lanimreT asks: "Notebooks are a large problem for IT managers. They carry viruses and other malware back into the network and are less reliable than desktop PCs for more than one reason. Yet, every employee MUST have one for his job. How have other IT managers dealt with the various problems that notebooks create?"

    Put your laptops on a DMZ-like subnet. Don't allow unrestricted access from that to the rest of the LAN. ie.: only allow them access to your servers and other necessary resources. If they don't need to access Bertha's PC in Accounts Receivables then block it.

    Block spyware sites on your firewall and log it. If you see a laptop trying to get to $SPYWARESITE you know they've installed crap. Go remove it.

    Make sure they have antivirus and antispyware stuff installed, up to date and running. A lot of people turn it off because "it slows my machine down"

    Ideally you won't let them have admin access. Far too often laptops show up with Kazaa or other shit installed because they let their kids play with the machines at home. Bad move, it's company property with company information but many people think the other way around. Assuming you're the IT manager you should have every right to remove such crap. Check your policies first.

    Very important: Make a log of everything you have to fix If and when you start to enforce policy you need hard data to back up your actions.

    • DMZ-like subnets are a great idea but really, if you lock down the laptop before giving it to the employee and insure that they can't install crap or otherwise modify and crap on your rock_solid configuration through local/group/security policys, then you have one less thing to worry about. I haven't really had more of a problem with laptops than I have had with PCs.
      • I like the DMZ method as another layer of security. A laptop that has been on the road for a while may not have had updates installed. So the person hooks it up when they get back home from a trip and whammo the latest Windows worm gets them.
        • The latest? Try one from months ago...I ended up removing SASSER from my brother's business laptop not too long ago. It seems he hadn't used that particular one online for several months, and didn't see anything wrong with hooking it up to the Internet without patching it. It lasted about fifteen minutes.

        The laptops at work come locked down and you can't do anything until a tech
        visits. Rather than wait for days until a tech comes, some people wipe the
        drive and reinstall windows, thus negating any benefit of locking the machine
        down in the first place.

        The moral of the story is if you have access to the hardware, then the machine
        isn't really locked down.

          At that point, if you want to install any work related software, you need to be a member of the domain/active directory. If not, you don't get connected, either while in the office or via VPN.

      • It would definitely reduce the functionality of the laptop away from networks, but wouldn't necessarily make them useless. "Windows Server 2003" appears to support a redirected local drive which appears as a "share" on the terminal session. Users who are going to be away from a network but NEED to work on something can use that to copy the file to the local drive before they disconnect, and then re-upload when they reconnect later.

        That would slightly compromise the "nothing stays on the local system" but

    • Or, why not leave the laptops wide open, but filter all traffic from them on your corporate network except for the port for Terminal Services. The managers would complain about synchronization issues, no doubt, but c'est la vie.

      Other than that we just have to keep AV/AS stuff running and up to date, and have scary policies regarding installation of non-approved applications to hopefully cut that down.

      But please put Winamp on that list. Let's be realistic too, okay?

      By installing the bare minimum (maybe even linux running from compact flash) and locking it down so they are only allowed to connect to a terminal server certainly has it's advantages.

      They would need to be able to connect through ... LAN, dialup, broadband, wireless (office, motel, airport, web cafe etc), mobile data, directly or via a VPN. Of course, those tools would need to be installed and have a nicely locked down configuration that they can't f$#% with.

    Posting as AC to protect my job, however our method is quite extensive, and the high-level details are worth sharing for others to learn from.

    My company's (a large online e-tailer and book seller) approach involves several methods to protect remote machines and limit access.

    For remote access, a customized platform agnostic VPN device (running an embedded linux) piggy-back's onto the laptop. The device is powered by the laptop's USB port, and acts as a firewall in addition to a VPN gateway. The device can connect to the internet either via it's built-in compact-flash wireless card (supports WEP or open wireless) or an ethernet connection. When the tunnel is down, the laptop is still well protected by said firewall. When the tunnel is up, all traffic is routed through the VPN tunnel, and subject to corporate firewall rules. The VPN device is tied to the laptop's MAC address, and will not work with any other machine unless reprovisioned by an admin with appropriate rights. The user must authenticate on the device (which updates credentials each time it connects) before access is granted internally, and only the provisioned user has access to login to the device. Three failed login attempts will delete the data on the device, rendering it useless to any theif, and requiring it to be reimaged by corporate IT. The only means of accessing corporate data from "the outside" is via this device or a direct dial-up. There is zero access to internal systems without either of these methods (not even webmail). Dial-up numbers cannot be modified by the user which prevents them from connecting to any random ISP.

    I don't know if either connection is dropped into a DMZ for further protection, however the local VPN device does packet filter certain types of packets on the way out for extra measure.

    On the software side, the machines (when running Windows of some sort) run an antivirus and policy enforcement suite which is maintained by a corporate server. Policies enforce encrpytion of the user's mydocs directory should the laptop be otherwise compromised. Policies also restrict the user from installing software that isn't deployed via SMS. Additionally, anti-spyware software is installed on the machine to allow IT to remove threats. Because users must connect to the corporate network to do most job functions, these tools remain fairly up-to-date.

