Secure operation solution for network control centres

Protection for your power grids according EnWG

Network control centres belong to the category “safety-critical infrastructures”. In order to eliminate the dangers of outages, and to avoid manipulations of the system’s operability or even interventions into processes by unauthorised persons, you have to make continuous and targeted improvements of you control centre’s IT security.

As a specialist for telecontrol, control and automation systems as well as a supplier of turnkey plants, VIVAVIS AG is happy to support you on the basis of its many years of know-how in consulting and implementing measures to enhance your IT security. With regard to IT security, we support you in the introduction of the security catalog and offer you ready-made solutions to meet the measures required therein in accordance with DIN ISO/IEC 27002 and 27019.

Penetration test: Documentation of network security according to the state of the art; BSI-listed test tool; a wide range of attack scenarios with more than 80,000 tests etc.
Back-up and Recovery
Development of data security concepts, such as 3-2-1 procedure, preparation of technical documentation, preparation of system description/back-up procedure
Implementation of a reliable back-up strategy
Plans for disaster recovery: Definition of different scenarios (hardware failure, virus attack etc.), development and documentation of the recovery process, in consideration of time and financial aspects.
Installation of a virus scanner with current signatures, concept creation and implementation, for servers and end devices in the ICS network; update and reporting process
Logging and Monitoring
Log management: Logging and auditing concept
Installation of central LOG servers that centrally consolidate the log files of all systems.
Utilisation of monitoring systems for supervision of the network communication
Detection of Attacks
The IT Security Act 2.0 (ITSiG 2.0) specifies the measures that are essential for the efficient and effective improvement of cyber security. According to this Act, the operators of critical infrastructures are required to install a system to detect cyber attacks by 01 May 2023. The IRMA® system matches the ITSiG requirements for the owners of critical infrastructures; it can be integrated into systems to detect attacks on IT systems. From the beginning, IRMA® meets the recommendations of BSICS134 (Cyber Security Recommendation by the Federal Office for Security/BSI) for the monitoring and detection of anomalies in production networks, as well as the BSI guideline for the introduction of Intrusion Detection systems.

Your benefits for secure network control technology



The first goal in the protection of IT systems is confidentiality. With respect to information security, “confidentiality” is understood to mean that data may only be viewed, edited and managed by persons that are properly authorised to do so. Confidentiality means that access to you sensitive information is protected, preventing misuse of this data through unauthorised persons.


“Integrity” means that the undetected modification of data must not be possible at any time. Hence, integrity comprises of both data integrity and system integrity. Data integrity ensures the continuous correctness of data. Any data modification can be completely reproduced. System integrity ensures the uninterrupted correct functioning of the system and its subordinate components.


Operation of IRMA® in a hardened system and in a redundant or maybe even double redundancy makes sure that your systems operate without interruption as far as this is possible.
Detection of Attacks

Detection of Attacks

If, despite all precautions, an internal or external attacker obtains unauthorised access to the system, this attack is detected by the respective systems (attack detection, monitoring, logging), then documented and an alarm is sent to the operator. Ideally, such attack attempts are attempted early enough to prevent damage.
