Abstract
To isolate a terminal from a network immediately after a quarantine agent is uninstalled therefrom, a policy readout unit reads out a policy from a policy database and a policy check unit determines whether or not a terminal satisfies the policy that was read out. If it is determined that the terminal satisfies the read out policy, a quarantine server control unit instructs a bridge to destroy a packet with no VLAN tag among the packets sent from the terminal while controlling a quarantine agent to send a packet with a VLAN tag when sending the packet from the terminal.
