Which of the following are the types of access controls? Each correct answer represents a complete solution. Choose three.

Physical access controls are tangible barriers and mechanisms - such as locks, fences, security guards, and badge readers - that restrict physical entry to facilities and hardware.

Technical (logical) access controls are hardware and software mechanisms - such as firewalls, encryption, ACLs, and authentication systems - that restrict access to systems and data.

Administrative access controls are policies, procedures, and governance measures - such as security policies, background checks, and security awareness training - that direct how access is managed organizationally.

'Automatic' is not a recognized category in the standard access control taxonomy - the three accepted types are Physical, Technical/Logical, and Administrative per security frameworks such as NIST SP 800-53.
