With the advancement of digital technology, cybersecurity threats have become increasingly complex and severe. The recent advancements in the field of cybersecurity and blockchain technology, such as Artificial Intelligence (AI)- based Intrusion Detection Systems (IDSs), zerotrust security models, blockchain-backed digital identity management, quantum-proof cryptography methods, and robust multi-factor authentication solutions are investigated in this work. It also examines blockchain-based smart contract vulnerability assessment, privacypreserving data sharing through blockchain, cybersecurity risks in 5G and beyond networks, ransomware detection and prevention techniques, and biometric-based cybersecurity mechanisms. This research highlights the importance of integrating advanced security frameworks to counter emerging threats and ensure a secure digital ecosystem.
