Web Hosting — The Security Risks

A company’s website is critical to it’s business. It relies on the site to provide information to its customers — as an interface to communicate with them or sell goods online. As such, it needs to be available 24 hours a day, seven days a week, providing a lightening fast response with first grade security. These things cannot always be achieved without a significant up-front investment and huge on-going costs. For many organizations it is a lot to take on. Unless a company has in-depth internal technical resources, outsourcing may be the way to go. Outsourcing promises to reduce the expense and eliminate many of the headaches associated with running an active and successful website.     

The effects of relationship benefit on relationship quality and store loyalty from convergence environments—NPS analysis and moderating effects

The primary concern of CRM is core customers from convergence environments. They show such passionate partnership with the company that they actively put forth their opinion to improve products and service through voluntary pro-company activities and participate in the development of new products through open innovation. Therefore, the top priority of a company should be given to defining its core customers and accurately understanding and managing them, which would contribute to the growth of the company. This study has the purpose to identify net promoter score (NPS) of company by adopting index that evaluates the degree of customer loyalty to the company in judging the relationship of company and customer, and later on establish strategy to increase the number of loyal customers by classifying customers by the score. It has become more important nowadays how to manage a long-term customer relationship, for it can assure the company of increased income in spite of steep competition with rival companies. Therefore strong customer relationship is an important means of proving the company with competitive edge and maximizing company income. In addition, as NPS serves as adjustment variable, net promoters were analyzed to contribute to store loyalty significantly. The way for bookstore ‘A’ to grow as a company with potential for future growth would be re-establish customers through one more in-depth analysis of customers as well as seek for methods to raise NPS.

Selecting prospects for cross-selling financial products using multivariate credibility

Insurance policies or credit instruments are financial products that involve a long-term relationship between the customer and the company. For many companies a possible way to expand its business is to sell more products to preferred customers in its portfolio. Data on the customers’ past behaviour is stored in the company’s database and these data can be used to assess whether or not more products should be offered to a specific customer. In particular, data on past claiming history, for insurance products, or past information on defaulting, for banking products, can be useful for determining how the client is expected to behave in other financial products. This study implements a method for using historical information of each individual customer, and the portfolio as a whole, to select a target group of customers to whom it would be interesting to offer more products. This research can help to improve marketing to existing customers and to earn higher profits for the company.     

Four ways to improve security

How can you tell if an IT security product (or a product that includes security components) can secure your application? How can you be certain that a product will fully deliver on its claims that it will protect against malice in a deployed environment? Unfortunately, few vendors - and even fewer customers - can make these judgments. The article won't make you a security wizard, but it will give you a feel for what to look for in, and when to be concerned about, a vendor's claims. To ensure that a product has a chance of being secure; customers should check that vendors use adequate approaches in four primary areas. In order of importance (and maturity and availability), they are: quality-control (QC) mechanisms; cryptographic primitives; hardware assist mechanisms; and separation mechanisms.
