973).

  This is a classic paper on system security which grew out of their work on Multics. Almost all of it is still relevant today.

Read before Monday, 30 October:

• Eugene Spafford, The Internet Worm Program: An Analysis, December 1988.
• Richard Pethia, The Melissa Virus: Inoculating Our Information Technology from Emerging Threats. Testimony before US House Subcommittee on Technology, April 15, 1999.

  As you read these papers, think about what things have changed between 1988 and 1999. How has the damage that can be caused by malicious code changed? How have systems become less vulnerable? How have systems become more vulnerable?

Enjoy your break!

In fact, this administration has begun to transform the American military, to take it away from being a Cold War force, to prepare it to meet the threats of the new generation of tomorrow of weapons of mass destruction, of ballistic missiles, of terrorism, even of cyber-warfare.
