Article 26Advanced testing of ICT tools, systems and processes based on TLPT

1. Financial entities, other than entities referred to in Article 16(1), first subparagraph, and other than microenterprises, which are identified in accordance with paragraph 8, third subparagraph, of this Article, shall carry out at least every 3 years advanced testing by means of TLPT. Based on the risk profile of the financial entity and taking into account operational circumstances, the competent authority may, where necessary, request the financial entity to reduce or increase this frequency.

2. Each threat-led penetration test shall cover several or all critical or important functions of a financial entity, and shall be performed on live production systems supporting such functions.

Financial entities shall identify all relevant underlying ICT systems, processes and technologies supporting critical or important functions and ICT services, including those supporting the critical or important functions which have been outsourced or contracted to ICT third-party service providers.

Financial entities shall assess which critical or important functions need to be covered by the TLPT. The result of this assessment shall determine the precise scope of TLPT and shall be validated by the competent authorities.

3. Where ICT third-party service providers are included in the scope of TLPT, the financial entity shall take the necessary measures and safeguards to ensure the participation of such ICT third-party service providers in the TLPT and shall retain at all times full responsibility for ensuring compliance with this Regulation.

4. Without prejudice to paragraph 2, first and second subparagraphs, where the participation of an ICT third-party service provider in the TLPT, referred to in paragraph 3, is reasonably expected to have an adverse impact on the quality or security of services delivered by the ICT third-party service provider to customers that are entities falling outside the scope of this Regulation, or on the confidentiality of the data related to such services, the financial entity and the ICT third-party service provider may agree in writing that the ICT third-party service provider directly enters into contractual arrangements with an external tester, for the purpose of conducting, under the direction of one designated financial entity, a pooled TLPT involving several financial entities (pooled testing) to which the ICT third-party service provider provides ICT services.

That pooled testing shall cover the relevant range of ICT services supporting critical or important functions contracted to the respective ICT third-party service provider by the financial entities. The pooled testing shall be considered TLPT carried out by the financial entities participating in the pooled testing.

The number of financial entities participating in the pooled testing shall be duly calibrated taking into account the complexity and types of services involved.

5. Financial entities shall, with the cooperation of ICT third-party service providers and other parties involved, including the testers but excluding the competent authorities, apply effective risk management controls to mitigate the risks of any potential impact on data, damage to assets, and disruption to critical or important functions, services or operations at the financial entity itself, its counterparts or to the financial sector.

6. At the end of the testing, after reports and remediation plans have been agreed, the financial entity and, where applicable, the external testers shall provide to the authority, designated in accordance with paragraph 9 or 10, a summary of the relevant findings, the remediation plans and the documentation demonstrating that the TLPT has been conducted in accordance with the requirements.

7. Authorities shall provide financial entities with an attestation confirming that the test was performed in accordance with the requirements as evidenced in the documentation in order to allow for mutual recognition of threat led penetration tests between competent authorities. The financial entity shall notify the relevant competent authority of the attestation, the summary of the relevant findings and the remediation plans.

Without prejudice to such attestation, financial entities shall remain at all times fully responsible for the impact of the tests referred to in paragraph 4.

8. Financial entities shall contract testers for the purposes of undertaking TLPT in accordance with Article 27. When financial entities use internal testers for the purposes of undertaking TLPT, they shall contract external testers every three tests.

Credit institutions that are classified as significant in accordance with Article 6(4) of Regulation (EU) No 1024/2013, shall only use external testers in accordance with Article 27(1), points (a) to (e).
