b. If no special management directives require computer management by geo graphical, departmental, or functional part of the organization, create OUs for each operating system and create child OUs to represent client computer roles such as laptop, desktop, and administrator workstation as illustrated in Figure 11-2. 3. If GPOs will be filtered by computer group, determine how you will group com puters and design an OU hierarchy that does not cover these groups. Examples of such an OU hierarchy are:

Because this is a bidirectional relationship, the manager knows his or her reports, and also his or her own manager. The Employee class may therefore contain:

you additional flexibility and control when you establish trust in certification authori ties, issue certificates to computers, and deploy the Encrypting File System (EFS) across a domain.

If groups will represent a computer operating system, create an OU infrastruc ture that does not include OUs based on a computer operating system. Instead, add computer accounts to computer groups based on operating sys tem, and filter GPOs by these groups. Figure 11-3 shows this type of hierarchy. If groups will represent a computer role, create an OU infrastructure that does not include OUs based on computer role. Instead, add computer accounts to computer groups based on a computer role, and filter GPOs and the OU level by these groups.

EFS can be controlled and disabled through Group Policy. If you choose to disable EFS for your domain, which prevents users from encrypting files, you can do so by set ting an empty recovery policy at the domain level. Specific directions on how to do this are listed in Microsoft Knowledge Base Article 222022, entitled HOW TO: Disable EFS for All Computers in a Windows 2000-Based Domain, available at http://support.microsoft.com.

The Software Restriction Policies security area is a new feature in Windows XP and Windows Server 2003 used to identify software running in a domain and to control its ability to execute. This feature can identify software that is hostile or unwanted and prevent it from executing on computers running Windows XP Professional and Windows Server 2003. Software restriction policies are discussed in detail in Lesson 2.

/** * Manager of the {@link Employee} */ @ManyToOne private Employee manager; /** * {@link Employee}s reporting to this {@link Employee} */ @OneToMany(mappedBy = "manager") private Collection<Employee> peons;

The IP Security Policies security area is used to configure network Internet Protocol (IP) security.

The following are the best practices for applying security settings:

The entire relationship here is contained within the Employee class. As with all bidirectional relationships, the inverse side specifies mappedBy to indicate the property to act as the owning side. Java Persistence currently requires that the many-to-one side always be the owner. This may seem very confusing, but if you obey the cardinal rule of always wiring both sides of a relationship, then you will have no problems.

Do not configure account policies for OUs that do not contain any computers because OUs that contain only users always receive account policy from the domain. When setting account policies in Active Directory, keep in mind that there can only be one domain account policy: the account policy applied at the root domain of a domain tree. Event log size and log wrapping should be defined to match your organization s business and security requirements. Consider implementing Event Log settings at the site, domain, or OU level to take advantage of Group Policy settings. Track the system services used on a computer. For performance optimization, set unnecessary or unused services to start only by manual intervention. If you choose to set the system service startup to Automatic, perform adequate testing to verify that the services can start without user intervention.
