NIS2, IEC 62443, and CMMC 2.0: what manufacturers must evidence on credential access


When hackers infiltrated Toyota's supplier network in February 2022, stealing 296GB of technical drawings and blueprints, the attack vector was devastatingly simple: compromised credentials. The automotive giant's announcement that "unauthorised access was gained through a credential-based attack" underscored a harsh reality facing manufacturing executives worldwide—traditional authentication methods are failing at the precise moment when regulatory scrutiny is intensifying.

The manufacturing credential crisis

Manufacturing operations face a unique authentication challenge. Unlike purely digital businesses, industrial environments require seamless access across operational technology (OT) systems, industrial control systems, and traditional IT infrastructure. This complexity creates what security professionals term "credential sprawl"—the proliferation of passwords, API keys, and access tokens across interconnected systems.

The problem extends beyond employee credentials. Manufacturing environments depend on machine-to-machine authentication, third-party supplier access, and contractor credentials that often persist long after projects conclude. Each represents a potential entry point for threat actors seeking to disrupt production lines or steal intellectual property.

Consider the typical manufacturing facility: engineers require access to CAD systems, production managers need visibility into ERP platforms, maintenance technicians access SCADA networks, and suppliers connect to procurement portals. Traditional approaches grant users the ability to create, manage, and remember their own credentials—a model that regulatory frameworks increasingly view as insufficient.

The data behind the threat

Manufacturing has become cybercriminals' preferred target. IBM's 2024 Cost of a Data Breach Report identified manufacturing as the second-most targeted sector, with average breach costs reaching $4.88 million. More critically, 68% of manufacturing breaches involved credential compromise, according to Verizon's 2024 Data Breach Investigations Report.

The frequency is accelerating. Operational technology incidents increased by 2,000% between 2022 and 2023, according to Nozomi Networks' OT/IoT Security Report. Of these, 74% originated from compromised authentication mechanisms rather than sophisticated zero-day exploits.

Regulatory violations carry additional financial impact. Under NIS2, manufacturers face fines up to €10 million or 2% of global turnover. IEC 62443 non-compliance can trigger supply chain exclusion, while CMMC 2.0 violations result in immediate contract termination for defence suppliers.

The human factor compounds these statistics. Proofpoint's 2024 State of the Phish report found that 76% of manufacturing employees fell victim to credential-harvesting attacks, the highest rate among all sectors surveyed.

Why conventional solutions fall short

Identity and Access Management (IAM) platforms promise comprehensive credential governance but operate on a fundamental flaw: they assume users should control their own authentication material. Even sophisticated implementations require employees to create, remember, and input passwords—creating opportunities for credential theft.

Privileged Access Management (PAM) solutions offer credential vaulting for administrative accounts but leave standard user credentials exposed. Manufacturing environments often require elevated access for routine operations, making the distinction between privileged and standard accounts increasingly meaningless.

Single Sign-On (SSO) systems reduce password fatigue but create single points of failure. When hackers compromise SSO credentials, they gain access to all connected systems simultaneously. The 2020 SolarWinds attack demonstrated how SSO compromise can cascade across entire networks.

Multi-Factor Authentication (MFA) adds verification steps but cannot prevent credential theft—it merely complicates the attack process. Sophisticated threat actors routinely bypass MFA through SIM swapping, push notification fatigue, and man-in-the-middle attacks.

Zero Trust architectures promise to verify every access request but still rely on credentials as the initial authentication mechanism. The "never trust, always verify" principle becomes meaningless if verification depends on compromisable credentials.

These solutions share a common weakness: they operate on the principle that identity equals access. This equation—while intuitively logical—creates systemic vulnerability because it places credential control in users' hands.

Redefining credential control

The solution requires separating identity from access control—ensuring organisations retain complete authority over authentication materials. This approach, termed "credential abstraction," prevents users from ever seeing, holding, or managing their own access credentials.

Under this model, organisations generate cryptographically secure credentials, distribute them through encrypted channels, and revoke access without user intervention. Employees authenticate their identity through separate mechanisms while credential validation occurs transparently in the background.

MyCena's patented technology exemplifies this approach. Rather than storing passwords in vaults or requiring users to remember complex passphrases, the system ensures credentials never exist in human-readable form. Users authenticate through biometric verification while encrypted credential packages automatically validate access requests.

This architecture delivers what security professionals term "unphishable authentication"—threat actors cannot steal credentials that users never possess. Social engineering attacks fail because employees have no authentication material to compromise.

For manufacturing environments, this separation proves particularly valuable. Operators can access industrial control systems without managing passwords, contractors receive time-limited access that automatically expires, and machine-to-machine authentication operates without human intervention.

Regulatory compliance implications

NIS2's Article 21 requires "appropriate and proportionate" cybersecurity measures, specifically mentioning authentication controls. Credential abstraction provides auditable evidence that users cannot compromise what they never control.

IEC 62443's security level requirements mandate "authenticated and authorised" access across industrial networks. Traditional password-based systems struggle to demonstrate continuous authorisation—credential abstraction enables real-time access validation without user involvement.

CMMC 2.0's access control requirements under AC.1.001 and AC.1.002 demand systematic authentication management. Organisations using credential abstraction can demonstrate complete access control without relying on user behaviour compliance.

The path forward requires manufacturing executives to reconsider fundamental assumptions about authentication. Regulatory frameworks are moving beyond password complexity requirements toward systemic access control—a shift that demands architectural rather than procedural solutions.

Manufacturing's digital transformation makes this transition inevitable. The question is whether organisations will adapt proactively or react to regulatory enforcement actions.
