Network security is an issue for companies regardless of whether they participate in electronic commerce; however, since most organizations have a Web site that allows some interaction with outside individuals, that perspective will be used for the purposes of this analysis. Network security has to be concerned along with protecting the integrity of the data used by the company for its operations. Sales, costs, customer information, and similar data must be precise in order for the company to be able to function at even the most rudimentary level. This means that if the company sells 10 units for $37 per unit, it is recorded accurately as a sale of $370, recorded in accounts receivable appropriately, set up for delivery based on the contract, and have inventory quantities adjusted, as well. This is occasionally considered as data integrity (Smith n.p.). At the same time, that information must be kept secure from prying eyes, or from individuals with more nefarious purposes. Companies want to keep competitors from learning information about the company's operations, and they have a responsibility to their vendors and their customers to keep that information secure. This is important when companies are dealing with other companies in a business-to-business environment, but can be even more critical when companies are dealing with the public through Internet sales. If a company is unable to protect the security or the privacy of its Internet customers, those customers are likely to move to other Internet sites in order to transact their business. Similarly, consumers may be concerned that their personal information is being sold to other companies with whom they may not have a business relationship; as a result, privacy policies have become an important part of network security (Smith n.p.).
