Using Context-Based Correlation in Network Operations and Management
No full textNetwork operation consists to a large degree of reaction to activities happening in the network. Better knowledge of the network at any time allows more appropriate reactions. On the example of intrusion detection, we show how context-based correlation of such activities can provide a more detailed view of the network in shorter time. We first present how we model context and then describe the architecture of the Stanford University CEP context-based correlator. Correlation is specified as event patterns in a declarative language that allows us to specify what needs to be detected, instead of specifying how it should be detected. CEP introduces the concept of causal context to intrusion detection. The correlator is able to process events on-line, as they are generated and it can be reconfigured at dynamically. We then show how it increases detection rate, reduce false alarms, and detect large-scale attack pattern at an early stage. Keywords: Network operations and management, correlat..
Translation Servers: Gateways Between Stateless and Stateful Information Systems
No full textPublic information systems offering access to the network community can be divided into two groups: those with stateful protocols and those with stateless protocols. Evolving client-server protocols like the Hypertext Transfer Protocol (HTTP) of the World-Wide Web (W3) are stateless. In this case the reaction of the information server depends on the request only. To access the server, special client programs (browsers) are required. Such browsers are comfortable tools for users, however they cannot access stateful servers directly. For this purpose either additional, stateful client programs or additional servers are required. This paper introduces the concept of Translation Servers, generic gateways to provide uniform and stateless access to stateful information servers for stateless browsers, without restructuring or duplicating the data. To communicate with the stateful information server, the Translation Server accesses the same user interface that has been designed for human use. ..
WAB: World Wide Web Access for Blind And Visually Impaired Computer Users
No full textA blind or visually impaired user can get lost in hyperspace on one single W3-page. This paper presents Web Access for Blind users (WAB), a working system which makes web-surfing easier for blind persons. Normally, structure and meta information in HTML documents are displayed visually and are difficult for blind users to recognize. WAB transforms structure and meta information into a form that can be more easily read by visually handicapped people. Titles, links and form elements are described textually. Special navigation aids allow the blind user to navigate through the title hierarchy as well as through the list of links. The implemented system works with any World-Wide-Web-browser and any screen reader. No additional software has to be installed on the user's computer. KEYWORDS: Blindness and visual impairment, WWW, W3, Proxy Servers, User Interfaces, Document Structure and Formats, `Screen Reader'. 1. INTRODUCTION A sighted user can get an overview of the structure of a World-..
Distributed Method Management with CORBA
No full textThe Internet hosts a rapidly number of services for remote computing. The second generation of services are distributed method management systems (DMMS) that support consumers and providers to participate in electronic markets for methods (programs, scripts, etc.). We suggest to build standardized DMMS based on CORBA, instead of heterogeneous, domain specific solutions. An architecture is proposed and a simple solution to wrap script-like methods into CORBA Application Objects is presented
