Question 7: Case 1, Lucerne PublishingOverview
Lucerne Publishing is an industry leader in publishing technology textbooks, e-books, and magazines.
Physical Locations
The company has three offices, as shown in the Physical Locations and Connectivity exhibit.
The company's main office is in New York, and it has branch offices in Denver and Dallas. The company's
employees and departments are distributed as shown in the following table
Business Processes
The IT staff in the New York office uses client computers to remotely administer all Lucerne Publishing
servers and domain controllers. Employees use their company client computers to access archived
published books and archived accounting
information through an internal Web site that runs IIS 6.0.
Directory Services
The company's network consists of a single Active Directory domain named lucernepublishing.com. All
servers run Windows Server 2003, Enterprise Edition. Administration of Active Directory is centralized in
New York. Denver and Dallas user and computer accounts are located in their respective child OUs, as
shown in the Organizational Unit Hierarchy exhibit.
The NYAdmins, ProductionAdmins, EditorialAdmins, and DevelopmentAdmins global user groups have
full control of their respective organizational units (OUs). These global groups are located in their
respective OUs.
Network Infrastructure
All client computers run Windows XP Professional.
The domain contains a public key infrastructure (PKI). The company uses an internal subordinate
enterprise certification authority (CA) to issue certificates to users and computers. Each branch office has
a wireless network that supports desktop and portable client computers. The wireless network
infrastructure in each branch office contains an Internet Authentication Service (IAS) server and wireless
access points that support IEEE 802.1x, RADIUS, and Wired Equivalent Privacy (WEP).
Problem Statements
The following business problems must be considered: Members of the EditorialAdmins group and
unauthorized users as members to this group. Members of this group must be restricted to only
authorized users.
Editors connect to a shared folder named Edits on a member server named Server5. When they attempt
to encrypt data located in Edits, they receive an error message stating that they cannot encrypt data.
Editors need to encrypt data remotely on Server5.
Some users in the Dallas office changed the location of their My Documents folders to shared folders on
servers that do not back up their My Documents data. As a result, data was lost. The Dallas My
Documents folders need to be moved to a server that backs up user data. Users in the Dallas office must
be prevented from changing the location of their My Documents folder in the future.
Chief Information Officer
Security is Lucerne Publishing's primary concern. We must improve security on client computers, servers,
and domain controllers by implementing a secure password policy. For legal reasons, we need a logon
message that tells users that access to servers in the development department is restricted to only
authorized users.
System Administrator
Each department needs different security patches. We need to test security patches prior to deploying
them. After they are tested, the patches need to be deployed automatically to servers in each department.
As we deploy the patches, we need to limit the network bandwidth used to obtain security patches.
Chief Security Officer
We need to automatically track when administrators modify user rights on a server or on a domain
controller and when they modify local security account manager objects on servers.
We must implement the most secure method for authenticating Denver and Dallas users that access the
wireless networks.
We need to protect data as it is sent between the wireless client computers and the wireless access
points. Client computers need to automatically obtain wireless network access security settings.
Written Security Policy
The Lucerne Publishing written security policy includes the following requirements.
Passwords must contain at least seven characters and must not contain all or part of the user's account
name. Passwords must contain uppercase and lowercase letters and numbers. The minimum password
age must be 10 days, and the maximum password age must be 45 days.
Access to data on servers in the production department must be logged.
A standard set of security settings must be deployed to all servers in the development, editorial, and
production departments. These settings must be configured and managed from a central location.
Servers in the domain must be routinely examined for missing security patches and service packs and to
ascertain if any unnecessary services are running.
Services on domain controllers must be controlled from a central location. Which services start
automatically and which administrators have permission to stop and start services must be centrally
managed.
The IIS server must be routinely examined for missing IIS Security patches.
Users of the Web site and the files they download must be tracked. This data must be stored in a
Microsoft SQL Server database.
Vendors and consultants who use Windows 95 or Windows 98 client computers must have the Active
Directory Client Extensions software installed to be able to authenticate to domain controllers on the
company's network.
