Virtual infrastructure services (like virtual machines, virtual storage, and virtual networks) require security solutions specifically designed for a cloud environment. Detail: Use Azure Security Center. If your VM runs critical applications that need to have high availability, we strongly recommend that you use multiple VMs. Best practice: To make sure the encryption secrets don’t cross regional boundaries, Azure Disk Encryption needs the key vault and the VMs to be located in the same region. Or, you can use Azure Backup to help address your backup requirements. Resource abuse can be a problem when VM processes consume more resources than they should. Azure Monitor features: Organizations that don't monitor VM performance can’t determine whether certain changes in performance patterns are normal or abnormal. Popular infrastructure services include Amazonâs Elastic Compute (EC2), the Google Compute Engine, and Microsoft Azure. Don't rush into an Infrastructure as a Service contract without evaluating regulatory compliance requirements, data protection controls, and contractual obligations. You can also import a KEK from your on-premises hardware security module (HSM) for key management. Security Center stores data in Azure Monitor logs. There are very few limitations on what applications can be run on the infrastructure or what tools can be used to run the applications. Infrastructure-as-a-Service Adoption and Risk Report. Detail: Azure Disk Encryption generates and writes the encryption keys to your key vault. The cloud provider may offer tools for securing their resources, but the IT professional is responsible for correct use of the tools. Be sure that you trust all of your subscription admins and coadmins to log in to any of your machines. Detail: Check for and install all Windows updates as a first step of every deployment. Best practice: Take a snapshot and/or backup before disks are encrypted. When a key encryption key is specified, Azure Disk Encryption uses that key to wrap the encryption secrets before writing to Key Vault. VNSP solutions scan network traffic moving both north-south and east-west between virtual instances within IaaS environments. Storage resources and databases are a frequent target for data exfiltration in many data breaches. This fact is evident in hybrid scenarios where organizations want to slowly migrate workloads to the cloud. This article describes security best practices for VMs and operating systems. Moreover, Gartner projects that by 2025, 80% of enterprises will have shuttered their physical data centers in favor of cloud infrastructure services, compared to just 10% today. Cloud security posture management (CSPM). To do this, IT can use a cloud access security broker (CASB). Virtual network security platforms (VNSP). Patch beyond the operating system. Best practice: Keep your VMs current. Attackers constantly scan public cloud IP ranges for open management ports and attempt “easy” attacks like common passwords and known unpatched vulnerabilities. - SLAs can be written to further tighten controls and determine roles and responsibilities. IaaS customers are responsible for securing their data, user access, applications, operating systems, and virtual network traffic. A CASB may also include workload monitoring and security. An IaaS provider is responsible for implementing secure access controls to the physical facilities, IT systems, and cloud services. IaaS Key Features. This level of scalability isn't possible with on-premises hardware. Microsoft Azure provides confidentiality, integrity, and availability of customer data, while also enabling transparent accountability… Unpatched vulnerabilities on partner applications can also lead to problems that can be avoided if good patch management is in place. A common cause of cloud security incidents is misconfiguration of cloud resources. Top IaaS Security Requirements To Consider. Detail: Define your VM with an Azure Resource Manager template so you can easily redeploy it. Following are best practices for using Azure Disk Encryption: Best practice: Enable encryption on VMs. With IaaS in the public cloud, you control the virtual machines and the services running on the VMs you create, but you do not control the underlying compute, network and storage infrastructure. Over 500 organizations currently use the CAIQ to submit self-assessments on the STAR registry. In most infrastructure as a service (IaaS) scenarios, Azure virtual machines (VMs) are the main workload for organizations that use cloud computing. FedRAMP Tailored Low Security Controls 11/14/2017 FedRAMP Mapping of FedRAMP Tailored LI‐SaaS Baseline to ISO 27001 Security Controls Revision History This document provides a list of all controls that require the Cloud Service Provider, Esri, to provide detailed descriptions of ...

