Notes

General Security Measures
As general security measures, SICK recommends to minimize network exposure of the devices, restrict network access and follow recommended security practices in order to run the devices in a protected IT environment.
Vulnerability Classification
SICK performs vulnerability classification by using the CVSS scoring system (*CVSS v3.1*). The environmental score is dependent on the customer’s environment and can affect the overall CVSS score. SICK recommends that customers individually evaluate the environmental score to achieve final scoring.
