Cloud service is becoming more significant and used. Users don’t have to fear whether their data is physically secured or will get lost. But the question is how secured is the cloud storage? Nowadays, when physical storage and cloud storage have become more common. The loss of backup devices and theft is not really an issue. Data can also be stored on devices as most smartphone devices come with encrypted data storage options. The cloud storage was not only created to solve a human problem but to reduce the tolerance of failure.
Storing your data on the cloud secures your data from compromise, as the cloud storage promises to produce your information when it is needed. The cloud storage has a virtualized infrastructure and runs mainly on software. Servers and services can grow, shrink, appear, transform, and disappear to accommodate the services provided. The servers and services are not fixed but transformed to provide transparency.
About Cloud Services
Research has shown that organizations using several forms of cloud providers are more exposed to risk than those with fewer cloud providers. As it seems, there are still more things to be done to improve the cloud architecture and manage its complexity. In determining the optimal cloud defense strategy, it is important to note that storing user information and securing is essential.
The cloud system uses three cloud service models to store information. These service models are IaaS (Infrastructure-as-a-service), SaaS (Software-as-a-service), and Paas (Platform-as-a-service). It also uses four deployment models namely community, private, hybrid, and public.
Software-as-a-service
The software-as-a-service model is an application service. Examples include Dropbox, Office 365, Adobe Creative Cloud, and more. In this model, users will be responsible for data and logins. This model is vulnerable to threats like credential stuffing, phishing, and credential theft. Controlling these thefts is worth doing and ways to control these solutions include multi-factor authentication, data-at-rest encryption, and application configuration.
Platform-as-a-Service
The second model which is the Platform-as-a-Service helps to build applications into before they are sent to the cloud. In the Platform-as-a-service model, the provider manages the platform infrastructure and lets users build and run the applications. Examples of Platform-as-a-Service include Azure SQL Database, AWS S3 buckets, Heroku, and OpenShift. In this application, there is a need to secure user data against web application attacks. This model exposes Service interfaces and APIs if they’re not secured. Platform-as-a-service can be conveniently operated using Web App Firewalls, User/Role Rights management processes, Web App Security, Web App Security, secure API gateways, Bot scrapers, and all referenced SaaS controls.
Infrastructure-as-a-Service
The other model i.e., Infrastructure-as-a-service is a unique cloud service. It creates virtual machines, other computing infrastructure, and networks. In Infrastructure-as-a-service the deliverer manages and controls the infrastructure of the operating system. It also allows the user to build and run everything from machine to network. Examples of infrastructure-as-a-service include Rackspace, AWS EC2, Microsoft Azure, and Linode. It gives the user the responsibility for servers, operating, networking, as well as everything in the PaaS and SaaS models. In this scenario, the threats affecting SaaS and PaaS models are unique and easy to control.
