What is the primary objective of **NIS2**?

**The primary objective of NIS2 is to establish a high common level of cybersecurity and resilience across EU member states by strengthening critical infrastructure and digital services against cyber threats.** It expands upon the original NIS Directive through a size-cap rule applying to medium and large entities in sectors like energy, transport, health, digital infrastructure, postal services, waste management, and food production, mandating risk management, incident reporting, supply chain security, and cross-border cooperation.

Who is legally or professionally required to comply with **NIS2**?

**NIS2 applies to all medium-sized and large entities classified as 'essential' or 'important' within specified EU sectors.** Essential entities typically have 250+ employees, €50M+ annual turnover, or €43M+ balance sheet; important entities have 50+ employees, €10M+ annual turnover, or €10M+ balance sheet. Criticality can override size if an entity is a sole provider of vital services; coverage includes public administration, space, cloud computing, and online marketplaces, with member states transposing by October 17, 2024.

Does **NIS2** require an external audit or third-party certification?

**NIS2 does not mandate external audits or third-party certification but empowers national authorities for supervision, including spot checks and real-time evidence demands.** Entities must register with central authorities, providing details like name, contacts, sector, and operating states; compliance emphasizes continuous assurance via dynamic risk registers, incident response proofs, and supply chain oversight rather than formal certifications.

How often should an assessment for **NIS2** be performed?

**NIS2 requires ongoing, continuous risk assessments rather than fixed intervals, with dynamic updates such as quarterly risk registers and asset inventories.** Organizations must maintain real-time evidence of cybersecurity measures, including OT/IT assets, supply chain risks, and mitigations, to support live spot checks by authorities like national CSIRTs and ENISA.

What are the consequences of non-compliance with **NIS2**?

**Non-compliance with NIS2 incurs fines up to €10 million or 2% of total global annual turnover for essential entities, and €7 million or 1.4% for important entities.** Additional penalties include business suspension, personal liability for senior management, and enforcement by national authorities, with measures effective from October 18, 2024, following transposition.

An **NIS2** be mapped to other international frameworks?

**Yes, EU member states incorporate standards like ISO 27001, NIST CSF, and ENISA guidelines into national NIS2 frameworks to facilitate mapping and compliance.** This alignment supports risk management, incident handling, and governance without direct equivalence, aiding organizations in leveraging existing controls for NIS2's all-hazards approach.

What is the first step to begin implementing **NIS2**?

**The first step to implement NIS2 is to determine applicability by assessing entity size, sector, and criticality against the size-cap rule.** Conduct a gap analysis of current risk management, register with national authorities if required, and establish governance with senior management accountability for cybersecurity measures and incident reporting procedures.

What is the primary objective of **NERC CIP**?

**NERC CIP standards mandate cybersecurity and physical security controls to protect the Bulk Electric System (BES) against compromise that could cause misoperation or instability.** Developed by the North American Electric Reliability Corporation (NERC), the suite (CIP-002 through CIP-014) requires responsible entities to identify and categorize BES Cyber Systems by impact level (High, Medium, Low) and apply tiered controls including perimeters (CIP-005/006), system hardening (CIP-007), and incident response (CIP-008).

Who is legally or professionally required to comply with **NERC CIP**?

**NERC CIP applies to registered responsible entities owning or operating BES Cyber Systems, including Balancing Authorities, Generator Owners/Operators, Transmission Owners/Operators, and limited Distribution Providers with BES functions like ≥300 MW UFLS/UVLS systems.** Enforcement occurs via NERC Regional Entities and FERC in the U.S., with exemptions for nuclear-regulated facilities under NRC or Canadian Nuclear Safety Commission.

Does **NERC CIP** require an external audit or third-party certification?

**NERC CIP mandates compliance audits by NERC Regional Entities, typically annual or on a 3-6 year cycle, with 3-5 days on-site plus evidence review.** No third-party certification exists; entities self-report via CMEP, retaining evidence for 3 years. Audits verify scoping (CIP-002), policies (CIP-003), and controls through documentation, logs, and interviews.

How often should an assessment for **NERC CIP** be performed?

**NERC CIP requires recurring assessments including vulnerability assessments every 15 months (paper) or 36 months (active testing for High Impact), configuration monitoring every 35 days, and policy/training reviews every 15 months.** Incident response plans must be tested every 15 months, with CIP-002 categorizations reviewed periodically by the CIP Senior Manager.

What are the consequences of non-compliance with **NERC CIP**?

**Non-compliance with NERC CIP incurs fines up to $1 million per violation per day, based on Violation Risk Factors (VRF), Severity Levels (VSL), and Sanction Guidelines.** Penalties escalate for repeats or systemic issues, enforced by FERC; potential remediation directives, operating restrictions, and reputational damage follow audit findings.

An **NERC CIP** be mapped to other international frameworks?

**NERC CIP can be mapped to frameworks like IEC 62443 for OT security, but mappings must preserve CIP's BES reliability focus and audit evidence requirements.** No formal crosswalks exist; entities document alignments for efficiency, ensuring CIP cadences (e.g., 35-day patching) and scoping (CIP-002) remain primary.

What is the first step to begin implementing **NERC CIP**?

**The first step is CIP-002 categorization: identify BES Cyber Systems and classify them as High, Medium, or Low Impact using bright-line criteria.** Appoint a CIP Senior Manager, document the inventory with approvals, and review every 15 months to define control scope for subsequent standards.
