We have thus far concentrated only on the specific ideas of ensuring that a user is who they say they are and that only the correct users can view and use data. However, once we have taken the appropriate steps and confirmed these details, we still need to ensure that this data is secure when the user is actually using it; there are a number of areas to consider:
