Restricting Web server access to a secure connection
Using the default configuration of the Web server, you can access the SINAMICS frequency
converter via an HTTP connection as well as via the encrypted HTTPS connection. Using
the configuration, access can be restricted so that only the secure HTTPS connection is
possible.
NOTICE
Software manipulation when using non-encrypted connections (HTTP)
When using the HTTP protocol, the login data is also sent unencrypted. This facilitates
password theft attacks, for example, and can lead to data manipulation by unauthorized
parties and thus ultimately to damages.
• Limit access to secure connections so that all data is transferred encrypted.
The configuration option provided to limit connections to HTTPS can only be changed when
the Web server is active.
● In the STARTER configuration dialog (see image "Configuring the Web server with
default settings")
● in the Web server prior to commissioning
● via parameter p8986
Procedure:
1. In the configuration dialog box, activate the "Only permit access via secure connection
(HTTPS)" checkbox.
2. If you do not want to assign passwords for read and write access (see Section "Assigning
a password (Page 433)"), click "OK".
The basic configuration of the Web server is then completed.
Access to the web server via the PROFINET interface X150 (configuring):
You can configure HTTP/HTTPS access to the web server via a PROFINET interface with
parameters p8986.1, p8984, and p8985. To do this, you must activate access to the web
server with p8986.0 = 1 or via the "Web server configuration" dialog (see "Activating or
deactivating the web server").
