Usable Security - Design

1. The cycle of the iterative design process

• Requirements
• Design
• Developments
• Testing

2. The difference between system centered design and user centered design:

• System centered design is focused on what is easy to build on a platform while user centered design is focused on user needs and context

3. Good ways to incorporate user-centered design in the design of security systems can be

• Designing security around user tasks
• Designing security based on the user's environment and work context

4. NOT Good ways to incorporate user-centered design in the design of security systems

• Designing security based on what experts believe is best.

5. When designing error messages, followings are important factors to keep in mind for usability

• Use language that users will understand
• Make the most secure options part of the user's natural task
• Provide users with clear exits to get out of a security warning

6. If you were designing security for the entrance to a secure facility, which of the following should you consider?

• How often users enter and exit
• What tasks the users are in the middle of when they need to access the area.

7. Following are disadvantages of Personas:

• Too many personas can be difficult to create and manage.
• A diverse audience may be difficult to represent with a normal-sized set of personas

8. The advantages of low-fidelity (e.g. paper) prototypes:

• They can be created quickly and cheaply
• Any team member can create one, regardless of programming skills

9. Following are present in good interface design:

• Easy to recover from errors
• Minimal training needed for a person to use the system
• Relies on common interaction techniques for familiarity

10. Compute the efficiency of the underlying algorithms: is NOT an important part of the design process
11. Following is an important part of the design process:

• Prepare a prototype
• Consider usability guidelines
• Solicit user input

12. In participatory design and co-design: Average users have equal standing with designers
13. In participatory design and co-design, the following are not true

• Managers convey input from users to designers
• Users design the system on their own based on a list of constraints provided by designers
• Designers brainstorm and create prototypes after asking potential users questions
