CIP Misclassification: Detection & Correction

Foreword

Foreword

This professional reference is one of a series Energy Compliance, Inc. publishes for registered entities and the people who run their compliance programs.

I’ve spent more than thirty years on every side of the bulk electric system. I’ve operated control centers as a Reliability Coordinator, Transmission Operator, and Power System Operator. I’ve audited grid facilities and signed off on findings as a senior compliance auditor. I’ve worked enforcement matters from inside the regulator’s process. For the last several years I’ve advised registered entities directly through the firm I founded.

The entities that do reliability well share a common habit. They take the standards seriously without confusing them with reliability itself. They know that a NERC Reliability Standard is a floor, not a ceiling. They know that compliance is something an auditor evaluates, but reliability is something a system either delivers or doesn’t. They prepare for audits by building programs that survive real questions, not binders that look thick.

That’s the perspective these references try to share. Each one focuses on a single topic. A standard family, an operational function, a regulatory framework, or an emerging industry challenge. Each one walks through how the topic actually works.

These references are written for the compliance manager who wants to understand the system, not just memorize requirements. For the legal counsel who has to brief a board honestly. For the senior operator who’s been told that compliance and reliability are the same thing and suspects they aren’t. And for the new compliance hire who got handed a binder and told good luck.

These references aren’t marketing material disguised as content. They’re the result of three decades of doing this work and watching it succeed and fail. I’ve written them in the same voice I use in a control room or in front of a Regional Entity audit team. Direct, evidence-grounded, honest about what the standards do and do not require.

Energy Compliance exists because most of the consulting offered to registered entities today is structured for billable hours rather than for outcomes. Every engagement is led by one senior practitioner. We don’t bring five people to a meeting that needs one. We automate the work that should be automated. We apply senior judgment to the work that requires it. If that approach matches what you’re looking for in a compliance partner, the back of this reference has our contact information.

EC-WP-204 CIP Misclassification

Chapter 1

Why Misclassification Keeps Happening

To understand why misclassification persists despite years of CIP enforcement and extensive industry guidance, it is necessary to understand the conditions under which classification decisions are made. Classification is not a one-time exercise. It is an ongoing obligation that must be performed against a changing operational environment, and the processes most entities use to fulfill that obligation are not designed for continuous accuracy.

The Point-in-Time Trap

Most entities perform their CIP-002 asset identification and classification during a defined period, typically an annual review or in response to a significant change, and then treat the resulting inventory as authoritative until the next scheduled review. This approach has a fundamental vulnerability: operational environments change continuously, and classification decisions that were correct when made can become incorrect without triggering any formal review process.

A substation that did not meet Medium Impact thresholds when the inventory was last reviewed may meet them today if capacity additions have pushed it above a threshold. A backup control center that was correctly excluded may have been brought online as a primary operational resource during a system reconfiguration. A generation facility may have undergone an upgrade that changes its relationship to BES reliability functions. None of these changes automatically triggers a CIP-002 review under most entities' internal processes, which means the classification inventory accumulates errors between formal review cycles.

The Legacy Decision Problem

The most consequential source of misclassification is not new decisions made incorrectly. It is old decisions that were correct at the time and have never been revisited. In entities with mature operational histories, CIP classification inventories often contain determinations that were made in earlier versions of the standard, under different bright-line criteria, by personnel who are no longer with

the organization, and that have been carried forward through successive inventory updates without substantive re-evaluation.

This is where misclassification becomes genuinely dangerous. A classification decision made under CIP-002 Version 3 may not be valid under CIP-002 Version 6. An exclusion determination that was defensible under earlier thresholds may not survive scrutiny under current criteria. When an auditor asks for the documentation supporting a Low Impact classification and the entity produces a memorandum from eight years ago that references superseded standard language, the classification is essentially undocumented under current requirements.

The Cognitive Bias That Drives Under-Classification

There is a consistent directional bias in misclassification: entities more frequently classify systems at a lower impact level than warranted, rather than a higher one. This is not accidental. Higher impact classification triggers more requirements, more controls, more evidence obligations, and more audit exposure. The institutional incentive structure points toward lower classification wherever the criteria permit ambiguity.

That bias manifests most commonly as over-application of exclusions. CIP-002 includes specific exclusion provisions, systems that meet certain criteria may be excluded from classification even if they would otherwise qualify. These exclusions are narrow and specific. In practice, entities sometimes apply them broadly, excluding systems based on general operational characteristics rather than the specific criteria the standard establishes. The result is a classification inventory that appears complete and defensible on its face but that excludes assets that a careful application of the criteria would include.

