A US politician, Representative Elijah Cummings, a Maryland Democrat, has publicly written to Sony Pictures and asked it to open up about the hacker attack on its networks.
Cummings wants the firm to open up so that the rest of the industry and security industry can learn from it, and so that the government can be better informed when it comes to making cyber security rules.
"The increasing number and sophistication of cyber attacks on both public and private entities pose a clear and present danger to our national security and highlight the urgent need for greater collaboration to improve data security," he wrote (PDF).
"Sony's knowledge, information and experience will be helpful as Congress examines federal cybersecurity laws and any necessary improvements to protect sensitive consumer and government financial information."
The letter asks Sony to describe all of the data breaches that it has endured over the past year, along with the date they happened, what happened, and how discovered and solved them.
Cummings also wants information on the types of data that have been breached, the number of employees and consumers who may have been affected, and the number of those who were notified.
Also demanded are forensic reports about the hacks, and the methods and systems that the firm has in place to deal with them.
Last week the firm was being praised for its openness about the attack. According to the FBI Sony's readiness to talk and share was key to its own studies into the assault, and helped it to peg North Korea as the likely source.
