2. Software Security
Users of IoT devices such as smart vehicles and industrial production systems must be protected from potential dangers due to security vulnerabilities. Therefore, security tests and code reviews should be done in software development processes. Also, security updates should be applied quickly.

3. Physical Access Control
Physical access is critical to the security of IoT devices. Only authorized persons should be allowed physical access and physical security measures such as security cameras should be used.

4. Separate Networks and Segmentation
IoT devices must be isolated using network segmentation and separate networks. This reduces the possibility of one device damaging the others.

5. Remote Access Control
IoT devices have remote access capability. However, these capabilities must be tightly controlled using secure channels specific to authorized users.

Examples of Security in Iot Systems

Smart Vehicle Security

Smart vehicles include many IoT devices to ensure the safety of drivers and passengers. For example, in-car entertainment systems increase occupant comfort while also making them vulnerable to attack. For the safety of these devices, the above technical precautions should be applied. Data encryption protects the confidentiality of driver and passenger data, while secure software development and update management ensures software security of vehicles. Physical access control prevents cars from being physically damaged or subjected to malicious tampering.

Intelligent Industrial Production Systems

Intelligent industrial production systems facilitate data collection while increasing automation in factories. These systems must provide security using industrial protocols and separate networks. In industrial production, while IoT devices transmit data within the facility, it is also important to ensure data protection and uninterrupted business processes. Physical access control and security cameras increase security in the factory environment, while separate networks and segmentation ensure devices are isolated and data protected.

IoT security can be achieved by combining technical measures and security principles. Each application domain should consider its own security requirements and threat profiles and implement appropriate technical measures. In this way, we can safely benefit from the advantages of IoT technology.