Organizational Gaps That Create Blind Spots

Classification accuracy depends on visibility, the ability to identify every asset that performs a reliability function and evaluate it against classification criteria. In most entities, that visibility requires input from multiple organizational functions: operations, engineering, IT, and compliance. When those functions do not share a common asset inventory, when systems are added to the operational environment without notifying the compliance team, or when engineering changes are implemented without a formal change assessment process, the classification inventory develops blind spots.

The blind spot problem is most acute in entities that have grown through acquisition, merger, or significant infrastructure expansion. Assets acquired through corporate transactions may have been classified under different methodologies or different versions of the standard. Facilities that were added to the BES through interconnection agreements may not have been evaluated for CIP classification at the

time of interconnection. The compliance team that is responsible for maintaining the classification inventory may not have visibility into these assets at all.

End-of-Chapter Summary

Misclassification persists because the operational environments in which classification must be maintained are dynamic, the organizational processes most entities use to maintain classification are not, and the institutional incentive structure consistently favors lower classification wherever the criteria permit ambiguity. Correcting these conditions requires process discipline that most entities do not have by default and must deliberately build.

FROM THE FIELD

Misclassification is the most common Self-Reported violation in CIP. It's also the most preventable. Both facts are connected.

Classification is not a one-time exercise. The operating environment changes; the classification has to keep up. Programs that classified once at registration and stopped have already drifted.

The conditions that produce misclassification — turnover, system additions, organizational restructuring — are the conditions of normal utility operations. Classification has to be designed to survive them.

Chapter 2

The CIP-002 Classification Framework in Plain Terms

CIP-002 is the foundational standard in the CIP framework. Every subsequent requirement, from CIP-003 governance controls through CIP-011 information protection, is triggered by the classification determinations made under CIP-002. Getting classification right is not one compliance obligation among many. It is the obligation on which all others depend.

The Identification Sequence Cannot Be Shortcut

CIP-002 establishes a specific sequence for asset identification and classification that must be followed in order. The sequence begins with identifying BES Assets, the facilities and systems that meet the NERC definition of the Bulk Electric System. It then requires identifying Cyber Assets within those BES Assets that perform reliability functions. Those Cyber Assets are then grouped into BES Cyber Systems based on the reliability tasks they collectively perform. Finally, the BES Cyber System is evaluated against the High, Medium, and Low Impact criteria.

This sequence matters because shortcutting it produces classification errors. Entities that begin with a list of known control systems and work backward to determine whether they qualify as BES Cyber Assets will miss Cyber Assets that are not on the initial list but that perform reliability functions. Entities that classify individual Cyber Assets rather than BES Cyber Systems will misapply the impact criteria, which are defined at the system level, not the asset level. The sequence is not bureaucratic formality, it is the structure that makes classification reliable.

What the Bright-Line Criteria Actually Say

For High Impact, the bright-line criteria identify primary control centers performing RC, BA, or TOP functions above defined capacity thresholds, and certain generation control systems. These criteria are not subject to entity judgment, a facility either meets them or it does not. The classification that follows is mandatory.

For Medium Impact, the criteria cover a broader range of facilities: generation resources above defined capacity thresholds, certain transmission substations based on voltage and configuration, and backup

control centers. The Medium Impact criteria include more conditional language than the High Impact criteria, which creates more opportunities for interpretation, and more opportunities for misinterpretation.

The Low Impact category is defined by exclusion: BES Cyber Systems that do not meet the criteria for High or Medium Impact are Low Impact. This means that Low Impact is not a classification determination in the same sense as High or Medium, it is the residual category for everything that does not qualify for a higher tier. Entities that treat Low Impact as a category that requires affirmative justification, rather than the default for unqualified systems, will approach classification more carefully.

The Exclusion Provisions: Narrow by Design

CIP-002 includes explicit exclusion provisions for certain system types and configurations. These exclusions exist because the standard's drafters recognized that some systems meeting the technical criteria for classification do not materially affect BES reliability in the ways the CIP framework is designed to address. The exclusions are therefore narrow and specific, tied to defined technical conditions, not to general operational characteristics.

