    I wouldn't say this type of thing is in its infancy. There are quite a
    few tools that can provide the types of things you want to accomplish.
    What doesn't exist, yet, is a single tool that can do all of those
    things. 
    
    Some of those features are included in RealSecure Desktop Protector.
    Anti-Virus DAT files can be checked. If they are older than a specific
    date, the user is prompted to update them and/or the firewall can block
    access to the corporate network. Little tricky to implement however. You
    can also do application level controls as well. All apps on the machine
    are hashed and any changes prompt the user. You can control all this
    centrally through Site Protector. 
    
    
    Patch levels can be easily assessed via MS tools. MS patches can be
    deployed via their SUS server. However its functionality is somewhat
    limited. Might want to look at Hf CheckNet or Patchlink for larger, more
    robust patch-deployment. You can easily audit patch levels with their
    baseline analyzer. There are other assessment tools that can accomplish
    the same thing. Eeye's Retina scanner can do some of that, and its fast
    as hell. 
    
    You might also want to look into Sygate's desktop solution. They have
    some unique features to their desktop firewall that can do some in-line
    filtering. Their product is a little cumbersome, however. But, I have a
    few clients who like it. 
    
    SSL VPNS are generally not going to reach to far into the OS. The whole
    idea behind an SSL VPN is that it has a very lightweight front end. What
    the SSL VPNS are doing is controlling access to specific applications
    via protocols. 
    
    There are quite a few options in this space. Ideally, you might want to
    put together a comprehensive desktop control / security program.

    I would like start a discussion in reference to the validation of remote
    users anti-virus DAT files, patch levels, installed software and so on.
    My understanding is that the technology associated with doing this type
    of thing is in it's infancy. Cisco is working on their admission
    control, Microsoft has their Quarantine server along with 2003 IAS, Zone
    Labs has a product and I've heard some talk of SSL based VPNs
    implementing some of this functionality but none of these really meet my
    needs. I suppose the Zone Labs product would work if it didn't
    constantly crash machines!
    
    The Quarantine thing pretty looks good except many of us are concerned
    with the security of an MS VPN solution and we've got non-Windows
    machines that need to connect. I assume that a bolt-on solution would be
    much more attractive for most of us.
    
    Your opinions, thoughts, advice, etc. would be very much appreciated!