Detail: Use Azure policies to establish conventions for resources in your organization and create customized policies. IaaS & Security. Azure VMs, like all on-premises VMs, are meant to be user managed. Gartner reports that IaaS is the fastest-growing segment of the cloud services market and is forecast to grow 27.6% in 2019 to $39.5 billion. IDC predicts that, in two years, spending on cloud infrastructure services will be 15% higher than spending for on-premises IT infrastructure. Many organizations use multi-cloud environments, with IaaS, PaaS, and SaaS services from different vendors. Detail: Manage endpoint protection issues with Security Center. Monitor system activity. Security Center will recommend that you edit these inbound rules to restrict access to source IP addresses that actually need access. We recommend that you evaluate your current software update policies to include VMs located in Azure. Compliance audits. Although images from the Azure Marketplace are updated automatically by default, there can be a lag time (up to a few weeks) after a public release. Encryption is essential to protect the data from theft or unauthorized access. You organize subscriptions into management groups (containers) and apply your governance conditions to those groups. Best practice: Install the latest security updates. We recommend that you use Azure Monitor to gain visibility into your resource’s health. Privileged identity management. Detail: Use Azure RBAC to ensure that only the central networking group has permission to networking resources. See Azure security best practices and patterns for more security best practices to use when you’re designing, deploying, and managing your cloud solutions by using Azure. Poll after poll shows that security remains a major concern for enterprises moving to the cloud. In Security Center, safeguard your VMs by taking advantage of the following capabilities: Security Center can actively monitor for threats, and potential threats are exposed in security alerts. Four important solutions for IaaS security are: cloud access security brokers, cloud workload protection platforms, virtual network security platforms, and cloud security posture management. Azure Disk Encryption uses the industry-standard BitLocker feature of Windows and the DM-Crypt feature of Linux to provide volume encryption for the OS and the data disks. You can obtain the System Security Plan for the CSP you choose, which documents the details of the implementation for each of the shared and inherited controls. Detail: Use a least privilege approach and built-in Azure roles to enable users to access and set up VMs: Your subscription admins and coadmins can change this setting, making them administrators of all the VMs in a subscription. From authentication options to end-point verification, from geographical access control to internal application role-based-access-controls, there’s a plethora of security options that may need to be explored in detail to ensure a practical level of security restrictions are applied. Making sure your security and compliance tools cover these areas is key. Detail: A backup needs to be handled the same way that you handle any other operation. If your organization has many subscriptions, you might need a way to efficiently manage access, policies, and compliance for those subscriptions. Shadow or rogue cloud accounts are most common in software-as-a-service (SaaS) solutions but can also occur in IaaS. Detail: Enable Azure Security Center (Free tier or Standard tier) to identify missing security updates and apply them. Detail: Install a Microsoft partner solution or Microsoft Antimalware, Best practice: Integrate your antimalware solution with Security Center to monitor the status of your protection. 25 Many government and industry regulations require sensitive data to be encrypted at all times, both at rest and in motion. While multi-cloud environments have advantages, they can also become complicated to administer, manage and control. Microsoft Antimalware includes features like real-time protection, scheduled scanning, malware remediation, signature updates, engine updates, samples reporting, and exclusion event collection. Azure Monitor logs provides a query language and analytics engine that gives you insights into the operation of your applications and resources. IaaS: within this model the focus is on managing virtual machines. Examples of common errors include: Shadow services. If your Azure VMs host applications or services that need to be accessible to the internet, be vigilant about patching. Network Security In Public or Hybrid Cloud models, data will travel across the Internet and cloud services clients will connect to cloud services over the Internet. For Azure IaaS components this means the security controls within the VM operating system, network and Azure environment, but not backend components, such as the Azure management plane. An IT department may also want to encrypt data in transit. There is often a shared security responsibility between the user and the cloud provider. the security of that resource is your responsibility. Best practice: Identify and remediate exposed VMs that allow access from “any” source IP address. Based off of the security controls in the CCM, the questions can be used to document which security controls exist in a provider’s IaaS, PaaS, and SaaS offerings. Organizations that don't enforce strong security for their VMs remain unaware of potential attempts by unauthorized users to circumvent security controls. The minimum security standards found here apply to IaaS managed services — virtual servers that are designed to be ephemeral — and containerized solutions. What to do. 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. While the customer is in control of the apps, data, middleware, and the OS platform, security threats can still be sourced from the host or other virtual machines (VMs). Moderate Risk. . When you use Azure AD authentication for Linux VMs, you centrally control and enforce policies that allow or deny access to the VMs. They may integrate with firewalls and cloud platform APIs, as well as monitor IaaS for misconfigurations and unprotected data in cloud storage. Because a client is not in full control of the server environment, it may be … Azure doesn't push Windows updates to them. After a backup is made, you can use the Set-AzVMDiskEncryptionExtension cmdlet to encrypt managed disks by specifying the -skipVmBackup parameter. Production workloads moved to Azure should integrate with existing backup solutions when possible. Azure Disk Encryption helps you encrypt your Windows and Linux IaaS virtual machine disks. Access management; 2. Best practice: Rapidly apply security updates to VMs. Traditional enterprise security solutions aren't built for cloud services, which are outside the organization's firewall. Ongoing monitoring for access, security and availability. An IaaS provider is responsible for the entire infrastructure, but users have total control over it. Improperly configured inbound or outbound ports, Multi-factor authentication