PROFILE
Hanspeterson33
Over six months, contributed to the cisagov/icsnpp-c1222 repository by building and enhancing protocol analysis and packet generation features for the C12.22 protocol. Developed centralized and service-level logging in Zeek to improve observability, auditing, and incident response, while refactoring code for maintainability and clarity. Implemented robust packet generation and testing tools using Python and Scapy, enabling simulation and validation of protocol operations in CI pipelines. Addressed security and reliability by refining packet schemas and fixing generation bugs. Leveraged skills in Zeek scripting, network protocol analysis, and Python scripting to deliver features that support monitoring, compliance, and secure protocol workflows.

Mar 1, 2025March 2025 – cisagov/icsnpp-c1222: Delivered enhanced observability and auditability for C1222 protocol interactions. Implemented trace_service_log, wait service logging, and (de)registration logging, plus a refactor of epsemControl logging to produce clearer, human-readable outputs. These changes improve monitoring, auditing, and debugging, reducing mean time to detect and resolve issues.

Feb 1, 2025February 2025: Delivered comprehensive, centralized logging for the C1222 protocol services in cisagov/icsnpp-c1222, enabling detailed request/response capture across Logon, Security, and Read/Write services to support auditing, troubleshooting, and compliance. Implemented in three commits (Logon Service Logging, Adding logging for security service, Read Write Service Log), providing end-to-end visibility and consistent service-level logs for faster root-cause analysis. No major bugs fixed this period; the work focused on feature delivery and improving diagnostics. Overall impact includes improved traceability, faster incident response, and stronger security posture. Technologies/skills demonstrated include observability instrumentation, centralized logging, service-level logging, auditing, and incident response readiness within the cisagov/icsnpp-c1222 repository.

Jan 1, 2025January 2025 (Month: 2025-01) monthly summary for cisagov/icsnpp-c1222. Key feature delivered: Zeek C1222 UserInformation logging with a new log type capturing MAC, padding, and whether data is encrypted or plain epsem; refactored service code extraction logic for readability and maintainability. Major bug fixed: MAC logging corrected to hex string representation for consistent data handling. Overall impact: improved observability, data handling, and business insights into user-related data flows; maintainability benefits from code refactor. Technologies/skills demonstrated: Zeek protocol analyzer, enhanced logging and observability, hex encoding, data handling, and code refactor for maintainability.
