Controlled access to data is crucial if your business has confidential or proprietary information. Access control is a must for any business that has employees who connect to the internet. In its most basic form, access control is an individual restriction of information to certain individuals and under certain conditions, says Daniel Crowley, head of research for IBM’s X-Force Red team, which focuses on data security. There are two primary components: authorization and authentication.
Authentication is the process of ensuring that the person trying to access is the person they claim to be. It also involves the verification of using a password, or other credentials required before allowing access a network, an application, system or file.
Authorization is the process of granting access based on a certain job in the company, such as engineering, HR or marketing. The most efficient and well-known method to restrict access is to use role-based access control. This kind of access is governed by policies that specify the data required to perform specific business functions and gives permission to the appropriate roles.
If you have a standardized access control policy in place, it can be easier to monitor and control changes as they occur. It is essential that policies are clearly communicated with staff to ensure that they handle sensitive information with care. There should also be an established procedure for removing access to employees who quit the company, change roles or are terminated.
