18th October, 2023


As an IT manager, ensuring the security of your organization's sensitive data and resources is paramount. Establishing robust access control measures to enhance your organization's security framework is crucial.

By gaining a comprehensive understanding of access control and its implications, you will be better equipped to make informed decisions and implement effective strategies to protect your organization's valuable assets.

Picture this: You have a network of sensitive data, confidential documents, and high-security zones. How do you ensure that only authorized personnel gain entry? This is where access control systems come into play. At their core, these systems establish a security framework that determines who can access specific resources within your organization. 

But it's not just about granting or denying access; it's about implementing foolproof authentication and authorization rules that make your data impenetrable.

Authentication verifies users' identity, ensuring that only authorized individuals gain access to your organization's protected areas. Usernames, passwords, PINs, security tokens, and even cutting-edge biometric scans form the foundation of authentication. By implementing strong authentication measures, you create a highly secure defense system that allows entry into your organization's protected areas exclusively for authorized individuals.

Now, let's talk about authorization. Once your users have been successfully authenticated, they need appropriate privileges and permissions to access specific resources. Here, access control systems come into play, employing the power of authorization rules. These rules define who can access what based on their roles, responsibilities, and clearance levels. By finely tuning these rules, you empower your IT team to grant granular access privileges, minimizing the risk of data breaches and ensuring regulatory compliance.

But wait, there's more! Implementing an access control system isn't a one-size-fits-all affair. Your organization's unique requirements demand a tailored approach. 

As an IT manager, you need to consider factors such as the level of ownership you desire over the system and how to determine access privileges for different employee groups. Fortunately, a plethora of access control models exist, each offering distinct benefits. 

Whether it's role-based access control, attribute-based access control, or even the latest advancements in dynamic authorization, you have an array of options at your disposal.

Let’s take a look at the different types of access control and its specifics. 

4 Major Types of Access Control

Several types of access control mechanisms are commonly used to ensure authorized access and protect sensitive resources. These types can be categorized as follows:

1. Discretionary Access Control (DAC)

Among the various access control mechanisms available, one approach that stands out is discretionary access control (DAC). Unlike other systems, DAC places more control in the hands of leadership, allowing your IT team to determine resource access based on individual permissions, even if your IT admin has established a hierarchy of files with predefined access levels. This unique feature sets DAC apart from other access control systems.

DAC offers the advantage of granting access to resources based on the right credentials. By empowering leadership to define who can access specific data or systems, DAC enables a fine-grained level of control and ensures that only authorized personnel gain entry. This flexibility allows you to align access privileges with specific roles and responsibilities, ensuring employees have the access needed to perform their tasks effectively.

However, it is important to note that DAC also introduces certain challenges that require careful oversight. Since the responsibility for managing permissions lies with end-users, there is a need for constant monitoring and supervision to prevent unauthorized access or unintentional breaches. This heightened level of involvement in managing access rights can potentially create gaps or oversights if not diligently addressed.

While other access control models, such as mandatory access control (MAC), offer a rigid and low-effort approach to security, DAC provides a more dynamic and high-effort solution. By allowing leadership to determine and adapt access levels as needed, DAC offers greater flexibility in aligning security measures with an organization's evolving requirements. This adaptability is especially beneficial in environments where roles and responsibilities change frequently or a more collaborative approach to data access is preferred.

2. Role-Based Access Control (RBAC)

As an IT manager, you understand the criticality of efficient access management and robust security measures. One solution that perfectly aligns with your needs is role-based access control (RBAC). RBAC enables you to assign network access based on predefined user roles, providing a structured and streamlined approach to access control.

RBAC allows your team to categorize employees into roles such as managers, contractors, and department heads. By doing so, your team can ensure that permissions align with their job titles and responsibilities. This eliminates the need for constant oversight, enabling your team to focus on critical tasks while maintaining peace of mind.

RBAC doesn't impose rigid access privileges upon you. On the contrary, it offers the flexibility to customize profiles to meet your organization's unique needs. You have the ability to tailor access rights and exceptions as required, striking the perfect balance between control and adaptability.

For small and medium-sized businesses, RBAC brings added advantages. It provides the desired level of control without burdening you with excessive administrative tasks. Managing access at the role level can significantly reduce the administrative burden, improving operational efficiency and freeing up time for more strategic initiatives.

Moreover, since security is a top concern for you, and by implementing RBAC, you can ensure that only authorized personnel have access to sensitive data and resources. This minimizes the risk of security breaches, as unnecessary privileges are reduced or eliminated.

In addition, RBAC also simplifies the employee onboarding and offboarding processes. When new hires join your organization, assigning them role-based profiles guarantees they have access from day one. 

Similarly, when employees leave or change roles, their access rights can be easily adjusted or revoked. This capability eliminates potential security gaps and enhances the overall security posture of your organization.

3. Attribute-Based Access Control

The ever-evolving threat landscape and the growing need for more nuanced control have given rise to a more advanced approach: Attribute-Based Access Control (ABAC). ABAC introduces a complex yet powerful strategy that applies a multitude of attributes to users and resources, enabling your IT admin to make access decisions based on contextual factors and dynamic risk levels.

At the core of ABAC is the concept of attributes. Users are granted access only to resources that possess corresponding attributes. These attributes encompass a wide range of factors, providing rich context and specificity to access control decisions. From user demographics like job title or security clearance to resource properties such as file type or creation date, and even environmental characteristics like access location or time, ABAC takes into account a diverse array of attributes.

The strength of ABAC lies in its granular approach, offering unparalleled flexibility for determining access rights. This allows access control policies to adapt to the unique requirements of each situation, ensuring that individuals have precisely the access they need when they need it. 

Instead of relying solely on predefined roles, ABAC empowers admins to consider a broader set of attributes that accurately capture the context and requirements of access requests.

Implementing ABAC requires thoughtful planning and consideration. Your IT admin must define the relevant attributes and establish their relationships with users and resources. 

Integrating ABAC capabilities into your existing systems or applications may necessitate technical adjustments and coordination. However, the investment in ABAC is undoubtedly worthwhile, as it provides a level of access control sophistication that aligns with the demands of modern IT environments.

4. Policy-Based Access Control

Policy-based access control (PBAC) is an advanced access control mechanism that is specifically designed to cater to your needs. It evaluates access rights and entitlements and provides a flexible framework for adjusting them in accordance with new corporate policies. This dynamic nature of PBAC makes it an invaluable tool for constantly evolving organizations.

Unlike other access control models, PBAC places a strong emphasis on policy enforcement. As organizations undergo changes, they often develop new policies to ensure that access rights remain consistent, appropriate, and secure. 

PBAC leverages these policies to enforce IGA solutions about what actions to take and how to enforce access. This proactive approach ensures that access management aligns with the evolving needs and objectives of the organization.

One notable distinction between PBAC and ABAC lies in their respective focuses. While ABAC primarily relies on attributes to determine access, PBAC takes a policy-driven approach. PBAC empowers you to define policies guiding the IGA solution enforcing access controls. This policy-centric design enables a more proactive and efficient access management process.

Implementing PBAC provides significant benefits. It offers granular security with precise access control based on roles and responsibilities, minimizing unauthorized access. PBAC is reactive to policy changes, ensuring up-to-date access rights. It simplifies compliance management, enforcing controls that adhere to regulations and standards. 

You can easily review and audit access controls, improving ongoing security. PBAC is standards-driven, ensuring compatibility and easy integration into existing infrastructure.

Flawed access control can have devastating consequences, as unauthorized individuals can view, modify, or delete sensitive content, perform unauthorized functions, or even gain control over site administration.
