    Find a plug, have fun! (full network access)
    Simple Certificate check for wireless network access, some wired network access (conference rooms)
    Cisco Clean Access implemented, torn out on main campus
    Primary ‘filter’ today: facility security, escort policies
    Challenge One: Access Control, Managed Networks
  • 25. 802.1X now a critical dependency

    Note: Gartner/Burton feedback…
    Solution: 802.1X PNAP
  • 26. …implementing a NAC architecture is not simple… the promise… is still mostly in the future.

    Challenge 2: Managing Off-Network Devices
  • 28. Don’t manage them!
    (shot down)
    Establish SSL VPN connection at logon

    Open Source
    Options to Consider…
  • 29. Upsides of DirectAccess
    Seamless user experience
    Seamless management experience
    IPv4 resources!!! No-go without NAT64/DNS64 services – must have UAG

    Unknown quantity
    No internal/3rd party expertise identified
    More on DirectAccess…
  • 30. Moving slowly…
    MSFT engaged for POC
    Major uncertainty (and RISK!)
  • 31. The fear…
    Keyloggers on unmanaged devices capturing username/password, compromising other externally published applications (OWA, SharePoint, etc.)
    Potential solutions:
    Computer Associates UCG
    visionapp’s vSL
    ‘Honey Pot’ (reverse encrypt-able credentials database)
    Agents on each AD Domain Controller
    Challenge 3: No Passwords Outside the Perimeter
