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:
