Presidential Policy Directive 20 orders the creation of potential targets for Offensive Cyber Effects Operations by the NSA. According to the classified document, the "Government shall identify potential targets of national importance where [cyberattacks] can offer a favorable balance of effectiveness and risk . . ." The Directive was signed last October and EPIC immediately filed a Freedom of Information request seeking public release of the policy as it implicates the privacy of domestic communications. The NSA refused to release the Directive. The White House released a summary of the Directive, but failed to disclose information about the NSA's proposed cyberattacks. PPD-20 was made available to the public in a post to the Guardian by Glenn Greenwald. For more information, see EPIC: Presidential Directives and Cybersecurity, EPIC: EPIC v. NSA - Cybersecurity Authority and EPIC: Cybersecurity Privacy Practical Implications.
