9.10 Possible security gaps on standard IT interfaces:

preventing illegal access

With various SIMATIC NET components, such as switches, a wide range of

parameter assignment and diagnostic functions (for example, Web servers,

network management) are available over open protocols and interfaces. The

possibility of unauthorized misuse of these open protocols and interfaces by third

parties, for example to manipulate data, cannot be entirely excluded.

When using the functions listed above and these open interfaces and protocols (for

example, SNMP, HTTP), you should take suitable security measures to prevent

unauthorized access to the components and the network particularly from within

the WAN/Internet.

Notice

We expressly point out that automation networks must be isolated from the rest of

the company network by suitable gateways (for example using tried and tested

firewall systems). We do not accept any liability whatsoever, whatever the legal

justification, for damage resulting from non-adherence to this notice.

If you have questions on the use of firewall systems and IT security, please contact

your local Siemens office or representative. You will find the address in the

SIMATIC catalog IK PI or on the Internet at
