摘要： A computerized device transmits an access request to a data communications device of a network in an attempt to access network resources within the network. The data communications device, in response and in real-time, transmits a challenge request to the computerized device that directs the computerized device to retrieve configuration, or posture, credentials associated with the computerized device. A policy server receives the challenge response and, based upon a real-time analysis of the posture credentials of the computerized device, determines a security state of the computerized device and either provides some level or denies the computerized device access to the network resources based upon the analysis of posture. The data communications device detects the real-time security state of the computerized device prior to providing the computerized device with controlled access to the network resources, thereby limiting vulnerable computerized devices from accessing the network resources and minimizing the risk that the network resources receive or transmit malware.

摘要： When establishing a communications channel to a wireless network, through a wireless connection, a computerized device receives an Internet protocol (IP) address from a Dynamic Host Configuration Protocol (DHCP) server associated with the wireless network. The computerized device is configured with a table or list of IP addresses associated with wireless networks requiring a VPN or secure connection. The computerized device compares the IP address received from the DHCP server with the IP address entries of the table stored by the computerized device. If the computerized device detects a correspondence between the IP address received from the DHCP server and an IP address entry within the table, the computerized device automatically initiates a secure or VPN connection with the wireless network associated with the DHCP server. The computerized device therefore actively establishes a secure connection with the wireless network, prior to user login and without user intervention, based upon the computerized device being a client of the wireless network.
摘要翻译：当通过无线连接建立到无线网络的通信信道时，计算机化设备从与无线网络相关联的动态主机配置协议（DHCP）服务器接收因特网协议（IP）地址。计算机化设备配置有与需要VPN或安全连接的无线网络相关联的IP地址表或列表。计算机化设备将从DHCP服务器接收的IP地址与计算机化设备存储的表的IP地址条目进行比较。如果计算机化设备检测到从DHCP服务器接收到的IP地址与表中的IP地址条目之间的对应关系，则计算机化设备将自动发起与DHCP服务器相关联的无线网络的安全或VPN连接。因此，基于计算机化设备是无线网络的客户端，计算机化设备在用户登录之前并且没有用户干预，主动地建立与无线网络的安全连接。

摘要： In a virtual private network, a plurality of concentrators form an interface to provide client/remote site access to a private network over a public network. The plurality of concentrators are grouped into a virtual cluster. Each concentrator in the virtual cluster has an IP address and the virtual cluster has a virtual IP address. In operation, one of the plurality of concentrators assumes the virtual IP address and acts as the master device in the cluster. When a client attempts a connection to the private network, the client addresses an initial request to the virtual IP address. The master device responds to the client request by transmitting to the client the IP address of a concentrator in the cluster selected to handle the connection.
