COPYING PROHIBITED www.sybex.com 268 Chapter 7  Managing Security Summary In this chapter, you learned how to define security for Windows XP Professional. We covered the following topics:  The difference between LGPOs, which are applied at the local level, and GPOs, which are applied through a Windows 2000 or Windows 2003 domain, and how they are applied.  Account policies, which control the logon process. The two types of account policies are password and account lockout policies.  Local policies, which control what a user can do at the computer. The three types of local policies are audit, user rights, and security options policies.  How to manage security through the Security Configuration and Analysis tool.  How to use the Group Policy Result Tool to analyze current configuration settings. Exam Essentials Understand how group policies are applied locally and through the Active Directory. Know how group policies can be applied either locally through LGPOs or through the Active Direc- tory with GPOs. Understand how group policy is applied through the order of inheritance. Be able to use the Group Policy Result Tool to view how group policy is currently configured for a specific computer. Set up a security configuration based on network requirements. Define the options that can be configured for secure network environments. Know where to configure each option. Know how to set local group policies.

COPYING PROHIBITED www.sybex.com 274 Chapter 7  Managing Security Answers to Review Questions 1. B. Account lockout policies, a subset of account policies, are used to specify options that prevent a user from attempting multiple failed logon attempts. If the Account Lockout Threshold value is exceeded, the account will be locked. The account can be reset based on a specified amount of time, or through Administrator intervention. 2. A. The System Group Policy Result Tool is accessed through the GPResult.exe command-line utility. The GPResult.exe command displays the resulting set of policies that were enforced on the computer and the specified user during the logon process. 3. A. Audit Account Logon Events is used to track when a user logs on, logs off, or makes a network connection. You can configure auditing for success or failure and audited events can be tracked through Event Viewer. 4. D. The Load and Unload Device Drivers user right allows a user to dynamically unload and load Plug and Play device drivers. You could allow a user to complete this task through Administrator or Power User group membership, but by assigning user rights, you can better control security access. 5. B. The Log On as a Service user right allows a service to log on in order to run the specific service. This user right can be assigned to users or groups. 6. B. The security option Do Not Display Last User Name is used to prevent the last username in the logon screen from being displayed in the logon dialog box. This option is commonly used in environments where computers are used publicly. 7. D. Once auditing has been configured, you can see the results of the audit through the Security log in the Event Viewer utility. In order to view the security logs, you must be a member of the Administrators group or have appropriate user rights to view or manage the audit logs. 8. D. The Restore Files and Directories user right allows a user to restore files and directories, regardless of file and directory permissions. Assigning this user right is an alternative to making a user a member of the Backup Operators group. 9. B. The Enforce Password History policy allows the system to keep track of a user’s password history for up to 24 passwords. This prevents a user from using the same password over and over again. 10. Local Computer Site Domain OU By default, GPOs are applied in the order of local computer, site, domain, and OU. The policies will be combined unless conflicting settings are applied, in which case the last policy that is applied contains the effective setting.

COPYING PROHIBITED www.sybex.com Answers to Review Questions 275 11. A. You should just configure a specific GPO so that the file signature verification is set to Warn as opposed to Block, which will refuse upgrading of the driver if it is unsigned without any user notification. The last GPO applied is the domain’s, so you should edit the Sales domain’s GPO for this arrangement. 12. B. The No Override option is used to specify that child containers can’t override the policy settings of higher-level GPOs. In this case, the order of precedence would be as follows: Site would override Domain, and Domain would override OU. The No Override option can be used if you want to set corporate-wide policies and do not want to give administrators of lower-level containers the capability to override your settings. This option can be set on a per-container basis as needed. 13. A, B. The Security Configuration and Analysis tool and the Secedit command-line utility can be used to apply security templates. The Security Templates MMC snap-in is used to create and modify templates. 14. D. By default, Windows XP Professional ships with a variety of predefined security templates. You create security templates through the Security Templates snap-in in the MMC. 15. D. The compatws.inf template is used for backward compatibility. This template relaxes the security used by Windows XP so that applications that are not certified to work with Windows XP can still run. This template is typically associated with computers that have been upgraded and are having problems running applications that have run in the past.
