Secure Software Development requires process improvement
- Simply "looking for bugs" doesn't make software secure
- Must reduce the chance vulnerabilities enter into design and code
- Requires executive commitment
- Requires ongoing process improvement
- Requires education & training
- Requires tools and automation
- Requires incentives and consequences

What is Privacy?
- Telling users what data is collected and how it will be used.
- Giving users a choice when their data will be used for purposes other than originally disclosed.
- Ensuring data is protected and can only be used for the purposes disclosed.
- Ensuring data practices comply with Federal, State and International laws.

Privacy and Security
Privacy: Empowering users to control collection, use, and distribution of their personal information.
Security: Establishing protective measures that defend against hostile acts or influence and provides assurance of defense.

Implicit Consent
Also known as deemed or indirect consent can mean two things:
-

-

Opt-out consent
Opt-out consent — also known as giving consent by not declining to give consent — means that an individual is given the option to decline consent. If the individual does not clearly decline consent, consent is granted. Opt-out consent is usually done in writing.
Many organizations, especially websites, use opt-out consent as a way to request permission to use your personal information for other purposes.
