Your network security is at risk due to an insecure IoT device. How will you prevent a potential data breach?

To prevent a data breach from an insecure IoT device, take a targeted and layered defense approach: Isolate the Device: Segment it on a separate VLAN to limit access to sensitive systems. Change Default Credentials: Replace factory usernames and passwords with strong, unique ones. Disable Unused Features: Turn off services and ports not in use to reduce the attack surface. Enable Firmware Updates: Regularly patch the device to fix known vulnerabilities. Monitor Device Behavior: Use network monitoring to detect unusual traffic or anomalies. Limit Data Access: Restrict what the device can access or transmit within your network. Review Vendor Security: Ensure future IoT purchases meet strict security standards.

You must conduct an inventory audit in order to prevent potential data breaches. This is so that you would know what IoT devices there are. You need to conduct inventories on new devices as well as existing ones. This is so that you would know which one could pose a risk to your network. You must include any IoT devices including CCTVs, smart watches and any devices linked to your system besides the regular computers and phones. This is because anything that's linked could pose a threat to your network.

As mentioned it is due to the IoT device I would likely to remove it and also it's connections with my network to ensure the security of network as a first step without any hesitant.

To prevent a potential data breach, you need to make sure that you update all of the IoT devices regularly. This is to ensure that they are always equipped with the highest level of security features. You must make sure that you set a schedule to update these devices. This is so that you would know when you need to update them. If you really don't have the time to do it, you could schedule the updates. This is to ensure that it will be updated even if you don't have the time to do so.

You need to implement strong authentication if you want to prevent a potential data breach. This is because this is needed to prevent unauthorized access. You must implement multi-factor authentication or two-factor authentication. This is to ensure that only authorized users have access to your network. You need to make sure that all of your IoT devices are using strong authentications. This is because one device could already pose a threat to your network.

You could conduct network segmentation in order to prevent a potential data breach. This is because if they aren't separated, they could affect others that are connected to them. You should identify which IoT devices are at risk of data breaches. This is so that you would be able to secure these devices the most. You should then isolate devices that have experienced data breaches before. This is so that you would know that you need to monitor these devices regularly.
