Introduction
1.1 Information on the Operating Instructions
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 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under

Security recommendations
2
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.
● 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, security PLUG) contains sensitive
data such as certificates, keys etc. that can be read out and modified.
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
(http://www.siemens.com/industrialsecurity)".
● Inform yourself regularly about security advisories and bulletins published by Siemens
ProductCERT (http://www.siemens.com/cert/en/cert-security-advisories.htm).
● Only activate protocols that you really require to use the device.
● Use the security functions such as address translation with NAT (Network Address
Translation) or NAPT (Network Address Port Translation) to protect receiving ports from
access by third parties.
● Restrict access to the device with a firewall or rules in an access control list (ACL Access Control List).
● If RADIUS authentication is via remote access, make sure that the communication is
within the secured network area or is via a secure channel.
● The option of VLAN structuring provides good protection against DoS attacks and
unauthorized access. Check whether this is practical or useful in your environment.

Operating Instructions, 01/2017, A5E03692120-11

Security recommendations
● Enable logging functions. Use the central logging function to log changes and access
attempts centrally. Check the logging information regularly.
● Configure a Syslog server to forward all logs to a central location.
● Use WPA2/ WPA2-PSK with AES to protect the WLAN. If iPCF or iPCF-MC is used, use
the AES encryption.
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 HTTPS (
HyperText Transfer Protocol Secured Socket Layer).
● We strongly recommend that you create your own HTTPS certificates and make them
available.
There are preset certificates and keys on the device. The preset and automatically
created HTTPS certificates are self-signed.
We recommend that you use HTTPS certificates signed either by a reliable external or by
an internal certification authority. The HTTPS certificate checks the identity of the device
and controls the encrypted data exchange. You can install the HTTPS certificate via the
WBM (System > Load and Save).
● Handle user-defined private keys with great caution if you use user-defined SSH or SSL
keys.
● Use the certification authority including key revocation and management to sign the
certificates.
● Verify certificates and fingerprints on the server and client to avoid "man in the middle"
attacks.
● We recommend that you use certificates with a key length of 2048 bits.
● Change keys and certificates immediately, if there is a suspicion of compromise.
Secure/non-secure protocols
● For the DCP function, enable the "DCP read-only" mode after commissioning.
● Avoid and 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.
SCALANCE W788C-2

Operating Instructions, 01/2017, A5E03692120-11
Security recommendations
● 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.
Use SNMPv3 in conjunction with passwords.
– HTTP → HTTPS
– Telnet → SSH
– SNTP → NTP
● 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, operate the device only within a
protected network area.
● Restrict the services and protocols available to the outside to a minimum.
