What's cyber security?

Computer security, cybersecurity or information technology security (IT security) is the security of computer systems in the theft of or damage to their own hardware, applications, or digital information, in addition to in the disruption or misdirection of their solutions they supply. The area is becoming more important because of greater reliance on computer technologies, the web and wireless system standards like Bluetooth and Wi-Fi, and as a result of development of "smart" devices, such as televisions, smartphones, and the numerous devices which constitute the"Internet of things". Due to its complexity, both regarding science and politics, cybersecurity can also be one of the significant challenges in the modern world.

What's cyber security?

Organizations face many threats to their data systems and information. Knowing all of the fundamental elements to cyber safety is the first step to fulfilling these threats.

Types of cyber security.

The reach of cyber protection is broad. The core regions are explained below, and some other fantastic cyber security plan must take all of them into consideration.

Critical infrastructure includes the cyber-physical systems which society is based on, for example, electricity grid, water purification, traffic lighting and hospitals. Plugging a power plant to the world wide web, as an instance, makes it vulnerable to cyber attacks. The solution for associations accountable for critical infrastructure would be to carry out due diligence to safeguard recognize the vulnerabilities and protect from them. Everyone else must evaluate the way an attack on critical infrastructure that they rely on could impact them and develop a contingency plan.

Network security guards against malicious intrusion in addition to malicious insiders. Ensuring network security frequently requires trade-offs. By way of instance, access controls like additional logins may be required, but slow down productivity. Tools used to track network safety create a great deal of information -- so much that legitimate alarms are often overlooked. To help better handle network security monitoring, safety teams are using machine learning how to flag abnormal traffic and alert to risks in real time.

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing. Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

IoT describes a huge array of crucial and non-critical cyber physiological systems, such as appliances, sensors, printers and safety cameras. IoT devices often ship in an insecure condition and give little to no security, posing risks to not just their customers, but also to other people online, since these devices frequently find themselves part of a botnet. This presents special security challenges for the home users and society.

What Is Azure?

Microsoft Azure is a public cloud computing platform offering several solutions, including Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). With these solutions, Azure can be used for storage, analytics, network, and virtual computing services. Azure can either supplement or replace your on-premises servers.

What Is Azure Virtualization?

Virtualization creates a virtual or simulated computing environment as an alternative to a physical environment. Virtualization can be used to create versions of operating systems, hardware, storage devices, and more. These virtual components allow organizations to partition a single physical server or computer into multiple virtual machines. Each of these virtual machines can then interact independently and run different applications or operating systems, all while sharing the resources of a single host machine.

By creating the opportunity for multiple resources to be accessed from a single server or computer, virtualization improves workloads and scalability. The benefits of virtualization include the need for less maintenance, fewer infrastructure costs, less energy consumption, and fewer servers.

Virtualization falls into four main categories – desktop virtualization, network virtualization, software virtualization, and storage virtualization. Each serves a different purpose.

  • Desktop virtualization allows for one centralized server to deliver and manage multiple individualized desktops
  • Network virtualization splits network bandwidth into independent channels which are then assigned to specific devices or servers
  • Software virtualization separates applications from the hardware and operating system
  • Storage virtualization combines multiple network storage resources into one storage device, which numerous users can access

What Is Azure Nested Virtualization?

With Azure nested virtualization, you’re effectively nesting a hypervisor within a hypervisor. The hypervisor running the main virtual machine is considered to be a level 0, otherwise known as an L0 hypervisor. The initial hypervisor running inside the virtual machine is a level 1 or L1 hypervisor. Any further nested virtualization would result in a level 2 (L2), then a level 3 (L3), and so on.

Because of the differences between Hyper-V virtual machines and Azure virtual machines, you’re unable to simply replicate a Hyper-V virtual machine to Azure and then run the Azure virtual machine as a replica. Azure nested virtualization is the solution to this problem. With the Azure nested virtualization capability, you can run a virtual machine inside a virtual machine. This means a Windows Server virtual machine, for example, can be deployed in Azure and can run nested virtual machines of the Hyper-V format. This environment allows you to replicate local Hyper-V virtual machines to Azure.

Nested virtualization can also be used for testing and development purposes. It can assist with virtualization training, providing guest virtualization to end users, and deployment testing of virtual clouds. Generally speaking, Azure nested virtualization is suited to instances where running multiple hypervisors on the same host server might be beneficial.

Azure Virtualization Technology

Azure virtual machines are one of several types of scalable, on-demand computing resources offered by Azure. As this guide has already touched on, virtual machines give you greater control over your computing environment. With Azure virtual machines, you have more virtualization flexibility without the need to purchase and maintain the physical hardware running it. However, you’ll still need to maintain the virtual machine by performing certain tasks, including patching, configuring, and installing software.

Azure virtual machines can be used in the following ways:

  • Development and testing: Azure virtual machines provide a quick and easy way of creating a computer with the specific configurations required for coding and testing an application.
  • Applications in the cloud: It sometimes makes economic sense to run a virtual machine in Azure because application demand can fluctuate. With Azure, you can pay for extra virtual machines when you need them and deactivate them when you don’t.
  • Extended data center: Virtual machines in an Azure virtual network can be easily connected to your organization’s network.

The number of virtual machines used by your application can be scaled up to suit your changing requirements, when necessary.

When you create a virtual machine, there are several design considerations to take into account. These are as follows:

  • The names of your application resources
  • The size of the virtual machine
  • The location of stored resources
  • The maximum number of virtual machines that can be created
  • The configuration of the virtual machine after it starts
  • The operating system the virtual machine runs
  • The related resources required by the virtual machine

Installing Hyper-V in Azure Nested Virtualization

To successfully provision a nested virtual machine inside Microsoft Azure, follow these steps:

  1. Create an Azure virtual machine capable of nesting (i.e., a Windows Server 2016 or Windows 10 Anniversary edition virtual machine)
  2. Connect to the Azure virtual machine
  3. Install the Hyper-V feature inside the virtual machine
  4. Create a NAT’ed vSwitch to facilitate outside connectivity
  5. Create a guest virtual machine
  6. Configure an IP address on the nested guest virtual machine
  7. Test connectivity

Make sure you carefully consider the size of the virtual machine to be created in Azure. Ensure the virtual machine chosen is big enough to run nested virtual machines. Usually, you’ll need a multiple vCPU configuration with a substantial amount of memory to do this.

Azure Nested Virtualization Use Cases

There are several potential use cases for running Azure nested virtualization on top of Hyper-V. Development and testing is a prominent example already mentioned briefly in this guide. The nested environment can easily be delegated to developers to facilitate the testing of multiple virtual machine environments. Running Hyper-V in Azure means developers are able to provision their own virtual machines within the nested environment.

Another viable use case for Azure nested virtualizations is the ability to test multi-server configurations without the need for provisioning the servers as either actual physical servers or individual virtual machines. With nested virtualization, running entire Windows Failover Server cluster environments within an individual Hyper-V virtual machine is possible. This can be provisioned in Microsoft Azure.

Nested virtualization also provides the opportunity for real production in the form of containers. With Windows Server containers, the containers share the kernel of the host operating system. For extra security, Hyper-V containers allow for the isolation of containers to the kernel of the parent operating system. This is a provisioned virtual machine within which the containers run, and is located on the Hyper-V host. Azure supports Hyper-V containers for production use.
