Identity Management for the Cloud: A Practical Guide

As organisations move applications, data and infrastructure to the cloud, managing who can access what becomes more complex. Staff may work from different locations, use several cloud services and sign in from a range of devices. At the same time, applications and automated services need identities of their own.

Identity management provides the processes and technology needed to create, verify and manage these identities and their access. Done well, it helps protect cloud resources, supports efficient working and gives organisations a clearer view of access across their environment.

What is cloud identity management?

Cloud identity management is the administration of digital identities and permissions used to access cloud-based systems. It can include user accounts, authentication, single sign-on (SSO), access policies, privileged accounts and machine identities such as application service accounts.

Identity management is closely related to identity and access management (IAM). IAM covers the broader set of policies and tools used to establish identities, authenticate users and decide what they are permitted to do. In a cloud environment, these controls may be spread across a cloud provider, business applications and an organisation’s own directory services.

Why it matters

Cloud services make it easier to provide access quickly, but they can also make access harder to track. Accounts may be created in different systems, permissions can accumulate over time, and former employees or suppliers may retain access if offboarding is incomplete.

Weak identity controls can increase the risk of account compromise, data exposure and disruption. Strong controls help an organisation:

• Confirm that users are who they claim to be.
• Limit access to the systems and information each identity needs.
• Remove or change access promptly when roles or circumstances change.
• Monitor sign-ins and permission changes for suspicious activity.
• Demonstrate how access is managed during audits and compliance reviews.

Core principles for cloud identity management

Use a central identity source where practical

A central identity provider can help organisations manage authentication and access policies consistently across multiple cloud services. It can also make it easier to disable an account or change a user’s access in one place. Integration should be planned carefully: cloud services, legacy systems and third-party applications may not all support the same features.

Enable single sign-on

SSO allows users to sign in once through an identity provider and access approved applications without managing a separate password for each service. This can improve the user experience and make it easier to apply consistent security controls. SSO should be paired with strong authentication and well-protected administrator accounts; by itself, it does not prevent account compromise.

Require multi-factor authentication

Multi-factor authentication (MFA) asks users to prove their identity using more than one factor, such as a password and an authenticator app or security key. It can reduce the risk of stolen passwords being used to access an account. Prioritise MFA for administrators, remote access and accounts that can reach sensitive data. Where available, consider phishing-resistant methods such as passkeys or security keys.

Apply least privilege

Give each user, application and service only the permissions needed to perform its tasks. Avoid broad, permanent permissions when narrower or time-limited access will do. Review roles regularly, especially in cloud platforms where a single permission may expose sensitive data or allow major configuration changes.

Manage the identity lifecycle

Access should follow a person’s relationship with the organisation. When someone joins, they should receive the access required for their role. When they change roles, their permissions should be reviewed. When they leave, accounts, sessions, tokens and other credentials should be revoked promptly.

Automating these steps through joiner, mover and leaver processes can reduce delays and human error. The process should cover employees, contractors, suppliers and other third parties, not just permanent staff.

Don’t overlook non-human identities

Applications, scripts, virtual machines and automation tools often use identities to communicate with other systems. These non-human identities can have significant access, yet they may be less visible than employee accounts.

Maintain an inventory of service accounts, API keys, certificates and other credentials. Assign an owner and a clear purpose to each one, restrict its permissions, and set a process for rotation and revocation. Avoid embedding long-lived secrets in code or configuration files. Where possible, use managed identities or short-lived credentials supplied by the cloud platform.

Use context and monitor access

Authentication decisions can take account of more than a password. Depending on the organisation’s needs and technology, policies may consider factors such as the device, location, sign-in risk or sensitivity of the application. This supports a zero-trust approach: access is evaluated rather than assumed simply because a user is inside a network.

Logging and monitoring are also essential. Record sign-ins, failed authentication attempts, privilege changes and unusual activity. Alerts should be prioritised so that security teams can investigate meaningful risks without being overwhelmed by noise. Logs are most useful when they are retained securely and reviewed as part of a defined incident-response process.

Common challenges

• Too many separate accounts: Different cloud services may create disconnected identity stores, making oversight difficult.
• Excessive permissions: Access granted for a short-term task can remain in place long after it is needed.
• Unmanaged credentials: Old keys, tokens and service accounts can remain active without a clear owner.
• Inconsistent policies: Different teams may configure authentication and access controls in different ways.
• Incomplete offboarding: Removing an employee from one system does not necessarily revoke access to every connected service.

