## Set Up Data Access Controls in an SAP Analytics Cloud Model Dimension Business Scenario: Since The Mock Company uses an import data model for their operational income for planning, you have been asked to set up data access controls for the Entity dimension so that teams are granted either Read or Write access to the data, depending on their team requirements. Task Flow: In this practice exercise, you will: [...] SAP Analytics Cloud model open to the Entity dimension where DAC has been enabled Note Even with Data Access Control applied to a dimension, master data is still be visible to users, as restrictions created using Data Access Control apply only to transaction data. If a user is assigned the BI Admin role, or is the model owner, then that user always has full access to the model, regardless of the DAC settings applied to that model. ### Version Security in Planning-Enabled Models [...] To enable dimension security, switch on Data Access Control (DAC) for each dimension in the Model Preferences. In the example below, you can see that DAC has been enabled for the Entity dimension. SAP Analytics Cloud model preferences open to the Access and Privacy section. Data Access Control for the Entity dimension has been enabled. ### Enable Data Access Control from the Dimension Table
For data access control to be effective, authentication and authorization needs to be applied consistently across your entire environment — both on premises and in the cloud. ## Data access control models There are four main models for applying data access control: [...] With the DAC model, the end user — the person who creates the file or folder, for example — has complete discretion for setting the permission privileges, as well as transferring permissions to other users. This model has some inherent security issues, such as vulnerabilities to Trojan horses and other malware attacks. [...] Discretionary access control (DAC): The least restrictive data access control model, DAC relies on the owner or administrator of the resource or to decide who has access permission. This model is decentralized, giving users the ability to share access with others, and making it difficult to oversee who is accessing your company’s sensitive information.
For any organization, cloud data access security is nothing without a mechanism to protect and strengthen it, and this is known as cloud data access governance. It involves the use of automated tools to implement access controls according to the ‘least privilege’ policy, since IT is rapidly evolving and more organizations are switching to the cloud for more flexibility and smooth operations. [...] The enterprise cloud is a structural model in which organizations gain access to virtual resources from a cloud services provider as per a pay-per-use model. These resources include: Servers CPU cores Data storage Network infrastructure Virtualization This allows businesses to cut down on their operational costs, while also optimizing business operations and enhancing network security. There are two different types of enterprise cloud data access: public and private cloud. [...] Satori helps streamline access to data stored in cloud data warehouses and databases. It enables simple access controls without the need of intensive data engineering resources, fine-grained access, RBAC and ABAC.

The Policy-Based Access Control (PBAC) method controls access based on pre-set and customizable policies. These policies consider data and user attributes, actions, and environmental factors. Its detailed and flexible control makes PBAC a popular choice for scaling access controls across cloud environments. ## Implementing Data Access Control [...] Data access control is a protective strategy that manages who can access, modify, or view specific data. It's an integral part of cybersecurity and data management, maintaining the privacy, confidentiality, integrity, and availability of sensitive information through restrictions and permissions. [...] Conversely, Discretionary Access Control (DAC) allows data owners to control data access. Despite its flexibility, this model risks data exposure to security threats if owners are not cautious with permissions. Role-Based Access Control
Access control models: The main models are DAC (owner-controlled), MAC (label-based), RBAC (role-based), and ABAC (attribute/policy-based).
Access control in cloud security is about managing and controlling who has permission to access resources in a cloud environment. It's an essential component of security frameworks, helping prevent unauthorized access to sensitive information. By defining who can access specific data and applications, we're reshaping security and reducing the risk of data breaches. ## The Importance of Access Control for Businesses [...] 1. Enhanced Security: Access control systems protect against unauthorized access, reducing the risk of theft or data breaches. 2. Regulatory Compliance: They help meet industry-specific regulations regarding data and physical access. 3. Operational Efficiency: Quick and easy access to needed resources can boost employee productivity. 4. Scalability: As your business grows, access control systems can easily be expanded to cover new users and locations. [...] Access control is crucial for businesses for various reasons. First, it protects confidential information from unauthorized access, ensuring only those with the necessary permissions can access specific resources. This protection extends to both digital assets such as databases and physical assets like office buildings via our visitor management solutions.
