Recommendations on network security 2
NOTICE
Information security
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 con󹪝guration data.
To prevent unauthorized access to the device and/or network, observe the following security
recommendations.
General
• Check the device regularly to ensure that these recommendations and/or other internal
security policies are complied with.
• 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/Seiten/
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.
• No product liability will be accepted for operation in a non-secure infrastructure.
• Use VPN to encrypt and authenticate communication from and to the devices.
• For data transmission via a non-secure network, use an encrypted VPN tunnel (IPsec,
OpenVPN).
• Separate connections correctly (WBM, Telnet, SSH etc.).
• Check the user documentation of other Siemens products that are used together with the
device for additional security recommendations.
• Using remote logging, ensure that the system protocols are forwarded to a central logging
server. Make sure that the server is within the protected network and check the protocols
regularly for potential security violations or vulnerabilities.
Physical access
• Restrict physical access to the device to quali󹪝ed personnel because the plug-in data medium
can contain sensitive data.
• Lock unused physical interfaces on the device. Unused interfaces can be used to gain access
to the plant without permission.
SCALANCE X-200
Operating Instructions, 11/2021, C79000-G8976-C284-15 13

Software (security functions)
• Keep the 󹪝rmware up to date. Check regularly for security updates for the device. You can
󹪝nd information on this at the Industrial Security (http://www.siemens.com/
industrialsecurity) website.
• Inform yourself regularly about security recommendations published by Siemens
ProductCERT (http://www.siemens.com/cert/en/cert-security-advisories.htm).
• Only activate protocols that you require to use the device.
• Disable encryption methods with a low security level.
• 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.
Authentication
Note
Accessibility risk - Risk of data loss
Do not lose the passwords for the device. Access to the device can only be restored by resetting
the device to factory settings which completely removes all con󹪝guration data.
• Replace the default passwords for all user accounts, access modes and applications (if
applicable) before you use the device.
•De󹪝ne rules for the assignment of passwords.
• Use passwords with a high password strength. Avoid weak passwords, (e.g. password1,
123456789, abcdefgh) or recurring characters (e.g. abcabc).
This recommendation also applies to symmetrical passwords/keys con󹪝gured on the device.
• Make sure that passwords are protected and only disclosed to authorized personnel.
• Do not use the same passwords for multiple user names and systems.
• Store the passwords in a safe location (not online) to have them available if they are lost.
• Regularly change your passwords to increase security.
• A password must be changed if it is known or suspected to be known by unauthorized
persons.
• When user authentication is performed via RADIUS, make sure that all communication takes
place within the security environment or is protected by a secure channel.
• Watch out for link layer protocols that do not o󹪜er their own authentication between
endpoints, such as ARP or IPv4. An attacker could use vulnerabilities in these protocols to
attack hosts, switches and routers connected to your layer 2 network, for example, through
manipulation (poisoning) of the ARP caches of systems in the subnet and subsequent
interception of the data tra󹪟c. Appropriate security measures must be taken for non-secure
layer 2 protocols to prevent unauthorized access to the network. Physical access to the local
network can be secured or secure, higher layer protocols can be used, among other things.

Certi󹪝cates and keys
• As of 󹪝rmware version V5.2.5, we converted from RSA certi󹪝cates to certi󹪝cates for elliptic
curves cryptography ("ECDSA certi󹪝cates"). Only use ECDSA certi󹪝cates in PEM format that
were generated with the following curves:
– secp256r1 (NIST P-256)
– secp384r1 (NIST P-384)
– secp521r1 (NIST P-521)
RSA certi󹪝cates are no longer supported as of this 󹪝rmware version. The existing RSA
certi󹪝cates on the device are automatically replaced with self-signed ECDSA certi󹪝cates.
• On the device there is a preset SSL certi󹪝cate with the key length 256 bits for the elliptic-
curves cryptography. Replace this certi󹪝cate with a self-made certi󹪝cate with key. We
recommend that you use a certi󹪝cate signed either by a reliable external or by an internal
certi󹪝cation authority.
• Use a certi󹪝cation authority including key revocation and management to sign certi󹪝cates.
• Make sure that user-de󹪝ned private keys are protected and inaccessible to unauthorized
persons.
• Verify certi󹪝cates and 󹪝ngerprints on the server and client to prevent "man in the middle"
attacks.
• Change certi󹪝cates and keys immediately if there is a suspicion of compromise.

SCALANCE X-200
Operating Instructions, 11/2021, C79000-G8976-C284-15 15

Secure/non-secure protocols
• 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 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
– LLDP
– DHCP Options 66/67
The following protocols provide secure alternatives:
– HTTP → HTTPS
– TFTP → FTPS
– Telnet → SSH
– SNTP → NTP
Check whether use the use of NTP is necessary. NTP is classi󹪝ed as non-secure. Activate
Secure NTP when the NTP server supports this protocol and use the authentication and
encryption mechanisms of Secure NTP.
– SNMPv1/v2c → SNMPv3
Check whether use of SNMPv1/v2c. is necessary. SNMPv1/v2c are classi󹪝ed 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 "DCP read-only" mode after commissioning.

Special features of the X-200IRT IE switches
The IRT variants were designed speci󹪝cally for setting up Industrial Ethernet networks with
isochronous/clock synchronous real-time communication. In addition to the properties named
above, the IRT switches also provide the following functions:
• IRT communication based on the combination of the switching methods cut through and
store and forward.
• Fast media redundancy thanks to an integrated redundancy manager for Fast Ethernet.
• Standby redundancy
Special features of the PRO variants
The devices with the "PRO" supplement are designed with degree of protection IP65 or IP67 for
use outside a cabinet. The characteristics of the IP67 degree of protection were not the subject
of the UL certi󹪝cation.
Frame delay times
The number of IE Switches X-200 connected in a line in󹪞uences the frame delay.
Note
Frame delay time with X‑200 without IRT
When a frame passes through X-200 IE switches, it is delayed by the Store&Forward function of
the X-200 IE switches.
• With a 64 byte frame length by approx. 10 microseconds (at 100 Mbps).
• With a 1500 byte frame length by approx. 130 microseconds (at 100 Mbps).
This means that the more IE Switch X-200 devices the frame passes through, the longer the
frame delay.
Note
Frame delay time with X‑200 with IRT
The more X-200IRT IE switches a frame runs through, the higher the frame delay. By using the
"cut through" switching mechanism, the X-200IRT IE switches are ideal to meet the real-time
requirements of PROFINET.
Cut through is, however, not possible:
• Between a port set to 10 Mbps and a port set to 100 Mbps.
• When two packets are to be sent at the same time on one port.
In this case, an X-200 IE switch changes to Store&Forward and the delay increases.
