How Quantum Computing Impacts Cyber Security

Cybersecurity confronts several challenges in the current and upcoming decades. Quantum computing might be one of these challenges that is the worst. Usually, cybersecurity provides techniques, standards, policies, configurations, and recommendations to protect classical system assets. According to the CIA triad (Confidentiality, Integrity, and Availability) fundamentals and the current domain structures used in the classical IT infrastructure systems, vulnerability may occur at any time and place, where several technical and non-technical foundations have been breached aggressively during the past ten years. These breaches are based on classical weaknesses, whether in the offensive or defensive platforms. Quantum computing might be the solution to these problems. However, quantum computing will be a part of the problem, since quantum usage requires a variety of devices, software, applications, and policies. Most of these requirements are still not ready to be approved or even exist. This paper focuses on the logical readings of the near future when quantum computers become available or before. In addition, some advantages and disadvantages are concluded to declare some circumstances that probably face cybersecurity in the upcoming decades.
