Open Supervised Device Protocol is an access control communications standard designed to allow door controllers (on the secure side of a door) to communicate with devices such as card readers on the insecure side in a secure manner, replacing the legacy/insecure Wiegand protocol.

This presentation walks through how it works, how to interface with devices, and most importantly how to review implementations and deployments for security issues where possible, using some randomly selected OSDP capable devices as case studies.
