Provide identity to a device: View IoT devices not as some technology item but as an important user who has an access to sensitive information. This assumption will help identify and provisioning the devices to help monitor and manage them thoroughly on the network cycle.
Enable device governance: with giving an identity to each device make sure to apply policy-based authentication and access control. It will help in easy to the deployment of any IoT device. Keep in mind that these devices are channelized between the internet and your environment making them vulnerable for easy attack vector and unauthorized users. Device authentication and access should scrutinize and revisit during software updates, bug fixes, new firmware, routine maintenance and diagnostic improvements.
The principle of least privilege: remember to provide minimum access to data and systems in order to limit the access of IoT devices. Firewalls and permissions to safeguard will help in protecting dives against unauthorized devices and stops them in accessing privileged information. Remember, the less access you give an IoT device, the less damage to the information and business.
Manage passwords of devices: IoT devices have passwords to provide verification into systems, files and data. Always consider having a periodic reset and multifactor of passwords. Remember that these passwords must be updated with close management for the protection of vital information.
Monitor device frequently: remember to monitor the devices 24×7 to help in the identification of unusual activity and check for necessary patch updates. Always confirm device to the right network segment. Be cautious, Machines are easily analysed with abnormal behaviour when providing a giveaway to an unauthorized user and controlling it.
These few steps will not only protect your devices but also help in the smooth and swift functioning of the IoT devices. This will have a great impact on the revenue and security of your businesses as well.
