The current Wingtip Toys server topology is shown in the following table.
All servers in the Wingtip Toys environment are joined to the wingtiptoys.com domain.

logged.
• Microsoft Word and Microsoft Excel files must be automatically encrypted when
uploaded to the Confidential document library on the Tailspin Toys Microsoft SharePoint
site.
• Multifactor authentication must control access to Tailspin Toys domain controllers.
• All file and folder auditing must capture the reason for access.
• All folder auditing must capture all delete actions for all existing folders and newly
created folders.
• New events must be written to the Security event log in the tailspintoys.com domain
and retained indefinitely.
• Drive X:\ on TT-FILE01 must be encrypted by using Windows BitLocker Drive
Encryption and must automatically unlock.

Explanation:
Security auditing allows you to track the effectiveness of your network defenses and identify
attempts to circumvent them. There are a number of auditing enhancements in Windows Server
2008 R2 and Windows 7 that increase the level of detail in security auditing logs and simplify the
deployment and management of auditing policies.
Auditing policy
Before you implement auditing policy, you must decide which event categories you want to audit.
The auditing settings that you choose for the event categories define your auditing policy. On
member servers and workstations that are joined to a domain, auditing settings for the event
categories are undefined by default. On domain controllers, auditing is turned on by default. By
defining auditing settings for specific event categories, you can create an auditing policy that suits
the security needs of your organization.
Audit Object Access
This security setting determines whether to audit the event of a user accessing an object–for
example, a file, folder, registry key, printer, and so forth–that has its own system access control list
(SACL) specified.
If you define this policy setting, you can specify whether to audit successes, audit failures, or not
audit the event type at all. Success audits generate an audit entry when a user successfully accesses
an object that has an appropriate SACL specified. Failure audits generate an audit entry when a user
unsuccessfully attempts to access an object that has a SACL specified.
To set this value to No auditing, in the Properties dialog box for this policy setting, select the Define
these policy settings check box and clear the Success and Failure check boxes.
Note that you can set a SACL on a file system object using the Security tab in that object’s Properties
dialog box.

Audit Handle Manipulation Group Policy setting
This policy setting determines whether the operating system generates audit events when a handle
to an object is opened or closed. Only objects with configured SACLs generate these events, and only
if the attempted handle operation matches the SACL. Event volume can be high, depending on how
SACLs are configured.
When used together with the Audit File System or Audit Registry policy settings, the Audit Handle
Manipulation policy setting can provide an administrator with useful “reason for access,” audit data
detailing the precise permissions on which the audit event is based. For example, if a file is
configured as a read-only resource but a user attempts to save changes to the file, the audit event
will log not just the event itself but the permissions that were used, or attempted to be used, to save
the file changes.
Global Object Access Auditing Group Policy setting.Global Object Access Auditing. In Windows Server 2008 R2 and Windows 7, administrators can
define computer-wide system access control lists (SACLs) for either the file system or registry. The
specified SACL is then automatically applied to every single object of that type. This can be useful
both for verifying that all critical files, folders, and registry settings on a computer are protected, and
for identifying when an issue with a system resource occurs.
