For the purpose of this standard, the term communications is understood to include voice, video, and data
communication in all modes including the network infrastructure which supports these communications.
Communications at an airport comes in many forms and the focus of DO-230 is on the communications
systems used to support airport security access control systems. It is important that the needs of all
stakeholders are included in the development of the communication plans. Performing a functional
decomposition of needs is a recommended start as these could be included in the overall concept of
operations of the airport. Airport security systems may utilize some or all of a wired or wireless cellular
telephone and/or trunked radio systems, VHF / UHF handheld devices, IP network technologies connecting
smartphones, and/or tablet devices. Guidance information on communications technology can be found in
Section 9: Communications Infrastructure.
Credentials are identification media issued by an airport or an authorized issuing organization that could be
used to identify individuals. The credentialing process can either be conducted by the Airport authority or
be sub-contracted to an external organization under the direction of the airport. The credentialing process
can issue identification-only media or identification and access control depending on the information
encoded onto the media.
The credentialing process utilizes processes outlined in the PACS infrastructure (see Section 4: PACS for
more information). Privacy is a concern in the credentialing process since the collection and use of personal
information and background checks are requirements of the process. Information on credentials and a
typical credentialing process can be found in the Credentialing section of this document.
Airport access control systems have evolved to include biometric technology as an automated method to
determine the identity of an individual. Biometric technologies include fingerprint recognition, iris
recognition, face recognition, speaker recognition, hand geometry, and vascular / vein pattern recognition.
Access can be denied or granted based on the use of biometric information, which can be encoded within
the carried credential of the person requesting access to a particular area or stored in a central server.
The enrollment and storage of the biometric identifier is typically performed as part of the credentialing
process which is an integral part of an airport’s Identity Management-Credential Issuance System (IdM-
CIS). The use of biometrics within airport security access control systems can be found in Section3:
Biometrics together with best practices for the retention of biometric records and guidance on privacy
The network infrastructure that connects devices such as card readers for door or portal access, field control
panels, databases and software subsystems, wiring infrastructure and servers collectively make up a
Physical Access Control System (PACS). These are a representative sample of components of a PACS
since some airport operators may have more or less components based on their unique requirements.
PACS activities are coordinated with the badging/credentialing process which includes the use of biometric
identifiers and are part of the physical infrastructure of the airport. PACS should therefore be included in
the Concept of Operations, and component guidance is included in the TSA Recommended Security
Guidelines for Airport Planning Design and Construction as well as in Section 4: PACS of this document.
