Agenda•Chapter 8: Configuring the User and

Computer Environment Using Group Policy

•Quiz•Exercise

Security Settings•Most of the settings are found in the

Windows Settings folder with in the Policies node in the Computer Configuration node of a GPO▫See Table 8-1 on Page 156-157 for more

information

Account Policies•Account policies influence how a user

interacts with a computer or a domain. ▫By default, they are linked to the Default

Domain Policy.•You create one or more Fine-Grained

Password Policies (FGPP) that override the domain-wide policy. ▫A new feature in Windows Server 2008

Account Policies (Cont.)•Prior to Windows Server 2008, you can

configure a single Password Policy and Account Lockout Policy for any Active Directory domain.

Fine-Grained Password Policy•To enable FGPP, you have to create

Password Settings Object (PSO), which also called msds-PasswordSettings

•Each PSO has mandatory attributes:▫Cn▫msDS-PasswordSettingsPrecedence

A tie breaker to determine which PSO should apply

▫msDS-PasswordReversibleEncryptionEnabled To allows passwords to be stored in AD using

reversible encryption▫See full list on Page 160

Kerberos Policy•Default mechanism for authenticating domain

users in Windows Server 2008, 2003, and 2000

•Ticket-based system that allows domain access by using a Key Distribution Center (KDC), which is used to issue Kerberos tickets to users, computers, or network services▫These tickets have a finite lifetime and are

based in part on system time clocks▫Kerberos has a 5-minute clock skew tolerance

between the client and the domain controller. The client will not be able to log on, if time are off by more than 5 minutes

Kerberos Policy (Cont.)•Enforce User Logon Restrictions tells

Windows Server 2008 to validate each request for a session ticket against the rights associated with the user account.

•Enforce User Logon Restrictions is enabled by default.

•See Figure 8-3 on Page 161

Local Policies•Allow administrators to set user privileges

on the local computer that govern what users can do on the computer and determine if these actions are tracked within an event log (auditing):▫User Rights Assignment.▫Security Options.▫Audit Policy.

Audit Policy•Allows administrator to log successful and

failed security events•Planning requires that you determine the

computers to be audited and the type of events you wish to track

Audit Policy (Cont.)• System events — Events that trigger a log entry in

this category include:▫System startups and shutdowns▫System time changes▫System event resources exhaustion, such as when an

event log is filled and can no longer append entries▫Security log cleaning▫Any event that affects system security or the security

log. • In the Default Domain Controllers GPO, this setting

is set to log successes by default

Audit Policy (Cont.)•Policy change events

▫By default, this policy is set to audit successes in the Default Domain Controllers GPO.

▫Triggered by events such as: User rights assignment changes Establishment or removal of trust

relationships IPSec policy agent changes Grants or removals of system access

privileges.

Audit Policy (Cont.)•Account management events

▫Triggers an event that is written based on changes to account properties and group properties.

▫Log entries written due to this policy setting reflect events related to user or group account creation, deletion, renaming, enabling, or disabling.

Audit Policy (Cont.)•Logon events

▫This setting logs events related to successful user log-ons on a computer

▫The event is logged to the Event Viewer Security Log on the computer that processes the request

Audit Policy (Cont.)•Account logon events

▫This setting logs events related to successful user logons to a domain.

▫The event is logged to the domain controller that processes the request. The default setting is to log successes in the Default Domain Controllers GPO.

Audit Policy (Cont.)•Audit Directory Service Access

▫logs user access to Active Directory objects, such as other user objects or OUs.

•Audit Object Access▫logs user access to files, folders, registry

keys, and printers.▫After you enable Audit Object Access, you

need to then specify what you are going to audit

Audit Policy (Cont.)•Events produced by auditing can be

viewed by looking at the Security logs in the Event Viewer.

Restricted Groups Policy•Allows an administrator to specify group

membership lists. ▫You can control membership in important

groups, such as the local Administrators and Backup Operators groups

▫removes group members who are not part of the configured group membership list or adds group members according to a preconfigured list

Folder Redirection Policy•To redirect the contents of certain folders

to a network location or to another location on the user’s local computer ▫Contents of folders on a local computer

located in the Documents and Settings folder, including the Documents, Application Data, Desktop, and Start Menu folders, can be redirected

▫Such as Home drive

Configuring Folder Redirection•If you choose Basic–Redirect Everyone's

Folder To The Same Location▫You must specify the Target folder location

in the Settings dialog box•If you choose Advanced–Specify Locations

For Various User Groups▫You must specify the target folder location

for each group that you add in the Settings dialog box

Offline Files Policy• Allow files to be available to users, even when

the users are disconnected from the network. ▫When the network connection is restored,

changes made to any documents are updated to the server.

▫Folders can be configured so that either all files or only selected files within the folder are available for offline use. When it is combined with Folder Redirection, users have the benefits of being able to redirect files to a network location and still have access to the files when the network connection is not present.

Disk Quotas•Limit the amount of space available on

the server for user data•Required that disk or storage is NTFS•See Figure 8-16 on Page 175

▫Enforce Disk Quota Limit▫Default Quota Limit and Warning Level▫Log Event When Quota Limit Exceeded▫Log Event When Quota Warning Level

Exceeded

Group Policy Refresh•Computer configuration group policies

are refreshed every 90 minutes (+/- 30 minutes) by default.

•Domain controller group policies are refreshed every 2 minutes.

•You can force group policies by using the gpupdate command:

gpupdate /force
