Introduction
Enterprises have matured beyond identity and access management (IAM) at the login screen. Attackers now exploit post-login sessions, abusing legitimate credentials to move laterally, escalate privileges, and persist undetected.
This is where PAM (Privileged Access Management) and IGA (Identity Governance & Administration) step in. While IAM decides who can log in, PAM and IGA govern what happens after login, ensuring least privilege and compliance-grade oversight.
At CyberDudeBivash, we break down PAM vs IGA, their overlaps, and how to build a post-login governance stack for 2025.
Why Post-Login Governance Matters
-
Credential Theft: Most ransomware and APT campaigns begin with valid credentials.
-
Insider Threats: Malicious or negligent insiders abuse excessive access.
-
Compliance Pressure: Regulations (GDPR, SOX, HIPAA) demand audit trails of access usage, not just authentication.
-
Zero Trust Evolution: Beyond login, continuous verification and contextual access are required.
PAM vs IGA — Core Differences
| Feature | PAM (Privileged Access Management) | IGA (Identity Governance & Administration) |
|---|---|---|
| Primary Focus | Secure, monitor, and control privileged access (admins, root, domain accounts). | Manage identity lifecycle, entitlements, and compliance for all users. |
| Scope | High-value accounts, session management, password vaulting, just-in-time access. | Enterprise-wide users, roles, entitlements, certification, and audit. |
| Strengths | Prevents credential theft abuse, records privileged sessions, enforces JIT least privilege. | Ensures least privilege at scale, automates joiner/mover/leaver processes, detects toxic combinations. |
| Deployment | Vaults, session proxies, credential brokers, privilege elevation tools. | Role-based access control (RBAC), access reviews, policy enforcement. |
| Vendors | CyberArk, Delinea, BeyondTrust, One Identity PAM. | SailPoint, Saviynt, Oracle IGA, One Identity IGA. |
Attack Scenario Example
Without PAM/IGA
-
Attacker steals valid domain admin creds.
-
Uses them to dump AD, pivot laterally.
-
Excessive entitlements in IGA allow access to finance + HR data.
-
No alerts → breach escalates to full ransomware deployment.
With PAM + IGA
-
IGA ensures admin account is time-bound and certified (no stale access).
-
PAM vaults credentials, requires check-out, enforces session recording.
-
If attacker attempts abuse, alerts trigger on abnormal commands.
-
Incident contained → lateral movement blocked.
CyberDudeBivash Best Practices
PAM Quick Wins
-
Vault all privileged credentials (domain admins, root, service accounts).
-
Enable just-in-time (JIT) elevation instead of standing privileges.
-
Record all privileged sessions for forensic playback.
-
Rotate service account passwords frequently.
IGA Quick Wins
-
Automate joiner/mover/leaver workflows to eliminate orphan accounts.
-
Run quarterly access certifications for SOX/GDPR compliance.
-
Enforce role-based access controls (RBAC) and least privilege policies.
-
Detect and resolve toxic combinations (e.g., payroll + approval rights).
Integration Approach
-
Use IGA for enterprise-wide entitlement governance.
-
Use PAM for high-risk privileged sessions.
-
Feed both into SIEM/XDR for unified visibility.
Conclusion
Login is just the beginning. The real battleground is post-login governance.
-
PAM stops attackers from abusing privileged credentials.
-
IGA ensures least privilege and compliance across the identity lifecycle.
Together, they form the backbone of modern Zero Trust.
At CyberDudeBivash, we help organizations unify IAM, PAM, and IGA into a continuous governance model, making post-login exploits a thing of the past.
