Abstract:
The patent describes a method for "contagion isolation and inoculation." When a host computer requests to connect to a protected network, a determination is made as to whether the host needs to be quarantined. If quarantined, the host is granted only limited access to the network. This limited access is typically sufficient to remedy the condition that led to the quarantine, such as downloading software patches, updates, or definitions. Any attempts by the quarantined host to communicate with other hosts not involved in the remediation process are redirected to a quarantine system, such as a server, which can provide information, notices, updates, and instructions to the user.

Plain-Language Overview of Independent Claims:

After a thorough review of the patent's claims, the following is a plain-language summary of the independent claims:

• Claim 1: This claim outlines a method for managing network security. When a device (host) tries to connect to a protected network, the system checks if it needs to be quarantined. If it does, its access is restricted. Any attempt by the quarantined device to communicate with network resources not essential for fixing the problem (remediation) is rerouted to a special quarantine server.

• Claim 15: This claim describes a physical system designed to perform the security method. It includes a network interface to receive connection requests and a processor. The processor determines if a connecting device should be quarantined, limits its access if necessary, and redirects its non-remediation traffic to a quarantine server.

• Claim 26: This claim covers a computer-readable medium (like a hard drive or CD-ROM) that stores instructions. When these instructions are run on a computer, they cause the computer to execute the security method described in Claim 1: receiving a connection request, deciding whether to quarantine, and if so, limiting access and redirecting traffic.
