Authentication and authorization are two essential concepts in the realm of cybersecurity and access management. While they often work together to protect systems, they serve distinct purposes and operate in different stages of access control.<\/span><\/p><\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t<\/section>\r\n\t\t\t\t

Authentication<\/b> is the process of verifying the identity of a user or system. It ensures that the individual or entity attempting to access a resource is who they claim to be.<\/span><\/p>

Key Points About Authentication:<\/b><\/h4>
  • Purpose<\/b>: Establishes identity.<\/span><\/li>
  • Methods<\/b>:<\/span>
    • Passwords, PINs.<\/span><\/li>
    • Biometrics (fingerprint, facial recognition).<\/span><\/li>
    • Multi-Factor Authentication (MFA).<\/span><\/li><\/ul><\/li>
    • Use Case<\/b>: Logging into a website or system.<\/span><\/li><\/ul>

      Example:<\/b><\/h4>

      Entering your username and password to access your email account is an authentication process.<\/span><\/p><\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t<\/section>\r\n\t\t\t\t

      Authorization<\/b> determines the level of access or permissions granted to a verified user or system. It answers the question, \u201cWhat are you allowed to do?\u201d<\/span><\/p>

      Key Points About Authorization:<\/b><\/h4>
      • Purpose<\/b>: Controls access to resources.<\/span><\/li>
      • Methods<\/b>:<\/span>
        • Role-based access control (RBAC).<\/span><\/li>

        • Attribute-based access control (ABAC).<\/span><\/li><\/ul><\/li>
        • Use Case<\/b>: Allowing access to specific files, applications, or functionalities after logging in.<\/span><\/li><\/ul>

          Example:<\/b><\/h4>

          Once logged into your email, authorization dictates whether you can read, delete, or modify messages.<\/span><\/p><\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t<\/section>\r\n\t\t\t\t

            1. A user logs into a corporate VPN (authentication).<\/span><\/li>
