Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.

Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.

Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
http://www.siemens.com/industrialsecurity (http://www.siemens.com/industrialsecurity)

Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

Connect to the device and change the standard password for the user set in the factory
"admin" and "" before you operate the device.

To prevent unauthorized access, note the following security recommendations.

● You should make regular checks to make sure that the device meets these

recommendations and/or other security guidelines.

● Evaluate your plant as a whole in terms of security. Use a cell protection concept with

suitable products (http://www.industry.siemens.com/topics/global/en/industrial-

security/network-security/Pages/Default.aspx).

● When the internal and external network are disconnected, an attacker cannot access

internal data from the outside. Therefore operate the device only within a protected
network area.

● For communication via non-secure networks use additional devices with VPN functionality

to encrypt and authenticate the communication.

● Terminate management connections correctly (WBM. Telnet, SSH etc.).

● Restrict physical access to the device to qualified personnel.

– The memory card or the PLUG (C-PLUG, KEY-PLUG) contains sensitive data such as

certificates, keys etc. that can be read out and modified.

Secure/non-secure protocols and services

2.1 Security recommendations

● Avoid or disable non-secure protocols and services, for example HTTP, Telnet and TFTP.

For historical reasons, these protocols are available, however not intended for secure
applications. Use non-secure protocols on the device with caution.

● Check whether use of the following protocols and services is necessary:

– Non authenticated and unencrypted ports

– MRP, HRP

– IGMP snooping

– LLDP

– Syslog

– RADIUS

– DHCP Options 66/67

– TFTP

– GMRP and GVRP

● The following protocols provide secure alternatives:

– HTTP → HTTPS

– Telnet → SSH

– SNMPv1/v2c → SNMPv3

Check whether use of SNMPv1/v2c. is necessary. SNMPv1/v2c is classified as non­secure. Use the option of preventing write access. The device provides you with
suitable setting options.

If SNMP is enabled, change the community names. If no unrestricted access is
necessary, restrict access with SNMP.

Use the authentication and encryption mechanisms of SNMPv3.

● Use secure protocols when access to the device is not prevented by physical protection

measures.

● If you require non-secure protocols and services, operate the device only within a

protected network area.

● Restrict the services and protocols available to the outside to a minimum.

● For the DCP function, enable the "Read Only" mode after commissioning.

● If you use RADIUS for management access to the device, activate secure protocols and

services.

Defining the fault mask

Enabling/disabling the redundancy manager

Initial situation:

Result:

Initial situation:

Result:

3.2 SELECT/SET button

Using the fault mask, you specify an individual "good status" for the connected ports and the
power supply. Deviations from this status are displayed as errors/faults.

To define the fault mask, follow the steps below:

1. Change to display mode D.

Display mode D is active when the "DM1" and "DM2" LEDs are lit green.
If a different display mode is active, press the "SET/SELECT" button several times briefly,
until the "DM1" and "DM2" LEDs are lit green.

2. Hold down the "SELECT/SET" button for 5 seconds.

After 2 seconds, the "DM1" and "DM2" LEDs start to flash for 3 seconds. At the same
time the port LEDs go on one after the other.
After you have pressed the button for 5 seconds, the current settings are stored as the
"good status".
If you release the button before the 5 seconds are up, the previous fault mask is retained.

To enable/disable the redundancy manager, follow the steps below:

1. Change to display mode B.

Display mode B is active when the "DM1" LED is lit green and the and "DM2" LED is off.
If a different display mode is active, press the "SET/SELECT" button several times briefly,
until the "DM1" LED is lit green and the "DM2" LED is off.

2. Hold down the "SELECT/SET" button for 5 seconds.

After 2 seconds, the "DM1", "DM2" and "RM" LEDs start to flash for 3 seconds. At the
same time, the port LEDs light up one after the other.
If you release the button before the 5 seconds have elapsed, the action is canceled.

The result of the action depends on the initial situation:

–

The redundancy manager and media redundancy are disabled.

After enabling the redundancy manager, media redundancy is also enabled.

–

The redundancy manager and media redundancy are enabled.

After disabling the redundancy manager, media redundancy remains enabled.
