To set up a security and information sharing model for the company, it will be much better to utilize a manager security structure through Active Directory than through Workgroups. The reason for this is that there are many different departments within the company. Some information should only be available to specific users within various departments (such as managers). Other information should be available to all employees (employee handbooks, calendars, etc) and still other information should be accessible to only certain groups of people in specific departments (accounting, payroll, etc.)
By instituting a managed security structure, it will be much easier to manage the access to resources and the addition or removal of users and/or access to these resources as the company grows and changes.

The file/print/application architecture will be a client/server architecture so that the management of access to information and resources is in the hands of the network administrator as opposed to the individual users. This is an obvious security measure in any company dealing with sensitive information which should not be shared with all employees. Also this will create a centralized management system for the access to information and resources, making it easier to institute changes across the board.

It would be very beneficial to create security group memberships in Active Directory, for the centralized and timely management of security. Simple changes to the security groups could allow or disallow access to sensitive data for individuals or groups, and could be done instantaneously. Also, this type of security management allows for changes to be made in a more efficient way compared to manual creation of security for certain files and folders.

To ensure that security is maintained, it would be critical to plan the different groups, group membership, access
