4 4 Secure Interaction Design Designing a computer system to protect the interests of its legitimate user

5 5 Problems Viruses Spyware Phishing Online tracking Unintentional disclosure of information

6 6 Mental Models For software to protect its users interests, its behavior should be consistent with the user’s expectations. What the user thinks is happening What is shown in the interface What is really happening

7 7 Designation vs. Admonition Security by designation  When a user designates an action, take appropriate security related actions  Double clicking a Word document Security by admonition  Provide notifications that the user looks at and takes appropriate action from  Display a warning when the user tries to do something dangerous

8 8 Design Principles Know your audience Think like your audience Eliminate clutter Eliminate complexity Create just enough feedback Be a customer advocate when usability and competitive pressure collide

9 9 Know Your Audience Who are they? What skills do they have? If you don’t know who they are you can’t think like them If your product doesn’t match your audience then it will not do as well as it could have

10 10 Think Like Your Audience Present your design to other people to get feedback Think of a representative of your audience and design for them  Could my mother use this?

11 11 Eliminate Clutter Think about the tasks the user needs to perform If a word or button is not necessary to those tasks then remove it

12 12 Eliminate Complexity Again what are the tasks the user needs to perform Dose your design allow them to complete these tasks in the simplest manner Design for the common tasks, don’t sacrifice usability of common tasks for usability of rare or unlikely tasks

13 13 Create Just Enough Feedback Users just want it to work If it can be done safely without their involvement do it They want to be reassured it is working in unobtrusive ways

14 14 Be a Customer Advocate When Usability and Competitive Pressure Collide Its your job to make sure that customers don’t suffer from poor design Be willing to compromise with developers if it gets a better interface

Using the petname tool, you can save a reminder note about a relationship you have with a secure site. The petname tool will then automatically display this reminder note every time you visit the site. After following a hyperlink, you need only check that the expected reminder note is being displayed. If so, you can be sure you are using the same site you have in the past.” 1
