Note:
In many SIMATIC NET components (e.g. SCALANCE, OSM/ESM, CPs with IT functions), extensive parameterization and diagnostics functions are provided over open protocols and interfaces (e.g. Web Server, network management).

These open interfaces provide access to those components, which can also be used for illicit activities.

When using the above-mentioned functions and these open interfaces and protocols (such as SNMP, HTTP and Telnet), suitable security measures must be implemented that block unauthorized access to the components or the network especially from the WAN/Internet.

Advice on the use of firewall systems and on IT security can be obtained from:
