Abstract
Contagion isolation and inoculation is disclosed. In some embodiments, a request is received from a host, e.g., via a network interface, to connect to a protected network. It is determined whether the host is required to be quarantined. If the host is required to be quarantined, the host is provided only limited access to the protected network. In some embodiments, a quarantined host is permitted to access the protected network only as required to remedy a condition that caused the quarantine to be imposed, such as to download a software patch, update, or definition; install, remove, and/or configure software and/or settings as required by a policy; and/or to have a scan or other diagnostic and/or remedial operation performed. In various embodiments attempts to communicate with hosts not involved in remediation are redirected to a quarantine system, such as a server, that provides information, notices, updates, and/or instructions to the user.
