6-2 Activity: Errors in IoT Design SNHU IT 423: Computing as a Service

Paper Title in Bold at the Top of Page 2 Three errors I have identified in the architectural diagram are that all IoT devices are running on the same single network, the second error is that the IoT devices are able to access the internet using the wireless access point, and the third error is that there is no firewall to protect the IoT devices from malicious attacks. All the IoT devices are to blame for this error. The wireless access point connects all the IOT devices to the workstations/devices, making each device vulnerable. Anyone without access to this information can easily obtain sensitive information through this method. To protect all data, this design error needs to be redesigned and a firewall should be implemented to keep the workstations/devices data from the IoT devices. The firewall should be configured to block IoT devices from accessing the workstations/devices. The system can continue to function without addressing error, but it will be more vulnerable to attacks. The IoT devices can access workstations/devices, which may contain sensitive and valuable data, without the firewall. To prevent this, the firewall should be properly configured and monitored to ensure that all IoT devices are blocked from connecting to the workstations/devices. A router is the best solution to ensure all data can be protected on the IoT wireless network and the workstation wireless network. The router should only allow access to IoT devices and block access to the workstation network. This will stop data leaks from the IoT network into the workstation network. By encrypting the IoT network's data, it addresses the CIA threat. It also ensures that the data is not accessible or vulnerable to attack from external networks. It prevents unwanted actors from accessing the IoT network. A good solution is to isolate the IoT devices from the rest of the network so that they are all connected to the same one. By creating a separate network dedicated to your IoT devices, you can safeguard your main network against IoT threats (Anderson, 2023). Isolating IoT devices

will ensure they are only connected to the devices they need to communicate with. This way, the devices will not have access to the public internet, and threat actors will not be able to access the data from the network. It provides a secure environment for data so there are no issues with confidentiality, integrity, or availability. To solve the problem of not having a firewall, it is a good idea to install and configure one properly. A firewall is a network security device that keeps out unauthorized users and hackers (Maxwell, 2022). It should be set to allow only the necessary traffic and block any other traffic. This solution addresses issues with the CIA triad within the system by providing an extra layer of protection. This makes it more difficult for attackers to gain access to the system and reduces the risk of a data breach. Additionally, a firewall can detect and block unwanted traffic. References Anderson, M.
