Claim Text:
1. A method for securing an accessible computer system, the method comprising: counting, at a switch that performs load balancing for access provider systems, a cumulative number of access requests initiated by an access requestor to all of the access provider systems during a first period of time; determining, by the switch, that the cumulative number of access requests exceeds a threshold number, even though a number of access requests to each of the access provider systems alone is less than the threshold number; denying, at the switch, access by the access requestor to the access provider systems in response to determining that the cumulative number of access requests exceeds the threshold number; and restarting a time out period during which the access requestor is denied access based on detecting, at the switch, receipt of another access request from the access requestor before the time out period expires.
