Cyber security spending for critical infrastructure totalled US$41.76 billion globally in 2012, according to an ABI Research report.
The study Cyber Security Policy in Critical Infrastructure said the money was spent by nation states, non-governmental organisations, technical bodies, and private sector operators.
The report also pointed out that increased spending over the next five years will be driven by a growing number of policies and procedures in education, training, R&D, awareness programmes, standardisation work, and cooperation among other projects.
Energy, telecoms, healthcare, and transport systems and other critical sectors are making use of Internet connectivity and next generation technologies to boost productivity and improve efficiency. Protecting these networks from cyber threats requires a national approach.
The report said governments play a big role in ensuring the digital security of critical infrastructures. This requires accompanying technical efforts with policies in order to implement a coherent cyber security strategy across all sectors.
Currently, few nation states are prepared to counter a full-scale cyber attack on their critical infrastructure, noted ABI Research.
"Nation states need to focus on elaborating cyber security strategies as their critical sectors go online. Research and development of policies, regulation, cooperative schemes, public-private partnerships, guidelines, and best practices are all important elements in developing a robust strategy that can minimise cyber risks and strengthen infrastructures," said Michela Menting, senior analyst, ABI Research.
