6 Types of Authorizations and How to Choose the Best One for Your Company

In today’s digital landscape, ensuring the security and privacy of data is of paramount importance. One crucial aspect of safeguarding data is managing authorizations effectively. Authorizations dictate who can access what within a company’s digital ecosystem, making choosing the right type of authorization for your organization’s needs essential. 

Let’s explore various types of authorizations and how to choose the best one for your company. 

Types of Authorizations

  1. Role-Based Access Control (RBAC): RBAC is a widely used authorization model where permissions are granted based on organizational job roles or functions. Users are assigned roles, and these roles determine their access rights. RBAC is effective for organizations with well-defined job roles and hierarchical structures.
  2. Attribute-Based Access Control (ABAC): ABAC is a dynamic authorization model that considers various attributes such as user attributes, resource attributes, and environmental conditions when granting access. ABAC is highly flexible and can adapt to complex access control scenarios. It is beneficial for organizations with diverse access requirements.
  3. Discretionary Access Control (DAC): DAC allows resource owners to determine who can access them. It’s commonly used in file systems, where the owner decides who can read, write, or execute their files. DAC is suitable for organizations that require fine-grained control over resource access.
  4. Mandatory Access Control (MAC): MAC enforces strict access policies based on security labels or classifications. It’s prevalent in government and military settings where data confidentiality and integrity are critical. MAC is ideal for organizations dealing with highly sensitive information.
  5. Relationship-Based Access Control (ReBAC): ReBAC is a policy model focused exclusively on the relationships or how resources and identities (aka users) are connected to each other and between themselves. These connections are used to implement Authorization- i.e., ensuring that the right people and services have the right access to the right resources.
  6. Permission-Based Access Control (PBAC): PBAC grants access based on explicitly defined permissions. Each resource has a list of authorized users or groups; access is granted to those on the list. PBAC is straightforward and suits organizations with relatively simple access requirements.

Choosing the Right Authorization for Your Company

Selecting the appropriate authorization model for your company involves considering several factors:

  1. Security Requirements: Assess the sensitivity of your data and the level of security required. A model like MAC might be necessary if your organization deals with highly confidential information. However, for less sensitive data, RBAC or ABAC may suffice.
  2. Complexity of Access Control: Consider the complexity of your access control requirements. If your organization’s access needs are straightforward and role-based, RBAC or PBAC may be adequate. ABAC or RB-RBAC might be a better fit for more intricate scenarios involving multiple attributes and conditions.
  3. Scalability: Think about your organization’s growth potential. Will your authorization needs evolve with time? ABAC is highly scalable and can adapt to changing requirements, making it a good choice for growing companies.
  4. User Experience: Consider the user experience for your employees. Complex access control models might lead to confusion and hinder productivity. Ensure that your chosen authorization model is user-friendly and easy to manage.
  5. Policy-Code Decoupling: Lastly, evaluate how well the chosen authorization model can decouple policy from code. Decoupling policy from code allows for more agile development and easier policy changes without altering the underlying codebase.

Permit.io: Decoupling Policy from Code

Permit.io is an innovative authorization solution that excels at decoupling policy from code. With solutions like OPA (Open Policy Agent) and OPAL (the open source projects)  that are actively being accepted across the industry with players like Tesla, this approach offers several advantages for organizations:

  1. Flexibility: Permit.io allows organizations to define access policies separately from their application code. This means access control rules can be modified or updated without code changes, leading to greater flexibility.
  2. Reduced Development Time: By decoupling policy from code, developers can focus on building and enhancing features rather than dealing with complex access control logic. This can significantly reduce development time and costs.
  3. Improved Security: Separating policy from code enhances security by minimizing the risk of introducing code-related vulnerabilities during policy updates. This is especially important in the context of ever-evolving security threats.
  4. Scalability: Permit.io can scale with your organization’s growth, making it suitable for both small startups and large enterprises. As your company expands, you can adapt and refine your access policies without disrupting your application’s core functionality.
  5. Enhanced Compliance: Many industries require strict compliance with data access regulations. Permit.io provides the tools needed to enforce compliance by allowing organizations to define and enforce access policies that align with industry standards.
