Authentication vs Authorization: Difference Between Authentication and Authorization

Differences Between Authentication and Authorization

Below is an overview of the differences between authentication and authorization.

The Importance of Robust Authentication and Authorization Processes

According to a survey by GoodFirms, 30% of IT professionals surveyed reported experiencing a data breach due to weak passwords, and two-thirds of Americans use the same password across multiple accounts. According to a study by the Ponemon Institute, 71% of end users said they often had access to data they shouldn’t see, and 80% of IT professionals believed their firms were not enforcing strict data access privileges.

These alarming statistics highlight the risk posed by poor authentication and authorization protocols, which often include the use of passwords that are short, easy to guess, or vulnerable to cracking methods such as credential stuffing. The combination of authentication and authorization is fundamental in establishing a secure system. By verifying the identity of users and services and controlling their access rights, these processes work together to protect against unauthorized access, data breaches, and other security threats.

Common Authentication Methods

Traditionally, user authentication involved a username and password combination. Modern authentication methods, however, typically leverage three classes of information, which include: something you know, something you possess, and something you are.

Something you know: This commonly refers to a password but can also include security questions or one-time pins.

Something you possess: This can encompass mobile devices, security tokens, or digital IDs.

Something you are: This typically pertains to biometric data such as fingerprints, retinal scans, or facial recognition.

Often, these elements are combined for multi-layered authentication. For instance, a user may input a username and password for an online purchase, followed by a one-time pin sent to their phone as an additional security measure. By integrating various authentication methods with consistent protocols, organizations can uphold security while ensuring compatibility between systems.

Common Authorization Methods

Authorization controls are applied after user authentication to ensure users can access data and perform specific functions. Permissions can be assigned at the application, operating system, or infrastructure levels. Two common authorization techniques are role-based access control (RBAC) and attribute-based access control (ABAC).

Role-Based Access Control: RBAC grants users access to information based on their role, such as allowing employees to view personal information but not modify it, while HR managers may have access to all employees’ HR information.

Attribute-Based Access Control: ABAC grants users permissions on a more granular level, including user attributes, environmental attributes, and resource attributes, allowing more complex authorization processes, such as limiting access to HR data to certain locations or times.

To protect sensitive data and resources, organizations must harden their authentication and authorization processes by implementing multi-factor authentication and enforcing strong password policies. Educating users about security best practices and monitoring access to critical systems and data will also help to maintain a robust security posture.

How Lepide Helps

The Lepide Data Security Platform can help to strengthen your authentication and authorization processes by collecting logon/logoff data from various sources, including both on-premise and cloud-based environments. By identifying excessive permissions, the platform restricts access to confidential data, only allowing users to access the information they need. Additionally, it tracks and manages privileged users, keeping a close eye on their activities. With an intuitive dashboard, it’s easy to oversee logon/logoff activities and manage password resets. Advanced machine learning capabilities detect anomalous behavior in real-time, enabling organizations to respond swiftly to threats. In the event of a security incident, the platform offers a comprehensive event timeline, assisting in forensic analysis and incident response.