    To protect the laptop, user passwords are changed regularly and a strong password requirement is enforced in addition to a fairly long password history retention to prevent reuse. Usernames are not retained in the login screen. Laptop screens are forced to lock after a short amount of time to prevent unattended access.

    For browsing, users are permitted either IE or Firefox, however most users prefer the latter :-) Email can be accessed via web, Outlook/Evolution (ick) or Thunderbird via IMAP.

    I'm not sure on the size of your company, but if your budget allows, this seems to be highly secure and admitedly, well thought out means of enforcing security and protecting networks.

  • Lock the sons of a bitches down hard. Don't allow the laptop user to install software. Don't allow them to run as an administrator account. Use policies to allow them to perform any administrative tasks that they might need, such as being able to change their IP address. Use a corporate-controlled firewall, preferably using a firewall that allows you to set a global policy and force it enabled. This is a host-based firewall, besides the actual corporate one to the Internet. Turn off all unecessary ser

    Require absolute standardization. Create a custom installation image similiar to the standard desktop installation including all utilities and software licenses required for the job. Do not give the users administrator rights to anything. Require them to hook the laptop up to the network every week or so to receive updates, patches, and submit to a system scan for unauthorized software and files.

    If the system is determined to not meet company standards, give the employee a day to remove personal and work files, and then take the computer back to your IT cave, scrub the hard drive, and re-install the standard image from scratch before giving it back to the employee.

    If the company has purchased the laptop, it must be very very clear that the laptop, and everything on it, belongs to the company, period. Policies like this will help keep "innocent" employees from accidentally bringing back something hazardous to the company network, and any employee savvy enough to work around the restrictions should also have the skillz to avoid undetected malware.

    And if you have trouble employees who keep getting caught with unauthorized files, software, or who keep bringing back malware infested machines, your security policy and the measures required to circumvent the policies ought to be enough ammunition to support firing them for cause. Or at least confiscating their computer, locking their account, and demoting them to a job that doesn't require the use of a computer. Like janitor or something.

    Make it very clear that as their job depends on them having access to a computer, and their access to a computer absolutely depends on them taking care of it and following company policy, if they do something to cause their network and computer privledges to be revoked then they will either be moved to a less technical job or released.

    My company works in a very similiar fashion, except that we have the threat of jail time thrown in just for flavor. Guess what... Nobody f**ks with the IT guys and the very very few who violate policy and get caught become well publicized examples of how to ruin you life. Is installing that intardnet solitare game, or peeking at the porn site worth your job? How about worth half your salary for 3 months and a month in jail before you get fired? Well, most companies don't need to go that far, but the general idea that messing with the IT resources is dangerous to company survival is something that nobody will seriously consider unless the both the policies AND actions taken to enforce those policies are black and white. No questions askes, fail to bring in your laptop for a weekly update/scan and you lose compter network privledges until you comply. Fail to comply 3 times or get caught violating the rules 3 times, and lose privledges until reinstated by the appropriate company VP, board member, co-owner, whatever.

    If you let people take advantage of the IT department, EVERYONE will bypass the rules. Sure, most slashdot readers could do that without causing harm and many could do it without any real risk of getting caught, but chances are that some of the policy breakers will be relatively incompetent and one single person can bring down the entire company, if the security compliance policies are not clearly defined and rigorously enforced, with real penalties for violations and repeat violators.

    I've been on both ends of the corporate IT stick... Been beaten for sidestepping policy, and done the beating later on when it was my turn to enforce policy. There can't be any question in anyone's mind that the policies simply can't be broken without consequences, no exceptions.

    Go ahead and do it differently, if you don't mind seeing your company on "CNN Money" next week as being the latest gropu who just let some intruder walk away with your customer database or all your company's proprietary info. Yea, that happened to my company too, with some stuff that had been outsouced.

      Great in theory, lousy in practice. For what it's worth, I worked for years as a part of the desktop management team for a Fortune 500 company. I switched jobs about a year ago. On my corporate-issued laptop, I have the full suite of applications 'certified' to work on the reference build of XP.

      I just checked and found that as a part of DOING MY JOB, I need 50 - count them - 50 utilities that are not provided, certified, or approved to go on my laptop. I'm not a developer, but I am a tech lead for implementation of a COTS product deployed on a J2EE app server. Those 50 utilities include:
      Cygwin, jEdit, filezilla, ultravnc, SP2 & a RAM defragger (b/c my laptop won't hibernate without it) ldap tools, putty, gaim, pdf utilities, an HTML editor, and many others. Pretty much none of these would be 'corporate approved' and without them, my job would be MUCH harder.

      I can edit config files in notepad, which *is* corporate certified. It it the most efficient tool? No way! Editing in jEdit is much richer and faster - syntax highlighting for perl, xml, shell scripts, batch files, etc.

