Protecting the privacy of users and the information collected about them online is crucial to maintaining and growing a healthy and open Web. Unfortunately, there have been massive threats that weaken our ability to create the Web that we want to see. The most notable and recent example of this is the expansive surveillance practices of the U.S. government that were revealed by Edward Snowden. Even though it has been nearly two years since these revelations began, the U.S. Congress has failed to pass any meaningful surveillance reform, and is about to consider creating new surveillance authorities in the form of the Cybersecurity Information Sharing Act of 2015.

We opposed the Cyber Intelligence Sharing and Protection Act in 2012 – as did a chorus of privacy advocates, information security professionals, entrepreneurs, and leading academics, with the President ultimately issuing a veto threat. We believe the newest version of CISA is worse in many respects, and that the bill fundamentally undermines Internet security and user trust.

CISA is promoted as facilitating the sharing of cyber threat information, but:

• is overbroad in scope, allowing virtually any type information to be shared and to be used, retained, or further shared not just for cybersecurity purposes, but for a wide range of other offences including arson and carjacking;
• allows information to be shared automatically between civilian and military agencies including the NSA regardless of the intended purpose of sharing, which limits the capacity of civilian agencies to conduct and oversee the exchange of cybersecurity information between the private sector and sector-specific Federal agencies;
• authorizes dangerous countermeasures that could seriously damage the Internet; and
• provides blanket immunity from liability with shockingly insufficient privacy safeguards.

The lack of meaningful provisions requiring companies to strip out personal information before sharing with the government, problematic on its own, is made more egregious by the realtime sharing, data retention, lack of limitations, and sweeping permitted uses envisioned in the bill.

Unnecessary and harmful sharing of personal information is a very real and avoidable consequence of this bill. Even in those instances where sharing information for cybersecurity purposes is necessary, there is no reason to include users’ personal information. Threat indicators rarely encompass such details. Furthermore, it’s not a difficult or onerous process to strip out personal information before sharing. In the exceptional cases where personal information is relevant to the threat indicator, those details would be so relevant to mitigating the threat at hand that blanket immunity from liability for sharing would not be necessary.

We believe Congress should focus on reining in the NSA’s sweeping surveillance authority and practices. Concerns around information sharing are at best a small part of the problem that needs to be solved in order to secure the Internet and its users.
