Which of the following is the first piece of legislation from Congress to address computer security?

The Computer Security Act of 1987 is significant as it represents the initial legislative effort by Congress to specifically address the issue of computer security. This act was motivated by growing concerns over the protection of sensitive government data and the need to establish a framework for securing federal computer systems. It mandated that federal agencies develop security plans for their computer systems and set forth guidelines for safeguarding sensitive information.

In contrast, the other options either came later or focused on different aspects of information management. The Federal Information Security Management Act, for example, expanded upon the earlier computer security legislation but was not the first. The Homeland Security Act primarily addressed national security and response to terrorism rather than computer security specifically, while the Paperwork Reduction Act centered on the management of information collection practices and reducing unnecessary paperwork, rather than the safeguarding of computerized information systems. Therefore, the Computer Security Act of 1987 is foundational in establishing the legislative groundwork for computer security policies in the United States.
