What is Safe-Connect and why is it being used?

  1. Safe-Connect is a network access control technology the college is using so it can provide wireless network services that comply with Troy University policy: specific network behavior must be attributable with an individual,
  2. devices on the network must be configured to prevent abuse.

Safe-Connect will allow the campus to comply with the first requirement by requiring users to authenticate with a username and password before allowing them to use wireless network services. When you authenticate, the system records which network address you were assigned and how long you used it. That combination of data allows the campus to associate questionable network behavior with a specific user account and the person to whom that account was issued. Your username and password are your keys to the network, don't share them with anyone. You are responsible for all acts performed using your account. If you are concerned that someone may be able to use your account change your password immediately.

Safe-Connect can currently only enforce the configuration requirement on systems running the Microsoft Windows operating system. Client applications are being created for other operating systems. When those clients are available the campus will require their use too.

Please refer to the frequently asked questions page for answers to some specific questions. If you have remaining questions after reviewing the information provided, please use the Student technical help web form to send your question to the technical support staff.

What do I need to do?

First and foremost, you must know your Troy University Email username and password. Your password should be kept secret. Do not ever write it down or share it with anyone.

Secondly, only if your device is running a Microsoft Windows operating system you will also need to:

  • know if your computer has a personal firewall turned on and add PolicyKey.exe to the exception list
  • turn on the Microsoft Windows automatic update service,
  • have an updated anti-virus application,
  • have the Safe-Connect client application installed and running.

How do I turn on Microsoft Windows Automatic Update?

  1. Open the Security Center control panel (Start --> Control Panels --> Security Center)
  2. Click "Automatic Updates"
  3. Ensure "Automatic" is selected
  4. Click the OK button to save the settings

Which anti-virus programs will Safe-Connect recognize?

As of March 2008, Safe-Connect is able to recognize and verify the following anti-virus applications are installed, updated, and operating. Other anti-virus programs are added routinely.

It is critical that you have only one antivirus program installed on your computer. Having multiple anti-virus programs installed will result in false readings and prevent you from using the network services.

AVG Kaspersky Sophos
Avast AV McAfee SpySweeper AV
Authentium McAfee NA Symantec
AVGuard McAfee 45 Symantec Corporate
BitDefender Panda TrendMicro
EZ Antivirus NOD32 TrendMicro Corporate
ZoneAlarm AV    

There are many antivirus products available. Some are free and some require subscription fees for continued protection. Many computers come with trial versions of subscription based anti-virus products. If your trial period ends and you do not subscribe and pay the subscription fee you will not receive future updates, your computer will not be protected, and Safe-Connect will not allow your computer to connect to the network.

How do I get and install the Safe-Connect client?

  1. Read all of these instructions first.
  2. Click the link below to download the application.
  3. When prompted to either run or save the file, click the "Run" button.
  4. Ignore the warning that the publisher could not be verified and click the "Run" button.
  5. After the installer downloads it will run.
  6. Follow the prompts presented by the installer to proceed through the installation process. You can expect to click an "Install" button to start the installation process and a "Finish" button when the installation has completed successfully.
  7. The PolicyKey application will be running as a background process and will start automatically each time you start up your computer.

I have downloaded and installed the Policy Key, but when I try to go online, NAC gives me a message that I need to install the Policy Key.

  1. Something is preventing the Policy Key from communicating with the Safe Connect server. The most common cause is a firewall or antivirus program denying access. You'll need to make an exception from your firewall configuration to allow internet access for SCClient.exe and SCManager.sys. Another reason may be that the Service is "Hung". In order to rule this out, Click on the Start Icon and select Run then type "services.msc" and click OK. When the Services window opens, look for Safe Connect Manager and click on it. Then in the upper left corner of that same window, click on the "Restart" option. Now check to see if the Safe Connect Manager has changed from "Stopping" to "Started". If this does not work, go to the Control Panel, open Add/Remove Programs or Programs and Features...depending on your operating system. Find the Safe Connect software and select Uninstall. Reboot your computer, then re-install the software from the web page that comes up asking you to re-install the Policy Key Software.
  2. What is probably happening is that your firewall is blocking the Policy Key from communicating with the NAC. What you need to do is add the Policy Key as an exception. To do this, open Security Center and click on "manage firewall". In the new window that comes up, there will be an exceptions tab. Click that tab, and then click the "Add" button. Navigate to the Policy Key and click "OK".

I have anti-virus installed and up to date, but NAC still gives me a message either telling me to update it, or that it is not installed at all.

Most likely, you either have two anti-virus programs running together or an old anti-virus program wasn't uninstalled completely. Two anti-virus programs running concurrently will sometimes confuse NAC into giving a false report of no anti-virus program being present. For this reason, we recommend you use only one anti-virus program and uninstall the other. Also, left over folders, etc, from incompletely removed anti-virus programs can have a similar effect on NAC. If you formerly were using a different anti-virus application, you can try uninstalling again, using the old installer. If this doesn't work, you can contact our Help Desk at 670-4257 (HELP) or ext 5660 for help removing the program.

