15. Zero Trust Security: Zero Trust Security is a security model that assumes no trust in any user or system, both inside and outside the network perimeter. It requires strict access controls, continuous monitoring, and least privilege principles to protect against insider threats and external attacks.

16. Artificial Neural Networks (ANNs): Artificial Neural Networks are computational models inspired by the human brain's neural networks. They consist of interconnected nodes (neurons) that process information and learn from data to make predictions or decisions.

17. Reinforcement Learning: Reinforcement learning is a machine learning technique that enables an agent to learn through trial and error by interacting with its environment. It is used in cybersecurity to train AI models to make decisions in real-time based on feedback received from the environment.

18. Natural Language Processing (NLP): Natural Language Processing is a branch of AI that focuses on enabling computers to understand, interpret, and generate human language. It is used in cybersecurity for tasks such as text analysis, sentiment analysis, and threat detection.

19. Explainable AI: Explainable AI is an approach to AI development that aims to make AI models transparent and interpretable. It enables users to understand how AI algorithms make decisions and provides insights into the reasoning behind their outputs.

20. Federated Learning: Federated learning is a distributed machine learning approach that allows multiple parties to collaborate on training a shared model without sharing their data. It is used in cybersecurity to protect sensitive data while leveraging collective intelligence for model training.

21. Homomorphic Encryption: Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without decrypting it. It enables secure data processing in the cloud while maintaining data privacy and confidentiality.
