The importance of cyber security services for financial institutions

The financial sector is one of the most targeted industries for cyber attacks due to its critical data and financial transactions. The cost of implementing cyber security measures is far outweighed by the potential financial losses of a data breach. Engaging a managed cyber security service means having expert support ready to manage and monitor security incidents—because when it comes to cyber threats, it's not a matter of if, but when.

Your organisation’s resilience against threats like ransomware, phishing, and advanced persistent threats depends on the robustness of your cyber security strategy.

Employing an expert team dedicated to this purpose not only safeguards your financial data but also secures your reputation by ensuring the continuity of services to your clients.

What challenges does the financial services sector face when it comes to cyber threats?

The financial services industry, particularly in the UK, encounters significant cybersecurity challenges driven by both the complexity of digital transformation and the persistent threat landscape.

1. Increased attack surface due to digital transformation

The financial sector has aggressively adopted new technologies to improve efficiency and customer service, such as cloud computing and digital banking. However, this rapid digitalisation has also expanded the attack surface. Nearly a fifth of sensitive and restricted workloads in financial services are operated in the cloud, making them vulnerable to cyber threats. In fact, a considerable proportion of the sector acknowledges cloud services as the primary attack route.

2. The challenge of managing outsourced IT services

Outsourcing IT services, including cloud services and other third-party solutions, has become a strategic necessity for many financial institutions. While outsourcing offers cost and efficiency benefits, it introduces complexities in managing cybersecurity. The coordination required to ensure all third-party services comply with stringent security standards can be substantial, raising concerns about vulnerabilities in supply chains and third-party services.

3. Rise in cyber incidents and advanced persistent threats

The number of reported cyber incidents within UK financial services has seen a significant increase, with reports to the Financial Conduct Authority (FCA) jumping by over 50% in one year. These incidents often involve sophisticated cyber threats like ransomware and Advanced Persistent Threat (APT) groups. The sector's high-profile nature and the sensitive data it handles make it a prime target for such attacks.

4. Regulatory and compliance pressures

The regulatory environment for cybersecurity in financial services is stringent and evolving. UK financial institutions must navigate a complex landscape of regulations, including GDPR, PCI DSS, and various national standards set by the FCA. Compliance is not just about avoiding penalties but also about building trust with consumers and maintaining market integrity.

5. Adapting to emerging cybersecurity threats

Adapting to emerging threats requires not only technological solutions but also proactive threat intelligence and incident response strategies. The financial industry must continuously evolve its cybersecurity measures to address new threats. This involves significant investment in security systems and training staff to recognise and mitigate potential risks.

These challenges underscore the necessity for the financial services sector to enhance its cybersecurity strategies continuously. Emphasising risk management, regular security health checks, and a culture of security awareness will be key in safeguarding against current and future cyber threats.

What are the most common types of cyber attacks in the financial services sector?

Understanding the most common types of cyber attacks is crucial for developing effective defence strategies. Here are six prevalent cyber threats that financial institutions need to be vigilant about.

Phishing attacks

Phishing involves deceiving individuals into providing sensitive information or downloading malware by masquerading as a trustworthy entity in electronic communications.

• Who it affects? Employees and customers of financial institutions.
• How does it happen? Through emails, text messages, or social media messages that appear to be from legitimate sources.
• How do you prevent this attack? Implement multi-factor authentication, conduct regular security awareness training, and use email filtering and verification technologies.

Ransomware attacks

Ransomware is malicious software that encrypts a victim’s data, with the attacker demanding payment to restore access.

• Who it affects? IT systems of financial firms and their clients.
• How does it happen? Typically through phishing emails or exploiting network vulnerabilities.
• How do you prevent this attack? Keep all systems patched and updated, back up data regularly, and use advanced malware detection tools.

DDoS attacks

Distributed Denial of Service (DDoS) attacks aim to overwhelm systems, servers, or networks with a flood of Internet traffic, causing them to slow down or crash.

• Who it affects? Online services of financial institutions like online banking.
• How does it happen? By utilising compromised computer systems as sources of attack traffic.
• How do you prevent this attack? Use anti-DDoS hardware and software solutions and ensure redundancy in network infrastructure.

Insider threats

Insider threats come from individuals within the organisation who misuse their access to networks, systems, or data for malicious purposes.

• Who it affects? All levels of the organisation.
• How does it happen? Through malicious action or negligence by employees, contractors, or business associates.
• How do you prevent this attack? Implement strict access management and monitoring, conduct regular audits, and promote a culture of security awareness.

SQL injection

SQL Injection involves inserting or "injecting" a SQL query via the input data from the client to the application, often to corrupt database content, bypass login algorithms, or access data.

• Who it affects? Websites and databases of financial services firms.
• How does it happen? Through vulnerable website input fields where attackers can enter malicious SQL commands.
• How do you prevent this attack? Regularly update and patch databases, use prepared statements with parameterised queries, and conduct regular security testing of web applications.

Man-in-the-middle (MitM) attacks

In MitM attacks, the attacker secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other.

• Who it affects? Any financial transactions or data transfers occurring over insecure networks.
• How does it happen? Through compromised public Wi-Fi networks or malware-infected systems.
• How do you prevent this attack? Use strong encryption for data in transit, secure connections (HTTPS), and educate users about secure practices, especially on public networks.

By understanding and preparing for these common types of cyber attacks, financial services firms can better protect themselves and their clients from potential threats.