What am I allowed to access when quarantined?

The Troy University support website http://it.troy.edu and other places you need to fix your computer and get out of quarantine, like Anti-Virus Software and Internet sites off campus such as Microsoft Windows Update Services, along with other on-campus remediation resources you may need. These might include school-provided versions of anti-virus or anti-spyware products, etc.

Can I download operating system software security updates while quarantined by Impulse?

Yes. Any Windows Updates your system needs can be downloaded and installed while you are in quarantine mode. The same applies to virus definitions from most of the major anti-virus providers and to anti-spyware updates from Microsoft, SpyBot and Ad-Aware.

When I run Windows Update Services, I get a message stating that the product key used to install windows is invalid. Why?

Windows Update will fail if your Windows Operating System is not properly licensed. You must have a legal copy of the operating system to connect to the university network. Please contact Microsoft or your PC manufacturer with questions.

Do I have to use the Impulse Policy Key?

Yes. All Microsoft Windows PCs and Macintosh computers are required to use the Impulse Policy Key to ensure a safe computing environment for all and it is required for network access.

What happens if I do not wait for the Evaluation Page, or open another browser window before the 30 second Evaluation Page has completed?

If you continuously see the http://trojan.troy.edu/hub/ page, you did not let the Evaluation properly finish. You should close the browser and re-open it and that should fix the issue, If not, may need to logout using the Logoff button located at the top right of the page on http://trojan.troy.edu/hub/. Then Log back in and wait until the screen clears the 30 second Evaluation page and sends you to the Intranet page. At that point, you will able to browse without any issues.

Why can I not get away from the Internet Page?

Typically, Internet Explorer is not releasing cached web pages properly. In order to change this, open Internet Explorer and follow the steps below:

IE 6:

  1. Go to the top and select "Tools".
  2. Select "Internet Options".
  3. On the "General" tab, in the middle section where it specifies "Temporary Internet Files", click on "Settings".
  4. Click on "Every visit to the page".
  5. Change the amount of disk space used to 10.
  6. Click "OK".
  7. Click "OK" again.
  8. Close then re-open browser.

IE 7:

  1. If Menu Bar is not showing, look in the upper right corner for "Tools" and select "Menu Bar".
  2. Once the Menu Bar is visible, follow the same steps for IE 6 to make the appropriate changes.

What happens if I uninstall the Impulse Policy Key?

You can uninstall Impulse Policy Key at any time; however within minutes you will then be unable to access the Internet through a campus network running NAC. You will be required to reinstall the Policy Key as if you are a new user to gain Internet access.

How do I know the Impulse Policy Key is running?

On Windows machines with Windows 2000 or Windows XP, you can right-click any blank space on the task bar at the bottom of your screen and select the option "Task Manager". When the Windows Task Manager appears, click the "Processes" tab and look for the process "SCClient.exe". Mac OS users can open the Activity Monitor located in the Utilities folder. From the Activity Monitor look for the process Policy Key

Is the Impulse Policy Key compatible with my system?

The Impulse Policy Key is compatible with and required for Windows Systems. At the present time, Linux, and FreeBSD machines are not required to install the Policy Key.

What does the impulse Policy Key actually do?

The Impulse Policy Key continuously validates that your system has the minimum security software running and up-to-date as per the school's acceptable use policy.

What are these selected applications?

Once the Impulse Policy Key is enabled, we will require that your Windows Automatic Updater is running. You must also have running anti-virus software installed with the most current definitions available. It is a suggestion, but not a requirement to have anti-spyware installed and running.

What are the benefits?

The Impulse Policy Key is part of IT's effort to help you keep your computers as free as possible from viruses, spyware, and operating system security holes. Machines protected in this way generally perform much better and require much less downtime due to damage caused by malicious software. Also, the Impulse Policy Key can help to ensure that the average user has the fastest possible browsing experience while connected to the University's network. It does this by ensuring that communication from malicious software does not flood the University's internet connection, resulting in much slower connections for legitimate users or by restricting certain applications that would otherwise consume an unfairly large share of the School's bandwidth, again resulting in a slower connection for the majority of users.

What if my system is not up-to-date?

If your system has been determined not to be up-to-date, your computer will be "quarantined." While quarantined, you will still have access to academic resources such as online learning tools and online registration, as well as to update servers for your operating system, anti-spyware and anti-virus software.

What about my privacy?

Your privacy is important to us. The Impulse Policy Key scans only for Windows update services compliance, anti-virus and anti-spyware status. No user data is collected or stored.

How do I Log Out if I'm in a Lab or in the Library?

If there is not a logout icon on the desktop, point the browser to http://trojan.troy.edu/hub/ and look in the upper right hand corner and there will be a Logout Button you can click on.

I've been asked to login more than once. Why?

Though the system is configured for a one time login, you may be asked to re-authenticate periodically. The most common reason for this is if your computer has been off the network for some time and lost its IP address lease.
