Remote Access Policies

Samalie writes "My company is considering implementing a formal remote access policy (and agreement for staff to sign) for users who access our network from home via VPN. Does anyone out there have any suggestions as to what this policy/agreement should contain? Anyone have their own corporate policy that I can borrow from? This is the first time I've come across anyone wanting a formal policy for this & online searches haven't been very helpful."

    You could make a VPN boot disk.
    This way you can separate what is on their machine with the VPN instance. Requires no brain power to use. Boot's up, big VPN icon. Click enter password, good to go.
    Obviously, encrypt it.

  3. One policy: don't make it necessary by davidwr · · Score: 4, Interesting

    Either give people laptops or give them a way to do what they need to do on servers you control.

    This can be a web-based front-end to the applications they use, an ftp site so they can up/download files and edit them on their home computer, or even something like Windows Terminal Services or Citrix.

    If your company is enlightened enough to not use Microsoft, there are even more options available.

    If you allow people to remote login, you need to make very sure that not only is the VPN tunnel secure against attacks, but that their machine can't do anything hostile to your LAN in case their password is compromised. Of course, you should be doing that anyways but many companies don't treat computers in the network as "presumed hostile" to every other device on the network. You should always do that, but If you are going to allow remote login it's even more important.

    As a bonus, if you put most of your business-critical applications on a server you control, it's easier to make sure data gets backed up and you can usually get away with a longer computer-replacement cycle or buy slightly cheaper computers when you do replace them. Of course, you'll pay more for server costs and you'll need more expertise in your IT dept. to manage it, but in many shops this is worth it.

      Smartcards and native connection stuff in Windows. Once connected you were "quarantined" until a security scan had been run on your machine, and even then you had different access based on location.

  5. Don't use 'user' policies - use 'system' policies by vawarayer · · Score: 5, Interesting

    I find that whatever the user signs, it always gets broken one time or another. That is why I use - whenever possible - system policies instead of making them sign anything. If they can't do what you don't want them to do, it ought to be more reliable.

    • Set up firewall rules that would let them connect only to your mail server, or whatever they need remotely.
    • Make them connect to a terminal server with a very restrictive set of privileges and access to the network.
    • Close unnecessary remote ports so they can't do stuff you wouldn't expect, or infect your network with worms.
    • LOG ! LOG ! LOG ! I find everything should be logged! Especially traffic going in/out the local network. Have a good log retention policy.
    • ENFORCE strong passwords and change 'em when you feel fit.
    • This list could go on...

    The main idea is: restrict their remote access to what they really need. Some purist will reply 'oh yeah, but even if you do that, there's a way around for such and such reason.' or that it will become too restrictive. My answer: adapt to your user needs without letting it be the Wild Wild West.

    Maybe both signing an agreement AND enforcing policies is the best way to go.

  6. What are the requirements? by Fastolfe · · Score: 4, Interesting

    Did an executive really just say, "I think we should have a formal policy"? Don't create bureaucracy and policy just for the sake of having bureaucracy and policy (making management look busy). Build your policy on the demands of your organization, and formalize it when it's necessary to do so.

    That being said, if your business doesn't deal much with sensitive data, you could get by with allowing personal computers, with up-to-date anti-virus software (maybe the company can pay for AV software for home computers). If you do deal with sensitive data, I would recommend issuing laptops to employees that need to work from home, and only allow VPN from those systems. Use certificates.

    Please don't use the SANS policy. As someone who performs risk assessments for a large company I am tired of vendors sending me SANS policies to review. They are old and outdated...some of them contain typos and it really tells me as an auditor that you really don't take security seriously because you can't take the time to tailor a document to your business needs.

    They are generic reference documents to use as a guide not as a final product. Even the guy who wrote the Remote Access policy for SANS thinks it's a joke.

    I took a different approach, we use Citrix for remote access. We have the Java client installed and have a link to the zero touch client which doesn't need to be installed to run. That way you can get in from all but the most severely locked down internet kiosks. There's no risk to the corporate network and it enables my user to be productive from anywhere. It's also WAY faster than a VPN for most types of work.

    My company is so paranoid about unauthorized file transfers that they have discontinued VPN and only allow Citrix. The Citrix configuration is setup so that it will not permit saving to the local computer's hard drive. On one hand, it lessens some risks that could occur if your personal computer was connected by VPN. On the other hand, it makes for a lot of email traffic as people send themselves files so they can work on them outside of Citrix.

    #1 Keep the VPN use work related. Follow the same network policies as if in the workplace.

    #2 Scan the home PC on a regular basis for malware. Last thing the company needs is trade secrets, password and login info, and email stolen by some hacker who happened to get a key logger trojan on the Home PC, and then sell them to the higher bidder or steal corporate bank and credit card accounts. That means keeping your Antivirus programs updated every day and scan for viruses at least three times a week.

    #3 You are on the honor system, Work can only monitor your activities on the VPN network, but not your Home PC and the Internet being used by your home PC. Yes it is alright to check your local email on your home computer, but use common sense and don't spend a lot of time doing personal things on your home computer and home Internet connection. We'll notice it when the VPN activity stops for more than 15 minutes, and your work productivity drops on the VPN. Yes you can take two 15 minute breaks and lunch hour or half hour, but we'll really notice it when you do nothing on the VPN for hours. Either you are goofing off and doing personal things, or the connection is dead, but we can tell by pinging your home computer to test if the connection is dead and deduce your wasting time.

    #4 Keep all company email professional. Make effective use of company email and web sites and software. Don't use them and act like you do when you are posting Anonymous trolls on the Internet or your Myspace page.

    #5 Do not access other user's accounts unless you are given permission by management for troubleshooting something or testing out software. We know that your profile might not have the same issues as a coworker, but only IT staff should be loging in as other employee's accounts only for testing purposes. Do not use an alias either on the VPN or create a fake account via a hack, but use the account and account name assigned to you.

    #6 Do not save work data on your personal hard drive, instead store it on a server drive.

    #7 Do not run cracking and/or hacking tools on the VPN, do not do any denial of service attacks over the VPN.

Files only traverse through a user browsing back to the local pc and all files are scanned. We also use the old file explorer view so we don't have exposure to folder content browsing bugs which are the only attack vector I am aware of through the callback mechanism. This is certainly a MUCH smaller attack surface than a full vpn connection where to be functional all sorts of ports need to be open.

    I'm not arguing with this; you're right on. I was simply disputing the notion put forth by the post I was responding to. geekmux said that if these legal agreements had teeth, people would read them and offered as an example the notion that people generally read the paperwork that they have to sign when they purchase a home. I maintain that the current financial mess is due, in part, to the fact that people don't read legalese even when not doing so can have dire consequences. So giving these agreements more teeth would be of little help in getting people to read and adhere to them :-/
