The SNMP protocol was introduced in 1988. Overtime security had been added (1991-1992). Also several version improved versions have been published (SNMPv2[1] and SNMPv3[4]) The goal is to allow automation of network management by establishing a standard protocol supported by all network devices for configuration and monitoring.

Using SNMP enabled devices network administrators can automate the tedious and error prone task of changing the configuration of the network by using an administration interface which in turn will automatically re-configure each device on the network using SNMP. By having a unified protocol a single administration application can manage an entire network of heterogeneous devices.

First generation wireless systems, which primarily provide analog voice service, are widely in use worldwide. Second generation systems support digital voice/data traffic; some of these systems are already deployed or undergoing deployment. Third generation wireless networks will ultimately carry multimedia traffic that are characterized by combination of different informaion streams of diverse nature (e.g., voice, video, image, data). Some of the salient features of multimedia applications are high speed and changing bit rates (periodic and bursty arrivals), several virtual connections over the same access, synchronization of different information streams, and various service/deliveIy requirements (QoS).

Everybody who wants to install a web server database but does not know which software is necessary and how it is installed should benefit from reading this text. This text provides all information necessary to get a SQL database for a web server going; it does not go into any detail of CGI programming, nor does it explain the SQL database language. Excellent books are available on both topics, and it is the intention of this text to provide a working platform based on which a user can then study CGI programming and SQL. For getting a small scale SQL system running (not the notorious example of a major airline booking system, or space mission management database) it will be sufficient to have the software described in this text and the documentation accompanying it. The user manual of msql (a database introduced in this text) provides sufficient information on SQL for building your own database.

Many IT organizations view the phrase Web 2.0 as either just marketing hype that is devoid of any meaning or they associate it exclusively with social networking sites such as MySpace. That’s understandable as Web 2.0 is not the same as a new protocol that has an associated RFC that spells out definitively what is and what is not included as part of the protocol. As a result, many concepts get lumped under the banner of Web 2.0. In one of the most insightful analyses of Web 2.0, Tim Reilly points out that Web 2.0 involves fundamentally new design patterns and business models and he compares companies that were successful with Web 1.0 with those companies that are leading the movement to Web 2.0.

With Active Directory, Microsoft has provided administrators with a powerful directory service to organize network data and to control access to network resources from a central point. However, “powerful” by necessity also means complex, and the complexity of Active Directory has probably contributed to slowing down the rollout of Windows 2000 and 2003 servers. Initially, many organizations found simply migrating their flat NT4 domain structures into a more sophisticated Active Directory wrapping to be a significant challenge. By now, many have defined their Active Directory Forests, survived an often cumbersome deployment process, and seen their directories mature into efficient tools for centralized administration. Policies have become the levers of network management, and, as a result, Active Directory has become a repository holding extremely sensitive data.

The networked and increasingly ubiquitous nature of today’s data management services mandates assurances to detect and deter malicious or faulty behavior. This is particularly relevant for outsourced data frameworks in which clients place data management with specialized service providers. Clients are reluctant to place sensitive data under the control of a foreign party without assurances of confidentiality. Additionally, once outsourced, privacy and data access correctness (data integrity and query completeness) become paramount. Today’s solutions are fundamentally insecure and vulnerable to illicit behavior, because they do not handle these dimensions.
