What is an Access Control System?

Access control systems are essential for managing who can enter specific areas within a facility. They are critical for ensuring security in environments ranging from corporate offices to government installations.

Reads access credentials from key cards or fobs locally and then relay the read information (typically a number) to the controller

Receives card numbers and ultimately makes the yes or no decision to trigger the relay, which will unlock the door. These are typically expensive and only support four doors or less

Credentials

Credentials

Magnetic Lock (Maglock)

Magnetic Lock (Maglock)

A magnetic lock that uses an electromagnet to lock doors hold the door "locked." However, if the power goes out, these are programmed to fail-safe, or "unlocked" for the layperson

Electric Strike

Electric Strike

A solenoid powered strike that will "unlock" when power is applied. Unlock the the maglock, these are fail-secure when the power is off and do not require exit buttons or motion sensors

Exit Button

Exit Button

Because maglocks will hold the door shut when powered, buttons are required on the interior to let people escape in emergencies

Motion Detector

Motion Detector

Similarly, for maglocks that hold the door locked when powered, motion sensors let people exit the building without much hassle

Motion detectors use infrared, microwave, or ultrasonic waves to detect movement and trigger actions like opening doors or sounding alarms, but can be exploited by actions like vaping, mitigated by additional verification methods and sensor adjustments

Wiegand Protocol

Wiegand Protocol

The most popular communication standard for data transmission between card readers and controllers. It is unencrypted and therefore vulnerable to man-in-the-middle (MitM) attacks


The Wiegand protocol, a widely adopted communication standard for data transmission between card readers and controllers, uses pulses to transmit binary data but is vulnerable to man-in-the-middle attacks due to clear text transmission, which can be mitigated by transitioning to secure protocols like OSDP

Open Supervised Device Protocol (OSDP)

Open Supervised Device Protocol (OSDP)

The OSDP protocol was meant to enhance security and interoperability in access control systems through bi-directional communication and encryption

The OSDP protocol enhances security and interoperability in access control systems through bi-directional communication and encryption, allowing secure data exchange and better device monitoring, though it can still be exploited if encryption keys are compromised.

Your private keys are stored in the Secure Element (SE) on the phone — the same technology in DoD-grade smartcards. Bluetooth connections reduce friction while maintaining best-in-class security. Additionally, TrustZone and biometrics are leveraged to prevent relay attacks, software exploits, physical tampering, and device theft.
