| 9. You are the security analyst for Alecnet . The network consists of a single Active Directory domain Alecnet .com. All servers run Windows Server 2003. The network currently does not have a connection to the Internet. You are in the process of designing an Internet connection solution for Alecnet . Alecnet 's Internet security policy includes the following requirements: 1. Traffic that originates from outside the Alecnet network must never be passed to the Alecnet intranet. 2. Internal Alecnet resources must not be directly accessible from the Internet. 3. Alecnet 's public Web site must not contain any confidential Alecnet information. 4. Alecnet 's public Web site must be accessible from the Internet, even in the event of the failure of any Alecnet -owned network component. You design a network solution that provides strict access control to the Alecnet intranet by means of a firewall. Your new design includes a perimeter network, which contains resources that external users or computers might need to access. Your design also includes three computers running intrusion-detection software: ISD1, IDS2, and IDS3. You now need to plan the placement of five servers on the network in accordance with Alecnet 's Internet security policy. How should you place the servers to comply with the security policy? To answer, drag the appropriate server role to the correct network location in the Network Diagram. Explanation: We must ensure that traffic from outside the Alecnet network never passes to the Alecnet intranet and that internal Alecnet resources aren't directly accessible from the Internet. In addition, the public Web site must be accessible from the Internet even in the event of the failure of any Alecnet -owned network component. To ensure that traffic from outside the Alecnet network never passes to the Alecnet intranet but can access the public web site, we should place the Web server outside the firewall. For security reasons, services that require access to the Internet should be placed in the perimeter network. These include Email forwarders and VPN servers. File servers that store user folders, and email servers that store mailboxes should be placed in the intranet. |

The internal network also contains a Windows Server 2003 file server named Alecnet 1, which runs the DHCP Server service. The network contains 500 Windows XP Professional computers. The perimeter network contains a public Web server named Web CK1 . The internal network is connected to the perimeter network by a firewall. The perimeter network is connected to the Internet. You need to plan an IP address strategy. The IP address strategy must provide TCP/IP connectivity from the internal network to Web CK1 . Alecnet wants to reduce administrative overhead by automatically assigning IP addresses whenever possible. You need to choose the appropriate IP addressing distribution method for the computers on the networks. To answer, drag the appropriate IP addressing distribution method or methods to the correct computer or computers in the work area. Explanation: Static and dynamic routing both provide the same level of router performance. The drawbacks of static routing are the amount of manual maintenance the process requires and the routers' inability to compensate for changes in the network configuration. Dynamic routing enables routers to compensate for a failed router or WAN link, but it can generate a considerable amount of additional network traffic. Thus to comply with the requirements of providing TCP/IP connectivity from the internal network to Web CK1 and still reducing administrative overhead, the above configuration will be the solution. |
