Controlled Access to Confidential Data Is Crucial

If your company is involved in data that is considered proprietary or confidential, limiting access to the data is vital. Every company with employees who connect to the internet must have strong access control measures in place. At its most basic, access control is the selective restricting information to a set of people and under specific conditions according to Daniel Crowley, head of research for IBM’s X Force Red team, which focuses on data security. There are two major components: authentication and authorization.

Authentication is the process of making sure that the person trying to access is who they claim to be. It also includes the verification using a password, or other credentials needed before allowing access a network, application, a system or file.

Authorization refers to granting access to a specific job in the company for example, engineering, HR or marketing. The most effective and common method of limiting access is to use access control based on role. This type of access is controlled by policies that define the required information to carry out certain business functions and assigns access rights to the appropriate roles.

If you have a standardized access control policy in place it will be easier to manage and monitor changes as they occur. It is crucial that policies are clearly communicated to staff to encourage them to be cautious when handling sensitive information. It is also recommended to have an established procedure for removing access to employees who quit the company, change their position or are terminated.