The most frequently misapplied exclusion is the low impact exclusion for systems at facilities that would otherwise meet Medium Impact criteria. Entities sometimes treat this exclusion as available whenever a system's operational role seems limited, even when the specific exclusion criteria are not met. Auditors examining the basis for Low Impact classifications will look specifically at whether applicable exclusions were correctly applied, and incorrectly claimed exclusions are among the most common findings in classification-related enforcement actions.

End-of-Chapter Summary

CIP-002 is precise where entities most commonly want it to be flexible, and flexible where entities most commonly want precision. The identification sequence is mandatory and must be followed in order. The High Impact criteria are objective and do not permit entity judgment. The Medium Impact criteria require careful application of specific language. The exclusion provisions are narrow and cannot be stretched to cover systems that do not meet their specific conditions.

FROM THE FIELD

Classification under CIP-002 is the standard everything else hangs from. Every other CIP requirement applies based on the classification. Get it wrong and the entire program is misaligned.

The identification sequence in CIP-002 cannot be shortcut. The standard prescribes a specific order: identify BES Cyber Assets, group into BES Cyber Systems, classify by impact. Programs that compress the sequence make errors at the boundary.

Chapter 3

Where Entities Get Classification Wrong

Classification errors are not randomly distributed across the CIP-002 criteria. They cluster around specific provisions, specific system types, and specific organizational conditions. Understanding where classification breaks down is the first step toward preventing it.

The Control Center Boundary Problem

Primary control centers are among the most clearly defined High Impact assets in CIP-002. Yet control center classification generates a disproportionate share of enforcement findings, primarily because the boundary of what constitutes the control center is frequently defined too narrowly.

A primary control center is not just the main control room and the systems directly visible to operators. It includes the Cyber Assets that support the reliability functions performed at the center: the data historians, the real-time analysis tools, the communication systems that connect the control center to field devices, and the systems that provide situational awareness inputs to the operators. Entities that classify the SCADA front-end and the energy management system but exclude the supporting data infrastructure on the basis that those systems are 'IT' rather than 'OT' are misclassifying by scope exclusion.

Generation: The Capacity Threshold Trap

Generation resources above defined capacity thresholds are subject to Medium Impact classification for the control systems that perform the Generator Owner and Generator Operator functions at those facilities. This is an area where classification errors are extremely common, particularly among entities that operate generation portfolios with units of varying sizes.

The threshold applies at the aggregate level for certain configurations, not just to individual units. A facility with multiple smaller units that individually fall below the threshold but whose combined capacity exceeds it may trigger classification for the control systems that manage the facility collectively. Entities that evaluate each unit independently rather than considering aggregate capacity will consistently under-classify generation control systems.

A related error occurs when entities classify the generation unit itself rather than the control systems that perform reliability functions. CIP-002 classifies BES Cyber Systems, the software and hardware that perform reliability tasks, not the physical generation asset. The turbine is not a BES Cyber Asset. The control system that monitors and manages the turbine's output in support of the Generator Operator function may well be.

Transmission Substations: The Configuration Complexity

Transmission substation classification under the Medium Impact criteria depends on specific voltage configurations, the number of transmission lines served, and the functional role of the substation in the transmission network. These criteria are more configuration-dependent than the generation thresholds, which means that classification accuracy depends on having accurate, current, and detailed knowledge of substation configurations.

This is where engineering-compliance disconnects create the most exposure. The compliance team may maintain a classification inventory based on substation characteristics documented during the last formal review. The engineering team may have made configuration changes, adding transmission lines, modifying bus configurations, installing new protection systems, that change the substation's relationship to the Medium Impact criteria. If those changes are not communicated to the compliance team and evaluated for classification implications, the inventory becomes inaccurate without anyone making a deliberate error.

The 'It's Not BES' Assumption

One of the most consequential misclassification patterns is the blanket assumption that a system is not a BES Cyber Asset because it is located at a distribution voltage facility, managed by an IT organization rather than an operations organization, or labeled as a 'business system' rather than an 'operational technology system.' None of these characteristics determines BES Cyber Asset status. What determines it is whether the system, if rendered unavailable, degraded, or misused, would within 15 minutes adversely impact one or more BES facilities or functions.

That functional test catches systems that organizational categories miss. A historian that aggregates real time operational data from multiple substations and feeds it to the control center may not look like a BES Cyber Asset from an IT perspective. If its loss would degrade the control center's situational awareness in ways that affect the operator's ability to manage BES reliability functions in real time, it may well be one. The classification analysis begins with function, not with organizational location or system label.

