Abstract
An input port for a computer system may retain potentially authenticable requests for processing while removing other connection requests from an incoming queue or request pool. The input port may continue to receive new requests even during a denial of service attack, allowing potentially legitimate requests to be processed. In a typical embodiment, a first in, first out buffer may be used to receive and process connection requests. When the buffer is full, any request that comes from a device having a previous connection with the computer system may be retained for authentication, while removing requests that come from unknown devices. Some embodiments may retain a list of known devices associated with administrators or other known users, and the list may be updated as those users are authenticated.