Addressing these challenges starts with visibility. Identify the cloud services in use, map how identities are created and authenticated, and establish who is responsible for each type of access.

A practical starting plan

1. Build an identity inventory. List users, administrators, third parties, applications and service accounts, along with the systems they can access.
2. Protect high-risk accounts first. Require strong MFA, reduce standing privileges and review recovery methods for administrator accounts.
3. Standardise access rules. Define role-based access where appropriate and document how exceptions are approved.
4. Automate lifecycle processes. Connect identity changes to HR and supplier processes where possible, and test that access is removed correctly.
5. Review permissions regularly. Ask managers and system owners to confirm that access remains necessary, paying particular attention to privileged access.
6. Monitor and improve. Use audit logs and incident findings to identify gaps, refine policies and test recovery procedures.

Governance, privacy and compliance

Cloud identity controls should form part of an organisation’s wider security and data-protection arrangements. In the UK, organisations handling personal data should consider their obligations under the UK GDPR and Data Protection Act 2018, including the need for appropriate security measures. The controls required will depend on the organisation, the data involved and the services being used.

Keep policies and evidence proportionate and current. Document who approves access, how privileged permissions are controlled, how long records are retained and how access reviews are completed. Cloud providers may offer security features, but the organisation remains responsible for configuring them appropriately and understanding the division of responsibilities.

Conclusion

Effective identity management is a foundation of cloud security. Centralised authentication, MFA, least-privilege access, reliable lifecycle processes and careful management of service identities can reduce avoidable risk while making access easier to administer.

There is no single configuration that suits every organisation. The best approach begins with a clear picture of identities and permissions, then improves controls according to the sensitivity of the systems and data involved. Regular reviews help ensure that access remains appropriate as people, applications and cloud environments change.

 

Cloud Identity and Access Management: Six Frequently Asked Questions

1. What is identity management in cloud computing?
2. What is authentication management in cloud computing?
3. What are the 5 pillars of IAM?
4. What is IAM practices in the cloud?
5. Is CyberArk Pam or IAM?
6. What is cloud-based identity?

What is identity management in cloud computing?

Identity management in cloud computing is the process of creating, verifying and managing the identities that access cloud services, applications and data. It includes authenticating users, assigning appropriate permissions, and updating or removing access when roles change or accounts are no longer needed. Strong cloud identity management helps ensure that people and services can access only the resources they need, while supporting security, monitoring and compliance.

What is authentication management in cloud computing?

Authentication management in cloud computing is the process of verifying the identity of users, devices and applications before they access cloud services. It includes setting up and managing sign-in methods, such as passwords, single sign-on and multi-factor authentication, as well as applying policies that determine when additional verification is required. Effective authentication management helps prevent unauthorised access while giving legitimate users secure, straightforward access to the resources they need.

What are the 5 pillars of IAM?

The five pillars of Identity and Access Management (IAM) are commonly described as identity governance and administration, access management, privileged access management, identity security and directory services. Together, they cover the full identity lifecycle: creating and managing user accounts and permissions, verifying users at sign-in, protecting powerful administrator accounts, detecting and responding to identity-related risks, and providing a reliable directory of users, devices and services. The exact terminology can vary between organisations and frameworks, but the central aim is to ensure that the right identities have the right access to the right resources at the right time.

What is IAM practices in the cloud?

Cloud IAM practices are the policies and processes used to manage digital identities and control access to cloud services. They typically include verifying users with multi-factor authentication, applying least-privilege permissions, using single sign-on where appropriate, reviewing access regularly, and promptly updating or removing access when roles change or people leave. Good IAM practices also cover non-human identities, such as applications and service accounts, and include monitoring sign-ins and permission changes to help detect suspicious activity.

Is CyberArk Pam or IAM?

CyberArk is best known for Privileged Access Management (PAM), which controls and monitors access to powerful accounts, such as administrator and service accounts. PAM is a specialised part of the broader Identity and Access Management (IAM) field. CyberArk also offers identity security capabilities beyond traditional PAM, so it may be described as an IAM or identity security provider, but its core specialism is PAM.

What is cloud-based identity?

Cloud-based identity is the digital identity used to access online services, applications and resources hosted in the cloud. It may represent a person, such as an employee or customer, or a non-human account, such as an application or service. Cloud identity systems manage how these identities are verified and what they are allowed to access, often using features such as single sign-on, multi-factor authentication and access policies.
