Introduction: The Perimeter Didn’t Disappear — It Moved

For decades, cybersecurity strategy revolved around one assumption: if you could protect the network, you could protect the business.

Firewalls were strengthened.
VPNs were expanded.
Perimeters were hardened.

That approach made sense when:

Applications lived on-prem
Users worked from offices
Networks defined trust boundaries

But that world no longer exists.

In 2026, organisations operate in a reality where:

Applications are SaaS-based
Data is distributed across cloud platforms
Users authenticate directly to services
Networks are no longer the control plane

Attackers haven’t adapted by becoming more technical. They’ve adapted by becoming more patient.

They steal credentials.
They reuse access.
They wait.

And that’s why identity has become the most important control point in modern cybersecurity.

The Shift: From Network Security to Identity Security

The most common misconception in cyber today is that identity is just another layer in the stack.

It isn’t.

Identity has replaced the network as the primary decision-making surface for access. Industry analysis confirms that identity-based security is now the cornerstone of Zero Trust architectures, with authentication decisions happening at the service level rather than network perimeter [Source].

Every meaningful security decision now starts with:

Who is this user?
What are they trying to access?
Under what conditions?

If identity controls are weak, everything downstream inherits that weakness.

The Data Confirms It: Breaches Are Identity-Driven

Recent breach analysis consistently shows the same pattern—and the numbers are sobering:

Credential theft surged 160% in 2025, with 1.8 billion credentials compromised in just the first six months of the year [Source].

78% of data breaches now involve unauthorized access—meaning attackers are logging in with valid credentials rather than exploiting technical vulnerabilities [Source].

Credential-based attacks now account for 20% of all breaches globally, representing the fastest-growing attack vector in enterprise environments [Source].

This matters because:

Logging in looks legitimate
Alerts trigger later — if at all
Detection and response take longer

The result isn’t just more breaches—it’s worse breaches. When attackers use valid credentials, they move laterally with impunity, often remaining undetected for months.

Understanding IAM: Access Control at Scale

Identity and Access Management (IAM) is responsible for governing:

Authentication
Authorization
Identity lifecycle

At scale, IAM ensures that:

Users get access quickly
Access aligns to role and context
Access is removed when no longer needed

Core IAM components typically include:

Single Sign-On (SSO) – Centralized authentication across applications
Multi-Factor Authentication (MFA) – Verification beyond passwords
Conditional access – Context-aware authorization based on risk signals
Identity governance – Lifecycle management for joiners, movers, and leavers

IAM answers the fundamental question: “Should this person be allowed in—right now?”

IAM is foundational—but it is not sufficient on its own.

Understanding PAM: Containing Privilege and Risk

Privileged Access Management (PAM) exists to manage the most dangerous identities in any environment.

Privileged identities can:

Change system configurations
Access sensitive data repositories
Bypass normal security controls
Execute commands at infrastructure level

Without PAM:

Privilege becomes permanent
Service accounts go unmonitored
Abuse becomes invisible
Lateral movement accelerates

Modern PAM focuses on:

Just-in-time (JIT) access – Temporary privilege elevation only when needed
Credential vaulting – Secure storage and automated rotation of privileged credentials
Auditable sessions – Recording and monitoring of privileged activities
Least privilege enforcement – Limiting access to the minimum required

PAM answers the critical question: “Once inside, how much damage could this identity do?”

PAM doesn’t slow the business down. It stops small failures from becoming catastrophic ones.

Why IAM Without PAM Fails in Practice

Many organisations stop at IAM and believe the job is done. “We’ve deployed MFA—we’re secure.”

This creates critical blind spots:

Admin accounts with standing access – Permanent elevation that never expires
Third-party elevated permissions – Vendor access that persists beyond project completion
Service accounts that never rotate – Automated credentials unchanged for years
Shadow admin privileges – Elevated access hidden in application layers

These identities become ideal targets. The average window for exploitation after credential exposure is 94 days [Source]—yet many privileged accounts remain static for far longer.

Attackers don’t need persistence exploits when privilege already exists and is never removed.

Identity Sprawl: The Hidden Risk Multiplier

As environments grow and digital transformation accelerates, identity sprawl becomes inevitable:

Identities multiply across platforms
Access accumulates with each role change
Visibility decreases as complexity grows

Without active governance:

Old permissions linger after employees leave or change roles
Privilege expands silently through exception requests
Accountability disappears when ownership is unclear
Service accounts proliferate without central tracking

Industry standards mandate credential rotation every 30-90 days for privileged accounts (PCI DSS, NIST, ISO 27001) [Source], yet compliance often lags reality.

This is how breaches escalate quietly—and why detection often comes too late. By the time anomalous behavior triggers alerts, attackers have already achieved their objectives.

