The Surveillance State Repeal Act would roll back some of the worst constitutional abuses that have resulted from the US government's widespread spying practices. While it has received backing across the political spectrum, the act needs broad public support to become a reality.

Across some of the most crucial sectors of the American economy, there's a lack of consensus of what exactly should be considered a 'cyberincident' – and whether technical mishaps, even without malicious intent, should count. That's a problem.

In an Op-Ed provided by our partners at the Information Technology and Innovation Foundation, the director of the Cyber Security Policy and Research Institute at the George Washington University argues that engineering trust can help avoid a new battle over data encryption.

The vast majority of Passcode Influencers oppose weakening encryption so that law enforcement could have easier access to personal data. In fact, many say that stronger privacy protections will ultimately improve national security.

The Sony hack demonstrated that modern warfighting will be defined as much by circuits and networks as by missiles and guns. Therefore, we need a new war cabinet comprised of cybersecurity experts from government and the private sector to ensure the US can respond in real time to the next massive breach.

Maintaining anonymity against powerful surveillor is nearly impossible. Even the most skilled hackers and spies risk discovery. In an era when everything is tracked and stored, we either need more robust ways of preserving anonymity – or to give up on the idea entirely.
