- Per http://ics-cert.us-cert.gov/pdf/ICSA-13-079-03.pdf INSECURE PASWORD STORAGE User credentials for the HMI’s Web application are stored within the HMI’s system. These data are obfuscated in a reversible way and arereadable and writable for users with physical access or Sm@rt Server access to the system.
