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.

AWS IAM Roles: AWS Identity and Access Management (IAM) roles allow for permissions to be assigned to AWS resources without the use of static credentials. Roles provide temporary credentials that are automatically rotated.

Service Role: The ‘get-pics’ service role created by Rebecca includes a permission policy for read-only access to the S3 bucket and a trust policy that allows the EC2 instance to assume the role.

Temporary Credentials: When the application runs on the EC2 instance, it uses the temporary credentials provided by the role to access the S3 bucket. These credentials are dynamically provided and do not require developer management.

Developer and Admin Roles: Since the EC2 instance has the necessary permissions through the service role, the developer does not need to manage credentials. Similarly, the admin does not need to grant explicit permission to the developer because the permissions are already encapsulated within the role.

Security Best Practices: This approach adheres to AWS security best practices by avoiding the sharing of static credentials and minimizing the need for manual credential management.
