Crypto-shredding is the method of ‘deleting’ encrypted data by destroying the encryption keys. This method is particularly useful in cloud environments where physical destruction of storage media is not feasible. By deleting the keys used to encrypt the data, the data itself becomes inaccessible and is effectively considered deleted.

Here’s how crypto-shredding works:

Encryption: Data is encrypted using cryptographic keys, which are essential for decrypting the data to make it readable.

Key Management: The keys are managed separately from the data, often in a secure key management system.

Deletion of Keys: When instructed to delete the data, instead of trying to erase the actual data, the encryption keys are deleted.

Data Inaccessibility: Without the keys, the encrypted data cannot be decrypted, rendering it unreadable and unrecoverable.

Compliance: This method helps organizations comply with data protection regulations that require secure deletion of personal data.

Azure Information Protection (AIP) is a cloud-based solution that helps organizations classify and protect documents and emails by applying labels. AIP can be used to protect both data at rest and in transit, making it suitable for securely sharing classified information.

Here’s how AIP secures document sharing:

Classification and Labeling: AIP allows administrators to classify data based on sensitivity and apply labels that carry protection settings.

Protection: It uses encryption, identity, and authorization policies to protect documents and emails.

Access Control: Only authorized users with the right permissions can access protected documents, even if the document is shared outside the organization.

Tracking and Revocation: Administrators can track activities on shared documents and revoke access if necessary.

Integration: AIP integrates with other Microsoft services and applications, ensuring a seamless protection experience across the organization’s data ecosystem.

ISO 27001 & 27002 standards are applicable for cloud security auditing that enables the management of customer data. These standards provide a framework for information security management practices and controls within the context of the organization’s information risk management processes.

ISO 27001: This is an international standard on how to manage information security. It provides requirements for an information security management system (ISMS) and is designed to ensure the selection of adequate and proportionate security controls.

ISO 27002: This standard supplements ISO 27001 by providing a reference set of generic information security controls including best practices in information security.

Auditing and Management: Both standards include guidelines and principles for initiating, implementing, maintaining, and improving information security management within an organization, which is essential for auditing and managing customer data.

Risk Assessment: They emphasize the importance of assessing IT risks as part of the audit process, ensuring that any hidden infrastructure or unused workloads are identified and managed appropriately.

References:ISO 27001 & 27002 standards are recognized globally and are often used as a benchmark for assessing and auditing information security management systems, making them suitable for organizations looking to optimize their cloud inventory and manage customer data securely12.
