Controlled Access to Confidential Data Is Crucial

Controlled access to data is essential for any business that has private or confidential information. Access control is an essential requirement for any business with employees who connect to the Internet. Daniel Crowley, IBM’s X Force Red team head of research, explains that access control is a way to limit access to information only to specific people and under specific conditions. There are two major components, authorization and authentication.

Authentication is the process of ensuring that the person you’re trying to gain access to is the person they claim to be. It also involves the verification of the password or other credentials that are required before allowing access a network, application, a system or file.

Authorization is the process of granting access to specific areas based on roles in a business such as engineering, HR, marketing etc. Role-based access control (RBAC) is one of the most popular and effective ways to limit access. This type of access is based on policies that define the information needed to complete certain business tasks and assign permissions to appropriate roles.

It is easier to manage and monitor any changes when you have a policy for access control that is uniform. It is crucial to ensure that policies are clearly communicated to staff to encourage the careful handling of sensitive information, and to establish a procedure for revoking access when an employee leaves the company, changes their role or is terminated.
