You are working on an IoT pilot project that involves collecting temperature and humidity data from a network of temperature and humidity sensors. There are three types of sensors. Temperature sensor type T-U1, temperature type T-E2, and humidity sensor type H-S1. Temperature sensor type T-U1 measures temperature to the nearest ºF, temperature sensor type T-E2 measures temperature to the nearest 0.1 ºC and humidity sensor H-S1 measures humidity levels to the nearest %. Each sensor sends a message to a central server in the format as shown in the following.
Write a regular expression that can be used to determine the validity of received messages.
Demonstrate the effectiveness of the proposed regular expression using
www.regex101.com or any other regular expression testing tools using appropriate test data. Include screenshots of your testing and provide explanation on the test results.
6 months after the project, it was reported that environmental data was stolen from the network while it is being transmitted from the sensors to the server. The management has decided that encryption of data-in-motion should be implemented. Recommend an encryption type (symmetric or asymmetric) and assess the merits of your recommendation.

One month after the launch, the ride sharing application was hacked when hackers successfully stole the system administrator password via phishing. As a result, the personal details of users were stolen and released on the Internet onto a Google document by hackers. As this Google document was shared to the public with full permission, some of the users’ details were modified or deleted. Subsequently, this document was deleted by Google upon request by Ubber. Evaluate the impact of this hacking incident to Ubber using the CIA model.
Suggest FOUR (4) countermeasures to reduce the impact of future reoccurrence of similar hacking incident in Q3(b). Critique the effectiveness of the suggested countermeasures.
