The infrastructure is delivered to customers on demand while being fully managed by the service provider. Infrastructure as a Service IaaS is a cloud computing service where enterprises rent or lease servers for compute and storage in the cloud. Users can run any operating system or applications on the rented servers without the maintenance and operating costs of those servers.
Other advantages of Infrastructure as a Service include giving customers access to servers in geographic locations close to their end users. IaaS automatically scales, both up and down, depending on demand and provides guaranteed service-level agreement SLA both in terms of uptime and performance. It eliminates the need to manually provision and manage physical servers in data centers. Infrastructure as a Service IaaS can be more efficient for an enterprise than owning and managing its own infrastructure.

According to the McAfee Cloud Adoption and Risk Report , the average organization has at least 14 misconfigured IaaS instances running at any given time. This results in an average of 2, misconfiguration incidents per month. As an example: 5. The cloud provider may offer tools for securing their resources, but the IT professional is responsible for correct use of the tools.
Examples of common errors include:. Shadow services. Shadow or rogue cloud accounts are most common in software-as-a-service SaaS solutions but can also occur in IaaS. When employees need to provision an application or resource, they may use a cloud provider without informing their IT department. To secure the data in these services, IT needs to first identify the services and users through an audit.
User role-based permissions. It is a best practice to protect access to cloud infrastructure by ensuring that developers and other users have only the permissions they need to do their jobs—and no more. Lock root account credentials that can provide an attacker access to all resources, and deprovision inactive accounts. In this report we uncover the rise of Cloud-Native Breaches, disconnect between security, practitioners and their leadership, and the state of multi-cloud adoption.
Multi-cloud environments are becoming more common but can also cause security challenges. Traditional enterprise security solutions aren't built for cloud services, which are outside the organization's firewall. Virtual infrastructure services like virtual machines, virtual storage, and virtual networks require security solutions specifically designed for a cloud environment.
Four important solutions for IaaS security are: cloud access security brokers, cloud workload protection platforms, virtual network security platforms, and cloud security posture management. CASBs provide visibility and control over cloud resources, including user activity monitoring, IaaS monitoring, cloud malware detection, data loss prevention, and encryption.
They may integrate with firewalls and cloud platform APIs, as well as monitor IaaS for misconfigurations and unprotected data in cloud storage. The model also protects against single points of failure. For example, a physical server could be located across different data centers or even countries , so if an extreme failure forced a data center offline, there would be no disruption.
Another example: Pooled server resources allow maintenance, such as patching operating systems. These processes can be carried out on servers and networks without disruption by using the cloud service. Responsive scalability of cloud servers means that services offer significant cost savings for the end user. Customers pay only for what they use and are not required to pay up front for capacity they may not need, avoiding the setup costs of bringing individual servers online.
Conversely, any setup costs from bringing cloud servers online are overhead for the cloud provider. Cloud models also allow providers to avoid long-term lock-ins.
Removing that tension pairs customers and providers on the same side of progress. Infrastructure as a service IaaS cloud computing offers customers access to computing resources such aslike servers, storage, and networking. Platform as a service PaaS is a cloud environment in which customers can develop, manage, and deliver applications.
Customers can also use a variety of prebuilt tools to develop, customize, and test applications. Customers do not install applications on any local devices. Instead, the applications live on remote clouds and are network-accessed through the web or API.
From this application, users can store and analyze data, and collaborate on projects collaborate.
