How does AVEVA Historian ensure data integrity and security?

1. Data Integrity Through High-Quality Data Collection

Data from a variety of sources may be gathered and stored with great quality using AVEVA Historian. The procedure used to acquire the data sets the stage for its integrity. To record real-time data from many sensors, control systems, and other data sources with the least amount of loss, the historian uses cutting-edge data acquisition methods.

• Real-Time Data Capture: High-speed data gathering is supported by AVEVA  Historian, ensuring minimal delay in data recording. The capacity to process data in real-time is essential to preserving its relevance and accuracy.
• Data Compression and Optimization: Data compression methods are used by AVEVA Historian to efficiently manage enormous amounts of data. These techniques lessen the need for storing space while maintaining the accuracy and consistency of the data. Effective management of historical data is facilitated by compression, which permits long-term storage without sacrificing data integrity.
• Redundancy and Failover Mechanisms: Redundancy and failover features are included into AVEVA Historian to protect against data loss caused by system failures. Even in the case of software or hardware malfunctions, these protections guarantee that data collecting will continue unhindered. Backup plans and redundant systems aid in preserving data integrity in these kinds of situations.

2. Robust Security Measures

Since industrial data is sensitive, data security is a vital component of AVEVA Historian. The historian uses many levels of security to guard against breaches, manipulation, and unwanted access to data:

• User Authentication and Authorization: Strict user authentication procedures are used by AVEVA Historian to guarantee that only authorised users are able to access the system. Based on user roles, role-based access control, or RBAC, is used to govern permissions and limit access to sensitive information. This stops unauthorised individuals from accessing or changing private data.
• Data Encryption: Data encryption methods are used by AVEVA Historian to safeguard data while it is in transit and at rest. Data encryption makes sure that information is safe and unreadable even in the event that it is accessed without permission or intercepted during transit. When it comes to safeguarding data during transmission across networks or remote access, this is especially crucial.
• Audit Trails and Monitoring: All user actions and system modifications are meticulously recorded in the audit trails kept by AVEVA Historian. A detailed history of system access, activities taken, and when they were done is available in these logs. Frequent review and monitoring of these audit trails aid in quickly detecting and addressing any unauthorised or questionable activity.
• Compliance with Industry Standards: AVEVA (Wonderware) Historian complies with industry guidelines and rules on data security. This involves adhering to guidelines for information security management systems (ISMS) provided by ISO/IEC 27001 and other standards. Following these guidelines guarantees that AVEVA Historian satisfies strict security requirements and offers a dependable data management solution.

3. Data Integrity Verification

Data integrity requires not just shielding it from outside dangers but also periodically confirming its accuracy and consistency. A number of methods are included into AVEVA Historian to ensure and preserve data integrity:

• Data Validation and Error Checking: To find and fix any inconsistencies or abnormalities in the data, the historian regularly validates and verifies the data. This involves verifying the correctness, consistency, and completeness of the data.
• Historical Data Verification: Reliability and integrity of long-term data are maintained by regular historical data verification. Validation procedures are employed by AVEVA Historian to identify and resolve possible problems with the integrity of historical data.
• Backup and Recovery Procedures: Maintaining data integrity and guaranteeing data recovery in the event of unintentional deletion or corruption need routine backups. With the help of automatic backup processes and data recovery tools, AVEVA Historian makes sure that data is always available and undamaged, even in the worst of circumstances.

4. Scalability and Flexibility

The scalability and adaptability of AVEVA Historian to evolving needs is another factor that supports data security and integrity. The historian is built to manage growing data volumes and changing security requirements.

• Scalable Architecture: Because of its scalable architecture, AVEVA Historian may expand to meet the demands of the company. In the event of growing data volumes or data sources, the historian may scale to meet these needs without compromising data integrity.
• Flexible Configuration Options: The historian offers customisable configuration options so that data management procedures and security settings may be adjusted to meet the needs of individual organisations. Because of its adaptability, the system may be adapted to suit changing security risks and requirements for data management.

Conclusion

A testimony to the significance of data security and integrity in industrial data management is AVEVA Historian. Industrial data is kept accurate, safe, and dependable by AVEVA Historian because to its scalable design, strong security mechanisms, and meticulous data integrity verification procedures. AVEVA Historian assists organisations in upholding operational excellence and making defensible judgements by employing these cutting-edge features and procedures.
