| Name | ID | Definition | Synonyms |
|---|---|---|---|
| Content Validation | D3-CV | Verify and validate contents complies with policy | |
| - File Format Verification | D3-FFV | Verifying that a file conforms to its expected format specifications | |
| - File Metadata Consistency Validation | D3-FMCV | The process of validating the consistency between a file's metadata and its actual content, ensuring that elements like declared lengths, pointers, and checksums accurately describe the file's content. | |
| - File Metadata Value Verification | D3-FMVV | The process of checking specific static values within a file, such as file signatures or magic numbers, to ensure they match the expected values defined by the file format specification. | |
| - File Content Decompression Checking | D3-FCDC | Checking if compressed or encoded data sections can be successfully decompressed or decoded. Can follow with further analysis with semantic knowledge | |
| - File Internal Structure Verification | D3-FISV | The process of checking specific static values within a file, such as file signatures or magic numbers, to ensure they match the expected values defined by the file format specification. | |
| - File Magic Byte Verification | D3-FMBV | Utilizing the magic number to verify the file |
