2. Status quo in Cloud Security

2.1 Significance of Cloud Security

Cloud security can be defined as the set of technologies, policies, and controls that help ensure data, applications, and infrastructure are secure and safe in the cloud. The increased adoption of cloud leads to new threats which attack the organizations such as data breaches, ransomware, and insider attacks.

2.2 Common Cloud Security Threats

Data Breaches: unauthorized access to the sensitive cloud data.

DDoS Attacks: flooding the cloud servers with malicious traffic.

Misconfigurations: incorrect configurations of security setup, which exposes vulnerabilities.

Insider Threats: attackers, who are employees or partners, abusing cloud access to do malicious things.

 

2.3 Ready-to-available Cloud Security Solutions

End-to-end encryption

Multi-factor authentication (MFA)

Zero-trust security models

Security information and event management (SIEM) solutions

However, with quantum computers becoming available, all these security solutions will soon be outdated.

3. How Quantum Computing Betrays Cloud Security

3.1 Cryptography Breakage

Encryption is the foundation of cloud security that protects secret information from unauthorized access. However, quantum computing will be a huge threat to the existing encryption algorithms: RSA (Rivest-Shamir-Adleman) Encryption; Elliptic Curve Cryptography (ECC); Advanced Encryption Standard (AES). A quantum computer can factor all these algorithms in minutes by using Shor’s Algorithm. Shor’s Algorithm is the algorithm designed to factor large prime numbers efficiently.
