      There are two purposes for such documents:
      Inform: part from the little "purpose" bit, the SANS does not do much.
      (2) A legal rope to hang a user with. What most of the SANS doc is.

      Folks, nobody reads a document like this. They will lose interest after the first few lines then either skip to the signing bit or throw it away.

      Real security comes from informing the user, not from baffling and swamping them with techno-legal bs.

      If you want real security, then clearly explain the issues.

        Provide VPN access, but limit them to only remote-desktopping into their current work desktop... then they are stuck with the restrictions, mappings, proxies, policies and resources they are usually allowed and have been signed off on. This is what we do to our "normal" vpn users. Also, Juniper Networks provides a nice sslvpn via web interface for those not able to handle a vpn client that this setup works wonders for...

            Yes, they use a java app which utilizes the SSL capabilties in the browser to create a tunnel. Usuallly they do like a lightweight remote desktop type thing, or you can spawn something that redirects IP. Lastly, they usally have a link to install a package for a standard IPSEC VPN client. Cisco offers this in their ASA (formerly PIX) firewalls, Sonicwall does also. It's helpful for users logging in from a non-company computer as there's not much config/support required. Obviously your LAN needs to be secure also, in case they log in at an airport kiosk and forget to log out or something. With RADIUS and some auditing, you're almost as safe as in the office.

          In three words: don't do it. The only "safe" way to allow remote access is if you issue company laptops to all of the affected employees.

          Assuming your corporate network is locked down pretty tight, the biggest thing you have to ensure is the security of the computer that the worker is using to access the VPN. The agreement and technology policy should either a) limit VPN access to company-issued computers (i.e., laptops) or b) require the use of firewall, anti-virus, hard-disk encryption and other security software from a list of approved products.

          Once you open the access to non-company-owned computers, you expand your scope of security, legal and system administrative risks dramatically. For example, what happens when some PHB downloads a report from your customer/sales database to their personal laptop while on vacation in Bermuda, and someone steals the laptop? Or if there's a keylogger on the computer that they use to log into the VPN?

          Unless your corporate security software licenses allow deployment of the software on non-company owned computers, you are going to incur a per-seat cost over $150 (possibly up to $500?) just to install required security software, or you will be forcing your workers to bear those costs. And then your network infrastructure team needs an on-going process to monitor those non-company computers to make sure that they are kept up to date with security updates for each of the installed products. At that point, it's more practical to issue company-owned laptops and integrate them into your standard support/licensing/update architecture.

          The current problems which are being, at least partially, blamed on deceptive lending practices in the mortgage industry would suggest that many people do not actually read through the legal documents they sign when they purchase a home. Do you think that for these deceptive loans, the stack of legal documents did not contain the truth? Of course it did. It was just buried in a pile of legalese, and people simply went with what the nice broker told them.

            And most of those people actually thought they could get away with it, that is legally stealing from the banks. I had similar offers made when I was looking for a home and I KNEW something was fishy about having loans that are cheaper than the deprecation of it's own value although I'm not a lawyer (if yearly inflation rates are higher than your APR something is wrong because then the bank would over time pay you to loan their money).

            Also I know that VARIABLE percentages means that the person loaning to you can jack up the prices as they want (just look at your energy bill with variable adjustments) but unlike an energy bill which you can change every year, you make the choice for the next 15-30 years no matter what happens to either yourself or the economy. It's a matter of federal law that rates and types are made clear to the buyer before lending and usually it's either on the first or last page, requiring a signature next to it.

            If people are too stupid and like to listen to their SALESman instead of forking over $200 to a real-estate lawyer (that's what it costed my parents 2 years ago) to review and make clear the paperwork to them then that's their own fault.

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.

      Here's a few things that are different and need to be considered when working from home. These are all things that I've been thinking about a lot for our company and, in my opinion, are very real issues for any company:

      1) Local shortcuts on your PC with saved passwords to work resources (eg, VPN connection details, saved passwords in web browser to access work webmail/intranets, etc)

      2) Log files for work-related chat - MSN, IRC, etc can sometimes contain confidential details.

      3) Work documents and other files.

      You can't just say you don't need a policy other than some vague notion of basic computer knowledge. Most people wouldn't think twice about downloading an important document and putting it on their computer at home.

      The two obvious risks that might lead to information leakage are a) their computer is compromised b) their computer is stolen. It's just a standard risk management excercise from here on it.

          For one thing you state that "you can get in from all but the most severely locked down internet kiosks". I guess you look at that as a feature, while I look at it as a malfunction. You've now extended your boundary and your risk to every poorly managed internet kiosk that any of your users use.

          Then, you claim "there's no risk to the corporate network". I don't know what sort of company you use, but if you think that providing a full desktop via Citrix, with access to all a user's regular internal documents and resources, to an endpoint that cannot be proved to be secure, is a "no risk" proposition then I would recommend you reconsider.

