This report handles the creation of an access control map and the dening of asecurity policy for a healthcare communication system. An access control mapis a graphical way to describe the access controls of the subjects and objects ina system. We use a three step method to produce a graphical overview of theparts in the system, the interactions between them and the permissions of thesubjects. Regarding the security policy we create a read up and read down policylike the so called Ring policy, but adapt a write sideways approach. We alsoapply a mandatory access control which has a centralized authority that denesthe permissions of the subjects. Attribute restrictions is also included to thesecurity levels, to set an under limit for reading permissions.
