Securing and Administering Access
This chapter addresses the issue of database privacy, integrity, and security. The main purpose for database security is to prevent both inadvertent and intentional damage to the data and the database objects. Proper security measures prevent anyone who might view or edit the information from gaining unauthorized access. They also prevent anyone from making design changes without express permission to do so. You can protect both the data and the design elements with a variety of approaches.

Enabling/Disabling controls, based on User Security
In conjunction with using security work groups to limit/permit functionality to individual users, controls may be enabled/ disabled at run time. Otherwise users will have to view a warning message box from Access, when they try to do something they're not allowed to do. Learn how to enable/disable controls on a form in a Microsoft Access database, depending on the security permissions of the current user.

Microsoft Access Security
Microsoft Access allows you to implement security on your database objects as you need it. By default, security is completely invisible to both the designers and the users of an Access database. As your needs require it, you can secure individual objects so that, for example, most users can't modify a particular form. If you are extremely concerned about security, you can use Access to remove all but a few ways to retrieve data from your tables. In networked applications, a well-designed security system can help make the application more maintainable by eliminating many sources of potential disaster.

Database Security
In this tutorial we discuss database security. We specifically look at various SQL statements and constructs that enable you to administer and effectively manage a relational database. Like many other topics you have studied thus far, how a database management system implements security varies widely among products. We focus on the popular database product Oracle7 to introduce this topic. By the end of the day, you will understand and be able to do the following: Create users, Change passwords, Create roles, Use views for security purposes and Use synonyms in place of views.

Create and manage custom categories and groups in the Navigation Pane
Microsoft Office Access 2007 provides a new feature called the Navigation Pane. The pane replaces an older tool - the Database window. You use the Navigation Pane to start and manage the objects in a database - the tables, forms, queries, and so on. You can also use the Navigation Pane in place of switchboards. To do so, you create custom categories and groups that provide shortcuts to only the objects that you want users to see. The information in this topic explains how to create and manage custom categories and groups in the Navigation Pane.

Input validation with VBA
In this article we will look at several methods of validating user input. Why is user input validation necessary? It is necessary for both security reasons and also for the smooth running of your Microsoft Access application. Since Access databases are now commonly used as database backend for websites, it is even more critical to look at security since we don't want unauthorized users to get access to information contained in a database or for users to input data that is not correct.

Password Protect Buttons in Your MS-Access Forms
Security is a very large subject relating to Microsoft Access. There are many, many different ways to implement security and ensuring that your users have access to only what they are allowed to see.

Encrypt a database by using a database password
When you want to help prevent unauthorized use of an Access database, consider encrypting the database by setting a password. If you know the password for an encrypted database, you can also decrypt the database and remove its password. This article explains how to encrypt a database by using a database password, and how to decrypt a database and remove its password. In earlier versions of Access, you could create user accounts and passwords using a feature called user-level security. This topic does not discuss user-level security, which is not available when you use the .accdb file format.

Access 2007 Security Options
Security has always been an important part of database programs, and it is important for users of the new Microsoft Access 2007 database program to take a good look at the ways in which security has been changed and enhanced in this new version. The new Access 2007 allows database developers the ability to quickly and easily lock down their creations without sacrificing the user friendly features of the program. The ability to enhance security is one of the most powerful features of the program, and one that database administrators and other IT professionals will definitely appreciate.

Microsoft Access Database Security
To control what an individual user or group of users can do with database objects, you can secure a Microsoft Access database. As you create database objects, you might consider who will use them and what types of activities the users should be allowed to perform with the objects. These activities might include viewing, modifying or deleting database objects or information. Database security is primarily an issue in a multi-user environment, although you can also secure databases that are stored on a single-user computer.

Who is online
As we already knew we can install Access Database on a Local Area Network (LAN) and several Users can work on it at the same time. But it is difficult to know how many users are actually online with the Application at a given time. Similarly, when there are several MS-Access Databases on a Network under a centrally controlled Security Workgroup it will be interesting to know which users are currently working on the MS-Access Applications on the Network.

Create, remove, or change a trusted location for your files
A trusted location is typically a folder on your hard disk or a network share. Any file that you put in a trusted location can be opened without being checked by the Trust Center security feature. This article explains why trusted locations can be useful and how you create them. It also outlines precautions that you should take before using a trusted location. In this article * When should I use a trusted location? * Which trusted locations are safer? * Create a trusted location * Remove a trusted location * Change a trusted location

