DNS Filtering Bill Riles Tech Experts, Hacktivists
A bill moving through the U.S. Senate that would grant the government greater power to shutter Web sites that host copyright-infringing content is under fire from security researchers, who say the legislation raises “serious technical and security concerns.” Meanwhile, hacktivists protested by attacking the Web site of the industry group that most vocally supports the proposal.
Earlier this month, the Senate Judiciary Committee passed the Protect IP Act (PDF), a bill offered by its chair, Sen. Patrick Leahy (D-Vt.) that would let the Justice Department obtain court orders requiring U.S. Internet service providers to filter customer access to domains found by courts to point to sites that are hosting infringing content. The bill envisions that ISPs would do this by filtering DNS requests for targeted domains. DNS, short for the “domain name system,” transforms computer-friendly “IP addresses (such as 22.214.171.124) into words that are easier for humans to remember (typing krebsonsecurity into a browser brings you to 126.96.36.199, and vice versa).
