Access control systems are useful in both physical and IT security. They govern who can enter a system and perform various actions.
Access control will restrict a person’s abilities and permissions based on login credentials (or physical keys), as well as things like the role that the owner of the key has – in the case of more advanced access control systems installation austin.
At its simplest form, a person standing in front of a door with a list of names of people to allow in is performing an access control role. In this case, the restriction is based on who you are. In other cases, the restriction could be based on what you know, or what you own – for example a password, a key, or a dongle.
Access control is a complex issue. You need to make sure that you assign the right roles and that it is easy to remove someone’s rights if necessary. A system where keys are easily copied would be problematic, as would one where there is a complex and large list of permissions and if someone leaves the company or changes roles it is almost impossible to tell whether or not their persmissions are now correct.
That’s why there are so many complex options for access control these days. Key cards which are programmable and that link to a software system which tracks who goes where as well as what that person should be allowed access to are a much better option than physical keys, for example. In the world of software, access control that is based on properties assigned to an account (such as ‘admin’, ‘editor’, or ‘user’) can be more efficient from an administration point of view than software that is set up to require every user’s rights to be managed one by one.
