FakeTDL (v1.0) is a fictional data format intended to be used to illustrate the data format and cybersecurity data filtering issues that arise in military Tactical Data Link (TDL) data.
The specifications of real TDL data formats are all non-public, as are the specifications of the data transformation and routing rules. FakeTDL defines TDL-like messages that allow illustration of the kinds of data format and data transformation that are required for TDL data, without the need to disclose any non-public specifications.
FakeTDL facilitates training and study of:
-
Data Format Description Language (DFDL) descriptions of TDL data formats
-
Schematron rules for advanced validation of TDL data
-
XSLT to block specific kinds of messages
-
XSLT to redact (overwrite), modify numeric precision, or remove optional fields
-
Basic Geo-location filtering (removing messages that are about entities outside the area of interest, or modifying locations of messages (or blocking messages) that are within exclusion regions)
-
Advanced Filtering Scenarios including Inter-Message Correlation and Inter-Source Corroboration
The FakeTDL messages and fields are described in the FakeTDL Specification.
