Access control The granting of specific levels of access based on a user s iden tity. Access control capabilities are built into most network operating systems and applications. Auditing A process by which administrators monitor system and network activ ities over extended periods. Most network operating systems and applications include some form of auditing that administrators can configure to their needs. Authentication The verification of a user s identity before providing access to secured resources. Authentication mechanisms can use encrypted passwords, cer tificates, and hardware devices such as smart cards and biometric sensors, depending on the degree of security required.

Microsoft Office Access 2003 Inside Out After making final adjustments to the TrialVersion label, click the Form View button to see the result. Your form should look like the one shown in Figure 11-33. One of the interesting side effects of using a special control to display data in a form is that the control properties carry over to Datasheet view. Switch to the Datasheet view of this form. The CategoryDescription field is displayed as a drop-down list on the datasheet and the TrialVersion field still looks like a check box. You might decide to design some forms to be used in Datasheet view, but you can customize the look of the datasheet by using controls other than text boxes while in Design view. By the way, this design sample is saved as fxmplProducts3 in the sample database.

Encryption The process of protecting data through the application of a crypto graphic algorithm that uses keys to encrypt and decrypt data. The strength of an encryption mechanism is based on the capabilities of the algorithm itself, the num ber and types of keys the system uses, and the method of distributing the keys. Firewalls A system designed to prevent unauthorized access to a private network from outside. Firewalls can use a variety of mechanisms to secure a network, including packet filtering, network address translation, application gateways, and proxy servers.

By now, you should be getting a feel for the process of building forms. In the next chapter, you ll learn how to customize the appearance of your forms.

The security plan is not just a matter of technology. Your security team is also respon sible for creating security policies for the organization. For example, you might agree to use encrypted passwords for user authentication, but you must also decide who is going to supply the passwords, how long the passwords should be, how often they should change, and so forth.

technologies when it implements applications Tailspin s plan is to gain a competitive advantage as an early adopter of new technologies, especially in mobile devices and the cloud It hopes to rapidly gain some experience, and then quickly expand on what it learns This strategy can be described as try, fail fast, learn, and then try again Tailspin has decided to start with the Surveys mobile client application as its first Windows Phone 7 offering The Surveys application has been a great success for Tailspin, but Tailspin wanted to further improve its market position by extending the application s functionality Based on feedback from its subscribers, Tailspin identified four key areas where they could enhance the Surveys application: 1 The application should support a wider range of question types and enable respondents to include additional data, such as pictures, audio, and location data, as a part of their survey responses.

In 11, Building a Form, you created a form from scratch based on the tblCompanies table in the ContactsDataCopy.mdb sample database. You also had a chance to build a simple form on tblProducts using a wizard. These forms are functional, but they re not yet professional grade. In this chapter, you ll learn how to customize your forms to make them more attractive and useful. Note
