Controlled Access to Confidential Data Is Crucial

Access control to data is vital for businesses that have sensitive or proprietary information. Every company with employees who connect to the internet must have robust access control measures in place. The most basic definition of access control is an exclusive restriction of information to a specific 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, authentication and authorization.

Authentication is the process of verifying that the person to whom you are trying to gain access to is who they say they are. It also involves the verification of passwords or other credentials that must be supplied prior to granting access to an application, network or file.

Authorization refers to the granting of access to a specific function in the business for example, engineering, HR or marketing. Role-based access control (RBAC) is one of the most common and effective ways to limit access. This kind of access is controlled by policies that specify the required information to carry out certain business functions and assigns access to the appropriate roles.

If you have a standard access control policy in place it will be easier to monitor and control changes as they happen. It is crucial that policies are clearly communicated to staff to ensure that they handle sensitive information carefully. There should also be procedures in place for removing access from employees who quit the company, change their role, or are dismissed.
