Start by knowing which cloud assets and data matter, then secure access, reduce misconfiguration and exposure, monitor activity, and make recovery dependable. These controls reduce risk; none can prevent every incident. Cloud security is also shared: what your organization must configure and protect depends on the cloud service and provider.
1. Map cloud assets, important data, and responsibilities
You cannot protect what you do not know you use. Build an inventory of cloud accounts, services, applications, data stores, integrations, and the teams responsible for them. Identify sensitive or business-critical data and the systems that would disrupt operations if unavailable. Include approved services and cloud resources created outside central IT, where your organization can identify them.
For each service, document who manages each relevant security layer: your organization, the provider, or both. Responsibilities vary between infrastructure, platform, and software services; in SaaS, for example, the provider manages much of the underlying infrastructure, while the customer still has responsibilities such as account access and data handling. CISA’s #StopRansomware Guide puts the point plainly: “Review the shared responsibility model for cloud and ensure you understand what makes up customer responsibility when it comes to asset protection.”
Use the inventory and responsibility map to assign owners, prioritize protections, and identify gaps rather than assuming a provider covers every control.

2. Harden identity and privileged access
Cloud accounts are control points for data, configuration, and infrastructure. Require multifactor authentication (MFA), prioritizing phishing-resistant methods where your identity provider and services support them. Confirm that recovery procedures are secure too; a strong sign-in method is undermined if account recovery is easy to abuse.
Limit permissions to what each person, workload, or administrator needs for its role. Keep privileged accounts restricted, separate administrative work from routine use where practical, and review access when roles change or accounts are no longer needed. CISA’s Cloud Security Technical Reference Architecture recommends phishing-resistant MFA and more granular permissions for privileged accounts.
Zero-trust practices can help teams make access decisions using context rather than assuming that a user or device is trustworthy because it is inside a network. NIST’s SP 1800-35, published in June 2025, describes example zero-trust implementations across on-premises and multiple cloud environments; it is guidance, not a requirement to buy a particular product.

3. Secure configurations and reduce exposure
Use secure configuration baselines that fit each service, then review changes against them. Check the settings your organization controls, such as access policies, network exposure, storage permissions, and service features. Do not assume that a baseline for a virtual machine applies unchanged to a managed platform or SaaS application.
NIST SP 800-210 explains that access-control emphases differ across infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Its cloud access-control guidance is useful for tailoring controls to the service model. Where an organization uses multiple providers, configuration and change processes also need to account for variation between environments. NIST IR 8613 is an initial public draft discussing multi-cloud challenges, including configuration and change management; it should not be treated as final guidance.
Cloud security posture management (CSPM) capabilities can help identify risky configurations, identity issues, and monitoring gaps, but they do not replace ownership and review. CISA describes these capabilities in its Cloud Security Technical Reference Architecture. Set a process for triaging findings, assigning fixes, and checking that changes do not reopen known exposures.

4. Monitor activity and prepare to respond
Enable audit logging for the cloud services and accounts your organization relies on. Prioritize administrative actions, changes to security settings, unusual access patterns, and failed sign-ins. Decide who reviews alerts, how urgent events are escalated, and what actions responders can take to contain a compromised account or exposed resource.
Centralize logs where your team can correlate activity across services, and restrict who can change retention settings or disable logging. NIST SP 800-171 Rev. 3 discusses least privilege and event selection for audit logging—including privileged functions and failed logons—in the specific context of protecting controlled unclassified information in nonfederal systems; it is a useful control reference, not a universal compliance mandate. CISA’s #StopRansomware Guide also recommends enabling logging and alerts for abnormal use.

5. Keep protected backups and test restoration
Keep recovery copies of important data and systems, and make sure attackers who compromise ordinary cloud accounts cannot readily delete or overwrite every copy. CISA recommends backing up often, including offline or cloud-to-cloud backups, and considering delete protection or object lock for cloud storage in its #StopRansomware Guide.
Choose protections that match your recovery needs and the cloud services involved. Separate backup access from everyday administration where possible, protect backup credentials, and define how long copies are retained. Most importantly, test restoration: verify that teams can recover the data and services needed to resume operations, and record any dependencies or delays the exercise reveals.
