CAN Bus Security

# CAN bus tools
cansniffer vcan0                              # Monitor CAN traffic
candump vcan0 -l                              # Log to file
cansend vcan0 123#DEADBEEF                    # Send raw CAN frame

# Common CAN IDs
# 0x100-0x1FF: Engine/Drivetrain
# 0x200-0x2FF: ABS/Brakes
# 0x300-0x3FF: Body/Comfort
# 0x400-0x4FF: Infotainment
# 0x500-0x5FF: Diagnostics

ISO 21434 (Road Vehicles — Cybersecurity Engineering)

phases:
  concept:
    - Item definition

EV Charging Security

# OCPP vulnerabilities
# OCPP 1.6 (SOAP) vs 2.0.1 (WebSocket + JSON)
# Attack vectors:
# - Unauthenticated firmware updates
# - Meter tampering
# - Over-the-air commands without signature
# - RFID card cloning (MIFARE Classic)

# OCPP security checklist
# □ TLS 1.2+ between charger and CSMS
# □ Client certificate authentication
# □ Signed firmware updates
# □ Secure element in charging station
