EMERGING FIREWALL MANAGEMENT ISSUES

EMERGING FIREWALL MANAGEMENT ISSUES

Firewalls introduce problems of their own. Internet security involves constraints, and users don’t like this. It reminds them that Bad Things can and do happen. Firewalls restrict access to certain services. The vendors of information technology are constantly telling us “anything, anywhere, any time”, and we believe them naively. Of course they forget to tell us we need to log in and out, to memorize our 27 different passwords, not to write them down on a sticky note on our computer screen and so on.

Firewalls can also constitute a traffic bottleneck. They concentrate security in one spot, aggravating the single point of failure phenomenon. The alternatives, however are either no Internet access, or no security, neither of which are acceptable in most organizations

Firewalls protect private local area networks (LANs) from hostile intrusion from the Internet. Consequently, firewall protection allows many LANs to be connected to the Internet where Internet connectivity would otherwise have been too
great a risk.

Firewalls allow network administrators to offer access to specific types of Internet services to selected LAN users. This selectivity is an essential part of any information management program, and involves not only protecting private information assets, but also knowing who has access to what. Privileges can be granted according to job description and need rather than on an all-ornothing basis.

The issue that most firms grapple with is the make-or-buy decision. Until recently, few vendors have offered off-the-shelf firewall systems. Hence, in the past, construction of firewalls required a significant amount of corpo-rate time and effort, and most firewalls were handcrafted by site adminis-trators. With more choice in the marketplace, managers need to be careful in selecting a firewall solution and need to evaluate the trade-off between ease of use, ease of administration, and data security.

Frequently, technical design of the firewall is dictated by financial con-cerns about the costs of buying or implementing a firewall. For example, a complete firewall product may cost anywhere between $0 and $200,000. At the low end, configuring a router will cost staff time. Implementing a high- end firewall with specialized proxy servers might cost several months of programming effort. Managers must also consider the costs of systems management and evaluate firewalls not only in terms of immediate costs, but also in terms of continuing maintenance costs such as support and soft-ware upgrades.

Firewalls also present capacity management problems. For instance, in companies that use the Internet a lot, firewalls represent a potential bottle-neck, since all connections must pass through the firewall and, in some cases, be examined by the firewall.

Finally, firewalls present content management and control problems.
Who manages the information on a firewall?
Is it the function of the MIS department, marketing communications, or should it be left to the func-tional units? This is a tricky problem because for large firms, content man-agement is a function of the marketing communications department, which zealously guards against any effort that may affect the corporate image. In such a scenario, functional units would have to approach marketing com-munications for clearance and approval before placing anything online. The approval process is bottlenecked and could result in delays of several weeks. In the meantime, the functional units are getting worried because the content is getting dated and would have to. be updated the minute it is approved: a classic “Catch 22” situation. Addressing control issues will re-quire serious thinking about delegation of authority, organizational struc-ture, and content management.

Production planning and control in mass production

Production planning and control in mass production Mass production Only one type of product or maximum 2 or 3 type of products are manufactured in large quantities and much emphasis is not given to retail consumer orders. Standardization of products, processes, materials, machines, uninterrupted flow of materials are the main characteristics of this system. Example: - petrochemical industry, cement industry, steel industry, sugar industry, cigarette industry etc. Features of mass production system o It includes manufacturing of high volume standardized products. o There is a smooth flow material from one work station to another workstation. o Production time of production unit as a whole is short (i.e. because of specialization principle). o Closely spaced work station reduce material handling. o Production planning and control is simple. o Work in progress inventory is less. Production planning and control is possible under mass production only with the help of line balan

ELECTRONIC COMMERCE AND ONLINE PUBLISHING

ELECTRONIC COMMERCE AND ONLINE PUBLISHING Electronic Commerce and Online Publishing The Web may have blossomed because of peer-to-peer publishing, but judg-ing from recent product offerings, there is an enormous groundswell of in-terest among both commercial and corporate publishers in the Web. For instance, it was reported that, in less than three months, the Wall Street Journal Interactive Edition attracted 500,000 registered readers on the Web, and that number is growing by some 3,000 readers per day. Also, the elec-tronic edition has attracted more than thirty advertisers paying to reach this audince. Initially, growth in the online publishing marketplace was driven by the potential of new interactive technologies and applications. The promise of new interactive publishing captured the imagination of both content providers and the public. However, from 1993 to 1995 much of online publishing was inhibited by a lack of business purpose. At that time, the con-tent creation s
