In 2006, three ski patrol members were killed at Mammoth Mountain ski resort after falling into a snow depression surrounding a volcanic fumarole and filled with cool CO 2 gas. High concentrations of CO 2 gas in soils can also damage or destroy vegetation, as is visible in several areas on Mammoth Mountain.
ID Control's USB Token is a portable end-user authentication token that can replace user name and password for workstation, website, VPN, file, email, network, file and/or disk access security. ID Control USB Token plugs into any standard USB port and can even run without any software. Since authentication products come in various form factors, the user selection process is based on ease of use and flexibility, especially when in remote locations.
For example, when a user who belongs to a Windows domain logs onto the network, his or her identity is verified via one of several authentication types. Then the user is issued an access token, which contains information about the security groups to which the user belongs. When the user tries to access a network resource (open a file, print to a printer, etc.), the access control list (ACL) associated with that resource is checked against the access token.
