Study Notes

Access control vestibules are small rooms used by organizations to regulate access to secure areas, such as data centers.
These rooms typically have multiple doors: one leading to the secure area and one or more leading to the vestibule itself.
Access to the vestibule may be controlled through various means, including unlocked doors, badge readers, or biometric authentication.
Once inside the vestibule, individuals may be required to provide additional authentication or clearance before entering the secure area.
Some vestibules have features that limit the number of people able to enter at once, ensuring that only authorized individuals gain access.
Proximity cards, often used in combination with door locks or access readers, are a common security feature.
These cards can be magnetic or use radio frequency identification (RFID) or near field communication (NFC) technology to grant access.
Video surveillance systems, also known as closed circuit television (CCTV), are common security measures in secure environments.
Such systems can provide live or recorded footage of areas, as well as capabilities such as license plate recognition or facial recognition.
Alarm systems are another common security feature, designed to alert security personnel of unauthorized access or other security breaches.
Door locks, which can be conventional, electronic, or biometric, are used to secure doors and prevent unauthorized entry.
In data centers, racks may be securely locked to protect the equipment inside.
Security guards are employed in many facilities to provide on-site security, including checking identification and granting access to authorized individuals.
