General security measures
4.3 System integrity
Note
Before installing Microsoft Updates, note the following important points:
● Before installing the update, carefully check whether the current update is really compatible
with your system. You are responsible for the installation of the update!
● Never establish a direct connection to the WSUS server in the Internet! Ensure that the
environment is secure and install an intermediate layer (e.g. DMZ network, firewall,
SCALANCE S modules, etc.).
Product software
Note
Out-of-date product software also represents a potential security gap for attacks. As a
consequence, always install the latest product software versions.
