Cyber Intelligence Sharing and Protection Act (CISPA)

The Cyber Intelligence Sharing and Protection Act (CISPA) is a piece of legislation designed to thwart cyber-criminals by allowing corporations to share data about users with the government. It's not yet law, but it has been introduced three times since 2011, and is still under consideration.

CISPA is essentially an upgrade to the 1974 National Security Act, and it aims to empower the government to acquire cyber threat intelligence. While CISPA is widely supported by corporations, it has been hit with criticism from privacy and civil liberties organizations.

CISPA also spawned a related bill, the Cybersecurity Information Sharing Act of 2015 (CISA). CISA has been referred to as a "zombie" version of the original CISPA bill, and has now been signed into law.

The Pros and Cons of CISPA

CISPA was designed to protect against two main outcomes: information security breaches, and cyber-security threats.

It proposed a mechanism where private companies would be allowed to share data with the government, in an effort to highlight suspicious activity, or communications that could indicate threats.

The bill would give the US government the power to monitor the use of networks and services, as well as allowing data sharing to prevent crime and threats to children.

Importantly, CISPA would also allow the government, and the National Security Agency (NSA), to monitor private communications that take place online. That data could be accessed without a warrant.

The bill has been amended several times. One addition includes the provision for penalties if the government or corporations misuse data for any purpose other than fighting cyber crime.

But the Electronic Frontier Foundation is one of many organizations that believe CISPA will open the door to infringing civil liberties, and they say that the amendments don't go far enough.

CISPA was supported by more than 800 companies, represented by an array of trade organizations. These include Verizon, IBM, Microsoft, and Intel, as well as the United States Chamber of Commerce.

Google has offered limited support, but it says that CISPA needs more work before it should be implemented. Opponents to CISPA include the Electronic Frontier Foundation and the American Civil Liberties Union, as well as businesses like Apple and Twitter.


Privacy campaigners say that CISA gives corporations and governments near-identical powers as CISPA; both would protect companies that handed over personal data about cyber threats.

However, under CISPA, the NSA would handle the data. Under CISA, it is managed by the Department of Homeland Security. However, the bill grants the same immunity to companies that actually share that data. And the data could still be passed — uncensored — to the NSA, as well as the FBI.

CISA was brought into law in December 2015 as part of a much bigger piece of funding legislation. Critics say that this was a way to bring CISA into law without further debate, simultaneously bypassing the President's right to veto it.

Implications for Non-US Citizens

Like many US laws, CISA may affect citizens of other countries too. CISA could result in non-US citizens being prosecuted under US law, if they are thought to be involved with a cyber crime that affects a company based in the US.

In a Guardian article, the given example is a French hacker who compromises a Spanish person's MasterCard account. That could result in the French hacker being jailed in the USA.

In practice, many countries have similar legislation already. For example, the United Kingdom has its own Cyber Security Information Sharing Partnership, which has a similar purpose.
