Cloud access control refers to the policies, procedures, and technologies that enable authorised access to cloud-based resources while mitigating security risks and ensuring compliance with data protection regulations.
Effective cloud access control is critical for preventing unauthorised access, data breaches, and potential compliance violations. Organisations can confidently embrace the benefits of cloud computing while protecting their digital assets by putting in place stringent access controls.
Continue reading to learn more about cloud access control, its importance, and the 5 models used to accomplish it.
What is Cloud Access Control?
Cloud access control is the process of managing and restricting access to cloud-based systems and data. It includes authentication, authorisation, and auditing processes to ensure that only authorised individuals or entities have access to specific cloud resources.
At its core, this process operates by verifying users’ identities, determining their level of access based on predefined permissions, and monitoring their activities to detect and prevent unauthorized actions. This level of control over access privileges is critical for ensuring the integrity and confidentiality of sensitive data stored in the cloud.
Before we get into the the main topics of our discussion, you might want to look into other cloud topics. Cloud provisioning is one of these important aspects. Our article, “Cloud Provisioning: What It Is and How It Can Benefit Businesses“, will help you learn more about the subject.
Why is Cloud Access Control Important?
This process is vital for various reasons. Firstly, it enhances security by safeguarding against unauthorised access and potential data breaches through the use of digitally encrypted credentials and integration with other security systems.
Secondly, it ensures regulatory compliance by controlling access to sensitive data, helping businesses avoid penalties associated with non-compliance.
Thirdly, cloud access control systems promote operational efficiency by providing quick resource access, boosting employee productivity, and enabling remote work capabilities, especially relevant during events like the COVID-19 pandemic.
Additionally, these systems offer scalability, allowing for easy expansion to accommodate growing businesses and changing needs.
Furthermore, they enable remote management, allowing administrators to adjust access permissions from anywhere, respond promptly to incidents, and benefit from automatic updates and patches, ensuring up-to-date security measures.
Moreover, cloud access control systems offer seamless integrations with other software, facilitating comprehensive monitoring from a single interface, while also delivering cost savings compared to on-premises solutions, which require substantial upfront investment and ongoing maintenance expenses.
How Does Cloud Access Control Work?
Cloud access control is a system that allows companies to regulate and monitor permissions to access their business data in cloud environments.
It helps businesses gain granular control over corporate data and user behaviour, ensuring there is no data breach or data loss by users. Access control in cloud security involves formulating various policies to restrict access to specific IP addresses, browsers, devices, and during certain time shifts.
The role of access control in cloud security is to manage and control who has permission to access resources in a cloud environment.
It is an important component of security frameworks because it helps prevent unauthorized access to sensitive information. Businesses can reduce their risk of data breaches by defining who has access to specific data and applications.
Cloud access control systems protect against unauthorised access, reducing the risk of theft or data breaches.
They assist businesses in meeting industry-specific data access regulations, increasing operational efficiency by providing quick and easy access to necessary resources, and ensuring scalability as the business grows.
What are the 5 access control models?
Access control models are used to determine who has access to what resources. There are five types of access control models: discretionary access control, mandatory access control, role-based access control, rule-based access control, and attribute based access control. Here are the explanations for each.
1. Discretionary Access Control (DAC)
DAC is a flexible model that allows resource owners to grant permissions to users. It is commonly used in Windows, Macintosh, and most Linux operating systems. However, it can be challenging to administer due to its decentralised approach.
2. Mandatory Access Control (MAC)
MAC is a strict model where access decisions are made by the system administrator. It is commonly used by organizations with high-level security needs, such as government agencies and financial institutions.
3. Role-Based Access Control (RBAC)
RBAC is an automated approach that assigns users roles based on their job titles or positions. Users are then granted access based on their assigned role. It is a popular choice for organisations that need to manage access for a large number of users.
4. Rule-Based Access Control (RuBAC)
RuBAC uses a set of rules to determine access permissions. These rules can be based on factors such as time, frequency of use, or other variables. It is often used in conjunction with other access control models to provide additional layers of security.
5. Attribute-Based Access Control (ABAC)
ABAC is a granular model that uses attributes to make access decisions. These attributes can pertain to the subject, object, or action attempted. It allows for fine-grained control over access privileges and can be used as a foundation for other access control models.
These models can be used individually or in combination to provide a comprehensive access control solution that meets the specific needs of an organisation.

Cloud-based Security vs. Traditional
Security Cloud-based security provides scalability and flexibility, allowing organisations to quickly adapt to changing needs and environments. Traditional security measures, on the other hand, may be more rigid and time-consuming to maintain and update.
The Kisi blog outlines several disadvantages of legacy access control over a cloud-based physical access control system, including:
- Higher upfront costs (e.g., purchasing local servers and other hardware).
- Proprietary legacy systems make it difficult to switch to a different security vendor.
- Centralised controllers are typically limited to a specific number of doors.
- They require the presence of an on-site specialist who can react to an issue as it arises.
A cloud-based physical access control system allows you to convert your capital costs into ongoing operating costs.
Increased scalability and flexibility are made possible by the low cost of purchasing servers and the wiring needed to connect each component of access control. You can also add an infinite number of doors and users to the system.
Lastly, unlike traditional access control, which necessitates a physical interface for communication, IP access control can be easily integrated with building management systems, video surveillance, and fire alarms.
Ultimately, the choice between cloud-based and traditional security depends on the unique requirements and priorities of each organisation.
Conclusion
Finally, maintaining the security of cloud-based resources and data requires efficient cloud access control. Organisations may modify their security plans to suit their unique requirements by being aware of the subtle differences between various access control models and procedures.
A strong cloud access control system is essential for maintaining data security, regulatory compliance, and authorised access to cloud-based resources as the world’s reliance on cloud computing grows.
