Sockatume writes: The UK's information protection authority, the ICO, has fined Sony for failing to adequately secure the information of PlayStation Network users. The investigation was triggered by a 2011 security breach, during which personally identifying information (including password hashes) was recovered from a Sony database where it had been stored without encryption. In the ICO's view Sony's security measures were inadequate, and the attack could have been prevented. The £250,000 (ca. $400,000) fine, the largest the ICO has ever imposed, is equivalent to a few pennies per affected user. Sony disagrees with the ICO's decision and intends to appeal.
