Information security policy
terranets bw

The availability of relevant information is essential for the quality of work deliverables. terranets bw maintains a transparent information policy that must be combined with appropriate protection of information in accordance with state-of-the-art technology and know-how. To achieve this, suitable information security measures must be taken and continuously developed.

The aim is to protect information held by terranets bw from external and internal threats caused by intentional or accidental actions.

The subject matter of protective measures constitutes all information such as digital data on servers, mobile devices, removable storage media etc. that can be transmitted via networks, information in paper form, printed or handwritten, as well as information that can be passed on verbally or by telephone.

In order to ensure the protection of this information, terranets bw has introduced an Information Security Management System (ISMS) that is continuously updated and developed. For the application  field “Network Control / Network Monitoring“ terranets bw will maintain regular certification based on the IT Security Catalogue standard pursuant to Section 11 (1a) of the Energy Industry Act (EnWG).

Securing reliable and continuous operation of critical infrastructures of the gas transmission system and the underground gas storage facilities is a central aim for ensuring the security of supply for natural gas in Baden-Württemberg and adjacent regions by terranets bw.

PRINCIPLES OF Information security

The Information Security Management System of terranets bw is based on the following principles:

  1. We protect valuable and confidential information belonging to terranets bw and that of our business partners from unauthorised access across all communication interfaces (“confidentiality“).
  2. We protect information from unauthorised changes (“integrity“).
  3. We ensure access to current and necessary information as well as to supporting procedures and systems (“availability“).
  4. We maintain reliable and continuous operation.
  5. We comply with legal and contractual requirements, in particular with the IT Security Catalogue pursuant to Article 11 (1 a) of the Energy Industry Act (EnWG).
  6. Based on annual objective programmes, we have implemented a continuous and sustainable improvement process with identification, evaluation and management of existing information security risks.
  7. Within the framework of the ISMS, all company values are considered, especially in the application field “Network Control / Networking Monitoring“. Company values include for example business processes, information, documents and technologies or infrastructure (control systems, information and telecommunication technology, networks, etc.) as well as company locations and employees.
  8. Our ISMS contributes to protecting ourselves from potential threats to our company values by using technical and organisational measures in an appropriate and economically viable way.
  9. Each one of us treats the information put at our disposal with care; we report any possible threats or weak spots directly to the named places and thus contribute to continuously improving our ISMS.
