SECURITY IN A WIDE AREA NETWORK: A TRADE OFF BETWEEN EXPENSES AND
Development Networking Programme in Bangladesh involves integration of
contemporary information technology methods for providing Internet
services to the distant communities with state-of-the-art connectivity
through forming a virtual wide area network. In respect of diversity the
network could be termed as a fusion of high and low end communication
on Linux server, the backbone constitutes of dial-up leased line, VSAT
link, and wireless nodes to high-speed broadband communication network.
This network in a short time would emerge as one the main IT
infrastructure, contributing facilities to urban communities and clusters
of remote communities accompanied by information on emerging technologies,
constricting digital divide. Remote regional nodes would be the vital
places for information gateway to enrich the society from email, updated
databases on livelihood requirements, ingredients of electronics commerce
to web-based database management.
whole network could be spreading throughout the country with robust
connectivity and in course of time it would extend further in
collaboration with other institutes forming the remote nodal points to
virtual tele-centres comprising of computer oriented connectivity, web
services and community based radio station and other ICT facilities. The
network would solely standing alone without any sort of network security
policy. A cost-effective robust WAN would be the prime demand at current
stage, but a reliable secured system would also be the next priority.
Considering high cost of implementation and lack of skilled techniques,
network security would becoming less important in general sense, thus
putting this huge network in a fragile state of un-synchronization, which
ultimately needs a tradeoff between reliability, expense, efficiency and
