anonymous proxy is a type of proxy that hides the user’s IP address and other identifying information from the web servers they access. An anonymous proxy acts as an intermediary between the user and the internet, and it modifies the HTTP headers to prevent the web servers from tracking the user’s location, browser, or device. An anonymous proxy can help the user bypass geo-restrictions, censorship, and online surveillance. However, an anonymous proxy does not encrypt the user’s traffic, and it may still leak some information to the proxy provider or other third parties. An anonymous proxy is the type of proxy employed by Mary in the above scenario, as she used a proxy tool that makes her online activity untraceable.References:

A gateway is a component of IoT architecture that collects data from IoT devices and performs data pre-processing. A gateway acts as a bridge between the IoT devices and the cloud platform, and it can filter, aggregate, compress, encrypt, or transform the data before sending it to the cloud for storage and analysis. A gateway can also perform edge computing, which means processing the data locally and providing real-time feedback or actions. A gateway can support various communication protocols, such as WiFi, Bluetooth, Zigbee, or cellular, and it can enhance the security and reliability of the IoT system.A gateway is the component that matches the description given in the question123

The type of attack initiated by Jacob in the above scenario is a cross-container attack. A cross-container attack is a type of attack that targets container technology and exploits the shared resources and network connections between containers. A cross-container attack can compromise the security and availability of multiple containers and the underlying host by performing actions such as stealing data, executing commands, consuming resources, or spreading malware. A cross-container attack can be launched by an external attacker who gains access to a container through a network vulnerability, or by a malicious insider who runs a rogue container on the same host or cluster.A cross-container attack can be prevented or mitigated by implementing security best practices for container technology, such as isolating containers, limiting privileges, enforcing policies, scanning images, and monitoring network traffic123.References:

The loT communication model that serves as an analyzer for a company to track monthly or yearly energy consumption is the device-to-cloud model. The device-to-cloud model is a loT communication model where the loT devices, such as smart meters, sensors, or thermostats, send data directly to the cloud platform, such as AWS, Azure, or Google Cloud, over the internet. The cloud platform then processes, analyzes, and stores the data, and provides feedback, control, or visualization to the users or applications. The device-to-cloud model enables the company to monitor and optimize the energy consumption of the loT devices in real time, and to leverage the cloud services, such as machine learning, big data analytics, or artificial intelligence, to perform advanced energy management and demand response.The device-to-cloud model also reduces the complexity and cost of the loT infrastructure, as it does not require intermediate gateways or servers to connect the loT devices to the cloud123.References:

The cloud layer of IoT architecture is the layer that hosts the servers that accept, store, and process the sensor data received from IoT gateways. The cloud layer also creates dashboards for monitoring, analyzing, and implementing proactive decisions to tackle the issue. The cloud layer provides scalability, reliability, and security for the IoT system.The cloud layer can use various cloud computing models, such as public, private, hybrid, or community clouds12.References:Network Defense Essentials - EC-Council Learning,IoT Architecture: The 4 Layers of an IoT System
