Automatic Access Control Systems (AACS) provide detection and audit to limit who can go where. They can be combined with assured physical barriers to provide delay into a secure site or can be used with demarcation barriers i.e. half height gates, to provide only detection.
An AACS cannot easily be fooled, socially engineered or threatened as a security officer could be.
AACS can control access at the perimeter and also movement within the building.
CPNI assured AACS systems will always consist of at least two separate components:
AACS control system - the “brains” of the system
Token and Reader - the pass you will ask staff to carry and the reader
Each of these components need to be assured products to offer a robust level of security - having a weak lock on the door is as bad as having a weak door.
Tokens and Readers
Tokens, readers and keypads are evaluated under the CPNI evaluation programme. There are three separate evaluation standards and have been produced in conjunction with NCSC. A manufacturer may present any one or any combination of products for evaluation.
AACS can be combined with an assured biometric device to offer a greater level of security, ensuring that the correct person is entering the secure area, not just the correct pass.
