8.2.2 Creating a .csipasswd file
The data logger employs a security code scheme that includes three levels of security (see Data
logger security (p. 111) for more information). This scheme can be used to limit access to a data
logger that is publicly available. However, the security codes are visible in Device Configuration
Utility. In addition, the range of codes is relatively small. To provide a more robust means of
security, Basic access authentication was implemented with the HTTP API interface in the form of
an encrypted password file named .csipasswd. Read/write access to the web interface
requires a .csipasswd file. The web interface provides access to real-time and stored data
logger data. For more information on the web interface, watch an instructional video.
NOTE:
Ethernet over USB (RNDIS) is considered a direct communications connection. Therefore, it is
a trusted connection and csipasswd does not apply.