          Not saying that Citrix doesn't have a place--but the authentication/authorization needs to be two-factor (not just a re-usable username/password combo) and the authenticated user should ideally only have read access and then only to less sensitive files. If someone needs the ability to modify files, or to access particularly sensitive ones, then the Citrix client just can't be proved to be providing enough assurance that the underlying OS/hardware isn't compromised. And *that* is why I have three separate laptops from three separate organizations just to be able to get my job(s) done...

    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.

    The last few companies I've worked for make it mandatory for new employees to sign an AUP (Acceptable Use Policy). Sorta like a blanket coverage for all IT services, including networks usage. Depending on how large the company you're working for, you might be able to convince your HR to get all the existing employees to sign, too. That way you can avoid getting the employees to sign another document/agreement if you should implement new IT services.

    Before putting too much effort into this policy thing... Can I ask you one question: What's management going to do if someone breaks it? The majority of security policies only exist for two reasons -- to fire anyone who questions them and make management feel safe in having "done something to solve the problem". It's rather like expecting a terrorist to care that his car bomb is taking up two parking spaces... If this is management's only goal, just write some boiler-plate, broadly generalized piece that sounds really great but doesn't give any technical guidance. As a bonus, it'll never have to be updated after that, saving countless hours that would otherwise be spent securing the network.

    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.

    So what do your users do with VPN access? Access your network, yeah... then what? Email? Web access? You should already have AUPs for all of that, and access to those services via VPN is no different than if they're connected in the office.

    What you may be looking for is controlling the access, i.e. firewalls and virus scanners etc. If that's important, set up two-tier access:

    1. For users who have a laptop, put the access controls there, and make them only access the VPN via their company provided and controlled laptop. Then you set up the controls (firewall, virus scan, etc.) once and they apply whether they are directly connected or VPN'd in.

    2. For users who don't have a laptop, set up a remote desktop-type system where they use a web browser to access the remote desktop with SecurID.

    3. And I almost hate to mention this, but if most of your users are only accessing e-mail, think about setting up a Blackberry server. Sorry. Got my flame-retardant suit on. :)

    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.

  • Only corporate laptops get to connect to the VPN. Period. No exceptions.

    Laptops aren't much more expensive than desktops these days, so it's pretty easy to get a user that has a demonstrated need for remote access a laptop. That way I still have control and they get access to the network.

    Other than that, the standard AUP is extended to encompass the corporate PC, whether it's in the office or remoting in.

  • Unless, of course, you work for a porn company. Then porn away.

  • A formal agreement is just window dressing. You need to make sure you have controls in place to properly approve access, periodically review access to ensure appropriateness, and remove it in a timely fashion for terminated employees.

    All use of this computer is subject to monitoring, logging and review by (name of employer)'s IT department.
    No modifications of any kind may be made to (name of employer)'s computer by the employee.

    #1 Only computers provided by (name of employer) (with appropriate user restrictions, group policies, security software, etc...) are allowed to connect via VPN.

    #2 Only computers provided by (name of employer) may be connected to the network used for VPN access, at the time of VPN access.
      ie - home/personal computers must be disconnected before connecting the work computer - unless the work computer is on a completely separated / isolated network from the home / personal computers.

      What an incredibly totalitarian policy you propose. Someone does a web search to find directions to a restaurant on a work computer, and you can them? Glad I don't work from your company. In real life, a certain amount of personal use gets mixed in with the work use, and a successful company will judge its employees based on whether they get the job done.
      • And lets not forget that often remote access leads to some work time being mixed in with personal time. I would get a lot less done if I could't remote into work or clients in the evening to check on something which was being actioned in a different timezone.

    I don't have a formal policy, but I work with students on data that falls under privacy laws.

    What we tell them is:
    - Access from one computer only and that has to be specially secured
        -- Linux: Keep intsllation current, close all ports for incomming data, web-surfing only
              with current firefox or opera and limited to what is absolutely neccessary for their work.
        -- Windows: In addition a current anti-virus software. Discouraged.

    - We provide a computer for the VPN/SSH access for the thesis duration for the secured installation
        and even a second one for ordinary work, if they do not have one.

    - We warn them that loss of data would possibly be a criminal offense on their part (privacy laws)
        and that they need to be very careful.

    If you are really paranoid, gibve your users that second computer, or alternatively a CD-system created/modified by you for the remote access, and make using that mandatory. I think you will find that formal agreements carry little impact, as neglience is allways relative to the competence level of the person acting. Better to secure the access and not rely on legal stuff. If you require a specific installation for remote access, everybody not using it is doing something contrary to agreement regardless of competence level. You could even hardcode the VPN keys on a boot-CD (e.g. a modified Knoppix) to make it hard to circumvent this "remote Terminal" set-up.

    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.
