Data integrity is fundamental to the success of attack surface management (ASM). It ensures the accuracy of information used in vulnerability assessments, the reliability of security controls, the effectiveness of incident response, and overall trustworthiness in managing and securing an organization's IT environment.
In practice, data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. In the context of ASM, data integrity ensures that data remains unaltered and trustworthy from creation to storage and processing. Maintaining data integrity is crucial for the proper functioning of systems, applications, and databases. It helps prevent errors, corruption, and unauthorized modifications that could compromise the reliability and usability of the data.
Maintaining data integrity is crucial for the effective functioning of IT systems and ensuring the security of information. Here are five fundamental principles to keep in mind as you build or augment your attack surface management strategy:
1. Data accuracy:
- Ensure that data is accurate and reflects the true state of the information it represents.
- Implement validation checks to verify the correctness of data at entry points.
- Regularly audit and reconcile data to identify and correct discrepancies.
2. Data consistency:
- Ensure that data remains consistent across different databases, systems, and applications.
- Implement standardized data formats and conventions to promote consistency.
- Use transactions and atomic operations to maintain consistency during data updates.
3. Reliability:
- Establish mechanisms to ensure the reliability of data throughout its lifecycle.
- Implement proper backup and recovery procedures to protect against data loss.
- Monitor and detect anomalies or errors that may compromise data reliability.
4. Integrity Controls:
- Implement cryptographic hashes or checksums to detect and prevent unauthorized modifications to data.
- Use access controls and permissions to restrict who can modify or delete data.
- Employ digital signatures to verify the authenticity and integrity of data.
5. Auditing and Monitoring:
- Implement robust auditing mechanisms to track changes to data and access events.
- Regularly review audit logs to identify any suspicious or unauthorized activities.
- Use intrusion detection systems and security information and event management (SIEM) tools to monitor for potential threats to data integrity.
By focusing on these fundamentals, you can establish a strong foundation for maintaining data integrity within attack surface management. This foundation is essential for building secure and reliable systems, preventing data corruption, and ensuring that information remains trustworthy throughout its lifecycle.
Supporting data integrity with data access
Legacy data permissions practices and technology make it impossible to audit data permissions based on a business’s sensitive information and where it lives, potentially compromising your data integrity efforts.
Limiting access to sensitive data starts by understanding what sensitive data your organization has. Data discovery and classification set a foundation that ensures data access is limited by its type and sensitivity and fulfills data integrity requirements.
The Cavelo platform continuously scans cloud applications, cloud hosted servers, and on-premises servers and desktops to identify, classify, track, protect, and report on sensitive data, including PII. It automates data discovery and classification, producing an up-to-date and accurate data inventory that supports compliance, insurance, and regulatory preparedness.
