You had been taking a short vacation, and when you come into work on Monday morning, Orange is already at your door, waiting to talk to you.
"We're got a problem," Orange says, "It seems that the password used by our Vice President of Engineering has been compromised. Over the weekend, we found this account had logged into the network 25 times. The Vice President was not even in the office over the weekend."
"Did we get the source of the compromise yet?"
"No, but it won't surprise me if it is our new neighbors at MassiveCorp. I need to you to come up with a realistic plan and bring it to me tomorrow afternoon. This problem must be resolved, and like everything else we do not have unlimited funds so keep that in mind."
Based on this information, choose the best solution to the password local authentication problem in the Executive building.}

By now, you are feeling confident that the security of the MegaCorp network is getting under control. You are aware that there are still several critical areas that you must deal with, and today you are addressing one of those areas. You have been able to take care of the router, firewall, security policy, and intrusion detection, now you are concerned with some of the hosts in the network.
Since the organization is not very large, you are the only person working in the IT end of the company. It will be up to you to directly work on the systems throughout the network. You make a quick chart of the systems you know should be in the MegaCorp network: Server0001, 10.10.20.101, Windows 2000 Server
Server0010, 10.10.20.102, Windows 2000 Server
Server0011, 10.10.20.103, Windows 2000 Server
Server0100, 10.10.20.104, Linux (Red Hat 8.0)
User systems, 10.10.100.100~10.10.100.200, Windows 2000 Professional
The addressing that you recommended months ago is in place, and it follows a distinct logical pattern, you are hoping that no new systems are hidden in the network somewhere.
In the company, you have been granted domain administrator rights, and no other user is authorized to have administrator, root, supervisor, or otherwise privileged level of access. All the Windows systems are to belong to one windows domain called SCNA.edu. Users are no longer allowed to install unauthorized applications, and are all to use the file servers for storage. Although they have the ability to do so, users are not supposed to store any work data on their local systems.
The servers are located in a server cabinet that is inside your office, so you decide to start working there. Using your knowledge of MegaCorp select the best solution for hardening the MegaCorp operating systems:}

Now that the network is moving towards a trusted network, you are preparing for the specific new implementations in GlobalCorp. Just as you wrap up some paperwork for the morning, Blue calls you and lets you know that you are going to be needed in a meeting this afternoon.
You get to Blue office and sit down at the desk. Blue begins the conversation, "You know we have some solid fundamental issues addressed in our new trusted network, but I have yet to feel that we have addressed any serious concerns."
"I're been thinking about some similar issues," you reply.
"Good, then I sure you have been thinking about our email. Right now, I cannot guarantee the integrity of any email, and I cannot guarantee the confidentiality of any email. We have reasonable controls towards guaranteeing the availability of our email, but what the point if there is no confidentiality or integrity?
"I agree. I think that addressing this issue should be an immediate priority."
"One concern is that whatever the system is that we put in place, it must be very user-friendly. As we roll out these new systems, anything that will significantly increase the calls into the help desk is something we need to minimize. A second concern is that it not be too costly. We already have this new investment in the trusted network, we need to be sure that we utilize what are building to the fullest extent possible."
"I think we should be able to do that without much difficulty. I already have some solid ideas," you reply.
"OK, take a few days on this. For the moment, just concern yourself with the executive building; the others can follow the plan in their own buildings. Let meet again this coming Monday and you can describe your suggestion then."
Based on this conversation, and your knowledge of GlobalCorp, select the best solution to the email problems in the network.}

For three years you have worked with MegaCorp doing occasional network and security consulting. MegaCorp is a small business that provides real estate listings and data to realtors in several of the surrounding states. The company is open for business Monday through Friday from 9 am to 6 pm, closed all evenings and weekends. Your work there has largely consisted of advice and planning, and you have been frequently disappointed by the lack of execution and follow through from the full time staff.
On Tuesday, you received a call from MegaCorp's HR director, "Hello, I'd like to inform you that Purple (the full time senior network administrator) is no longer with us, and we would like to know if you are interested in working with us full time."
You currently have no other main clients, so you reply, "Sure, when do you need me to get going?"
"Today," comes the fast and direct response. Too fast, you think. "
What is the urgency, why can this wait until tomorrow?"
"Red was let go, and he was not happy about it. We are worried that he might have done something to our network on the way out."
"OK, let me get some things ready, and Il be over there shortly."
You knew this would be messy when you came in, but you did have some advantage in that you already knew the network. You had recommended many changes in the past, none of which would be implemented by Purple. While pulling together your laptop and other tools, you grab your notes which have an overview of the network:
MegaCorp network notes: Single Internet access point, T1, connected to MegaCorp Cisco router. Router has E1 to a private web and ftp server and E0 to the LAN switch. LAN switch has four servers, four printers, and 100 client machines. All the machines are running Windows 2000. Currently, they are having their primary web site and email hosted by an ISP in Illinois.
When you get to MegaCorp, the HR Director and the CEO, both of whom you already know, greet you. The CEO informs you that Purple was let go due to difficult personality conflicts, among other reasons, and the termination was not cordial. You are to sign the proper employment papers, and get right on the job. You are given the rest of the day to get setup and running, but the company is quite concerned about the security of their network. Rightly so, you think, if these guys had implemented even half of my recommendations this would sure be easier.You get your equipment setup in your new oversized office space, and get started. For the time you are working here, your IP Address is 10.10.50.23 with a mask of \16.
One of your first tasks is to examine the router configuration. You console into the router, issue a show running-config command, and get the following output:
MegaOne#show running-config
Building configuration
Current configuration:
!

end
After analysis of the network, you recommend that the router have a new configuration. Your goal is to make the router become part of your layered defense, and to be a system configured to help secure the network.
You talk to the CEO to get an idea of what the goals of the router should be in the new configuration. All your conversations are to go through the CEO; this is whom you also are to report to.
"OK, I suggest that the employees be strictly restricted to only the services that they must access on the Internet." You begin.
"I can understand that, but we have always had an open policy. I like the employees to feel comfortable, and not feel like we are watching over them all the time. Please leave the connection open so they can get to whatever they need to get to. We can always reevaluate this in an ongoing basis."
"OK, if you insist, but for the record I am opposed to that policy."
"Noted," responds the CEO, somewhat bluntly.
"All right, let see, the private web and ftp server have to be accessed by the Internet, restricted to the accounts on the server. We will continue to use the Illinois ISP to host our main web site and to host our email. What else, is there anything else that needs to be accessed from the Internet?"
"No, I think that's it. We have a pretty simple network, we do everything in house."
"All right, we need to get a plan in place as well right away for a security policy. Can we set something up for tomorrow?" you ask.
"Let me see, Il get back to you later." With that the CEO leaves and you get to work.
Based on the information you have from MegaCorp; knowing that the router must be an integral part of the security of the organization, select the best solution to the organization's router problem:}
