Difference between Right , Permission and Policy

 

Rights, permissions, and policies are fundamental concepts in access control and security management, but they serve distinct purposes and are applied at different levels in computer systems and networks. Here's a breakdown of the differences between them with examples:

1. Rights:

• Purpose: Rights refer to the specific actions or operations that a user or group of users is allowed to perform on a particular resource. They define what someone can do with a resource.

• Scope: Rights are typically applied at the resource level and are specific to that resource.

• Example: In a file system, you can assign rights to a user or group on a specific file or folder. For instance, you can grant User A the "Read" right on a document, allowing them to view its contents but not modify or delete it.

2. Permissions:

• Purpose: Permissions are a set of rights collectively assigned to a user or group on a resource. They determine the overall access level for a user or group concerning a resource.

• Scope: Permissions are also applied at the resource level but encompass multiple rights.

• Example: In a file system, you can set permissions on a shared folder. These permissions might include allowing the "Sales Team" group to have "Read" and "Write" permissions on the folder, which means members of the Sales Team can view and edit the files within that folder.

3. Policies:

• Purpose: Policies are sets of rules, guidelines, or configurations that define how a system, network, or users should behave or how security measures should be enforced across a broader context.

• Scope: Policies are applied at a broader level, governing the behavior or security posture of users, systems, or devices across the entire network.

• Example:

  • Password Policy: A password policy is a set of rules that dictate how user passwords should be created, maintained, and enforced. For example, a policy might require passwords to be at least eight characters long, include a combination of letters and numbers, and expire every 90 days.
  • Group Policy: In a Windows domain environment, Group Policy allows administrators to define and enforce configurations for all computers and users in the domain. This can include security settings, application restrictions, and desktop configurations.

Differences with Examples:

Let's illustrate the differences between rights, permissions, and policies further with examples:

• File Permissions (Permissions): Assigning "Read" and "Write" permissions to a group on a shared folder (Permissions) determines what actions group members can perform on the files within that folder. It combines individual rights into an overall access level.

• User Rights (Rights): User rights, such as "Logon Locally" or "Shut Down the System," specify specific actions or privileges that a user or group has on a computer.

• Password Policy (Policy): A password policy (Policy) sets rules for all user passwords across a domain, defining the minimum length, complexity requirements, and password expiration. It governs password management practices network-wide, rather than specific resource access.
