SSID cloaking is a security measure that involves hiding the Service Set Identifier (SSID) of a wireless network from being broadcasted openly. This prevents the SSID from appearing in the list of available networks on devices within range, reducing the likelihood of unauthorized access attempts. While it does not provide complete security on its own, it is considered a layer of defense that can deter casual attempts to connect to a network. It is important to note that SSID cloaking should be used in conjunction with other security measures, such as strong encryption and authentication protocols, to effectively secure a wireless network.

References: The best practices for wireless network security include using strong passwords, enabling encryption, and employing security measures like SSID cloaking to minimize the visibility of the network to unauthorized users12. These practices are aligned with the objectives and guidelines provided by the EC-Council’s Certified Network Defender (CND) program.

 In the context of cloud security, the responsibility is shared between the cloud provider and the cloud consumer. This is known as the shared responsibility model. The cloud provider is responsible for securing the infrastructure that runs all of the services offered in the cloud. On the other hand, the cloud consumer is responsible for managing the security of their data, applications, and operating systems that they run on the cloud infrastructure. The specific responsibilities can vary depending on the service model being used (IaaS, PaaS, SaaS), but the underlying principle is that both parties have a role to play in ensuring the security of cloud services.

References: The concept of shared responsibility in cloud security is widely acknowledged and documented by various cloud service providers and security organizations, including Microsoft Azure1 and the Center for Internet Security (CIS)2. These sources provide detailed explanations of the shared responsibility model and outline the security tasks handled by the cloud provider and those that fall under the cloud consumer’s purview.

 The type of UPS that is used to supply power above 10kVA and provides an ideal electric output presentation, while its constant wear on the power components reduces dependability, is the Double conversion on-line UPS. This UPS system works by converting the incoming AC power to DC to charge the batteries and then converting it back toAC for the connected equipment. This double conversion process provides a very clean and stable power supply, which is ideal for sensitive electronic equipment. However, because the power components are constantly in use, they tend to wear out more quickly, which can reduce the overall dependability of the system12.

References: The information provided is consistent with industry standards for UPS systems and their applications, particularly for power requirements above 10kVA. The double conversion on-line UPS is recognized for its ability to deliver high-quality power output, which is essential for critical systems and applications12.

Virtual machines (VMs) operate based on hardware-level virtualization, which means they emulate entire hardware systems, including CPUs, memory, and network interfaces, allowing multiple operating systems to run on a single physical machine. Each VM includes a full copy of an operating system, the application, necessary binaries, and libraries - taking up tens of GBs. VMs are completely isolated from the host OS, which is why they do not share the host OS. This is in contrast to containers, which share the host system’s kernel and are more lightweight as they do not require a full OS within each container.

References: The Certified Network Defender (CND) course by EC-Council covers various aspects of network security, including enterprise virtual network security, which encompasses the use of VMs and their characteristics12.
