Authorization is one of the fundamental aspects of any typical CIAM integration and within that realm, two key concepts often discussed are Access Control and Consent. While these terms are sometimes used interchangeably, they serve distinct functions and the differences between the two are important to understand.
My name’s Peter Fernandez, and in this article, I’m going to take you on an exploration of Access Control and Consent, their roles in the authorization process, and how delivering both within a CIAM integration can offer significant benefits to SaaS vendors and end users alike.
Before diving into the specifics, however, it’s important to clearly define both concepts from the perspective of a CIAM Authorization context. As data privacy becomes increasingly important, SaaS solutions that leverage Authorization for both Access Control and Consent will be better positioned to foster trust, ensure compliance, and deliver a personalized, secure experience for their customers.
What is Access Control?
Access control is the mechanism by which access to resources is managed and controlled, and under what conditions. In the context of CIAM, access control is about ensuring that access is only granted to the digital assets and data with which someone (or something) is authorized to interact. This is achieved by evaluating credentials, roles, permissions, and other factors that determine whether a particular individual should be granted access to a specific resource:
- Mandatory Access Control (MAC): is the most common form of Access Control, where access decisions are made based on predefined policies over which there is no control outside of an administrative context.
- Discretionary Access Control (DAC): is where access is granted based on the owner’s discretion — meaning that someone or something, typically a user, can give others access to their resources.
Less common than its “Mandatory” counterpart, Discretionary Access Control typically plays a useful role in delegation scenarios and the like.
Access control ensures that the right access is provided to the right resources at the right time — thus minimizing the risk of unauthorized access. Here are a few of the popular access control models often employed:
- Role-Based Access Control (RBAC): Access is based on the role something or someone holds within an organization. For instance, a user can be assigned one or more roles, and those roles determine what resources they can access.
- Attribute-Based Access Control (ABAC): Access is determined based on a set of attributes (e.g., location, time of access, date or day of access, etc.)
- Relationship-Based Access Control (ReBac):Access is determined based on the relationships between entities — e.g., between users in an organization (manager and subordinate, etc), or across the groups to which someone or something might belong.
All of the above can be employed in some combination, and what that combination looks like largely depends on the features and the functionality your B2C/B2B SaaS application might provide. Read more about access control in my article entitled
What is Consent?
Consent, in the context of CIAM, refers to the explicit permission granted by a user to access and process their (personal) data. Consent is user-specific, and it is a critical element of privacy compliance; especially in light of regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) — under which organizations are required to obtain and document a user’s consent before collecting, storing, or processing their personal information.
Consent focuses on user autonomy, providing individuals with the ability to control what data they share, how it is used, and for what purposes. It also ensures that users are aware of the privacy implications of their actions and interactions with digital platforms. You can find out more about consent in my article entitled
Access Control and Consent in the Authorization Process
Access Control
Access control plays a pivotal role in the authorization process because it helps define which resources something or someone is permitted to access.
Authorization typically occurs after Authentication, and whilst Authentication is typically performed periodically, Authorization is usually performed each time access is requested to something that is access-controlled.
Access control is the mechanism that enforces the rules about what an authenticated entity — i.e. a person or an automated service — can or cannot do within a system. Without access control, something or someone may gain access to sensitive or restricted data, potentially jeopardizing the security of a system (particularly in a B2B SaaS scenario).
Access control is typically implemented via a combination of policy and the leveraging of one or more Access Control mechanisms — i.e. RBAC, ABAC, ReBAC, etc. Evaluation is then performed as part of the authorization process to determine whether the necessary permission(s) have been granted to perform specific actions (such as accessing sensitive data, modifying personal information, or interacting with particular features within an application).
For example, consider an online banking system. Once a user has logged in, access control mechanisms ensure that the user can only access their own account information and perform actions such as checking account balances or transferring funds. They would not have access to other users’ accounts or administrative controls unless explicitly authorized.
Consent
Consent, on the other hand, is more concerned with the user’s permission to process their data and interact with various services in a way that aligns with their privacy preferences. While access control addresses the question of who can access what, consent addresses the question of what (personal) data can be collected, used, and shared.
For instance, when a user signs up for a B2C or B2B SaaS solution, they are typically asked to provide consent for the collection and processing of certain personal data — such as their name, email address, location, etc. The user must be fully informed about the nature of the data being collected, how it will be used, and with whom it may be shared. Furthermore, they have the right to withdraw this consent at any time, ensuring compliance with privacy laws and regulations.
Combining Access Control and Consent in a CIAM Context
The combination of Access Control and Consent ensures that not only is authorized access to specific resources ensured but also that user personal data is being handled in a lawful and transparent manner. A comprehensive CIAM implementation integrates both Access Control and Consent management, providing streamlined authorization while ensuring compliance with privacy laws.
Let’s take a closer look at the benefits of using both Access Control and Consent as part of a CIAM solution.
Enhancing User Security
Access Control ensures that only authorized users can access certain resources, thereby enhancing the security of the system. By coupling, say, RBAC with Consent — potentially incorporating MFA for step-up authentication — organizations can ensure that users are aware of the privacy implications of their actions. This dual-layered approach strengthens both security and privacy simultaneously, building trust between the organization and its customers.
Granular Access Control
Granular access controls are possible based on various factors, such as role, location and device type, together with the specific action(s) being performed. Incorporating ReBAC — where access decisions are based on relationships — makes this type of fine-grained access control manageable, ensuring sensitive information is kept secure and that only data relevant to the specific need(s) is exposed.
Compliance with Privacy Regulations
Compliance with privacy regulations like GDPR, CCPA, and others is essential for businesses operating in the modern digital landscape. Consent management ensures that organizations can collect, process, and store personal data in compliance with these regulations. By obtaining explicit user consent and providing users with the ability to manage their preferences, businesses can reduce the risk of non-compliance.
Additionally, CIAMintegrations that track and log consent transactions, make it easier to demonstrate compliance during audits or investigations. This proactive approach to consent ensures that organizations are transparent with users about how their data is being used, fostering trust and improving the user experience.
Enhancing User Experience and Trust
A key advantage of incorporating both Access Control and Consent management within a CIAM integration is that it creates a more personalized and secure user experience. Users can easily access the resources they need, while also maintaining control over their personal data. This transparency and control increase user trust, which is a critical factor in retaining customers in today’s competitive digital economy.
Moreover, by offering users the ability to manage their data preferences (such as opting in or out of specific data collection practices), organizations can offer a more tailored experience while respecting user autonomy. This ultimately leads to greater customer satisfaction and loyalty.
Streamlining Administration and Reducing Risk
CIAM integrations that seamlessly combine both Access Control and Consent management allow organizations to streamline administration by centralizing user identity and access policies. This centralization reduces the complexity of managing user permissions across multiple applications and systems.
Further, this approach reduces the risk of data breaches, unauthorized access, and non-compliance with privacy laws. By enforcing strict access controls and obtaining user consent for data collection, organizations mitigate the risks associated with poor access management and data misuse.