End-of-Chapter Summary

Classification errors cluster around the control center boundary, generation capacity thresholds, transmission substation configurations, and the functional test for BES Cyber Asset status. In each of these areas, the common failure mode is the same: applying a simpler rule than the standard requires, either because the standard's specific language is not well understood or because the operational information necessary to apply it correctly is not available to the people doing the classification.

FROM THE FIELD

Classification errors aren't random. They cluster around specific provisions, specific system types, and specific organizational conditions. Knowing the cluster is preventing the error.

The BES Cyber System definition is where most misclassification originates. The definition includes operational logic the asset inventory alone can't surface.

Organizational conditions matter. A classification done by a vendor and never reviewed by the registered entity is a classification waiting to be wrong.

Chapter 4

How Auditors Identify Misclassification

Auditors do not begin a CIP audit by taking an entity's classification inventory at face value. They approach classification with a specific set of investigative techniques designed to surface both direct misclassification and the conditions that produce it. Understanding those techniques is essential for entities that want to identify their own exposure before auditors do.

The Registration Cross-Reference

Every registered entity has a NERC functional registration that describes the reliability functions it performs and the facilities at which it performs them. Auditors routinely cross-reference the CIP-002 asset inventory against the entity's registration profile. If an entity is registered as a Transmission Operator with operational authority over substations meeting Medium Impact criteria, and those substations do not appear in the CIP-002 inventory at the appropriate impact level, the discrepancy is immediately apparent.

This cross-reference catches one of the most common misclassification patterns: entities that maintain accurate functional registrations but have not connected their registration profile to their classification obligations. The registration tells auditors what functions the entity performs. The CIP-002 inventory should reflect the systems that support those functions. Gaps between the two are the starting point for classification inquiries.

The Facility Walk and the Inventory

For in-person audits, auditors have the ability to walk the facility, to observe what systems are present, what they are connected to, and how they are configured, and compare those observations against the classification inventory and the documented ESP architecture. Systems that appear in the facility but not in the inventory, connections that appear in the operational environment but not in the network documentation, and equipment configurations that differ from the documented baselines all generate audit questions.

This technique is particularly effective at surfaces the scope exclusion errors described in the previous chapter. An auditor who observes a historian rack in a control center environment and notes that it does not appear in the ESP documentation or the asset inventory will ask direct questions about why it was excluded. If the answer is 'we considered it an IT system,' the auditor will evaluate whether the system's function meets the BES Cyber Asset definition regardless of how the entity categorizes it internally.

Pattern Recognition Across the Evidence Package

Experienced auditors read evidence packages as narratives, not as checklists. The evidence produced for CIP-007 patch management will reference specific systems. The evidence produced for CIP-005 ESP documentation will describe specific network architectures. The evidence produced for CIP-010 baseline configurations will document specific Cyber Assets. When those three evidence streams reference different populations of systems, when assets that appear in one control area's evidence do not appear in another's, the discrepancy signals a classification or scoping problem.

This pattern recognition approach catches misclassifications that would not be visible from examining any single control area's evidence in isolation. An entity that has correctly documented its ESP and access controls but whose patch management records cover a different set of systems than the ESP documentation is presenting evidence of an inconsistency that auditors will resolve by asking which population of systems is correct, and then evaluating the classification of the systems that appear in one evidence stream but not the other.

The Self-Report as a Red Flag

When entities self-report misclassification violations, the self-report itself becomes a data point for auditors evaluating the maturity of the entity's CIP program. A self-report that demonstrates a thorough internal review process, precise identification of the classification error, clear root cause analysis, and well-developed corrective actions presents differently than a self-report that is vague about scope, uncertain about the period of exposure, and thin on corrective action detail.

Auditors examining a self-reported misclassification will look at whether the corrective actions address the root cause, the process failure that allowed the misclassification to occur, or only the immediate error. Corrective actions that fix the specific misclassified asset without addressing the process that produced the error are a signal that the same failure mode is likely producing other errors that have not yet been identified.

End-of-Chapter Summary

Auditors identify misclassification through cross-referencing functional registration against classification inventories, direct facility observation, pattern recognition across evidence packages, and evaluation of self-report quality. Entities that want to identify misclassification before auditors do should apply the same techniques to their own programs, starting with the registration cross-reference, which requires no technical investigation and consistently surfaces the most consequential gaps.

FROM THE FIELD

The auditor doesn't accept your classification at face value. They reconstruct it from the asset inventory, the system architecture, and the operational descriptions you provided.

