Secure Remote and Outbound Internet Access Using ISA Server 2006 Web Proxy | 2006-09-06 01:00:12 |
Microsoft |
| |
Almost all companies today have a connection to the Internet that provides access to information on Web servers at partner and customer sites, as well as access to Web content at main offices from branch locations. A popular and powerful solution to the problems of secure Web access is a Web proxy. Web proxy devices help enable a company to control the flow of information moving over Web channels using the HyperText Transfer Protocol (HTTP), Secure HTTP (HTTPS), and File Transfer Protocol (FTP) application protocols. Web proxy servers act as intermediaries between client and server. This white paper explores how ISA Server 2006 provides enhanced security and application acceleration by acting as both forward and reverse Web proxy for the corporate network.

Log Analysis for Intrusion Detection | 2006-07-27 10:07:07 |
Infosecwriters.com |
| |
Log analysis is one of the most overlooked aspects of intrusion detection. Nowadays every desktop is with an antivirus, companies with multiple firewalls and even simple end-users buying the latest security related tools. However, who is watching or monitoring all the information these tools generate? Or even worse, who is watching the web server, mail server or authentication logs? The author explains about the crucial security information that only few of these events have and nobody notices. A lot of attacks would not have happened (or would have been stopped much earlier) if administrators cared to monitor their logs.

Network Measurements of a Wireless Classroom Network | 2006-05-10 01:00:28 |
University of Calgary |
| |
The advent of mobile computers and wireless networks enables the deployment of wireless Web servers and clients in short-lived ad hoc network environments, such as classroom area networks. This paper studies wireless Web performance in a classroom environment. Experiments are conducted on an ad hoc IEEE 802.11b wireless LAN, using a wireless-enabled ApacheWeb server, several wireless clients, and a wireless network analyzer. The experiments focus on the HTTP performance and network throughput achievable in the wireless classroom environment.

Towards the Use of Qualitative Reasoning for Supporting Information Technology Management | 2007-01-23 01:00:26 |
American Association for Artificial Intelligence |
| |
Building up human resources for Information Technology management and improving web services would benefit if causality was taken into account. Indeed, causality is sometimes only implicit in documents or in the everyday practice of companies. This paper discusses the use of qualitative reasoning techniques for managing IT using an implemented simulation model as illustration. The paper argues that having explicit representations of objects, configurations and causal relations typically found in qualitative models may be of great importance for understanding IT systems and useful for training support and operation teams. The paper addresses some disciplines from ITIL by using Qualitative Reasoning (QR) techniques.

Using Dojo and JSON to Build Ajax Applications | 2006-11-29 01:00:19 |
Sun Microsystems |
| |
Ajax in the simplest sense is taken to mean the process of exchanging data between a web server and a web browser using JavaScript on a loaded web page. In the practical sense, it means avoiding browser requests in favor of asynchronous JavaScript processing, thus making the request/response process transparent to the user. To accomplish this, one can either write his own verbose JavaScript code or use already tested and functional libraries such as Dojo. This paper shows how to build Ajax-enabled applications using Dojo and JSON - two very different but complementary technologies that can significantly enhance the interface and usability of web applications.

A Black-Box Approach for Web Application SLA | 2006-08-23 01:00:12 |
Association for Computing Machinery |
| |
Web servers nowadays have to cope with unprecedented amounts of workload, due to increasing popularity and complexity; in particular, dynamically generated content becomes the standard, hence the term Web application. Providing enough resources to sustain these workloads is a grand challenge, thus the application's runtime environment is often trusted to third-party hosting providers. In such context, it is desirable to make sure that hosted applications are guaranteed a predictable level of performance, in other words implement Service-Level Agreements (SLAs). This paper presents an approach to Web application SLA, based on profiling and geared at black-box server components, which allows to express SLAs using application-level metrics, such as request rates.

Evaluating Network Processing Efficiency With Processor Partitioning and Asynchronous I/O | 2007-01-07 01:00:31 |
Association for Computing Machinery |
| |
Applications requiring high-speed TCP/IP processing can easily saturate a modern server. The authors and others have previously suggested alleviating this problem in multiprocessor environments by dedicating a subset of the processors to perform network packet processing. The remaining processors perform only application computation, thus eliminating contention between these functions for processor resources. Applications interact with Packet Processing Engines (PPEs) using an Asynchronous I/O (AIO) programming interface which bypasses the operating system. A key attraction of this overall approach is that it exploits the architectural trend toward greater thread-level parallelism in future systems based on multi-core processors. This paper presents a detailed experimental performance analysis comparing this approach to a best-practice configured Linux baseline system.

The Practical Union of OLAP Analysis and Geographic Mapping | 2006-05-04 03:25:43 |
SAS Institute |
| |
Whether it is product sales, insurance rates, or credit card fraud, multidimensional data often contains a geographic dimension that allows analysis based on varying locations. In many cases, these locations are political boundaries such as country, state, province, or city. In other cases, the locations, or regions, are defined based on business rules such as sales territory, wireless coverage plans, or population-based Designated Market Areas (DMAs). In all cases, these defined regions provide a critical context for On-Line Analytical Processing (OLAP) exploration and reporting. Coupling the power and flexibility of ArcGIS Server 9 with modern OLAP reporting tools, the "A" in "OLAP" has never looked so good.

Unicenter Database Management: Command Center Architecture | 2006-07-04 03:29:32 |
CA (Computer Associates) |
| |
Enterprise IT Management (EITM) is a vision for how to unify and simplify the management of enterprise-wide IT, so that organizations can better manage risk, improve service, control costs, and align IT with business needs. To make this vision a reality, an architectural foundation, a platform, is required that enables the integration and sharing of management processes, data and user interfaces. CA is delivering precisely such an open, service-oriented integration platform that enables rapid time to value for CA solutions. This paper is intended to familiarize one with Unicenter Database Command Center (Unicenter DCC), its architecture and components.

HP Open Source Blueprint: Web Server Based on HP ProLiant and BladeSystem X86_64 Servers and Red Hat Enterprise Linux 4 Update 2 | 2006-05-02 05:54:22 |
|
| |
HP Open Source Middleware Stacks include building block applications, such as the Apache Web server and OpenLDAP directory services; paper describing how to integrate individual components of a technology stack; and consulting services to speed the successful implementation of an open source strategy. Additionally, HP Open Source Support Services provide a single source for industry leading technical support of all the products that HP sells including hardware, operating systems, and open source middleware. This white paper provides a technical blueprint for the implementation of an open source Web server stack. It covers installation of the initial Linux distribution and middleware building blocks, integration of the components and steps for verification of stack functionality.
