The cyber security, resiliency and accountability of IT systems at financial services organizations is rarely out of national headlines. Firms that operate in the financial space hold extremely sensitive data, so therefore attackers usually consider the effort and risk of attacking them worth the potential reward.

This recent article in the Financial Times mentions some of the interesting steps that organizations are taking in order to drive up the operational costs of would-be attackers, as well as some of the figures involved in the investment in cyber security by banks and other financial sector businesses.
