The Importance of Threat-Led Penetration Testing for DORA Compliance

As cyber threats continue to grow in sophistication and frequency, financial institutions must go beyond just responding to incidents. They need to proactively assess their resilience against real-world attacks.

This is why the European Union introduced the Digital Operational Resilience Act (DORA), which mandates certain financial organizations to conduct regular penetration testing based on real-world threats — Threat-Led Penetration Testing (TLPT).

What is Threat-Led Penetration Testing?

Threat-Led Penetration Testing (TLPT) is a cybersecurity testing methodology that simulates real cyberattacks using current threat intelligence. Unlike traditional penetration tests, which typically follow a predefined set of scenarios and tools, TLPT focuses on the latest tactics, techniques, and procedures (TTPs) used by threat actors. By doing so, TLPT provides a more accurate and effective assessment of an organization’s cybersecurity posture against evolving real-world threats.

The Role of DORA in Cybersecurity

The Digital Operational Resilience Act (DORA), part of the European Union’s efforts to strengthen the financial sector's resilience to cyber threats, requires that critical financial entities conduct regular security tests to ensure their systems can withstand sophisticated attacks. DORA mandates the adoption of TLPT as part of a comprehensive cybersecurity strategy to safeguard critical infrastructure and sensitive data.

Why DORA Requires Threat-Led Penetration Testing

1. Proactive Threat Identification

DORA stresses the importance of anticipating emerging threats and vulnerabilities before they can be exploited. TLPT, through its use of up-to-date threat intelligence, allows organizations to identify weaknesses that traditional tests might miss, especially those that attackers could exploit in the real world.

2. Simulation of Real-World Attacks

By using techniques mimicking actual cybercriminal behavior, TLPT simulates scenarios that reflect the tactics and strategies currently used by malicious actors. This results in more relevant insights, allowing organizations to focus their remediation efforts on threats that matter most.

3. Regulatory Compliance

For organizations covered by DORA, non-compliance with penetration testing requirements could result in legal and financial consequences. TLPT ensures that these organizations meet the specific cybersecurity expectations set forth by the EU, making it an essential component of their compliance efforts.

4. Enhanced Security Posture

TLPT provides actionable insights into an organization's vulnerability to the most pressing cyber threats. By adopting TLPT as part of their cybersecurity strategy, financial institutions can bolster their defenses, improve their incident response capabilities, and ensure better protection of customer data and assets.

How is Threat-Led Penetration Testing Different from Normal Penetration Testing?

While both Threat-Led Penetration Testing (TLPT) and traditional penetration testing aim to assess and improve an organization’s security, they differ in approach, focus, and the outcomes they deliver. Here's how TLPT stands apart from normal penetration testing:

1. Approach

• Normal Penetration Testing: In traditional penetration testing, ethical hackers follow predefined methods and tools to identify vulnerabilities within an organization’s systems. The scope is often outlined beforehand, and testing generally focuses on a set of known risks.

• Threat-Led Penetration Testing: TLPT, on the other hand, takes a more dynamic approach. It leverages real-time threat intelligence and adapts to the tactics, techniques, and procedures (TTPs) used by active threat actors. The testing scenarios are more aligned with actual attack methods currently being used in the cyber threat landscape, making it more relevant and realistic.

  
  

2. Focus

• Normal Penetration Testing: The focus is usually on discovering vulnerabilities across the organization’s infrastructure — such as networks, applications, and endpoints — without necessarily considering the broader threat landscape or the specific tactics attackers might use.

• Threat-Led Penetration Testing: TLPT focuses specifically on replicating the behavior of real-world attackers, using current cyber threat intelligence. It simulates the full kill chain of a cyberattack, from initial compromise to data exfiltration or system manipulation, thereby offering a comprehensive view of how attackers might target the organization.

3. Realism

• Normal Penetration Testing: Traditional pen testing may not always consider the most up-to-date threat vectors or the techniques that the latest threat actors are using. It might not simulate the type of advanced, persistent attacks that are increasingly common in today’s cyber landscape.

• Threat-Led Penetration Testing: TLPT uses threat intelligence to closely mimic advanced cyberattacks, providing a more realistic and thorough evaluation of how well the organization can withstand sophisticated, real-world attacks. This is a direct response to the evolving nature of cyber threats, where attackers are constantly adapting their strategies.

4. Outcome and Remediation

• Normal Penetration Testing: The result of a traditional pen test is typically a report detailing vulnerabilities and weaknesses found in the system, along with suggestions for remediation. While useful, this report may not prioritize the most critical vulnerabilities in terms of how likely they are to be exploited by real attackers.

• Threat-Led Penetration Testing: The outcome of TLPT goes beyond identifying vulnerabilities — it provides a comprehensive view of the organization’s risk exposure to real threats. It helps prioritize vulnerabilities based on how likely they are to be targeted by threat actors. This enables the organization to focus on the most pressing risks, improving both short-term defenses and long-term resilience.

5. Compliance and Industry Relevance

• Normal Penetration Testing: While normal penetration testing is widely used in various industries for compliance and security assessments, it may not fully meet the requirements of more specific regulations like DORA, which demand testing based on current threat intelligence.

• Threat-Led Penetration Testing: TLPT is specifically designed to address modern regulatory demands like those in DORA, which require financial institutions to conduct penetration tests based on current threats. TLPT helps ensure compliance with regulations that emphasize proactive security measures tailored to the evolving threat landscape.

Here is a comparative table highlighting the key differences between Threat-Led Penetration Testing (TLPT) and normal Penetration Testing.

In summary, while both types of penetration testing are valuable, Threat-Led Penetration Testing provides a more up-to-date, realistic, and comprehensive evaluation of an organization's security, aligned with the tactics of actual cyber adversaries. It’s this focus on real-world attack simulations and threat intelligence that makes TLPT a crucial element for organizations looking to stay ahead in the ever-changing cyber threat environment.

Threat-Led Penetration Testing is no longer just a best practice — it is a critical component of compliance with DORA. As cyber threats evolve, so must the tools and strategies used to test and protect systems. TLPT helps organizations identify vulnerabilities in the context of real-world attack methods, ensuring a more resilient and secure infrastructure. For financial institutions striving to meet regulatory requirements and safeguard their operations, adopting TLPT is a necessary step toward building a robust cybersecurity framework.
