VEGACOM 558 as web server
7.8 User Management
The web server of VEGACOM 558 enables the user to read out all meas-
ured values of the level measuring system, or to spy on them, so to
speak to. In addition, fundamental configurations such as authentication,
mailing lists etc. can be modified. To avoid inadvertent or deliberate
manipulation of the data bank of VEGACOM 558, the web service must
be protected against unauthorised access.
For this purpose, the VEGACOM 558 web server offers basic functions
for user management. The user management system works directory-
oriented, i.e. access authorisation can be defined for certain directories.
To keep the complexity of user management to a minimum, VEGACOM
558 does not offer the option of defining new user authorisations to cre-
ate new user groups. Rather, ten fixed user groups with fixed user rights
are stored in VEGACOM 558.
The administrator of VEGACOM 558 can now assign any number of
users with hteir individual passwords to these ten user groups. The
allocations are made via the web browser in the menu item "User man-
User man- User man- User man- User man-
agement agement agement agement agement" on the VEGACOM 558 web pages.
