Controlled Access to Confidential Data Is Crucial

If your company is involved in data that is considered private or confidential, having control over access to the data is crucial. Access control is essential for any organization that has employees who connect to the Internet. At its simplest, access control is an individual restriction of information to certain people and under specific conditions according to Daniel Crowley, head of research for IBM’s X-Force Red team that focuses on data security. There are two main components: authentication and authorization.

Authentication involves ensuring that the person trying to gain access to is the person they claim to be. It also includes the verification of passwords or other credentials that must be provided prior to granting access to the network, application or file.

Authorization is the act of granting access based on a certain function in the business for example, marketing, HR, or engineering. The most effective and widely used method to restrict access is to use the use of role-based access control. This type of access is controlled by policies that define the required information for certain business tasks and assigns access rights to the appropriate roles.

If you have a standard access control policy in place, it can be easier to monitor and control changes as they occur. It is important to ensure that policies are clearly communicated to staff to ensure the proper handling of sensitive information, as well as to have an procedure for removing access when employees leave the company, changes their role or is terminated.
