- Authentication and authorization are the two processes that make up network security. The first step, authentication, is comparable to how we use access cards to verify that only individuals with permission to enter a building do so. In other words, authentication confirms that the user attempting to access or enter the network is truly a member of the network, avoiding unlawful intrusions.
- Then comes permission. This step determines the level of access that the recently authorised user will have. The network administrator, for example, need access to the entire network, whereas individuals who work on it most likely only require access to specific sections. The process of deciding the level of access or permission level based on the network user's role is known as authorisation.
