Authorization

Authorization is the act of granting or denying access to a resource or action based on user identity. It is important for protecting data, enabling customization, and establishing trust. Authorization can be applied to various types of resources and actions, and there are different methods and tactics for implementing it. Permissions, rules, attributes, and scopes are some common techniques. Overall, authorization ensures security and efficiency in the use of data and services. Hello and welcome to the TechTalks Podcast, where we discuss the latest trends in services and the world of tech companies. I am your host, Ebenezer, and today we are going to talk about Authorization. Authorization is the period of granting or denying access to a resource or an action based on the identity and goodwill of the user or system. Authorization is closely related to authentication, but there are other things. Authentication is about verifying who you are, while authorization is about what you can do. In this episode, we will cover some of the basic concepts and methods of authorization and why they are important for ensuring the efficiency and benefits of the data and services that they provide. We will also explain some of the challenges and limitations of authorization and how they can be addressed and overcome. To help us with the topic, we have invited a special guest, Godfrey, who is an expert in authorization and security. Godfrey, welcome to the show. Thank you, Ebenezer. It's a pleasure to be here. So Godfrey, can you tell us what is authorization and why is it important? Sure, Ebenezer. Authorization is the act of enforcing rules and policies that determine what a user or a system can or cannot do with a resource or an action. For example, when you log into a website, you may be authorized to view your profile, edit your settings, or post comments, but not delete other users' accounts, access their data, or modify their website code. Authorization is important for several reasons. It protects your data and services from some authorizations such as misuse. For example, if someone hacks your email account, they may be able to read your message but not to send emails on your behalf, change your password, or delete your account. Authorizations can prevent this by limiting the actions that can be performed by different users or systems. Authorization also enables differentiation and customization of your experience. For example, when you log into a website, it may show you different content, features, or options based on your role, preference, history, and permissions. Authorization can also enable users better role-based access control, which allows you to assign different levels of access to different users or groups. It establishes trust and accountability between users and systems. When you make an online transaction, authorization can ensure that both parties have the right users and that the transaction is valid and secure. Authorization can also provide audit through a log that can be used to monitor a compliance report. That's very interesting, Robert. Can you give us some examples of how authorization works in practice? Sure, Ebenezer. There are different types of resources and actions that can be subject to authorization, such as data. This includes files, documents, databases, records, messages that contain information that may be sensitive, confidential, or proprietary. Services. This includes applications, APIs, functions, processes that provide functionality or perform operations that may be critical, costly, or risky. Devices. This includes hardware, software, networks, sensors that enable communication or interaction with other systems or users. Locations. This includes physical or virtual spaces that may have restricted access or require special permissions. There are also different methods and tactics that can be used for authorization depending on the level of security and granularity required. Some of the common methods and tactics are permissions. These are binary flags that indicate whether a user or a system has the right to perform a specific action on a specific resource. For example, a permission may say that only the owner of a file can read or write it. Rules. These are predefined sets of permissions that are assigned to users or groups based on their functions or responsibilities. For example, a rule may state that only administrators can create or delete user accounts. Attributes. These are properties or characteristics of the user, the resource, the action, or the environment that can be used to evaluate policies that determine whether access should be granted or denied. For example, an attribute may state that only users who are managers and who are located in the same office as the resource owner can access a certain file. Scopes. These are parameters that define the extent of access that is granted by users to a certain file application without sharing their credentials. For example, when you log into your website using your Google account, you may see a list of groups that the website requires from Google, such as your email address, group application, contact, etc. Wow! Perfect. That's very informative. Thank you for sharing your knowledge with us. You are welcome, Ebenezer. I hope it was helpful. It certainly was. And that's all we have time for today.
