Security information
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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary and
only when appropriate security measures (e.g. firewalls and/or network segmentation) are in
place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customers’ exposure to cyber
threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under
https://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity)
You will find the article numbers for the Siemens products of relevance here in the following
catalogs:
● SIMATIC NET Industrial Communication / Industrial Identification, catalog IK PI
● SIMATIC Products for Totally Integrated Automation and Micro Automation, catalog ST 70
● Industry Mall - catalog and ordering system for automation and drive technology, Online
catalog (https://mall.industry.siemens.com/goos/WelcomePage.aspx?regionUrl=/
de&language=en)
You can request the catalogs and additional information from your Siemens representative.
If a fault develops, please send the device to your SIEMENS service center for repair. Repairs
on-site are not possible.
Recycling and disposal
The products are low in pollutants, can be recycled and meet the requirements of the WEEE
directive 2012/19/EU for the disposal of electrical and electronic equipment.
Do not dispose of the products at public disposal sites.
For environmentally friendly recycling and the disposal of your old device contact a certified
disposal company for electronic scrap or your Siemens contact (Product return (
Note the following safety notices. These relate to the entire working life of the device.
You should also read the safety notices relating to handling in the individual sections,
particularly in the sections "Installation" and "Connecting up".
CAUTION
To prevent injury, read the manual before use.
Safety notices on use in hazardous areas
General safety notices relating to protection against explosion
WARNING
EXPLOSION HAZARD
2
Do not open the device when the supply voltage is turned on.
Safety notices when using the device according to Hazardous Locations (HazLoc)
If you use the device under HazLoc conditions you must also keep to the following safety
notices in addition to the general safety notices for protection against explosion:
This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or non-hazardous
locations only.
This equipment is suitable for use in Class I, Zone 2, Group IIC or non-hazardous locations only.
Connect to the device and change the standard passwords for the users "admin" and "user"
before you operate the device. To be able to change passwords you need to be logged in with
write access to the configuration data.
To prevent unauthorized access, note the following security recommendations.
General
● 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
● The option of VLAN structuring provides protection against DoS attacks and unauthorized
access. Check whether this is practical or useful in your environment.
● Use a central logging server to log changes and accesses. Operate your logging server
within the protected network area and check the logging information regularly.
Passwords
● Define rules for the assignment of passwords.
● Regularly change your passwords to increase security.
● Use passwords with a high password strength.
● Make sure that all passwords are protected and inaccessible to unauthorized persons.
● Do not use the same password for different users and systems.
Certificates and keys
● On the device there is a preset SSL certificate with key. Replace this certificate with a selfmade certificate with key. We recommend that you use a certificate signed either by a
reliable external or by an internal certification authority.
● Use a certification authority including key revocation and management to sign certificates.
● Make sure that user-defined private keys are protected and inaccessible to unauthorized
persons.
● It is recommended that you use password-protected certificates in the PKCS #12 format
● Verify certificates and fingerprints on the server and client to prevent "man in the middle"
attacks.
● It is recommended that you use certificates with a key length of at least 2048 bits.
● Change certificates and keys immediately, if there is a suspicion of compromise.
● Avoid or disable non-secure protocols, for example Telnet and TFTP. For historical reasons,
these protocols are available, however not intended for secure applications. Use nonsecure protocols on the device with caution.
● Check whether use of the following protocols and services is necessary:
– Non authenticated and unencrypted ports
– MRP, HRP
– LLDP
– DHCP Options 66/67
The following protocols provide secure alternatives:
– HTTP → HTTPS
– TFTP → FTPS
– Telnet → SSH
– SNTP → NTP
– SNMPv1/v2c → SNMPv3
Check whether use of SNMPv1/v2c. is necessary. SNMPv1/v2c are 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.
Recommendations on network security
Available protocols
● 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 "DCP read-only" mode after commissioning.
The following list provides you with an overview of the open protocol ports.
The table includes the following columns:
● Protocol
● Port number
● Port status
– Open
– Closed
● Factory setting
Indicates the state of the port on delivery or after reset to factory settings.
The type designation of an IE Switch X-300 is made up of several parts that have the following
meaning:
Interfaces of devices without optical ports:
InterfaceProperty
FEElectrical RJ-45 port for 10/100 Mbps.
[-]Electrical RJ-45 port for 10/100 Mbps or 10/100/1000 Mbps.
Interfaces of devices with optical ports:
InterfaceProperty
FESC port 100 Mbps multimode FO cable (up to max. 5 km).
LD FESC port 100 Mbps single mode FO cable (up to max. 26 km).
[-]SC port 1000 Mbps multimode FO cable (up to max. 750 m).
LDSC port 1000 Mbps single mode FO cable (up to max. 10 km).
LHSC port 1000 Mbps single mode FO cable (up to max. 40 km).
LH+SC port 1000 Mbps single mode FO cable (up to max. 70 km).
If information applies to all devices, the term "IE Switches X-300" is used. If information applies
to only a particular product group, the relevant names will be used without extra information on
the type or number of interfaces. Examples: "X-300" stands for non-modular devices with a
compact housing, "XR-300" means all rack devices, "X-300M" means all modular devices etc.
Note
SCALANCE X320-3LD FE
The SCALANCE X320-3LD FE deviates from the type designation in that it has an SC port for
multimode fiber-optic cable up to a maximum of 5 km in length and two SC ports for single mode
fiber-optic cable up to a maximum of 26 km in length.
● Port 21: Multimode
● Port 22: LD (long distance, single mode)
● Port 23: LD (long distance, single mode)
