Different Types of Access Control Systems
In general, access control is any type of control that regulates the entrance
of a person in a given object. For instance, the PIN code of your credit card is
a type of everyday control that precedes the access to your bank account. The
control can be done by a human being or it may be performed by a computerized
machine using a suitable software program. This phenomenon is also widely used
in everyday life to control the entrance and the exit of people in a certain
building. Moreover, control of the access in a place is done in the workplace in
order to check the punctuality of the workers.
Types of access control
As we already mentioned, there are various types of access control. The first
type is the control found in the residential buildings in big cities. Every big
building has installed a proper access system that prevents people who are
non-residents of the building to enter in it without a suitable permission given
by some of the residents. The second type of entrance control is the control
used in big companies. The management of every company usually installs systems
for controlling the access of their employees. Thus, the employer always has the
needed information about the punctuality and reliability of every single worker.
Moreover, the company may have additional systems for attendance control in
various rooms of the building, which usually protect the important documents and
money from potential robbers. Additional types of control of the access are
ATMs, car locks, hotel locks and many more. The function of all of them is to
secure confidential, serious and important information or equipment.
How does the access control work?
People who want to preserve and keep their important documents and
possessions safe must immediately install some type of access control. The
background operations of this process are pretty complex; nevertheless, the big
picture that is presented in front of us is very simple. For instance, every
single employee in a company has an identification card that helps them enter
the building. The worker uses the card, registers his entrance and freely
attends to his workspace. The background processes that happen behind this
seemingly very easy action are far more complex. For example, every entrance is
added to a log list automatically on a computer. The computer registers the
attendance of the employee and it gives a command to the doors to be opened.
After that, the doors are supposed to be closed and ready for another
employee.
Computer access control
Access control is an action which is very often used for protection of the
important files on computers. For instance, if the user has some files that need
to be hidden from the rest of the users, they can easily limit the access to
those files by giving a simple command. The access will be denied every time the
user does not provide the correct user name and password. Thus, whenever you
want to keep some things in the dark on your computer, you should immediately
use control of the access to the documents in question. The process is easy,
practical and very helpful.
