Firewalls are security devices or software that are used to monitor and control incoming and outgoing network traffic, based on a set of predefined security rules.
Firewalls are essential security measures for IoT devices and networks. They are hardware or software devices that monitor and control incoming and outgoing traffic based on predefined security rules, such as blocking traffic from suspicious IP addresses or limiting access to certain ports. Firewalls are crucial for protecting IoT devices and networks from cyber attacks, such as distributed denial of service (DDoS) attacks, malware, and other cyber threats.In the IoT industry, firewalls are used to secure a wide range of devices, from smart home appliances to industrial control systems. They play a critical role in ensuring the confidentiality, integrity, and availability of sensitive data and applications, as well as protecting against unauthorized access and data breaches. Implementing effective firewall security requires careful planning and configuration, including regular updates and maintenance to stay ahead of evolving cyber threats
