Provenance is the verified origin and custody history of a file, image, build, or device artifact. In security work, it answers practical questions: Where did this come from? Who created it? Has it been modified, repackaged, or signed by a trusted party?
Provenance matters because attackers often hide malware inside trusted-looking software, disk images, firmware, or build outputs. A file can be authentic in format but untrusted in origin, which is why defenders check hashes, signatures, SBOMs, release metadata, and chain-of-custody records. In hardware projects, provenance is especially important for FPGA bitstreams, imported peripherals, and archived media: if the source is unclear, the artifact should be treated as suspicious until verified and isolated. Strong provenance helps distinguish a genuine reconstruction from a tampered one and reduces the risk of supply-chain compromise.
