MultiSmart Installation & Operation Manual
39 Appendix D – MultiSmart Web Security Explained
Similar to the security for accessing MultiSmart menus, different users of the MultiSmart web pages can
be given different levels of security for accessing the pages. Users with same access permissions are
grouped into user groups. A user has his/her group details defined as part of the attributes.
All web page security details are stored on a MultiSmart in /var/www/htdocs/security.xml. User details can
be managed via the Security web page. However, it is also possible to reconfigure user groups and
access levels for each group. These advanced changes require direct editing of this configuration file.
Each user has the following configuration attributes:
Name Description
UserId The unique id of the user.
UserName Name of the user.
UserGroup
The group to which this user belongs. Each user group has a name and its own
access permissions for different screens.
Password Password to be entered to login.
Each group has the following attributes:
Name Description
Name Name of the user group.
Mask Mask of screens for which this user group has access.
Each web page can be assigned a unique level of security. This is achieved by assigning a unique mask
to each page requiring restricted access.
Screens which require restricted access will have the following attributes
Name Description
Name Screen Name
Operation
Operation defines the specific operation for the screen for which access is restricted.
Operation can be either READ or WRITE. If operation is READ, then unauthorized
users are not able to access the screen, where as if it is WRITE, then all users can
access the screen, but only authorized users can make any changes to the values on
Mask Unique mask controlling the restricted access.
There aren’t any users defined by default, which means that web page security is disabled by default.
Users are classified into four user groups – Operator, Electrician, Scada Engineer and Administrator.
Each user group has different access levels.
