Mobile Dev + Test2016

The big idea Users will use, hackers will hack User experience Mobile security Wearables and IoT - usability vs. security Solution

The art The science

Usability and security do not have to compete Good usability can improve security Whats needed is more thought and better tools

Risk assessment Impact analysis Careful usability design Usability testing Usability & security analytics

Total Protection Point Protection ID & secure areas of high risk and impact

Does data security matter?

Do users value good app experience?

Do app store reviews matter?

Users wouldn't have to authenticate - permanent,

automatic, biometric authentication

Apps would have all data needed, at all times

All data would be secure

Servers would be protected

No data would be stolen

Stolen/lost devices

Jailbreaking

Rooting

Man-in-the middle attacks

Phishing attacks

Passwords have caused more security issues than probably any other factor

Weak/ineffective passwords have caused most of the hacks in recent years

Spear phishing campaign can result in administrator's username and password

Non-admin user passwords are even harder to keep track of

Solution: Make passwords more complex Mix of capital letters Lowercase and alpha Min length

Drawbacks 70% of users forget a password if too long and/or complex. (Source: Ponemon

Institute) 90% of users would just leave a site if they have forgotten a password, instead

of recovering it. (Source: Janrain) 40% of respondents at least sometimes, or often, write passwords down

(Source: Berkeley University Study) 7.9 - number of unique passwords for an average user (Source: Janrain)

Most passwords are not strong enough: users tend to choose meaningful, natural language words that they can remember

However, overzealous password rules can be annoying.

Password for the DHS E-file: Contain from 8 to 16 characters Contain at least 2 of the following 3 characters: uppercase alphabetic, lowercase

alphabetic, numeric Contain at least 1 special character (e.g., @, #, $, %, & *, +, =) Begin and end with an alphabetic character Not contain spaces Not contain all or part of your UserID Not use 2 identical characters consecutively Not be a recently used password

Biometrics Fingerprints Iris recognition Facial recognition Voice recognition

Tokens Physical Software

Better user engagement More secure apps Better reviews in the app store, which leads to

Increased sales in the app store Brand value

Better compliance Solid user and community growth

A threat model focuses on the intersection of likely attack vectors with the points of human interaction. The resulting area provides the surface to what needs to be monitored for user behavior and assessed for vulnerabilities.

User engagement - before & after sign up Drops in sign ups Password/PIN issues Forgot my password Response times to auth Usage of biometric devices

https://www.owasp.org/index.php/Application_Threat_Modeling

App authentication API authentication App authorization API authorization Cookie management Data/Input validation Encryption Local storage

Error Handling/Information leakage Logging/Auditing Secure transport Certificate/key management Secure Code Environment Session Management

Create UX metrics - e.g. sign up dropout rate Create A/B split tests Use app analytics to monitor user behavior Discover the balance point between security and usability

Usability and security can coexist

True security is an outcome of great user experience

Cross-functional teams are key

Model, measure, tweak.

Repeat.
