Increasingly, CASBs are adding CSPM functionality. IaaS & Security. By using resource groups, you can deploy, monitor, and roll up billing costs for your resources. In hybrid and multi-cloud environments, data moves between on-premises and cloud-based resources, and between different cloud applications. Many organizations use multi-cloud environments, with IaaS, PaaS, and SaaS services from different vendors. You can take each type of service (IaaS, PaaS, SaaS) and apply reasonable security controls in order to fulfill your day-to-day responsibilities. 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. IaaS providers are responsible for the controls that protect their underlying servers and data. Standards. Security Center will recommend that you edit these inbound rules to restrict access to source IP addresses that actually need access. This segmentation is addressed from a compliance perspective by Microsoft obtaining the We recommend that you consolidate VMs with the same lifecycle into the same resource group. Organizations increasingly use cloud-based infrastructure services to augment on-premises or private cloud environments, or to create entirely cloud-based IT environments. To comply with industry regulations, companies must prove that they are diligent and using correct security controls to help ensure the security of their workloads located in the cloud. Storage resources and databases are a frequent target for data exfiltration in many data breaches. Best practice: Ensure at deployment that images you built include the most recent round of Windows updates. This results in an average of 2,269 misconfiguration incidents per month. 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. 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. All subscriptions within a management group automatically inherit the conditions applied to the group. CASBs provide visibility and control over cloud resources, including user activity monitoring, IaaS monitoring, cloud malware detection, data loss prevention, and encryption. If your organization has many subscriptions, you might need a way to efficiently manage access, policies, and compliance for those subscriptions. Detail: Just-in-time (JIT) VM access can be used to lock down inbound traffic to your Azure VMs, reducing exposure to attacks while providing easy access to connect to VMs when needed. Security Center stores data in Azure Monitor logs. 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. 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. If a hardware or Azure software failure occurs, only a subset of your VMs are affected, and your overall application continues to be available to your customers. In addition, attackers who successfully infiltrate an organization's infrastructure services can then leverage those accounts to gain access to other parts of the enterprise architecture. 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. Detail: Enable Azure Security Center (Free tier or Standard tier) to identify missing security updates and apply them. Using AWS, you will gain the control and confidence you need to securely run your business with the most flexible and secure cloud computing environment available today. This measure is especially important to apply when you deploy images that come from either you or your own library. IaaS is also more scalable and flexible than hardware. Best practice: Take a snapshot and/or backup before disks are encrypted. Detail: Use Azure Security Center. Cyberthreats are evolving. Top IaaS Security Requirements To Consider. 25 When employees need to provision an application or resource, they may use a cloud provider without informing their IT department. Detail: Use Azure RBAC to ensure that only the central networking group has permission to networking resources. 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. They may use their own encryption keys or IaaS-provider encryption. IaaS, or Infrastructure-as-a-Service, is the traditional cloud model provided by, e.g., Amazon AWS.Essentially, the cloud service provider offers virtual machines, containers, and/or serverless computing services. Poll after poll shows that security remains a major concern for enterprises moving to the cloud. CASBs provide auditing and monitoring of security settings and configurations, file access permissions, and compromised accounts. IaaS VMs start under customer-controlled keys and policies, and you can audit their usage in your key vault. Using a template gives you a patched and secure VM when you need it. You need to manage your VM updates. This blueprint will comprehensively evaluate your hosted cloud risk profile to determine what unique security controls your organization requires to secure its cloud environment. Best practice: Identify and remediate exposed VMs that allow access from “any” source IP address. Attackers constantly scan public cloud IP ranges for open management ports and attempt “easy” attacks like common passwords and known unpatched vulnerabilities. Unpatched vulnerabilities on partner applications can also lead to problems that can be avoided if good patch management is in place. For authentication purposes, you can use either client secret-based authentication or client certificate-based Azure AD authentication. Identity management; and 3. Managing encryption keys in your key vault requires Azure AD authentication. SASE from Masergy: Best-of-breed technologies, broad choices, and security that goes beyond SASE November 16, 2020. Production workloads moved to Azure should integrate with existing backup solutions when possible. After a backup is made, you can use the Set-AzVMDiskEncryptionExtension cmdlet to encrypt managed disks by specifying the -skipVmBackup parameter. Learn more about McAfee cloud security technology. 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. There is often a shared security responsibility between the user and the cloud provider. A CASB may also include workload monitoring and security. Over 500 organizations currently use the CAIQ to submit self-assessments on the STAR registry. What to do. 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. For more information about how to back up and restore encrypted VMs, see the Azure Backup article. There are very few limitations on what applications can be run on the infrastructure or what tools can be used to run the applications. Privileged identity management. It’s important to note that we’re talking about day-to-day responsibilities here. Detail: Define your VM with an Azure Resource Manager template so you can easily redeploy it. However, IaaS can be a target for cyberattacks attempting to hijack IaaS resources to launch denial-of-service attacks, run botnets, or mine cryptocurrencies. -CSPs are largely in control of application security In IaaS, should provide at least a minimum set of security controls In PaaS, should provide sufficiently secure development tools - Customers can control access & authentication into their network. This leaves us with a top reason that API-level connectivity and control for IaaS and PaaS is important: to extend the speed, scale, and consistency benefits of API-based automation to security and compliance. Identity and access management is essentially the responsibility of the cloud consumer in the IaaS model, sinc… VMs that belong to a resource group inherit its policies. User privileges should be reviewed periodically to determine relevance to current work requirements. Best practice: Control VM access. Be sure that you trust all of your subscription admins and coadmins to log in to any of your machines. Because opinions and technologies can change over time, this article will be updated to reflect those changes. According to the McAfee Cloud Adoption and Risk Report, the average organization has at least 14 misconfigured IaaS instances running at any given time.
