With the advent of technology and the need for mobility, many different organizations come up with different solutions that people can use for their daily tasks. One such service is the cloud service that provides a versatile solution that everyone can use to complete their jobs efficiently and also have the choice to do those tasks from anywhere they are.

We discuss what a cloud is in this blog and what are the implications of it being insecure? We will discuss the protection of the cloud infrastructure and not what is going on inside the cloud infrastructure. For example, this blog will talk about the security of the physical cloud servers and not the virtual operating system running on the cloud server inside a virtual machine.

A cloud is a collection of several computers that are connected together and kept in huge warehouses around the world. A particular cloud infrastructure could either be present in a single building, or it could be spread across multiple buildings that could be located in different geographic areas. Cloud computing is a process used to enhance the performance of a specific task.

Multiple resources that make up the cloud infrastructure share the computing needs. Just as one performs a function on one computer, the person can perform the same task using a cloud service, the difference being that the task can be completed quickly by using the cloud service. A cloud service also provides flexibility in performing the task from anywhere in the world and using any device on which the cloud service can be accessed.

Clouds can be either private clouds that are present on the premises of an organization, public clouds that are present on the premises of a cloud provider and are offered to customers or hybrid clouds that are a mixture of private and public clouds.

There are multiple types of cloud deployment models. Some examples include Infrastructure – as – a – Service (IaaS), Software – as – a – Service (SaaS), and Platform – as – a – Service (PaaS).

Cloud is a boon for people who have to travel and work from different places. Using the cloud, however, involves certain risks. Even clouds are not completely secure. A lot of cyber attacks are possible that can affect the confidentiality, integrity, and availability of cloud resources. In such attacks, an attacker gains access to the network of cloud providers and manages to destroy the virtual servers present on cloud servers.

This would also cause the destruction of all the customer data of cloud providers that were present on those virtual servers. So, while the cloud provider was the main victim of the attacker, the attack would also make customers of cloud providers as victims. This type of attack could cost the cloud provider a lot of money as their own systems would be destroyed, and customers whose data would be affected would also want reimbursement for the loss of their personal data and the losses they had to face as a result of the security incident.

There were 681 million attacks that affected cloud customers in 2018. The attacks mainly took advantage of the software vulnerabilities in the cloud infrastructure, brute-force attacks, and stolen credentials. It was reported that exploit kits were being rented for cloud-focused attacks. Some security incidents could also occur due to an insider if the insider makes a mistake and configures the servers incorrectly, causing the backups to be erased.

 Therefore, the security of the cloud is highly essential as it holds the data of hundreds of thousands of users and massive losses could occur if a cloud infrastructure is breached.