      This also does not address the issue with the fact that without local admin I'd be unable to install print drivers for my network-attached printer at home. I also would be unable to connect to my wireless LAN at home, because I would not be able to configure the WEP settings. Do I do real work at home? Yup.

      Here's my point: I'm not using my laptop as a personal computer. My kids never touch dad's work laptop, and my personal software is installed on my personal PCs. Without local admin, my job would be MUCH harder. Is it expensive for our company to let me have a unique config? Probably. How expensive would it be to not let me have the tools I need to do my job?

      What makes sense? In my view, you're penny wise and pound foolish to prevent me from installing the tools I need.

      • This is the real problem, in my opinion. I've never worked at a company where they had both the will and the ability to totally lock down the machines, AND the will and ability to be quickly responsive to installation and authorization requests. This gets especially bad when IT people get to make policy instead of being responsible for implementing it.

        It can take *6 months* to get approval to install a no-cost, industry standard application (Eclipse, for example). Too many IT departments get into this us

    • I would suggest to the poster that ONLY company issued machines be allowed to ever connect to the company systems, in or outside the perimeter. The "locked down" bare bones configuration are standard practice with better defense contractors and large financial companies, especially brokerage firms...I know this from experience. SecurId two part logins through VPN that basically only let you access your desk top system and only as your employee identity tend limit unauthorized access. And be very careful
    • Wrong.

      Good luck getting this kind of policy enforced with the sales drones. They are an entirely different breed, and I guarantee that if a sales guy can't get to texanholdmpokr.com, it will be your fault.

      He just has to say, "I cant get to the internet and make my deals/leads", and your policy will become the problem. The boss hears, "IT is keeping me from doing my job".

      This problem goes much deeper than some simple policy changes.

  • I work for a gov. agency that has a lot of laptop users. We also use Exchange/Outlook and have limited mailbox sizes to 150MB. The biggest problem that we have is that users want to store their Archive PST files on their laptop and then scream at us when their HD dies and they lose their old emails. It's a no win situation for us.. Management won't authorize more Exchange server space; if we force them to store their PST on a file server, they complain; if they lose a PST on a bad laptop HD they complain.

    • i have a perl script that i wrote that copies psts to network storage, is hacky, but it works
    • The problem with that is that PSTs can be big and it might take awhile to do the copy. I have to ensure it won't run when the user is on dialup or VPN.

      This will just require you checking to see what subnet the laptop is currently on before copying. That's what my current systems do - it won't copy the files unless you are in the "office network" environment, based on the subnet.
    • Look into BackupPC. It's pretty god for backing up laptops.

      Any suggestions!?!?!?

    • Couldn't you use roaming profiles?

      Then put the .pst in the user's homedir, and set outlook to use it.
    • The solution would be simple if users weren't so addicted to Outlook.

      I replaced Exchange with Postfix and Courier IMAP, and I'm a happy mail admin since.

      For the client side, I always hated Outlook, so I installed Thunderbird on all machines.

      Unfortunately, out of a dozen users, only one seems to prefer Thunderbird. The others insist on using Outlook 2003, despite all the problems they regularly have with it. For example, Outlook doesn't start, complaining that the server is not accessible or something. They
  • I have never had a laptop at the IT places I worked.
  • First, if you want control of the laptops, be sure to set a bios password and disable booting from devices other than the hard disk. This will keep most people from installing their own operating system.

    Second, if a machine gets really fucked up, you'll want to be able to fix it quickly. I suggest using disk images. You'll need to partition the disk drive so that you can re-image without wiping out the user's files. Remember that with NTFS, you can mount a partition in any empty folder. You know what to do
  • ...lack of physical security means lack of assurance of any security.

    If you don't control the laptops, don't trust them to behave. Design your network and servers -- the things you can control -- with the idea that they can be 'attacked' from anywhere; Internet or intranet.

  • Notebooks logon via a seperate server, they have their own IP address range whenever on the network and their own DHCP server. The link between the notebook servers and the rest of the network is firewalled.

  • All these pathetic posts about locking down the (l)users make me want to hurl. You are trying to use technical means to solve a social problem, and IT WILL NOT WORK. And by the way, who the hell are you, to tell me what I do or don't need to use my computer for. Get over yourselves, you BOFH wannabes.

    Your job is to provide me with the IT tools I need to do my job. Have all the policies you want, but the second those policies keep me from doing my job, they have to give way.

    How about this? You give me adm
    • I'd have to agree partially- Yes - users need/must have the right mix of software and hardware to do their jobs. Their computer is a business tool. One privledge model for an entire organization doesn't work. Systems need to be locked down - for security reasons- an default install with admin prives reading email, accessing the web is asking for trouble. Protect the users from them selfs. Users are NOT sysadmins- users are paid to do their job, admins are paid to do their job. Users responsibility is to
  • Bolt the laptops to the desks.
  • I work in my jobs IT Dept... and I use a laptop... my solution? I asked them for an Apple laptop. Never have to fuss about my wireless card, never have worries about viruses, never have to fret about updating... best thing that IT ever did for me.
