Cyber security The consequences of cyberattacks can be considerable. What we are now witnessing is probably just the beginning. We must find a suitable way to mitigate risk, without making our systems needlessly expensive. Cyber-security challenges are among the most significant challenges to our payment system. Without an efficient defence system, trust in the system can be undermined over time. For its part, Norges Bank is devoting considerable resources to securing its systems, oversight of activities and implementing measures to protect against cyber attacks. As part of oversight and supervision, we will increase our monitoring of cyber-security risks in the payment system. This requires cooperation, both nationally and internationally, to identify and combat cyberattacks. Nationally, this takes place through, for example NorCERT, part of the Norwegian National Security Authority (NSM), and for the financial sector through the Norwegian Financial Sector Cyber Security Center (FinansCERT) under Bits. The Nordic financial sector has established 3/5  BIS central bankers' speeches  Nordic Financial CERT as an extension of the Norwegian FinansCERT. The need for cooperation does not stop at a Nordic level. The challenges are international, and are shared by private financial undertakings, their service providers and subcontractors and authorities in many countries. Measures to promote cyber security are technically complicated and require specialist expertise. But it is management and boards of directors in institutions and companies that have the final responsibility and decide strategy and resource use. This responsibility cannot be delegated or outsourced to others. Owners and managers must be aware of their ultimate responsibility.

Bank deposits refer to money that is issued by, and is a claim on private banks. Each time a bank extends credit, new money is created. Bank deposits now account for 98 percent of the broad money supply (M3). The increasing use of new payment methods, such as mobile payment solutions, suggests that this percentage will continue to rise. We have to ask ourselves: should we allow private solutions to compete freely in developing means of payment, or must the authorities play a role? The crucial factor is whether solutions based on private money deliver the characteristics the payment system should have. The system must be able to channel payments swiftly, safely, at low cost and in a user-friendly manner. The means of payment itself – our money – must be universal, because money is only useful if it is widely used. This requires trust. Deposit guarantee schemes and banking regulation promote trust in banks’ deposit money. Trust is also underpinned by being able to convert to another secure alternative, ie cash. Norges Bank assists private operators in implementing faster and safer payments. We cooperate with other authorities to oversee and supervise the payment infrastructure to ensure robustness and efficiency. Privacy rules prevent unauthorised access to payment information. But there are some characteristics deposit money lacks. Nor is direct and immediate settlement between two parties, without the involvement of a third party, possible without cash. The system is vulnerable to advanced attacks.
