Abstract

The advent of quantum computing creates significant problems for the older cybersecurity standards. Quantum computing is a threat to conventional encryption, such as RSA and ECC. The constantly increasing rate of cyberattacks and the increasing quantum capacity warrant organizations' restructuring to ensure data security. This paper looks into the issue of cybersecurity vulnerabilities in the quantum age and assesses the impact of investment, regulations, and quantum-safe protocols on resilience to cybersecurity vulnerabilities. The analyzed secondary data (2011-2024) included the number of cyberattacks, the increase in the adoption of encryption, quantum-safe deployment, the amount of investments, and the regulatory index. Public report studies (ENISA, NIST, IBM, WEF) were used to discern trends in quantum threats and countermeasures with descriptive analysis. The cyberattacks were inconsistent, and the quantum threat scores rose progressively over the years (53.3 to 96.7). The percentage of encryption ranged between 55 and almost 90, whereas a quantum-safe protocol increased slowly (38 to 77). Investment in cybersecurity rose by nearly half, and resilience scores increased by 28.3 points to 97.8. The results implied that resilience has a positive correlation with the increased level of investments and regulations. Quantum-safe deployment remains below the quantum threat index; however, this suggests a faster need to migrate to post-quantum algorithms. Developing countermeasures to quantum threats with investment in post-quantum cryptography, creating awareness, and robust laws and rules need to be among the priorities of organizations for future security.
