Access control systems protect everything from office buildings to apartments, and even data centers and internet sites. This guide explains the various aspects of access control systems, including their types, components, implementation techniques, advantages, disadvantages, trends, and industry best practices. Whether you are a company owner, a security professional, or just interested in improving security, this one-stop guide will provide you with everything you need to know.
Introduction to Access Control Systems
Access control is a security measure which restricts the number of people and things that are allowed to access a facility or resource. They are critical for safeguarding physical assets such as buildings and rooms, but also digital assets such as data and networks. As they monitor and control access, these solutions stop unauthorized entry, reduce risk, and make sure only authorized users have access to certain areas or data.
Types of Access Control Systems
There are various categories of access control systems in terms of how they operate and the type of access that they control. Learning about types helps you choose the right system based on specific security requirements.
Physical Access Control
Key-Based Systems
Traditionally, key systems utilize actual keys to unlock doors. Though easy and inexpensive, they’re vulnerable to theft of keys or illegal copying.
Card-Based Systems
Card-based systems use access cards or fobs that have RFID or magnetic strips on them. They provide more control and are easy to administer, so that access permissions can be easily removed or altered.
Biometric Systems
Biometrics employ biological fingerprints, facial recognition or iris scans to authenticate people. They are highly secure in that access is restricted to authorized users only.
Electronic Access Control
Electronic access controls use electronic devices like keypads, cards, and electronic locks. They are flexible, and can be combined with other security systems to provide full protection.
Cybersecurity Access Control
In the online world, cybersecurity access control controls access to information, apps and networks. It contains authentication protocols, firewalls, and role-based access control (RBAC) to guard against unwanted digital access.
