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.

Recommendations on network security

NOTICE
Information security
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.
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 (https://www.industry.siemens.com/topics/global/en/industrial-
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.).
Physical access
●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.
–Using the button, you can reset the device to the factory defaults.
●If the device is publicly accessible, disable the functions of the button using the software.
●Lock unused physical ports on the device. Unused ports can be used to gain forbidden
access to the plant.

Recommendations on network security
SCALANCE XR-500
14 Operating Instructions, 09/2018, A5E03275845-12
Software (security functions)
●Keep the firmware up to date. Check regularly for security updates for the device. You
can find information on this at the Industrial Security
(https://www.siemens.com/industrialsecurity) website.
●Inform yourself regularly about security recommendations published by Siemens
ProductCERT (https://www.siemens.com/cert/en/cert-security-advisories.htm).
●Only activate protocols that you require to use the device.
●Restrict access to the management of the device with rules in an access control list
(ACL).
●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
self-made 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.

Recommendations on network security
SCALANCE XR-500
Operating Instructions, 09/2018, A5E03275845-12 15
Secure/non-secure protocols and services
●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 non-
secure. 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.

SCALANCE XR-500
16 Operating Instructions, 09/2018, A5E03275845-12
Interfaces security
●Disable unused interfaces.
●Use IEEE 802.1X for interface authentication.
●Use the function "Locked Ports" to block interfaces for unknown nodes.
●Use the configuration options of the interfaces, e.g. the "Edge Type".
●Configure the receive ports so that they discard all untagged frames ("Tagged Frames
Only").
