Cybersecurity Information Sharing Act (CISA, 2015)

1) Link to the Text of the Act
Read the statute (6 U.S.C. §§ 1501–1528)

2) Why It Was Done
The Act was passed to improve the nation’s cybersecurity defenses by encouraging private companies and the federal government to share cyber threat indicators. It was intended to help detect and prevent cyberattacks more quickly.

3) Pre-existing Law or Constitutional Rights
Before CISA, there was no comprehensive framework for private-sector cyber threat sharing. The Act raised concerns about Fourth Amendment privacy rights because of the potential for government access to personal data.
