+**Network Security:**\\
+Network security in IoT databases protects the data flow between IoT devices and their associated databases from unauthorised access and cyberattacks. This involves securing communication protocols with encryption standards such as TLS, implementing firewalls to filter traffic, and utilising virtual private networks (VPNs) for remote access. Network segmentation can isolate IoT databases from other parts of the system, reducing the risk of lateral movement during a breach. Real-time monitoring and intrusion detection systems (IDS) ensure anomalies in traffic are promptly identified and mitigated.
+**Access Management:**\\
+Access management for IoT databases ensures that only authorised users, devices, and applications can access stored data. This is critical in preventing unauthorised manipulation or theft of sensitive information. Multi-factor authentication (MFA), role-based access control (RBAC), and device-specific tokens are commonly employed to regulate access. Additionally, periodic audits of access logs can reveal patterns indicative of suspicious activities, enabling proactive security measures.
+**Threat Management:**\\
+Threat management in IoT databases focuses on detecting, mitigating, and preventing risks such as malware, ransomware, or insider threats that could compromise data integrity and availability. Organisations can use advanced threat detection tools powered by machine learning to identify unusual patterns in database queries or access attempts. Automated threat response mechanisms, such as isolating compromised database nodes, further enhance protection. Regular vulnerability assessments and patch management ensure the database remains resilient against emerging threats.
+**Data Protection:**\\
+Data protection in IoT databases ensures that sensitive information remains secure throughout its lifecycle—collection, storage, processing, and deletion. Encryption techniques like AES safeguard data at rest, while TLS protects data in transit. Secure backup strategies and redundancy mechanisms help mitigate the impact of data loss or corruption. Compliance with data protection regulations, such as GDPR or CCPA, ensures that personally identifiable information (PII) from IoT devices is handled responsibly. Data masking and anonymisation techniques are often employed to enhance privacy and limit exposure in case of a breach.

 IoT devices generate vast amounts of data, often in real-time, encompassing sensitive information such as personal identifiers, health records, location data, and industrial metrics. Ensuring the security of databases storing this data is critical for several reasons:
