Digital banking offers increased convenience and accessibility. However, this growth also exposes banks to heightened cybersecurity risks. Protecting data and information is crucial to maintaining customer trust and preventing financial loss.
Cybercrime poses a significant threat to the digital banking industry. According to Cybercrime Magazine, cybercrime costs will increase by 15% over the next five years and reach $10.5 trillion by 2025. These attacks target sensitive information and funds, causing substantial damage to banks.
To mitigate these risks, banks must implement robust cybersecurity measures to safeguard digital systems and data.
1. Strong Authentication
The Payment Services Directive (PSD2) mandates strong customer authentication (SCA) to reduce fraud and enhance online payment security. This directive imposes specific requirements on market participants to meet new obligations. The European Banking Authority (EBA) developed regulatory technical standards (RTS) based on the Commission’s authority under PSD2.
The RTS aims to protect consumers and create a level playing field within the evolving financial technology market. To achieve this, the RTS establishes security measures for payment service providers — including banks and other financial institutions — when processing payments or offering payment-related services.
2. Encryption
Unencrypted data is a common cyber threat. Hackers can easily access this data type and give severe consequences for banks. According to Statista, the average cost of a data breach worldwide is $4.45 million dollars. However, data breaches not only cause substantial financial loss for recovery and ransom payments but also damage a bank’s reputation.
To prevent these issues, all digital banking data must be encrypted. This safeguards information and makes it difficult for cybercriminals to access even if stolen. Encryption transforms data into a coded format that requires a specific key to decipher. Only individuals with the correct key can view the original data.
Encryption involves using an algorithm and a key to convert plain data into encrypted data. The original data can only be recovered by decrypting the ciphertext with the correct key.
3. Regular Cybersecurity Audit
A security audit is a thorough examination of an organisation’s IT infrastructure. This process verifies the effectiveness of security policies and procedures. Security audits assess how well an institution’s cybersecurity program operates. This includes reviewing policies, testing controls, and checking compliance with industry standards and regulations.
Banks and financial institutions face increasingly complex cyber threats. Regular security audits help identify vulnerabilities in systems. By discovering weaknesses, banks can strengthen defences with firewalls, antivirus, and antimalware software. A cybersecurity audit should be conducted by an independent expert to ensure objectivity.
4. Employee Training
The World Economic Forum reports that 95% of cyberattacks involve human error. This means hackers often exploit employee mistakes. They use tactics like phishing to deceive employees into revealing sensitive information. This can lead to data breaches and financial loss. For example, employees might click on malicious links, disclose confidential data, or leave devices unattended.
Therefore, bank employees must have training to recognize that cyberattacks are a constant threat. Moreover, the consequences of a breach can be severe for employees, customers, and the bank’s reputation. Cybercriminals operate in a lucrative industry, for that reason, it is imperative to equip employees with the knowledge to safeguard against these threats.
5. Incident Response Planning
An incident response plan is a formal document approved by bank leadership to guide the organisation before, during, and after a potential or confirmed security incident. The plan aims to reduce the impact of security events, limiting operational, financial, and reputational damage.
A successful incident response plan should be established before a security attack occurs and assigned to specific team members. IBM research shows companies with well-developed and tested response plans save an average of $2.66 million compared to those without such protocols.
To create an effective incident response plan, banks can reference established frameworks. For specific incident handling steps, The National Institute of Standards and Technology’s SP-800-61 and SANS’s Incident Handlers Handbook provide detailed blueprints. Aligning the incident response plan with these resources ensures a focused and effective approach to managing cybersecurity incidents.
Importance of Cybersecurity Measures
The increasing reliance on digital platforms exposes individuals and organisations to growing cybersecurity risks. Malicious actors exploit security weaknesses to steal personal information and compromise digital assets. Forbes reported a staggering increase in cyberattacks in 2023, impacting over 343 million people, with data breaches soaring by 72 percent from 2021 to 2023. These striking figures highlight the urgent need for state-of-the-art cybersecurity in digital banking.
