Why financial services must avoid cyber security attacks


Every day, the financial services industry processes millions of transactions, making it an attractive target for cyber criminals. In the past three years, there has been a threefold increase in cyber security breaches within these institutions. A report by the international legal firm RPC has shown a marked increase in incidents reported to the Information Commissioners Office (ICO), rising from 187 to 640. Specifically, there has been an increase in the number of reports from the pensions sector, which soared from six to 246.

Understanding the criticality of robust cyber security measures in financial services is essential. These institutions must remain vigilant and proactive in their defence strategies.

The high stakes for financial services

The high stakes for financial services in the context of cyber security are significant and multifaceted. They reflect the sector’s critical importance to the global economy, the sensitivity of the information handled, and the severe consequences of potential breaches. Here’s an elaboration on these stakes:

  1. Sensitive data at risk: Financial institutions store and process vast amounts of sensitive data, including personal identification information, financial records, transaction details, and investment strategies. A breach can lead to identity theft, financial fraud, and unauthorised access to accounts, causing severe financial and personal ramifications for customers
  2. Economic impact: The financial sector is a cornerstone of the global economy. Cyber attacks can disrupt trading, affect markets, and lead to substantial financial losses. The stability of financial institutions is crucial for economic confidence; any sign of vulnerability can lead to broader economic repercussions
  3. Trust and reputation: Trust is the bedrock of the financial industry. Clients need to believe that their assets and information are secure. A cyber security incident can erode this trust, leading to customer attrition and a tarnished reputation. Rebuilding trust is a long, costly process; in some cases, the damage to the brand may be irreparable
  4. Regulatory and compliance penalties: Financial services are among the most heavily regulated industries. Regulations like GDPR in the EU and various compliance standards worldwide mandate stringent data protection measures. Non-compliance and breaches can lead to hefty fines, legal battles, and increased scrutiny from regulators, adding a significant financial burden on top of other breach-related losses
  5. Operational disruption: Cyber attacks can paralyse critical operational systems, disrupt services, and lead to significant downtime. For financial institutions, time is money; even brief periods of inactivity can result in substantial revenue loss and affect the market’s overall functioning
  6. Competitive disadvantage: A cyber attack can give competitors an edge in a highly competitive sector. Customers seeking stability and security might move their assets to perceived safer institutions, leading to a loss of business and market share for the affected organisation
  7. Innovation stifling: With the increasing threat of cyber attacks, financial services might become hesitant to innovate and adopt new technologies for fear of introducing vulnerabilities. This hesitation can hinder growth and the ability to stay competitive with emerging fintech solutions

The sector’s ability to manage these risks effectively is critical for individual institutions and the broader economic and social fabric.

Common cyber security attacks in financial services

Financial institutions face a myriad of cyber threats, some of these might be:

  • Phishing attacks, wherein fraudulent emails trick users into divulging sensitive information, are increasingly sophisticated
  • Ransomware, another prevalent threat, locks institutions out of their systems, demanding hefty ransoms
  • Distributed denial of service (DDoS) attacks overload systems, disrupting services and damaging customer relations

For instance, a prominent UK bank suffered a massive DDoS attack in 2019, leading to service outages and customer frustration, highlighting the vulnerability of even the most robust systems.

Consequences of cyber security breaches

The ramifications of a cyber security breach are far-reaching. Immediate financial losses from theft, fines, and remediation efforts are just the tip of the iceberg. The long-term reputational damage can lead to customer attrition and reduced business. Legal consequences, including lawsuits and regulatory fines, further compound the issue. The intangible loss of customer trust and confidence can be the most challenging to recover, underscoring the need for impeccable security measures.

Proactive measures to avoid cyber security attacks

Proactive measures to avoid cyber security attacks in the financial services sector involve a comprehensive and forward-thinking approach. Here are key strategies:

  1. Regular risk assessments: Conducting frequent and thorough risk assessments helps identify vulnerabilities and emerging threats, allowing institutions to bolster their defences proactively
  2. Employee training and awareness: Human error is a leading cause of breaches. Regular training sessions on security best practices, recognising phishing attempts, and safe data handling can significantly reduce risk
  3. Robust security protocols: Strong security measures such as firewalls, encryption, multi-factor authentication, and intrusion detection systems can provide multiple layers of defence against attacks
  4. Continuous monitoring: Real-time monitoring of systems and networks can detect unusual activity early, enabling quick responses to potential threats
  5. Incident response planning: Having a well-defined incident response plan ensures that the institution can react swiftly and effectively to mitigate the impact of a breach
  6. Regular updates and patch management: Keeping all systems and software up-to-date with the latest security patches helps close vulnerabilities that attackers could exploit
  7. Secure development practices: Ensuring that any software developed or used by the financial institution follows secure coding practices to prevent common vulnerabilities
  8. Vendor risk management: Evaluating and monitoring the security practices of third-party vendors to ensure they don’t introduce new vulnerabilities
  9. Data protection strategies: Implementing data encryption, access controls, and regular backups to protect sensitive information
  10. Zero trust: The use of Zero Trust Network Access (ZTNA) will greatly protect your data through specific access permissions, and verification processes

By adopting these proactive measures, financial institutions can significantly enhance their resilience against cyber security attacks and protect their data, reputation, and the trust of their customers.

Stay ahead of cyber threats

The financial services sector faces significant risks from cyber security threats. Institutions must understand the nature of these threats and take comprehensive, proactive measures to safeguard their systems and data. The cost of prevention pales in comparison to the cost of a breach. As the digital landscape evolves, so must the strategies employed to protect it.
