Social Network Security and Cybersecurity: A State-of-the-Art Survey of Challenges and Emerging Threats

Social networks have transformed the way individuals communicate, share information, and build digital communities. However, this widespread connectivity has introduced significant cybersecurity concerns that threaten user privacy, data integrity, and system resilience. This state-of-the-art survey explores the evolving landscape of social network security, identifying core challenges such as account hijacking, misinformation dissemination, malware propagation, identity theft, and AI-driven threats. The paper critically analyzes existing security frameworks, emerging attack vectors, and current defense mechanisms deployed across various platforms. In addition, it highlights the role of artificial intelligence, blockchain, and regulatory policies in shaping the future of secure social networking. By synthesizing recent advancements and ongoing research, this survey aims to provide a comprehensive understanding of the current threat environment and proposes a strategic outlook toward mitigating emerging risks in social network ecosystems.
