Access Control Situations: Review information from the reading assignment that pertains to identific

An essential idea in computer security is access control, which entails limiting who has access to what data or resources. Identification, authentication, and authorization are the three primary phases of access control.

Step 1: Identification

Identification entails figuring out who the user trying to enter the system is. This can be done in a number of ways, like using a username, email address, or other distinctive identification. At airport security checks, identification is used in real life. Before being allowed to board their flight, passengers are required to show identifying papers at the checkpoint, such as a passport or driver's license, to prove their identity.

Step 2: Authentication

Authentication means confirming the user's identify using a security token, biometric authentication, or a password. Online banking is an example of a scenario where authentication is used in reality. Before being allowed access to their account, users who try to access their online banking account must first input a username and password to prove their identity.

Step 3: Authorization

The final stage of access control is authorization, which involves granting or denying access to specific resources or information based on the user's identity and authentication. A real-life situation where authorization is used is in a company's file-sharing system. Employees are granted access to specific files and folders based on their job responsibilities and seniority levels, which determines the level of authorization they have.

Final Thoughts/Summary

The three stages of access control - identification, authentication, and authorization - are critical in ensuring the security of information and resources. In real-life situations, these stages are used in various ways to control access to sensitive information, such as in airport security, online banking, and file-sharing systems in companies. By implementing strong access control measures, organizations can protect their assets from unauthorized access and prevent data breaches.
