Ravishankar Shukla University, Raipur, Chhattisgarh, India > Review Paper 2025 11 30 2026 06 20 This paper presents a comprehensive review of major network attacks and their mitigation strategies, emphasizing the growing threat of Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks. It examines essential cyber security principles—confidentiality, integrity, availability, authenticity, and non-repudiation—and outlines vulnerabilities, exploits, and classifications of active and passive attacks. The study reviews prominent attack vectors such as malware, ARP spoofing, IP spoofing, and Man-in-the-Middle (MITM) attacks, alongside conventional defense mechanisms including cryptographic algorithms, access control, and authentication protocols. Through an extensive literature survey, various mitigation frameworks based on statistical, cryptographic, and machine learning techniques are analyzed. The review identifies persistent challenges in detecting and mitigating DDoS attacks, particularly their distributed nature and stealth characteristics that evade conventional Intrusion Detection Systems (IDS) and firewalls. Findings highlight the necessity for adaptive, intelligent, and mathematically robust defense mechanisms, improved datasets, and standardized evaluation metrics to enhance resilience against evolving cyber threats.
