Episode 74: IAM Lifecycle and Governance
Welcome to The Bare Metal Cyber CISSP Prepcast. This series helps you prepare for the ISC squared CISSP exam with focused explanations and practical context.
Today, we turn our attention to a central topic in cybersecurity architecture and compliance—Identity and Access Management, or IAM. Specifically, we’ll explore the IAM lifecycle and the governance structures that surround it. These elements are essential not only for securing organizational access but also for ensuring that access stays appropriate, compliant, and traceable throughout a user’s engagement with the organization.
At its core, IAM lifecycle management is about managing digital identities and their access privileges from start to finish—from the moment someone joins your organization, to when they change roles, and ultimately to when they leave. Effective IAM lifecycle management prevents lingering access permissions, minimizes risk, and ensures that security controls reflect current business realities.
Think of the IAM lifecycle in stages. It begins with provisioning, where a new user is granted an identity and given access to the systems they need. This process should be tied directly to the individual’s role. If they work in finance, they shouldn’t get access to human resources databases or marketing analytics tools unless there’s a clear business need.
After provisioning comes account maintenance. Over time, users take on new projects, change departments, or take on additional responsibilities. This makes ongoing maintenance and access review critical. Organizations must regularly examine who has access to what—and whether those privileges are still appropriate.
Then there’s role management. This is where the organization aligns user permissions with specific job roles. You want to define clear boundaries. An accountant should have access to the general ledger but not the security camera feeds. A marketing coordinator should be able to view customer feedback but not manipulate payroll files. When roles change, access must change accordingly.
And eventually, every user will reach the de-provisioning stage. Whether through retirement, resignation, termination, or job transition, access must be revoked swiftly and completely. Delays or oversights during this stage create real risk. Former employees, contractors, or third-party partners should never retain access after their engagement ends.
Now let’s talk about governance. IAM governance refers to the policies, oversight, and decision-making structures that make the entire IAM lifecycle work effectively and securely. It ensures that identity-related processes are carried out consistently, in alignment with security policies, and in compliance with relevant regulations.
IAM governance provides the framework for who approves access, how changes are tracked, and how violations are detected and responded to. It supports accountability and transparency. Strong governance ensures that when the auditors arrive—or when an incident occurs—you can answer with confidence: who accessed what, when, and why?
IAM governance also includes policy development—such as defining how roles are created, what attributes drive access decisions, and how exceptions are handled. Without governance, IAM quickly becomes fragmented, informal, and vulnerable to error or abuse.

So how do we implement IAM lifecycle and governance effectively?
It starts with clear documentation. Every phase of the identity lifecycle should be governed by written policies—how new users are onboarded, how credentials are issued, how access changes are approved, and how offboarding is handled. These policies should be detailed, enforced, and reviewed regularly.
Next, consider automation. Modern IAM platforms allow organizations to automate provisioning, de-provisioning, access reviews, and even password resets. Automation reduces errors, enforces policy, and speeds up response time—critical benefits in large or fast-moving organizations.
You also need regular audits and assessments. Are user accounts being reviewed quarterly? Are there orphaned accounts sitting idle? Are privileged access permissions being monitored and justified? Regular review helps keep IAM practices sharp, secure, and compliant.
Credential security is another must. Use multi-factor authentication wherever possible. Require strong, complex passwords and rotate them regularly. For sensitive roles or administrative accounts, use privileged access management tools to enforce additional controls and scrutiny.
Let’s shift briefly to the security controls that support effective IAM. First, use centralized IAM platforms that integrate with your directory services, cloud apps, and on-premise systems. This gives you a unified view and control point for managing identity across the environment.
Second, implement privileged access controls. Admins, root users, and system-level accounts should be tightly restricted, closely monitored, and used only when necessary. Implement session recording and keystroke logging for administrative activities to maintain accountability.
Third, enable real-time monitoring of identity-related activity. Set alerts for failed login attempts, new admin account creation, and privilege escalations. Use SIEM systems or identity analytics to detect unusual behaviors and respond quickly.
Fourth, patch your IAM software. Whether it’s a cloud-based IAM platform or an on-premise directory service, it must be kept up-to-date to avoid vulnerabilities that attackers can exploit.
Fifth, ensure comprehensive training. Every person involved in IAM—whether approving access, managing credentials, or enforcing policy—needs to understand the organization’s IAM rules and security expectations.
Continuous improvement is the final piece. IAM isn't static. As your workforce evolves, your applications expand, and your regulatory requirements change, your IAM strategies must adapt. That means updating policies, refining access models, improving detection and response capabilities, and investing in technologies that support those goals.
Governance councils, steering committees, and cross-functional IAM working groups can all contribute to this improvement. Don't silo IAM inside IT. Engage security teams, compliance officers, business units, and human resources to ensure IAM governance reflects both organizational risk and operational need.
As you prepare for the CISSP exam, remember these key ideas: the IAM lifecycle includes provisioning, maintenance, access review, and de-provisioning. Governance defines how those processes are managed. Both must work in tandem to maintain secure access, support accountability, and reduce identity-related risks across your environment.
