Kerberos Interoperability Issues

EBook Description: Kerberos is a secure authentication protocol for use in distributed computing environments. When used ubiquitously within a computing environment it can also provide single sign-on capabilities.

Decisions on implementing IT systems have often been departmental or isolated in nature. As a result many organizations now are faced with the challenge of integrating different networks and computers (in different departments or possibly even within each), each managed by a different operating system, and each running different types of applications

Archipelago: An Island-Based File System for Highly Available and Scalable Internet Services

NT clusters are an important tool for large I/O-intensive applications such as file servers, Web servers, and other Internet services. A wide variety of research projects on cluster file systems have explored approaches to building cluster file systems that provide high availability and scalability.

Publius: A Robust, Tamper-Evident, Censorship-Resistant, and Source Anonymous

We describe a system that we have designed and implemented for publishing content on the web. Our publishing scheme has the property that it is very difficult for any adversary to censor or modify the content

PVFS: A Parallel File System for Linux Clusters

As Linux clusters have matured as platforms for low-cost, high-performance parallel computing, software packages to provide many key services have emerged, especially in areas such as message passing and networking. One area devoid of support, however, has been parallel file systems, which are critical for high-performance I/O on such clusters

Deployme: Tellme's Software and Content Manager

The package philosophy behind these tools is easily extended to rapidly changing content. However, we found these systems to be incomplete because they only cover one or two stages of the package update lifecycle.

IO-Lite: A Unified I/O Buffering and Caching System

For many users, the perceived speed of computing is increasingly dependent on the performance of networked server systems, underscoring the need for high performance servers. Unfortunately, general purpose operating systems provide inadequate support for server applications, leading to poor server performance and increased hardware cost of server systems.

Automatic I/O Hint Generation through Speculative Execution

Many applications, ranging from simple text search utilities to complex databases, issue large numbers of file access requests that cannot always be serviced by in-memory caches. Due to the disparity between processor speeds and disk access times, the execution times of these applications are often dominated by I/O latency

Resource Containers: A New Facility for Resource Management in Server Systems

Networked servers have become one of the most important applications of large computer systems. For many users, the perceived speed of computing is governed by server performance. We are especially interested in the performance of Web servers, since these must often scale to thousands or millions of users.

Intrusion Detection Through Dynamic Software Measurement

The thrust of this paper is to present a new real-time approach to detect aberrant modes of system behavior induced by abnormal and unauthorized system activities. The theoretical foundation for the research program is based on the study of the software internal behavior.

Experience with EMERALD to Date

Anomaly detection involves the recognition of deviations from expected normal behavior, whereas misuse detection involves the detection of various types of misuse. The term ``intrusion detection' is often used to encompass both, but unfortunately suggests only the detection of intrusions rather than the broader scope of EMERALD.
