Access control to data is essential if your business has private or confidential information. Any company that has employees connected to the internet should have robust access control measures in place. Daniel Crowley, IBM’s X Force Red team head of research, explains that access control can be used to restrict access to certain people and under certain conditions. There are two main components, authentication and authorization.
Authentication involves ensuring that the person you’re trying to get access to is who they claim to be. It also includes the verification of passwords or other credentials that must be supplied prior to granting access to the network, application, file or system.
Authorization is the process of granting access based on a particular job in the company for example, engineering, HR or marketing. Role-based access control (RBAC) is one of the most popular and effective methods to restrict access. This kind of access is controlled by policies that identify the information needed to carry out certain business functions and assigns access to the appropriate roles.
If you have a uniform possible technologies in the future access control policy, it can be easier to manage and monitor changes as they occur. It is important to ensure that the policies are clearly communicated to staff to ensure that they are careful with sensitive information, and to establish procedures for revocation of access when an employee leaves the business, changes their role or is terminated.