Zero Trust Starts (and Fails) With Identity

Zero Trust is frequently misunderstood as a product or architecture you can purchase.

In reality, it’s a discipline—a set of principles that must be built into operations.

And identity is its foundation [Source].

Zero Trust requires three pillars:

Strong authentication (IAM) – Verify every identity, every time
Least privilege (PAM) – Grant minimal access, time-bound when possible
Continuous validation – Monitor behavior and context constantly

Without IAM and PAM working together:

Authentication becomes meaningless if privilege isn’t controlled
Monitoring can’t detect abuse if access is too broad
Incident response is reactive rather than preventive

Zero Trust isn’t about distrust—it’s about verification at every step. IAM and PAM make that verification possible and enforceable.

Service Accounts: The Most Overlooked Attack Vector

Service accounts represent one of the highest-impact gaps in most IAM/PAM programs.

Why service accounts are dangerous:

They often have elevated privileges across multiple systems
They rarely rotate credentials, sometimes running for years unchanged
They typically bypass MFA entirely for operational convenience
They sit outside normal identity governance, with unclear ownership
They’re hard to monitor—distinguishing normal vs. malicious activity is difficult

Attackers specifically target service accounts because they provide:

Persistent access that doesn’t expire
High privilege without requiring social engineering
Low detection risk due to expected automation patterns

Effective service account management requires:

Automated credential rotation (aligned to compliance windows)
Clear ownership and accountability
Privilege scoping to specific functions
Behavioral monitoring for anomalies

The Australian Context: Regulation, Insurance, and Reality

Australian regulators are increasingly explicit about identity as a risk control surface:

OAIC’s Digital ID Regulatory Strategy focuses explicitly on safe identity verification practices and data handling for digital identity systems [Source].

Cyber insurance underwriters now routinely assess:

MFA coverage across all access points
Privileged access governance and monitoring
Identity lifecycle management maturity
Incident response capability around credential compromise

Regulatory expectations have shifted from reactive breach notification to proactive risk management. Regulators now ask:

Were your controls reasonable given known threats?
Could you evidence governance over privileged access?
Did you monitor and respond to access anomalies?

Boards are no longer comfortable with: “IT has it covered.”

They want evidence. IAM and PAM provide it—through audit trails, access reviews, and governance reporting.

A Practical, Executable Starting Point

You don’t need perfection. You need progress.

If you’re early in your IAM/PAM journey, start here:

1. Enforce MFA Everywhere

No exceptions. This includes:

Admin consoles
VPN access
Cloud platforms
Remote access tools

2. Identify All Privileged Accounts

Map out:

Human admin accounts
Service accounts
Third-party vendor access
Emergency break-glass accounts

3. Remove Standing Privilege

Wherever possible:

Implement just-in-time elevation
Set time-bound access windows
Require approval workflows for privilege requests

4. Implement Credential Rotation

Especially for:

Service accounts
Shared accounts (eliminate where possible)
API keys and tokens

5. Review Access Regularly

Quarterly at minimum:

Validate who still needs access
Remove orphaned accounts
Audit privilege creep
Review third-party access

These steps reduce risk immediately—and provide tangible evidence of governance for regulators and insurers.

Common Mistakes That Undermine IAM/PAM Programs

Treating PAM as a Project, Not a Program

PAM isn’t implemented once and forgotten. It requires:

Ongoing access reviews
Continuous privilege discovery
Policy refinement as environments change

Over-Reliance on Technology Without Governance

Tools don’t solve organizational problems. Effective IAM/PAM requires:

Clear ownership and accountability
Business involvement in access decisions
Integration with HR and change management processes

Ignoring Identity Lifecycle

Access must be tied to employment lifecycle:

Automated provisioning for joiners
Role-based adjustments for movers
Immediate deprovisioning for leavers

No Visibility Into Service Account Usage

Without monitoring:

You can’t distinguish normal vs. abnormal behavior
Compromise remains undetected
Forensics become impossible post-incident

Final Takeaway: Identity Is the Deciding Factor

Cybersecurity outcomes in 2026 are determined less by tools—and more by control.

Identity determines:

How breaches start – Through stolen or compromised credentials
How far they spread – Based on privilege and lateral movement capability
How regulators respond – Whether controls were reasonable and evidenced

If identity is weak, everything else is exposed. Your encryption, your EDR, your SIEM—all become irrelevant if an attacker logs in with valid credentials.

Identity is the real perimeter.

The question isn’t whether to invest in IAM and PAM. It’s whether you can afford not to.

Next Steps

If your organisation is investing in cyber but still unsure whether risk is actually being reduced, it’s time to look at identity properly.
