An NTP server makes the time available to the NTP clients.
NTP (secured)
NTP (secure) allows for secure and authenticated time synchronization by means
of authentication methods and a joint encryption code. Both the NTP server and
the NTP clients must support this function.
A secure time synchronization is supported by CP x43-1 Advanced V3 and CP
1x43-1, if the Security Function is activated and the expanded NTP configuration
has been explicitly activated in the configuration.The Hypertext Transfer Protocol () is part of the family of protocols

primarily used for loading websites from a web server to a web browser.

Data transported via are readable as plain text and can be intercepted by
third parties.
Today particularly – in the age of online banking, online shopping, and social
networks – it is important that the transmission of confidential and personal data is
secure and protected against unauthorized access.
The Hypertext Transfer Protocol Secure (S) is the easiest way of securely
transmitting data.
S has the same structure as the protocol, but in addition it uses the
Secure Socket Layer Protocol for encryption.
Many of the latest models of SIMATIC CPU's and CP's support S, and can
be configured to use S exclusively, providing an increased level of security
for data transmission.
3.4.4 Simple Network Management Protocol (SNMP)
Descrtion
SNMP – Simple Network Management Protocol – is a UDP-based protocol that
was specified particularly for the administration of data networks and in the
meantime has established itself also as a de facto standard for TCP/ devices.
The individual nodes in the network – network components or terminals – feature a
SNMP agent that provides information in a structured form. This structure is
referred to as MIB (Management Information Base). In the network node, the agent
is usually implemented as firmware functionality.
Management Information Base – MIB
An MIB (Management Information Base) is a standardized data structure consisting
of different SNMP variables, which are described by a language independent of the
target system. Due to the cross-vendor standardization of MIBs and access
mechanisms, even a heterogeneous network with components from different
manufacturers can be monitored and controlled. If component-specific, nonstandardized
data is necessary for network monitoring, this data can be described
by the manufacturers in “private MIBs”.
Secure SNMP (SNMPv3)
There are several versions of SNMP: SNMPv1, SNMPv2, and SNMPv3. The
original version SNMPv1 and SNMPv2 are sometimes still used. However, it is
recommendable not to use SNMPv1 and SNMPv2 since security mechanisms
have not been implemented in these versions, or only in a restricted way.
From version 3, SNMP additionally offers user administration with authentication
and optional encryption of data packages. Security with SNMP was substantially
improved by these aspects.
The secure SNMP is supported by CP x43-1 Advanced V3 and CP 1x43-1, if the
Security Function is activated and SNMPv3 has been explicitly activated in the Security in industrial automation can only be achieved if manufacturers, suppliers,
users and operators cooperate. An important part of the cooperation is the creation
