1. Secure Device Authentication 🔐
Always use strong authentication mechanisms (e.g., unique credentials, multi-factor authentication) for IoT devices. Avoid default passwords and implement role-based access control (RBAC) where necessary.
2. Regular Firmware Updates 🔄
Keep IoT firmware up to date to patch vulnerabilities. Automate updates where possible, but ensure compatibility with existing systems.
3. Data Encryption 🔒
Encrypt data both at rest and in transit using protocols like TLS 1.2 or higher. This protects sensitive information from interception or unauthorized access.
4. Network Isolation 🌐
Segment IoT devices on a separate network (e.g., VLAN) to limit exposure to other systems. Use firewalls to restrict traffic between networks.
5. Monitor and Log Activity 📊
Enable logging for all device interactions and use SIEM tools to detect anomalies. Regularly review logs for suspicious behavior.
6. Physical Security 🔒
Secure IoT devices physically to prevent tampering. Use tamper-evident seals and restrict access to critical hardware components.
