§1504 Sharing of cyber threat indicators and defensive measures with the Federal Government
Title 6 › Chapter CHAPTER 6— - CYBERSECURITY › Subchapter SUBCHAPTER I— - CYBERSECURITY INFORMATION SHARING › § 1504
Summary
The Attorney General and the Homeland Security Secretary must write rules and help build a system for sharing information about cyber threats and ways to defend against them. They had to publish temporary rules within 60 days after December 18, 2015, and final rules within 180 days. Homeland Security had to build a real‑time system within 90 days so companies and others can send threat data and defenses to the federal government. That system must send the information automatically to the right federal agencies. Any delay to real‑time sharing is only allowed if all agency heads agree first, is done before any agency uses the data, and is applied the same way to each agency. The President can pick another federal agency to run a similar system, but must tell Congress at least 30 days before doing so. The Attorney General and the Homeland Security Secretary must also publish privacy rules: interim ones in 60 days and final ones in 180 days, and review them at least every 2 years. Those rules must limit how long personal data can be kept, require quick destruction of personal data that is not needed, protect data from unauthorized access, include audits and penalties for misuse, and tell senders if their data is not a cyber threat. Giving threat information to the government does not waive legal privileges and can be marked as proprietary. Shared information is exempt from public records release. Federal use of the data is limited to cybersecurity purposes, finding threats or vulnerabilities, responding to serious threats (including death, serious injury, or serious economic harm), protecting minors, and preventing or prosecuting certain crimes (for example, fraud and identity theft in 18 U.S.C. 1028–1030, espionage, and trade‑secret offenses). Generally the information cannot be used to regulate or punish lawful business activity, except in narrow cases tied to cybersecurity rules or procedures in this law.
