Insiders pose a real threat to the security of data centers. The Chock-o-Lock is an auxiliary security system that uses facial recognition to authenticate users. The system will require the user to authenticate first at the door to the server room and then again to gain access to each individual server rack. The system will log all attempts to access the data center and server racks, along with other important security information. Security teams will be able to easily control who can enter the data center and regulate the number of people in the data center at one time, restrict the access of each user only to the specific server racks they need to work on, audit the logs recording all data center accesses, and gain a clear picture of data center usage.
