Data Masking in Oracle Cloud

To mask Personally Identifiable Information (PII) data in Oracle Cloud, you can use Oracle’s Data Masking and Subsetting feature, which is part of the Oracle Cloud Database Security offering.

Here are the general steps you can follow to mask PII data in Oracle Cloud:

  1. Identify the PII data: First, identify the PII data elements that need to be masked, such as social security numbers, email addresses, or phone numbers.
  2. Create a Data Masking Plan: Define a Data Masking Plan that outlines the rules for masking the identified PII data. The plan should include details on the masking algorithm to be used, the scope of data to be masked, and who can access the masked data.
  3. Apply the Data Masking Plan: Apply the Data Masking Plan to the appropriate tables or columns in your Oracle Cloud Database. This will mask the PII data according to the rules defined in the plan.
  4. Test and Validate the Data Masking: Test the data masking to ensure that it is working as expected and that the masked data is still usable for testing or other purposes.
  5. Monitor and Audit the Data Masking: Monitor and audit the data masking process to ensure that it continues to meet your organization’s data security and compliance requirements.

It’s important to note that data masking is just one aspect of a comprehensive data security and privacy strategy. Organizations should also implement other measures such as access controls, encryption, and monitoring to ensure that sensitive data is protected from unauthorized access or exposure.
