Gizmo Databases
Margo Seltzer, Harvard University and Sleepycat Software

Every five years, database researchers meet to identify and discuss the important issues in database research. Most recently, Gizmo databases (databases embedded in devices such as smart cards, toasters, or telephones) were singled out as one of the most important areas for consideration over the next few years. In this talk, I will discuss the unique challenges and considerations inherent in Gizmo databases and how different database systems address those issues. I will also present a summary of the recent panel at the 1999 SIGMOD (Special Interest Group on the Management of Data) conference, which discussed mobile and embedded systems.

Deploying IP Multicast
David Meyer, Cisco Systems

Over the past few years, IP multicast and IP multicast-capable applications have received significant attention. IP multicast infrastructure enables scaling by conserving the bandwidth required by one-to-many applications, such as broadcast Internet Television. In addition, IP multicast has enabled many new applications such as many-to-many video conferencing. This talk will focus on the building blocks of a multicast backbone, including Multicast BGP (MBGP), Multicast Source Discovery Protocol (MSDP), and Sparse Mode PIM, and describe recent experiences in deploying multicast infrastructure.

The Joys of Interpretive Languages: Real Programmers Don't Always Use C
Henry Spencer, SP Systems

Many programmers are far too ready to roll up their sleeves and start writing C (C++, Java, Fortran, etc.) when they should be considering alternatives first. Interpretive languages are often a better way to do things, even fairly ambitious things. Sometimes a certain amount of C (or whatever) is indicated, but even then, often better results can be had with a partnership between primitives written in C and overall control written in something else. This talk will discuss why the instant resort to C is a bad idea, describe some of the alternatives, including mixing solutions, and explain how to make the choice.

E-mail Bombs, Countermeasures, and the Langley Cyber Attack
Tim Bass, Consultant

The robustness of the Sendmail MTA program can be misused in numerous attack scenarios to create dangerously destructive SMTP e-mail bombs. These e-mail bombs are launched by readily available automated software tools which can easily crash chains of SMTP mail servers. SMTP mail relays can also be used covertly to distribute messages and files that could be seriously damaging to the integrity and brands of victims. This talk discusses SMTP mail-bombing techniques, automated attack tools, countermeasures, and "The Langley Cyber Attack."

The speaker, who was the Chief Scientist during the 1997 attack, will discuss the analysis of the cyber attack, graphs illustrating the attack volume, and a statistical e-mail bomb early warning system. Recent anti-spam enhancements to sendmail are compared to the e-mail bomb countermeasures and the "blackhole strategy" used in the Langley Cyber Attack.
