Abstract: Evaluating computers, devices, or endpoints on a network, such as a large network of computers in an enterprise environment. Detecting computers, devices, or endpoints that may present a security risk to the network or may be compromised in some way. Generating network traffic that, in some cases, should be ignored or should prompt specific, known responses. Detecting endpoint(s) that respond to such network traffic in an anomalous way, or otherwise attempt to perform certain operations based on such network traffic.

Abstract: Various embodiments of the present technology relate to methods and systems for securely transferring securities and for preventing naked short selling of securities. In some implementations, the system receives inventory securities available for pre-borrowing and authorizes placement of a right to pre-borrow the one or more securities at an auction administered by an alternative trading system. The securities that are auctioned to a bidder are then received into a first addressed account associated with the token generator. In response to receiving the securities into the first addressed account, the system generates a token indicating one or more borrowing parameters. Upon receiving notification from the alternative trading system that the token is matched with a bid, the system cryptographically signs a transaction to transfer the token to a second addressed account associated with the bidder. Thereafter, if the bidder so chooses, the token can be sold to other customers.
