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, itis
necessary to implement – and continuously maintain – aholistic, 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
Link: (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
Link: (https://www.siemens.com/industrialsecurity)
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
(https://support.industry.siemens.com/cs/ww/en/view/109479891)).
Note the different national regulations.

Security recommendations
1
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
suitable products.
Link: (https://www.industry.siemens.com/topics/global/en/industrial-
security/pages/default.aspx)
●Separate connections correctly (WBM. Telnet, SSH etc.).
Physical access
●Limit 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.
●Lock unused physical ports on the device. Unused ports can be used to gain forbidden
access to the plant.
Software (security functions)
●Keep the software up to date. Check regularly for security updates of the product.
You will find information on this on the Internet pages "Industrial Security
(https://www.siemens.com/industrialsecurity)".
●Inform yourself regularly about security advisories and bulletins published by Siemens
ProductCERT (https://www.siemens.com/cert/en/cert-security-advisories.htm).
●Only activate protocols that you really require to use the device.
●Restrict access to the management of the device with firewall rules.
●The option of VLAN structuring provides good 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.
●We recommend formatting a PLUG that is not being used.

Security recommendations
SCALANCE M874, M876
10 Operating Instructions, 08/2018, C79000-G8976-C331-08
Passwords
●Define rules for the use of devices and assignment of passwords.
●Regularly update passwords and keys to increase security.
●Change all default passwords for users before you operate the device.
●Only use passwords with a high password strength. Avoid weak passwords for example
password1, 123456789, abcdefgh.
●Make sure that all passwords are protected and inaccessible to unauthorized personnel.
●Do not use the same password for different users and systems or after it has expired.
Keys and certificates
This section deals with the security keys and certificates you require to set up TLS, VPN
(IPsec, OpenVPN) and SINEMA RC.
●The device contains a pre-installed X.509 certificate with key. Replace this certificate with
a self-made certificate with key. We recommend that you use a certificate signed by a
reliable external or internal certification authority.
●Use the certification authority including key revocation and management to sign the
certificates.
●Make sure that user-defined private keys are protected and inaccessible to unauthorized
persons.
●Verify certificates and fingerprints on the server and client to prevent "man in the middle"
attacks.
●It is recommended that you use password-protected certificates in the PKCS#12 format.
●It is recommended that you use certificates with a key length of at least 2048 bits.
●Change keys and certificates immediately, if there is a suspicion of compromise.
Secure/non-secure protocols
●Avoid or disable non-secure protocols, for example Telnet and TFTP. For historical
reasons, these protocols are still available, however not intended for secure applications.
Use non-secure protocols on the device with caution.
●Avoid or disable non-secure protocols. Check whether use of the following protocols is
necessary:
–Broadcast pings
–Non authenticated and unencrypted interfaces
–ICMP (redirect)
–LLDP
–Syslog
–DHCP Options 66/67
–TFTP

Security recommendations
SCALANCE M874, M876
Operating Instructions, 08/2018, C79000-G8976-C331-08 11
●The following protocols provide secure alternatives:
–SNMPv1/v2 → SNMPv3
Check whether use of SNMPv1 is necessary. SNMPv1 is classified as non-secure.
Use the option of preventing write access. The product provides you with suitable
setting options.
If SNMP is enabled, change the community names. If no unrestricted access is
necessary, restrict access with SNMP.
–HTTP → HTTPS
–Telnet → SSH
–TFTP → SFTP
●Use secure protocols when access to the device is not prevented by physical protection
measures.
●To prevent unauthorized access to the device or network, take suitable protective
measures against non-secure protocols.
●If you require non-secure protocols and services, activate these at interfaces that are
located within a protected network area.
●Using a firewall, restrict the services and protocols available to the outside to a minimum.
●For the DCP function, enable the "DCP read-only" mode after commissioning.
