Face up to Biometrics for your SAS70 audit (SAS 70)

Keith Harrell Profile: SAS70ExPERT

Biometric systems are used today not only at your Data center/ co-location facility, but for plain ole’ laptop access. Finger, hand and thumb prints provide you access to all your critical data. In addition, iris/retinal scans and other facial recognition scans provide the credentials required to prevent forgery. What are you using within your Company?


For a SAS 70 audit, critical areas to review related to biometrics are:

1)       enrollment process for a new user

2)       accuracy and monitoring of the biometric device

3)       termination of users


During enrollment, an individual’s biometric template is created in a database. Make sure you have a documented process for adding and authorizing new users to the database. You must know who may authorize access, and how much access to give the new employee.  


Determine the accuracy and monitoring of biometric usage. Review who has used the biometric device, by reviewing the logs an identifying any unusual activity. For example, if you note that Bob has entered the facility 3 times and there is no exit  – then your device may not be working properly.


Last, if Adam quits or Alice is fired, then how do you know to delete her credentials from the system? Make sure Human Resources has a policy to notify you immediately when a person needs to be removed from the system. IT should have a checklist of items/inventory to be returned when employee exits and the form should include a sign-off to indicate removal from the biometric device.
