C. Trusted security entity
A trusted security entity concept is more dynamic, but
currently does not cover all security aspects of cloud
computing. It is mostly focused on identity and access
management, ignoring infrastructure, network, and
application security.
The existing solutions, especially for ad hoc
collaborations, do not cover the whole aspects of cloud
security or need sufficient evidence for their
implementation, e.g., monitoring and logging tools in place,
or regular auditing. Some legal aspects can be outsourced to
such trusted entities (authorities) that can assume the
liability and responsibility.
