QUESTION 2
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003 and all client
computers run Windows XP Professional.
The Certkiller .com network also contains a perimeter network. The Certkiller .com
intranet Web site is hosted on a Web server named Certkiller -SR17.
Certkiller -SR17 resides on the perimeter network. Other servers hosted on the
perimeter network, also available to the public, are the company e-mail and FTP
servers.
The Certkiller .com written security policy requires you to secure the most
vulnerable element of all servers hosted on the perimeter network, so as to secure
the Certkiller ,com network from attacks originating from the Internet. You must
implement a solution which will decrease the identified vulnerability. You do not
want to move any public servers to the internal network.
What should you do?
A. Configure Kerberos authentication.
B. Install a firewall and configure packet filtering to filter traffic from the Internet.
C. Install a PKI and digital certificates on your public servers.

Actualtest.org – The Power of Knowing
D. Configure NTFS permissions.
Answer: B
Explanation: The biggest vulnerability you have is that there is no firewall between
the Internet and your perimeter network. This basically means that an attack can
be launched from the Internet to take control your server computers on the
perimeter network. The attacker can then use one of your public servers to access
the corporate network. You can mitigate this risk by implementing a firewall
between your perimeter network and the Internet. You should configure packet
filtering to filter all traffic passing from the Internet to the perimeter network.
Incorrect answers:
A: Kerberos authentication will not stop an attack from the internet.
C: You need to secure the network, and not specifically ensure that data can be encrypted
through SSL or IPSec.
D: NTFS permissions are configured to control access to file system resources. You
should be more concerned with securing your network from attacks from Internet users.
QUESTION 3:
You work as the network administrator at CertKiller.com. The CertKiller.com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the CertKiller.com network run Windows Server 2003 and all client
computers run Windows XP Professional. The CertKiller.com intranet Web site is
hosted on a Web server named Certkiller -SR11.
Users in the Human Resources department make confidential CertKiller.com
employee information available on the CertKiller.com intranet Web site. An
application named App6 is used to enable users to access their personal
information. All personal information resides in a virtual directory folder named
Employee.
The CertKiller.com written security policy only allows employees to access their
specific employee file through the intranet Web site. All information in these files is
confidential. The security policy also requires all employee information to be
encrypted as it is transmitted over the network.
You need to ensure that the two requirements stipulated in the CertKiller.com
written security policy are enforced. You do not want to encrypt all information
available on the intranet Web site, other than the employee information.
What should you do? (Each correct answer presents part of the solution. Choose
TWO.)
A. Configure EFS to encrypt the Employee virtual directory.
B. Configure the Employee virtual directory to require SSL
C. Install a digital certificate on Certkiller -SR11.
D. Configure Certkiller -SR11 to encrypt secure channel data.

Actualtest.org – The Power of Knowing
Answer: B, C
Explanation: To ensure that all employee information is encrypted as it is
transmitted over the network between Certkiller -SR11 and client computers, you
need to firstly install a digital certificate on Certkiller -SR11 and then configure
the Employee virtual directory to require SSL. Secure Socket Layer (SSL) is a
Windows Server 2003 security protocol which utilizes a public-key technology to
provide a secure channel for applications communicating over a non-secure
network such as the Internet. SSL is typically used by Web browsers and Web
servers for secure communication channels. The SSL protocol functions at the OSI
model’s network layer to provide encryption for the following protocols: HTTP,
LDAP, and IMAP.
Incorrect answers:
A: EFS is applied to file systems and not to Web servers. Also, when EFS encrypted data
is transmitted over the network, it sent in the decrypted format.
D: Secure channel is used between domain controllers and domain member computers,
and not between client computers and intranet Web sites.
