## Data Encryption
|
||||
|
||||
All sensitive data is encrypted at rest and in transit to prevent unauthorized access.
|
||||
|
||||
## Access Controls
|
||||
|
||||
Role-based access controls (RBAC) are implemented to restrict data access based on user roles and responsibilities.
|
||||
|
||||
Also see [Authentication and Authorization](08_concepts.md#authentication-and-authorization) and the [Data Model](08_02_data_model.md#user-roles) sections.
|
||||
|
||||
## Audit Logging
|
||||
|
||||
Comprehensive logging of user activities and system events is maintained for monitoring and auditing purposes. Also see [Error Handling and Logging](08_concepts.md#error-handling-and-logging) section for more details.
|
||||
|
||||
## Vulnerability Management
|
||||
|
||||
Regular security assessments and updates are conducted to identify and mitigate potential vulnerabilities.
|
||||
|
||||
## Compliance
|
||||
|
||||

## Level 2: Security Layers Explanation
|
||||
|
||||
### Frontend Layer
|
||||
|
||||
The Frontend Layer implements secure communication protocols (e.g., HTTPS) to ensure data transmitted between the client and server is encrypted. It also incorporates input validation to prevent common vulnerabilities such as XSS and CSRF attacks.
|
||||
|
||||
### API Layer
|
||||
|
||||
The API Layer enforces authentication and authorization mechanisms to control access to backend services. It validates incoming requests and ensures that only authorized users can access specific resources.
|
||||
|
||||
### Service Layer
|
||||
|
||||
The Service Layer handles business logic while ensuring that data processing adheres to security policies. It also manages session security and implements rate limiting to prevent abuse.
|
||||
|
||||
### Data Access Layer
|
||||
|
||||
The Data Access Layer is responsible for securely interacting with the database. It uses parameterized queries to prevent SQL injection attacks and ensures that data access is logged for auditing purposes.
|
||||
|
||||
### Database System
|
||||
|
||||
The Database System employs encryption at rest and in transit to protect sensitive data. It also implements access controls to restrict database access based on user roles.
|
||||
Data is regularly backed up, and recovery procedures are in place to ensure data integrity in case of failures.
|
||||
|
||||
### Encrypted Data Storage
|
||||
|
||||
All sensitive data stored in the system is encrypted using industry-standard encryption algorithms. This ensures that even if data storage is compromised, the data remains protected and inaccessible to unauthorized users.

# User Interface Design Principles
|
||||
|
||||
<!-- CalMiner aims to provide a comprehensive platform for mining project scenario analysis, enabling stakeholders to make informed decisions based on data-driven insights. -->
|
||||
|
||||
A user-friendly and intuitive user interface (UI) is crucial for the success of the Calminer system. The UI design principles outlined below ensure that users can effectively interact with the system, access necessary features, and derive maximum value from the platform.
|
||||
|
||||
## Key Design Principles
|
||||
|
||||
1. **Clarity**: The UI presents information clearly and concisely, minimizing cognitive load and helping users understand the system's functionality.
|
||||
2. **Consistency**: The UI maintains a consistent look and feel across all components, ensuring users can easily navigate and interact with the system.
|
||||
3. **Customizability**: The UI allows customization for individual settings and preferences, enabling a true multi-tenancy look and feel.
|
||||
4. **Responsiveness**: The UI adapts to different screen sizes and devices, providing an optimal experience for all users.
|
||||
5. **Simplicity**: The design prioritizes simplicity, presenting information clearly and avoiding unnecessary complexity.
|
||||
6. **Feedback**: The UI provides timely feedback to user actions, ensuring users are informed of the results of their interactions.
|
||||
|
||||
## Concepts
|
||||
|
||||
To facilitate the implementation of these design principles, the following concepts are employed in the UI design:
|
||||
|
||||
- **Modular Design**: The UI is structured into modular components, allowing for easy maintenance, updates, and scalability.
|
||||
- **Intuitive Navigation**: Clear navigation paths and menus are provided to help users find features and information quickly.
|
||||
- **Visual Hierarchy**: Important elements are emphasized through size, color, and placement to guide user attention.
|
||||
- **Accessibility**: The UI is designed to be accessible to users with disabilities, following best practices for inclusive design.
|
||||
- **User-Centered Design**: The design process involves user feedback and testing to ensure the UI meets the needs and expectations of its target audience.
|
||||
- **Interactive Elements**: Buttons, forms, and other interactive elements are designed to be easily identifiable and usable.
|
||||
- **Data Visualization**: Charts, graphs, and other visual tools are used to present complex data in an understandable format.
|
||||
|
||||
## Implementation Considerations
|
||||
|
||||
When implementing the UI design principles and concepts, the following considerations should be taken into account:
|
||||
|
||||
- **Performance**: The UI should load quickly and respond promptly to user interactions to ensure a smooth user experience.
|
||||
- **Cross-Browser Compatibility**: The UI should function consistently across different web browsers and platforms.
|
||||
- **Localization**: The UI should support multiple languages and regional settings to accommodate a diverse user base.
|
||||
- **Security**: The UI should incorporate security best practices to protect user data and prevent unauthorized access.
