Sony hacking

This refers to the report, "Sony releases Kim comedy online" (Dec. 25). It is good that Sony has decided to release the movie. However, the hacking of this Japanese company's website by North Korean hackers, as alleged in the media reports, is a serious issue. Was Sony not prepared or was its cyber defense weak? How to avoid such future attacks? All these issues need to be considered and preventive steps should be taken. Japanese businesses need to fortify their cyber defenses. We should not forget that Japan has space technology.
