Aims:

Students will be able to specify usability criteria that a security mechanism has to meet to be workable for end-user groups and work contexts. They will know the strengths and weaknesses of particular security mechanisms in practice, and hence be able to choose and configure mechanisms for best performance in a given organisational context. Students will be able to specify accompanying measures (policies, training, monitoring and ensuring compliance) that a user organisation needs to implement to ensure long-term security in practice.

Learning outcomes:

On successful completion of the module, a student will be able to:

Apply their knowledge of human factors and behavioural economics to specify and implement workable and effective security solutions, and manage security behaviour.
