You are a security administrator for your company. The network consists of a single Active Directory domain. All servers run Windows Server 2003. All client computers run Windows XP Professional. All computers are members of the domain.

The network contains 10 Active Directory sites. Each site represents one of the company’s offices. The offices are located around the world. Each office has a connection to the lnternet. The company maintains dedicated leased lines between the offices. You are planning a security patch management infrastructure for Microsoft security patches. You install Software Update Services (SUS) on a server named Server1. You need to ensure that Automatic Updates on the client computers and servers installs only security patches that are company approved.

You want to limit the use of the leased lines between the offices by allowing each computer to download the security patches from the lnternet. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are a security administrator for your company. The network consists of a single Active Directory domain. All servers run Windows Server 2003. All client computers run Windows XP Professional.

The company occasionally experiences downtime because of malicious lnternet worms that arrive as Microsoft Visual Basic Scripting Edition (VBS) files. You examine several client computers and discover that VBS files are downloaded by using Microsoft Outlook, instant messaging, or peer-to-peer file sharing programs.

You need to prevent users from running VBS files regardless of how they arrive on client computers. What should you do?

You are a security administrator for your company. The company has one main office and five branch offices. Network administrators work in the main office and each branch office.

Network administrators in the main office frequently create scripts that automate common administrative tasks. You review each script to ensure it does not introduce security vulnerabilities. Scripts that do not introduce security vulnerabilities are considered approved. Occasionally, branch office administrators modify these scripts and distribute the modified scripts to other branch office administrators. Branch office administrators often report that they accidentally run a modified version of a script.

You need to ensure that branch office administrators can verify which scripts are approved scripts. What should you do?

You are a security administrator for your company. The network consists of three Active Directory domains. All Active Directory domains are running at a Windows Server 2003 mode functionality level.

Employees in the editorial department of your company need access to resources on file servers that are in each of the Active Directory domains. Each Active Directory domain in the company contains at least one editorial department employee user account.

You need to create a single group named Company Editors that contains all editorial department employee user accounts and that has access to the resources on file server computers. What should you do?

You are a security administrator for your company. The network consists of a single Active Directory domain. The network contains Windows XP Professional client computers and Windows Server 2003 computers.

You install Certificate Services to issue certificates to employees for secure e-mail encryption and Web site authentication. You revoke the certificates used by an employee when that employee leaves the company. Several thousand certificates are currently revoked, and multiple revocations occur daily. Company e-mail and Web applications already use strong revocation checking of certificates. You need to reduce the time that it takes for client computers to find out about certificate revocations and to process certificate revocation information.

You also need to limit the negative impacts that this change will have on network performance. What should you do?
