You might ask: why access control system if I can do with traditional safety methods like utilization of padlocks, security cameras and alarm system? The answer is simple: such security measures have become obsolete and have a number of drawbacks. Locks can be broken, keys – replicated, security cameras and alarm systems – easily disabled by a halfway tech-savvy thief.
But the most important thing is, traditional security methods do not presuppose authentication and authorization. That means that any person who possesses a key can access any corner of your business facilities. This puts your business at a risk of burglary or insider threat.
As opposed to the traditional security measures, access control system provides a level of security that encompasses everything: from authorization to enter parking lot to access to the server room and confidential information.
Here are arguments why access control is important and the main reasons to use access control systems:
· You can establish control over who has access to your premises by giving personnel access cards/ enforcing biometric readers
· It serves as a single point of control over surveillance cameras, doors, parking lots and as a tool for managing authorization rights of each user
· Having an access control implemented, you can control not only user’s access to assets and premises but also limit employee’s access to sensitive information.
· Some access control systems give you a possibility of audit trails – records of entering and attempts of entering premises by each employee.
· Because cutting-edge technologies enable cloud-based access control, you can manage it remotely from any electronic device with the Internet.
Now that we have touched upon the importance of access control and why access control is superior to traditional security measures, let us have a brief look into the types of access control.
Depending on the mechanism of access control there are distinguished the following types of access control: Discretionary Access Control (DAC), Mandatory Access Control (MAC) and Role Based Access Control (RBAC).
DAC presupposes that an owner of the resource decides what level of access should be given to each individual.
MAC is based on the operating system deciding level of access to certain objects by subjects within an organization. It is a very strict method of access control that can be found in military organizations and other institutions with confidential information.
RBAC is very commonly used these days and presupposes that a user get access to certain premises , software or data depending on a function that person fulfills within an organization. What it means is that each user receives a role based on which they can either get full control, restricted control, ‘read-only’ possibility or no access at all. This gives a higher level of security, as sensitive data can be accessed only by few people and not exposed to all employees.
Now that we have stated the reasons to use access control systems and clarified the importance of access control, you have to choose a reliable provider or access control services and choose a mechanism of access control that suits best your company needs.
