An enterprise can safeguard its Internet of Things systems by taking a number of procedures, including the following:  Integrate security from the beginning of the design process and make security the default setting.  To protect the devices that make up the internet of things, implement public key infrastructures and use 509 digital certificates.  Use application performance indicators to preserve data integrity.  Endpoint hardening should be implemented, such as making devices tamper-proof or tamper-evident, and it should also be ensured that each device has a unique identity.  Employ sophisticated cryptographic techniques in order to encrypt data both while it is in transit and while it is stored.  Protect networks by turning off port forwarding, shutting ports that are not being used, banning IP addresses that are not allowed, and ensuring that all network software and equipment is up to date. In addition, instal antimalware, firewalls, intrusion detection systems, intrusion prevention systems, and any other protective measures that may be required.  Identify and take inventory of IoT devices connected to the network by using the methods for controlling network access.  Utilize distinct networks for Internet of Things (IoT) devices that connect directly to the web.  Employ security gateways so that they may act as go-betweens for the Internet of Things devices and the network.  Always be sure to instal the latest updates and patches for any software that is a part of the Internet of Things system or that is used to manage IoT components.  It is important to provide anyone who engage on the Internet of Things system in any capacity, whether they are planning, implementing, creating, or managing, with security training and instruction.
