Cisco and Microsoft released closely held details about their two-year-old partnership to deliver integrated controls that prevent malware-infested computers from connecting into networks. Cisco’s Network Admission Control, or NAC, technology will work with the Microsoft Network Access Protection, or NAP, capabilities available with the upcoming Windows Vista and Longhorn operating systems. The result should be a breakthrough in integrated IT security when the whole package arrives in the second half of next year, the target date for Longhorn’s release.
