In today's hyper-connected world, implementing security in cyberspace has become a global strategic priority. As technology’s role in society increases, cybersecurity becomes an increasingly bigger challenge. In addition, the cyber threat landscape is evolving, with the emergence of new risks and the sophistication of existing threats. Cybercriminals are increasingly targeting specific sectors, such as energy, finance, government, and healthcare, to cause maximum disruption and financial gain or loss. In Spain, the successive editions of the National Report on the State of Security (INES) and the body of CCN-STIC security guides have resulted in greater accumulated experience in its application and better knowledge of the situation. The new National Security Framework 2022 stands as a pivotal platform, addressing cybersecurity in a manner intricately linked to digital transformation. This is achieved through a robust and consolidated regulatory framework, making it the most significant development in this field. In this sense, Royal Decree 311/2022 is a guiding light for security in the digital society. Its applicability to crypto-asset systems is crucial to building a reliable foundation in the new financial paradigm. It represents a reference framework, a robust framework for assessing and improving security in systems that handle crypto assets.
