|Description||Temporarily Quarantine Bot Infected Devices:
ISPs may temporarily quarantine a subscriber account or device if a compromised device is detected on the subscribers network and the network device is actively transmitting malicious traffic. Such quarantining should normally occur only after multiple attempts to notify the customer of the problem (using varied methods) have not yielded resolution. In the event of a severe attack or where an infected host poses a significant present danger to the healthy operation of the network, then immediate quarantine may be appropriate. In any quarantine situation and depending on the severity of the attack or danger, the ISP should seek to be responsive to the needs of the customer to regain access to the network. Where feasible, the ISP may quarantine the attack or malicious traffic and leave the rest unaffected.
