All
transactions between the Altitude Server and the User are subject to security
procedures that ensure the data on the system is protected from unauthorized
access. Altitude uses secure user
authentication employing encryption and 128-bit industry standard MD5 digital
signatures.
Data
may be set to Read Only, Read/Write (full access) or no access. This feature
allows the security administrator to permit different users to access different
features of the system. For example, a user with no access rights to a
particular group of related information would see no graphics or data on pages
containing this information whereas a user with full access rights would be able
to view this information and make changes to it.
Security
is based on users and groups; each user has an individual profile (user name,
logon ID, password etc.) and may belong to one or more groups. Each group is
then granted access to data items in the system as required.
Access may be granted at any level on the data
hierarchy, at an individual data item level or node level (or pre-defined group
of data items).
