Introduction

In 2018, the Financial Stability Board (FSB) developed the Cyber Lexicon to support the work of the FSB, the standard-setting bodies (SSBs) and other international organisations to address cyber security and cyber resilience in the financial sector. Following its initial publication in 2018, the Cyber Lexicon was updated in 2023 to ensure it remained current with the evolving cyber landscape and development of information technology. [The exercise to update the Cyber Lexicon was conducted as part of the FSB’s work to achieve greater convergence in cyber incident reporting.] The same criteria for inclusion and exclusion used in the creation of the lexicon in 2018 (see Section 2) were applied to ensure continued consistency in content. In updating the lexicon, the FSB reviewed over 80 terms proposed by the private sector and national authorities for inclusion, and also considered feedback from a public consultation and via engagement with the private sector.