Auditors look for the things classification documentation typically misses: undocumented control paths, dual-purpose assets, and changes that weren't reflected in the classification.

Knowing the auditor's investigative pattern lets you self-audit before they arrive. The patterns are reproducible; the surprises shouldn't be.

Chapter 5

Correction Strategy: Reclassification Without Panic

Discovering a misclassification, whether through internal review, third-party assessment, or audit preparation, triggers a sequence of decisions that will determine both the compliance outcome and the enforcement exposure. How an entity manages the correction process matters as much as the correction itself.

Scope the Exposure Before You Disclose

The first step when a potential misclassification is identified is to scope the exposure precisely before any disclosure decision is made. That means determining when the misclassification began, not when it was discovered, but when the system should have been classified at a higher impact level. It means identifying every CIP requirement that applied during the exposure period that was not implemented. And it means assessing whether any of those requirement gaps created material control deficiencies, periods during which systems that should have been protected were not.

This scoping work is essential for two reasons. First, it determines whether the entity has a self-reporting obligation under the CMEP and what the timeframe for that obligation is. Second, it defines the corrective action scope. An entity that discloses a misclassification without having scoped the full exposure may find, in the course of the enforcement process, that the exposure is larger than the disclosure represented, a situation that is significantly more damaging to the entity's credibility with the Regional Entity than an initially larger but complete disclosure.

Self-Reporting: The Decision and the Document

The decision to self-report a potential violation is consequential. Self-reporting is one of the factors that mitigates penalty in NERC's enforcement process, but the mitigation depends on the quality and completeness of the disclosure. A self-report that accurately characterizes the full scope of the exposure, demonstrates that the entity identified the issue through its own compliance monitoring, and presents a credible corrective action plan will be treated differently than one that characterizes the exposure narrowly and presents corrective actions that address only the surface error.

The self-report document itself, the initial notification and any subsequent written submissions, becomes part of the enforcement record. It will be examined by the Regional Entity, potentially by NERC, and in significant cases by FERC. The precision and candor of that document reflects directly on the entity's compliance culture and its relationship with the oversight body.

Corrective Actions That Actually Correct

The most common failure in misclassification corrective actions is addressing the symptom rather than the cause. An entity that responds to a misclassification finding by reclassifying the affected system and implementing the missing controls has fixed the immediate problem. If it has not addressed the process failure that allowed the misclassification to occur, the gap in the change assessment process, the organizational disconnect between engineering and compliance, the absence of a formal periodic classification review, the same failure mode will produce another misclassification.

Regional Entities and NERC evaluate corrective actions not just for whether they address the identified violation but for whether they address the root cause in a way that is likely to prevent recurrence. Corrective actions that demonstrate systemic process improvement, redesigned change assessment workflows, formalized classification review schedules, improved organizational communication, present a qualitatively different picture than corrective actions that simply implement missing controls on the misclassified system.

End-of-Chapter Summary

Misclassification correction requires precision at every step: scoping the full exposure before disclosure, producing a self-report that accurately characterizes the scope and presents credible corrective actions, and implementing corrective actions that address the root cause rather than just the immediate error. Entities that treat this sequence as a compliance obligation to be minimized will consistently find that the enforcement process probes exactly the dimensions they have handled most casually.

FROM THE FIELD

A misclassification surfaced internally is a different conversation than one surfaced by audit. Internal disclosure changes the enforcement posture, the timeline, and the penalty calculation.

The first step when misclassification is suspected is scope. Define what's wrong, how it affected the program, and what controls were missed. Disclose only after you have the picture.

Speed matters, but not at the cost of accuracy. A correction that's fast but wrong gets re-corrected at the next audit, with worse exposure.

Chapter 6

Building a Classification Program That Stays Accurate

The goal is not to classify correctly once. It is to maintain classification accuracy continuously in an operational environment that changes faster than compliance processes typically adapt. That requires deliberate program design, not more documentation of the same processes, but different processes designed for continuous accuracy rather than point-in-time completeness.

The Change Assessment Process Is the Core Control

The most important single control in a classification program is a change assessment process that evaluates every material operational change for CIP classification implications before the change is implemented. This is the mechanism that catches the configuration changes, capacity additions, and system modifications that would otherwise produce undiscovered misclassifications between formal review cycles.

For a change assessment process to work, it must be integrated into the operational change management workflow, not added as a parallel compliance activity. Changes are approved through the change management process. The CIP classification assessment should be a defined step in that approval process, not a separate compliance review that happens afterward. When the assessment is integrated into change approval, it is performed on every change. When it is a separate process, it is performed on the changes that someone remembered to send to compliance.

