    • A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine server located on a trusted machine in a network provides a bill of health to a quarantine agent located on a client computer that wishes to gain access to network resources administered by an organization. The quarantine agent requests bill of health from the quarantine server, and receives a manifest of checks that the client computer must perform. The quarantine agent then sends a status report on the checks back to the quarantine server. If the client computer is in a valid security state, the bill of health is issued to the client. If the client computer is in an invalid state, the client is directed to install the appropriate software/patches to achieve a valid state. When a client requests the use of network resources from a network administrator, the network administrator requests the client's bill of health. If the bill of health is valid, the client is admitted to the network. If the bill of health is invalid, or if the client does not have a quarantine agent, the client is placed in quarantine, in which the only network resources accessible to the client are those necessary to install the quarantine agent and requisite software/patches to achieve a valid state.
    • 提供了一种用于确保具有无效或损坏状态的机器被限制访问网络资源的系统和方法。 位于网络中的受信任计算机上的隔离服务器为位于客户端计算机上的隔离代理提供健康清单,希望访问组织管理的网络资源。 隔离代理从隔离服务器请求健康状况,并收到客户端计算机必须执行的检查清单。 然后,隔离代理将检查的状态报告发送到隔离服务器。 如果客户端计算机处于有效的安全状态,则会向客户端发送健康证明。 如果客户端计算机处于无效状态,客户端将被指示安装相应的软件/修补程序以实现有效状态。 当客户端请求网络管理员使用网络资源时,网络管理员请求客户的健康状况。 如果身体健康状况有效,客户可以进入网络。 如果健康状况无效,或客户端没有隔离代理,则客户端将被隔离,客户端可访问的唯一网络资源是安装隔离代理程序和必需的软件/修补程序所必需的网络资源 达到有效状态。
