\inmodule QtServiceFramework
\ingroup servicefw
\brief The QAbstractSecuritySession class provides a generic mechanism to enable
permission checks for services.
QAbstractSecuritySession describes the abstract interface that security/permission
engines must implement in order to provide capability related functionality.
A QAbstractSecuritySession encapsulates the service client's capabilities. QServiceManager
can match those capabilites with the capabilites required by a particular service.
Service capabilites are declared via the services XML description.
The use of a security session is not mandated by the service manager. If the client
is passing a security session object QServiceManager ensures that the permissions
are checked before the requested service is loaded and forwards the session to the
service in case the service intends to implement additional checks. If no security
session is passed to QServiceManager capability checks are not performed. Note that
the security session is no substitute for platform security such as control over
a processes ability to load arbitrary plug-ins.
Since the service loader controls whether a security session is passed to the
QServiceManager instance it is assumed that the calling context can be trusted. Possible
use cases for a security session could be arbitrary Javascript applications which run
within a trusted browser environment. The QAbstractSecuritySession interface would allow
the browser to provide access to platform services while at the same time being able to
ensure that certain Javascript application (depending on e.g their context, URL or signatures)
can not access more sensitive system services.
Framework clients with purely native code bases are likely to never have any security sessions.
