ISMS according to ISO 27001 and B3S for the food industry
Your path to secure and efficient compliance
Welcome to your central point of contact for information security management (ISMS) in the energy sector! In the age of digitalization, the requirements are increasing not only for a reliable energy supply, but also for the protection of sensitive information and critical infrastructures(KRITIS). To meet these challenges, ISO 27019, the IT security catalog and the industry-specific security standard (B3S) are indispensable for energy companies.
Why an ISMS is so important for the energy sector
The energy supply is at the heart of modern societies. Electricity, gas and heating networks must function smoothly – failures or attacks would have serious consequences. The Federal Network Agency therefore requires energy suppliers and network operators to introduce an ISMS in accordance with ISO 27001. ISO 27019, which specifically covers the requirements for industrial control systems (ICS) and processes, also applies to the energy sector.
The IT security catalog and the B3S supplement these standards with industry-specific guidelines for technical and organizational measures. This ensures that operators of critical infrastructures remain up to date both technologically and in their internal processes.
ISO 27019, IT security catalog and B3S - what's behind them?
- ISO 27019: This standard extends ISO 27001 to include energy-specific security requirements. The focus is on secure control and process control systems.
- IT security catalog: This guideline developed by the Federal Network Agency requires electricity and gas network operators to have an ISMS and defines minimum standards for the protection of critical infrastructures.
- B3S Energy: The industry-specific security standard supports energy companies in the implementation of customized security measures, taking into account their specific infrastructure.
The aim of all three sets of rules is to ensure robust and sustainable IT and OT security that meets legal requirements and strengthens the trust of customers and partners.
Challenges for energy suppliers and KRITIS operators
- Legal requirements: Various regulatory authorities (Federal Network Agency, BSI, EU) regularly introduce new requirements and stricter regulations.
- Complex IT and OT landscapes: Energy companies operate highly sensitive SCADA and control systems that require special protective measures.
- Lack of resources: The demand for IT security is constantly growing, while skilled workers are in short supply.
- Interface management: The close interdependence of information security, data protection (EU GDPR) and compliance requires an integrated system.
