There are no publicly available procedures on how a U.S. company that wants assistance from the U.S. government in countering an attack (such as from NSA) could request it, and there is scant legal statutory authority for the government to provide such assistance. ( National Security Directive 42 provides a narrowability for NSA assistance to government contractors).