Frequently asked questions about Access security warnings
Why does Access display these security warnings? Why does the message "Security Warning: Unsafe expressions are not blocked" appear when I open a file in Access? I have installed the Microsoft Jet service pack. Now when I restart Access and open a file, I see another message that asks me if I want to block unsafe expressions. Why? I enabled sandbox mode, but now it looks as if my application is not working properly. Why? Is enabling sandbox mode the only way to hide this message? What if I don't want to enable sandbox mode? In addition to blocking harmful functions and properties, Access blocks the harmless CurDir and Environ functions in sandbox mode. Access also blocks all the custom properties of ActiveX controls in sandbox mode. Why? I have installed the Jet service pack and clicked Yes when prompted to block unsafe expressions. Now I see the "This file may not be safe" or the "Cannot open file due to security restrictions" warning. Why do these messages still appear? Why does the "This file may not be safe" message appear when I open my file in Access? I see a message that says "Access cannot open the file due to security restrictions. Security settings restrict access to the file because it is not digitally signed." Why? When I open a file, I see the message "This publisher has not been authenticated and therefore could be imitated. Do not trust these credentials." Why? When I open a file, I see the message "This file has been digitally signed by (publisher). The file may not be safe if it contains code that was intended to harm your computer." Why? Often, when I view or change the macro security level, Access prompts me about enabling sandbox mode. Why? My users are complaining about the warnings that appear each time they open one of my databases. Some users cannot even open the database. Why can't I turn off these messages for them? At the High macro security level, I can't open my own databases. At the Medium security level, I can't open my own databases without seeing the "This file not be safe" warning each time I open them. Why? I created this database and wrote some code. But the code does not do anything malicious. Then, why warn me every time? My system is very secure. My computer is not part of a network, and I alone use my databases. Is it okay if I set the macro security level to Low in Access to avoid these messages? Should I set the macro security level in Access to High or Medium? What difference does it make when I open a file? Do I have to buy a certificate to prevent the "This file may not be safe" warning from appearing?

Remove a filter
This topic explains how you can remove a filter to view all records in a view, and to permanently remove filters saved with an object or view. Remove a filter either to see all records or to apply a set of filters that are different from the currently applied filters. Note that you cannot remove just a portion of a filter. In other words, if you filter by City and then by Date, you cannot remove the filter only on the Date field or on the City field. To filter by only one field, you must remove the entire filter and then apply a new filter based on just that one field.

Forms, Access Databases and ASP Code
I have been working on this site for a while now, and there are a few things that I will need to do that I am unsure of. The first is that I want the users instead of Registering, to take a survey, at the end of which they will have been registered. To do this I want to keep the Survey Data, and the User Data Separate. I have below the Form Page, and the Submission page, cutting out the name of the database for security reasons. I need the data from the form, on submission to go into 2 table fields, and it's giving me some trouble. Worst of all, I would like to reference the Users ID Number, userid, from the "Users" Table, into the "Survey" Tables field userid. Among the many errors, I'm thinking there is an easier way to do all this than what I have done. Help is greatly appreciated

Converting a Microsoft Access Database to an MDE File
The situation may arise when you quickly need to secure and distribute a Microsoft Access database that also contains Microsoft Access VBA code. You will protect the database from editing by restricting the database users access to the design views, however you will need to allow the users to process their data as normal. It may be that you haven't got the time to fully create Microsoft Access User Accounts or to set Microsoft Access Security Permissions. By knowing what can and cannot be done by using the Microsoft Access MDE file format, will allow you to make a decision and to quickly release a secure database to the users.

Create a security group account
As part of securing a database, you can create group accounts in your Microsoft access workgroup that you use to assign a common set of permissions to multiple users.

Access Security
The Jet database engine employs a user level security system. In a manner similar to Windows NT and NetWare network security, the objects themselves do not have passwords assigned, but have permissions granted to user and group accounts. Once validated, a user will have the authority to do whatever is authorized by the permissions granted to the user account or to any group of which the user is a member. This permits an administrator to manage a very granular set of security attributes where, for example, an individual user may have the authority to read but not write data. Although the security model does not have the ability to assign column level permissions, through the use of queries and the "run with owner permissions" attribute, you can effectively handle permissions at the row and column level for data.

What happened to user-level security?
User-level security features are not available in databases that use one of the new file formats (.accdb, .accde, .accdc, .accdr). Because user-level security is not supported by the new file formats in Microsoft Office Access 2007.

View my options and settings in the Trust Center
The Trust Center is where you can find security and privacy settings for the 2007 Microsoft Office system programs. The Very High, High, Medium, and Low security levels that were used in earlier versions of Office are now replaced with a more streamlined security system.

Merge groups
When you merge two groups on a data access page, Microsoft Access moves the controls in the group header and group footer of the selected group level into the header and footer of the next lower group level.

Alternating Report Group Colours in a Microsoft Access Report
As we have seen in a previous Microsoft Access report article, we can alternate row colors in our Access reports. You can also add grouping to your report, which breaks related data into groups of records. We can format the report, and alternate the colours of the groups of data, which in turn will greatly aid the user who is viewing the report, by ensuring that the data is in a much more visible format.

File Management
Each table, query, form, and report is a database object that you can copy, rename, create a description of, and set properties for. You can create database objects by importing them from another Access database. You can create tables in Access by importing them from or linking them to another data source. You can import as well as export files. To keep your database in good shape, you need to work with several procedures. Backing up your data is the most important of these operations; however, compacting the database and repairing will be necessary at times. If you are on a network with multiple users, you may want to explore replication to decrease network traffic while still updating your databases. With multiple users, you also need to consider security--that is, who should and who should not have access to the database file and the objects inside.
