| Step | Action | IEC Reference | Rationale | |------|--------|---------------|-----------| | | Identify the software artefact, target audience, and applicable licences. | IEC 61355 (document classification) | Ensures that the correct handling class (e.g., “Public Release”) is applied. | | 2. Security Planning | Perform a threat analysis (e.g., ISO/IEC 27001‑aligned) focused on P2P vectors. | IEC 62443 | Determines required security zones, encryption, and access controls. | | 3. Integrity Assurance | Sign the release package (code signing) and embed the public‑key fingerprint in the .torrent file. | IEC 62304 (verification) | Guarantees that only authentic code can be installed. | | 4. Distribution Design | Set up a trusted tracker (or use a private DHT) and enforce an allow‑list of authorised peers. | IEC 62443 (network segregation) | Limits exposure to malicious peers. | | 5. Documentation | Create a release note that includes: IEC classification, version, checksum, licence, and legal disclaimer. | IEC 61355 & IEC 62304 | Provides traceability and auditability. | | 6. Post‑Distribution Monitoring | Log swarm statistics (peer count, download success rate) and correlate with incident‑response logs. | IEC 62443 (monitoring) | Detects abnormal activity such as injection of rogue pieces. | | 7. Archival | Store the final .torrent file, its info‑hash, and the associated signed binaries in a secure repository for the period required by IEC‑mandated record‑keeping (often 5–10 years). | IEC 62304 (configuration management) | Guarantees that the exact distributed artefact can be reconstructed if needed. |

: Torrent sites are notorious hubs for malware. Downloading unverified files can expose your professional workstation—and your company’s entire network—to ransomware or data theft. Seeding Dangers
