A Comparative Study Between Traditional And Modern Cyberattack Types and Cryptographic Defense Mechanisms

Abstract

The development of digital technologies is occurring at such a rapid pace that the complications and complexities of attacks are becoming more frequent. As a result, cybersecurity is becoming a major problem for information systems. This review gives a comparative analysis of the traditional cyber-attacks and modern cyber-attacks and the role of cryptography in security in detail.   Malware and virus threats, phishing (social engineering) and fraud, network attacks, Denial-of-Service (DoS/DDoS), insider threats are some of the attacks that are dealt with here. Moreover, the study looks into the evolution of modern cyber threats such as Advanced Persistent Threats (APTs), Ransomware-as-a-Service (RaaS), zero-day exploits, AI-powered phishing, cloud security attacks, and IoT attacks and their growing sophistication, persistence, and ability to circumvent standard security mechanisms. Moreover, this review not only scrutinizes classical and symmetric techniques but also asymmetric and hybrid techniques with post-quantum cryptography to combat possible threats. In other words, it analyses a significant role of cryptography to secure digital assets.  The characteristics of cyberattacks and cryptographic techniques are shown in tabular form for understanding of their strengths, limitations and applications. In addition, the document will explore best practices on cyber defense and promising future researches such as AI-based security, Zero Trust Architecture, cloud security and quantum-resistant crypto. The findings suggest the need for a combination of mean, advanced cryptographic techniques, smart threats detection systems, continuous monitoring and able security management for the confidentiality, integrity and availability of digital information as cyber threats become more sophisticated. This review is a comprehensive reference for researchers, practitioners, and cybersecurity professionals on the new cyber threats and the significance of cryptography in today’s cybersecurity.
