  1. Re:What is the drawback to this security method? on 1 In 3 Windows PCs Still Vulnerable To Worm Attack · · Score: 1

    Not really, we have an SSL VPN which we can use to grant external access if needed, and for one or two users we do have 3rd party remote support software enabled. Access is generally granted a day at a time, and it's a few seconds work to enable it as needed.

    Yes, there's still a risk of a work related site being infected, but bear in mind that to infect us it's got to get past:
    - A work related site must be infected (generally quite specialist sites, without a lot of traffic, so not prime hacking targets)
    - That site must also be one on our trusted list and able to run scripts
    - The virus scripts have to be running from that site (and not just redirected from elsewhere)
    - The virus can't download anything (we whitelist file downloads too - executable content isn't allowed)
    - The virus will have to be able to work with user permissions
    - It will also have to avoid a very up to date AV install and firewalls on our individual machines.

    Generally, anything that can get past that lot is going to be very new, and probably capable of infecting our machines using current 0-day vulnerabilities.

    However, so far we've been lucky, and yes, I do consider it luck. While I think ours is better than most, no AV protection scheme is perfect and I think it's only a matter of time until we do get infected by a virus. That's why we're looking to improve our backups and response times. All our work and servers are thoroughly backed up, the next stage is to improve backups of desktop computers so that we can recover from a site wide virus outbreak in a couple of hours.

    The aim here is not to stop infection completely, that's impossible, our aim is to reduce downtime. We've done the first step which is to minimise our risk of infection, the next step is to minimise the recovery time when that happens.

    > Do you really expect us to believe that the only secure way of accessing an Office Doc is to quarantine it.
    > I thought you had the system totally locked down and AV on all desktops?

    As far as I'm concerned, yes. There are far too many vulnerabilities in office docs, and no way for me to lock those programs down. The primary aim of our security practices is to stop malware coming into the building, once it's in we're pretty much screwed. AV is the last line of defence, and one I don't particularly trust these days.

    Blocking executable viruses and securing the web browser is easy. Securing Outlook and Office programs is a pain, but fortunately it's not proving too much hassle to manually vet these and we catch 5-6 documents a week that aren't caught by the AV scanning on our email gateway.

    I just don't trust AV scanning these days, there's always a window of opportunity for any new virus, and too many viruses are sneaking in under the radar. In the last 18 months I've submitted four previously unknown viruses to the AV companies, two of which weren't detected at all by either Sophos, Symantec or AVG after booting from recovery CD's.

    > What are those specialist apps. Do you mind telling me what sector your business is in?

    Our sector - structural steelwork, and off the top of my head a quick list of some of our specialist software would be: AutoCAD, Design Review, Strucad, Xsteel, GoData, Farm Design, Multisuite, Procad, Fabtrol, Dema, Union2, Fastrak, Tedds.

    None of these are minor, most are absolutely core programs that are vital to our business. To the best of my knowledge, *none* are available under Linux, and at least 4 require some serious graphics capabilities that rule out virtual machines or wine.

    Everything :-) I'm your proverbial jack of all trades, responsible for:
    Servers, Databases, Intranet, Security, Backups, Software Development, Helpdesk, Software Installation, Printers (up to A0), Fax machines, Scanners

    We have 13 servers and over 100 individual pieces of software on this network. There are also a further 20+ legacy in house applications in use (mainly visual C++ v5, with the odd visual basic v5 one), and about half a dozen modern ones (developed with visual studio .net or 2005). We have five database servers, a wiki, an intranet, an email server, two firewalls. We run Windows (NT - 2003), Linux, OpenSolaris and ESX, with the Citrix server having been retired.

    And believe me, I've simplified things wherever possible. This network is horribly, horribly complex. It took me nearly two years to familiarise myself with it, and we really do use everything I've

    lol, trust me, it would take a lot longer to get this network working under linux than windows, and that's before you count the couple of dozen specialist apps that simply don't exist in Linux. Linux is good, but it really isn't the answer to everything. I'm not aware of anything that as easy to use and effective as group policy for securing computers and deploying software. I can rollout new versions of some of our apps to 100+ computers in under ten minutes of my time (and that includes the download!).

    Having said that, my own workstation is running Ubuntu 8.10, and we have a good few Linux servers now :-)

    However, I think you'd be surprised just how low maintenance this lot is. Yes, it took some setting up, but we're reaping the benefits now. To give just one example, patching software is something we can do in our own sweet time, even though we use WSUS we run 2-3 months behind and let other people do the testing :)

  6. Not patched, not worried on 1 In 3 Windows PCs Still Vulnerable To Worm Attack · · Score: 1

    As I've said many times, patches are nowhere near as high a concern if you lock things down in the first place, and Microsoft do provide some pretty good tools for doing that in Windows (namely Group Policy).

    Our protection against viruses is pretty thorough, and we've not had a sniff of an infection in 3+ years:

    - All of our machines have filtered access to the outside world
    - Staff can only visit work related sites during working hours (enforced at the firewall)
    - No website can run any kind of script unless approved by IT (takes 5 mins or so to approve)
    - All CD-ROM drives are disabled on machines.
    - Users do not have permission to install USB drives
    - Autorun is disabled site wide via group policy
    - Downloads of executables, zips, etc is disabled at the firewall
    - Emails are also filtered, and in addition all Office Documents are quarantined before manual release.
    - Oh, and AV on all desktops (Sophos), updating within 15 mins of new virus definitions coming out.

    Over the last 2 years, I've only seen three security warnings from Microsoft which we're not already exempt from because of the mitigating factors, and while this might sound over the top, it doesn't get in the way of our users doing their work, and takes under a single man hour each day for the IT department to manage. Quiet days probably only take up 15 mins or so.

    Although to be honest, I still don't consider this a final solution. Future plans include:

    - Whitelisting of all executable software
    - Full DR procedure for desktops (to allow quick recovery when we do get hit by a virus)
    - Physical isolation of key machines to protect them in case of an outbreak

It's an obvious way to combat piracy since you can identify the source of the leak, and it's a massive benefit that digital distribution offers the record labels. Users get cheaper tracks and can download them instantly from the comfort of their own home. Record labels get to discourage piracy and have an easy way to track down the source when it happens.

    Honestly, it's such a simple solution I thought there must have been something I was missing for the record companies to not implement this. It's win win as far as I can see.

    I agree, the ribbon was a great idea. However, the major problem I have with it is that it breaks UI consistency on the windows platform. Up to now, Microsoft have pushed a consistent UI design for all windows apps, and that is one of the hidden strengths of windows, with their own apps being pretty much flagships for the best practices.

    With Office 2007 this has all been thrown out of the window. Now one of the flagship apps for the operating system completely ignores the recommended UI design, and worse, it's own design is patented and protected and developers are prohibited from using that design for any competing software.

    That is why I'm against introducing Office 2007 in our organisation. Keeping a consistent UI across multiple programs means we don't need to worry about training our staff, and trust me, two types of UI would *really* confuse some of our users.

    Now had they done it properly, and introduced the ribbon as a new recommended UI for windows, with Office 2007 demonstrating how it should be used, I would have been all for the idea. Unfortunately, Microsoft as usual put marketing, sales and legal ideas ahead of anything technical, practical, or secure.
