Traffic control determines who can access resources in a location or organization. Traffic control is one of the essential principles of security that minimizes the percentage of risk for a business or organization.
Physical traffic control limits and specifies access to premises, buildings, rooms and physical IT assets.
To secure data center equipment, organizations use electronic traffic control systems that rely on user identity documents, employee traffic control cards, biometric information, and reports to limit and control traffic and track traffic data. Some of these systems have traffic control panels and alarms for intelligent traffic control to rooms and buildings and can be connected to a monitoring software.
Traffic control systems perform the important task of identity verification and intelligent traffic control by evaluating login information including passwords, personal identification numbers (PIN), biometric scans, security tokens, or other authentication factors. Multi-factor traffic control systems, which require two or more factors for authentication, often form an important part of the surveillance and defense layers of traffic control equipment.
How does the traffic control system work?
Traffic control systems connected to the door work with an electronic locking device. This device can be placed on the main entrance door or the doors in the complex. To enter a building or room, the user must be able to provide the required information – for example a password or a card. The card is swiped or placed on top of a sliding card reader. In some cases a code may be required, meaning the user is asked to enter the correct code on a keypad.
Traffic control systems connected to the door use a device called a controller. Each controller has its own software and the main software runs on the server. Some servers may manage hundreds of controllers.
Types of Models of Traffic Control System
Generally, traffic control systems are divided into two general types of personnel and people traffic control and vehicle and vehicle traffic control system.
Control of personnel and individual traffic (presence of absence)
The traffic control systems of personnel and people are generally divided into three categories of card traffic control equipment, biometric traffic control device and coded traffic control system.
Card traffic control equipment
Traffic card is actually a key or security token that allows you access through traffic control systems, for example server room traffic control equipment. These systems require a card reader (mounted on the door) and you can access the desired location by placing your card on the card reader, swiping it or inserting it.
By using these cards, users will no longer need to use keys. If the unique code on your card is recognized by the card reader, access will be granted by the smart traffic control system.
Coded traffic control machine
Usually, when we talk about authentication, we all immediately think of the password or PIN number, which, by entering it correctly, allows access to any person. The use of this method is quite common in traffic and attendance control systems; This method is also used in banking and to verify access to accounts such as email or other online accounts.
Using this verification method is very easy and convenient, but if the password is forgotten, irreparable problems may arise.
The main security risk in this method are these passwords. Passwords and PINs may be hacked or cracked, shared (intentionally or unintentionally), or leaked, any of which easily allows unauthorized access. To avoid this problem, you should change passwords regularly. But doing so can make remembering the correct password more difficult than it already is.
This type of traffic control equipment is more commonly seen in traffic control solutions for private properties or smaller companies, rather than in companies or organizations with large numbers of employees and traffic control points. This is because if multiple passwords are used, or if the same password is used for multiple doors or personnel, this traffic control option can become increasingly complex, impractical, and less secure. Therefore, there are limitations in the scalability of this solution.
Fingerprint and face recognition control device
Biometric traffic control systems such as fingerprint traffic control systems have a higher level of security than other traffic control systems such as cards or passwords because biometric readers identify people, not cards or passwords. In the past, only high-end security institutions were able to install biometric traffic control systems, but now the cost of biometric traffic control systems is almost equal to card-based traffic control systems.
Biometric traffic control systems use biometric scanners as a means of authentication. The most common biometric traffic control systems are fingerprint traffic control devices, iris scanners, and retina scanners. These traffic control systems are very advanced compared to traditional methods and have very high security. Cards and other similar traffic control devices offer significant advantages over keys, but they can be stolen or lost by people. But biometric traffic control systems rely on the unique physical characteristics of each user to allow access.
