Using managed data identifiers in Amazon Macie
To discover sensitive data, Amazon Macie uses a combination of criteria and techniques, including machine learning and pattern matching, to analyze data that you specify. These criteria and techniques, referred to as managed data identifiers, are designed to detect a large and growing list of sensitive data types for many countries and regions, including multiple types of personally identifiable information (PII), personal health information (PHI), and financial data. Macie automatically uses these identifiers each time it analyzes data in an S3 bucket as part of a sensitive data discovery job that you create and run.
The topics in this section list and describe the different types of sensitive data that Macie can detect and relevant requirements for detecting that data.
Topics
For information about the types of data that Macie can analyze, see Supported file and storage formats.
Keyword requirements
To detect certain types of sensitive data, Macie requires a keyword to be in proximity of the data. If this is the case for a particular type of data, a subsequent topic in this section indicates the keyword requirements for that data.
If a keyword has to be in proximity of a particular type of data, the proximity requirements vary based on file type or storage format.
- Unstructured data
-
For Adobe Portable Document Format files, Microsoft Word documents, and non-binary text files other than CSV and TSV files, a keyword typically has to be within 30 characters (inclusively) of the data. This includes any structured data, such as tables, in these types of files.
- Structured data
-
For columnar and record-based data, a keyword has to be part of the same value or the name of the column or field that stores a value. This is true for Apache Avro object containers, Apache Parquet files, Microsoft Excel workbooks, CSV files, and TSV files.
For example, if a field contains both SSN and a nine-digit number that uses the syntax of a US Social Security number (SSN), Macie can detect the SSN in the field. Similarly, if a column name contains SSN, Macie can detect each SSN in the column. Macie treats the values in that column as being within proximity of the keyword SSN.
Keywords aren’t case sensitive. In addition, if a keyword contains a space, Macie automatically matches keyword variations that don’t contain the space, or contain an underscore (_) or a hyphen (-) instead of the space.
