Section Objectives

Understand database security in Microsoft Access

Understand the role of the workgroup information file in Microsoft Access security

Learn how to:– Use the Microsoft Access Security

Wizard to implement basic database security

– Use Microsoft Access security tools to manage database security


Database Security in Access

• Access has a built-in database security system• We run within the security system all the time we use

Access• Access stores the default security settings in a workgroup

information file named system.mwb, located in the Windows system files as C:\WINDOWS\system32\system.mwb

• Other workgroup information files (.mwb files) can be created to secure individual or groups of databases– Before this is done—before any of the steps in this section of

“The Access Workbench” are done—make a backup copy of the original system.mwb file!

– If this file gets corrupted or otherwise messed up, you will have real problems using Access

– Copy the system.mwb file to your My Documents folder.


Access Default Security Settings:The User and Group Accounts Dialog Box

The Admin user account—this is the only user account in the default security system

There are only two groups in the default security system, and Admin is a member of both


Default Database Security in Access

• We have been running Access as Admin with no password and, thus, have had full administrator privileges in Access.

• Access has the ability to handle user authentication by the use of user login and password

• Access also has user authorization capability at the DBMS level

• Access authentication and authorization security settings can also be applied to individual databases


Applying Database Security in Access

• It is easiest to set up database security and to learn the abilities of the security system by using the Access Security Wizard

• This Wizard is inconsistently named within Access and the Wizard itself as the Security Wizard, the User-Level Security Wizard, and the One-step Security Wizard


Access Security Wizard:The User and Group Accounts Dialog Box

Read this carefully!

This means creating a new .mwb file to store security settings for this database. The current file is system.mwb


Access Security Wizard:Creating the Workgroup Information File

Use the default File Name and WID

Type in the Company name

Keep the security settings specific to this database only—a desktop shortcut icon will be generated to use for opening the database


Access Security Wizard:Specifying the Included Database Objects

The Wizard has already selected all objects in the database to be secured


Access Security Wizard: Specifying the Included Security Groups

Select all the groups—we will include all of them


Access Security Wizard:Access Security Group Permissions Summary


Access Security Wizard:Setting Permissions for the Workstation Users Group

Do not give the workstation Users group any default rights to the database


Access Security Wizard:Creating Users

Type the user name here—this will be the user’s login name

Type a password here—this will be the user’s password for login

Click the Add This User to the List button to add a user


Access Security Wizard:Assigning Group Membership to a User

Click this radio button to assign group membership to a user

Select the user name from the drop-down list

Select the groups in which the designated user will have membership


Access Security Wizard:Assigning User Members to a Group

Click this radio button to assign users to groups

Select the group name from the drop-down list

Select the users that will be members of the designated group


Access Security Wizard:The Security Wizard Warning Dialog Box

Click the Yes button to save the One-step Security Wizard Report as a Snapshot (.snp) file


Access Security Wizard:The One-step Security Wizard Report

This is the Snapshot Viewer

Print button on the Scroll Bar


The “You Don’t Have The Necessary Permissions to Use This File” Dialog Box


The Access Login Dialog Box

Enter the user’s login name here

Enter the user’s password here


Security Adminstration:The User and Group Permissions Dialog Box

Permissions should be assigned to groups, not users

Select the Object Type from this drop-down list

Select the User/Group Name in this list

Assign specific permissions here