The Periodic Classification Review

CIP-002 requires entities to perform a review of their asset inventory at least annually and whenever a change occurs that could affect the classification of a BES Cyber System. In practice, the annual review is often the only review that occurs, which means that changes with classification implications that occur between annual review cycles are not evaluated until the following year's review.

A defensible periodic classification review does more than confirm that the existing inventory is still accurate. It actively tests the inventory against current operational configurations, cross-references the classification inventory against the functional registration profile, and evaluates whether any changes

implemented since the last review affect classification determinations. This is not a passive exercise. It requires active investigation of the operational environment, not just review of existing documentation.

Governance: Who Owns Classification

Classification accuracy is a shared responsibility between the compliance function and the operational and engineering functions that have visibility into the systems being classified. When that shared responsibility is not formalized, when there is no defined ownership, no clear escalation path for potential classification issues, and no accountability for keeping the compliance team informed of operational changes, the classification inventory drifts.

Mature classification programs assign explicit ownership: a compliance team member responsible for maintaining the classification inventory, defined operational contacts responsible for notifying compliance of relevant changes, and a governance process for resolving classification questions that arise between formal review cycles. That structure does not eliminate classification errors, but it creates the organizational conditions under which errors are identified and corrected before they accumulate into enforcement exposure.

End-of-Chapter Summary

A classification program that stays accurate is not a documentation system, it is an operational process integrated into how the entity manages its facilities and systems. The change assessment process catches misclassifications at the moment they would otherwise be created. The periodic review catches misclassifications that accumulated despite the change assessment process. The governance structure ensures that both processes are actually performed. Entities that have all three in place have fundamentally different classification risk profiles than entities that rely on annual inventory updates alone.

Glossary of Terms

Glossary of Terms

BES Cyber Asset: A Cyber Asset that, if rendered unavailable, degraded, or misused, would within 15 minutes of its required operation adversely impact one or more facilities, systems, or equipment which, if destroyed or degraded, would affect the reliable operation of the Bulk Electric System. The 15-minute threshold is not a grace period, it defines the functional test for classification.

BES Cyber System: One or more BES Cyber Assets logically grouped by a responsible entity to perform one or more reliability tasks for a functional entity. Classification under CIP-002 is applied at the system level, not the individual asset level.

Bright-Line Criteria: The objective thresholds in CIP-002 that determine High and Medium Impact classification. Bright-line criteria do not permit entity judgment, a facility either meets them or it does not.

Change Assessment: The process of evaluating a proposed operational or system change for CIP classification implications before the change is implemented. A functional change assessment process is the primary control against classification drift.

Classification Inventory: The documented record of an entity's BES Cyber Systems, their impact classifications, and the basis for each classification determination. The inventory must be accurate as of the current date, not as of the last formal review.

Compliance Monitoring and Enforcement Program (CMEP): The program through which NERC Regional Entities monitor, assess, and enforce compliance with approved Reliability Standards, including CIP-002. Self-reporting obligations under the CMEP are triggered when entities identify potential violations of mandatory standards.

Exclusion: A specific provision in CIP-002 that removes an otherwise qualifying BES Cyber System from classification requirements under defined conditions. Exclusions are narrow and specific, they apply only when their stated conditions are met, not when an entity's general operational judgment suggests lower impact.

High Impact BES Cyber System: A BES Cyber System meeting the High Impact criteria in CIP-002 Attachment 1, including primary control centers performing RC, BA, or TOP functions above defined thresholds.

Misclassification A determination that a BES Cyber System was classified at an incorrect impact level, most commonly, that a system was classified as Low Impact when it should have been classified as Medium or High Impact. Misclassification is treated as a violation of CIP-002 for the period during which the incorrect classification was in effect.

Periodic Review: The CIP-002 requirement to review the BES Cyber System inventory at least annually and whenever a change that could affect classification occurs. A defensible periodic review actively tests the inventory against current configurations rather than confirming existing documentation.

Self-Report: An entity's voluntary disclosure of a potential violation to its Regional Entity. Self-reporting is a mitigating factor in NERC's enforcement process, but its mitigating value depends on the completeness and candor of the disclosure.

Significant Change: A change that could affect the classification of a BES Cyber System and that therefore triggers an obligation to review the classification inventory under CIP-002. Entities must define what constitutes a significant change within their programs.