not activated. One reason IaaS usage is increasing is the low upfront cost. Best practice: Control VM access. As an example: 5.5% of Amazon Web Services (AWS) S3 buckets in use are misconfigured to be publicly readable, which could result in significant loss of data. Identify and download system security and critical updates that might be missing. In terms of security requirements, IaaS must implement security effectively at the level of the host, virtual machine, compute, memory, network and storage. Apply these policies to resources, such as resource groups. SASE from Masergy: Best-of-breed technologies, broad choices, and security that goes beyond SASE November 16, 2020. User role-based permissions. To secure the data in these services, IT needs to first identify the services and users through an audit. Standards. The solution also ensures that all data on the virtual machine disks are encrypted at rest in Azure Storage. The solution is integrated with Azure Key Vault to help you control and manage the disk-encryption keys and secrets in your key vault subscription. High Risk. IT managers can evaluate IaaS providers based on the following characteristics: According to Gartner, IaaS will be the fastest-growing segment of the public cloud services market, forecasted to grow by 27.6% in 2019 to reach $39.5 billion, up from $31 billion in 2018. As data centers move into the cloud, IT managers need to create IaaS security strategies and implement cloud security technologies to protect their essential infrastructure. For environments that are hosted separately from your production environment, you can use an antimalware extension to help protect your VMs and cloud services. Identity and access management is essentially the responsibility of the cloud consumer in the IaaS model, sinc… Oracle Cloud Infrastructure enables enterprises to maximize the number of mission-critical workloads that they can migrate to the cloud while continuing to maintain their desired security posture and reduce the overhead of building and operating data-center infrastructure. Cloud infrastructure can be expanded on-demand and scaled back again when no longer needed. In such scenarios, follow the general security considerations for IaaS, and apply security best practices to all your VMs. A VM that’s consuming more resources than normal might indicate an attack from an external resource or a compromised process running in the VM. The following resources are available to provide more general information about Azure security and related Microsoft services: Install a Microsoft partner solution or Microsoft Antimalware, Manage endpoint protection issues with Security Center, identify missing security updates and apply them, client certificate-based Azure AD authentication, Azure security best practices and patterns, Microsoft Monitoring Agent (MMA) for Windows or Linux, PowerShell Desired State Configuration (DSC) for Linux, Microsoft Update or Windows Server Update Services (WSUS) for Windows computers. Detail: Use the Update Management solution in Azure Automation to manage operating system updates for your Windows and Linux computers that are deployed in Azure, in on-premises environments, or in other cloud providers. Care must be taken both during initial service selection (making sure it has security controls that can help you assess your security posture) and that sufficient information is available to re-assess security over time. It’s imperative to monitor VM access not only reactively while an issue is occurring, but also proactively against baseline performance as measured during normal operation. Detail: Some of the first workloads that customers move to Azure are labs and external-facing systems. It’s important to note that we’re talking about day-to-day responsibilities here. They may use their own encryption keys or IaaS-provider encryption. Organizations that control VM access and setup improve their overall VM security. 3. When JIT is enabled, Security Center locks down inbound traffic to your Azure VMs by creating a network security group rule. For better availability, use an availability set or availability zones. This is true of systems that are part of your production environment extending to the cloud. Users should be given only the access necessary to perform their work. Data is also collected from Azure Monitor, management solutions, and agents installed on virtual machines in the cloud or on-premises. Iaas, PaaS or SaaS? Backups provide a recovery option if an unexpected failure happens during encryption. Create an Azure AD application for this purpose. This results in an average of 2,269 misconfiguration incidents per month. Responsibility for the aforementioned cloud models is roughly divided between users and providers. This blueprint will comprehensively evaluate your hosted cloud risk profile to determine what unique security controls your organization requires to secure its cloud environment. Keep software up-to-date. Best practice: Restrict management ports (RDP, SSH). You can take each type of service (IaaS, PaaS, SaaS) and apply reasonable security controls in order to fulfill your day-to-day responsibilities. This makes IaaS appealing to organizations of all sizes. The first step in protecting your VMs is to ensure that only... Use multiple VMs for better availability. Detail: Create and use a key vault that is in the same region as the VM to be encrypted. The types of controls that should be considered to protect organizational workloads within IaaS deployments include next-generation firewalls (NGFW), micro-segmentation, server anti-malware, log management/security information event management (SIEM), and security orchestration. Test and dev systems must follow backup strategies that provide restore capabilities that are similar to what users have grown accustomed to, based on their experience with on-premises environments. Best practice: Periodically redeploy your VMs to force a fresh version of the OS. Best practice: Secure privileged access. IaaS is also more scalable and flexible than hardware. Looking at cloud security in this manner brings clarity. Establish who should access which system components, and how often, and monitor those component… IaaS: within this model the focus is on managing virtual machines. For both scenarios, you should consider the following security issues: This segmentation is addressed from a compliance perspective by Microsoft obtaining the The first step in protecting your VMs is to ensure that only authorized users can set up new VMs and access VMs. Despite all that concern, companies appear to be increasingly adopting … Organizations increasingly use cloud-based infrastructure services to augment on-premises or private cloud environments, or to create entirely cloud-based IT environments. User privileges should be reviewed periodically to determine relevance to current work requirements. Computers that are managed by Update Management use the following configurations to perform assessment and update deployments: If you use Windows Update, leave the automatic Windows Update setting enabled.
