DIGI Távközlési és Szolgáltató Kft. classification and mapping of critical system elements

Case study

Classification and matching of the critical system element DIGI Távközlési és Szolgáltató Ltd. with the assistance of FORTIX Consulting Ltd.

In the modern telecommunications world, information security and cyber security are key issues. The cooperation between FORTIX and DIGI in this field has been flourishing since 2015 and they have implemented several successful projects together. In this case study, we present a particularly important project dealing with the classification and compliance of critical system elements of DIGI, one of Hungary’s largest telecom operators.

The challenge

The authority has classified DIGI as a national critical infrastructure operator for several infrastructure elements, and thus they are subject to BM Decree 41/2015. The affected system elements included critical assets such as network routers, telephone exchanges, satellite and cable TV servers and related IT infrastructure servers.

The solution

During the implementation of the project, our experts carried out the following tasks:

Conduct interviews on critical system elements and then determine the expected class according to the OVI table.
Populate the OVI table with the general information security requirements that have been met.
System-specific collection of information on the fulfilled requirements of the system components, through interviews with the specialised areas.
Verification and consolidation of the data collected.
Classification based on the protection measures for the organisation, defining the expected and achieved levels when completing the CSI table.
Classification: we had to classify all vital system elements. The first step was to determine the expected class and then to assess the completed class during the interviews. Based on the deviations, an action plan was prepared for the client.

Result

At the end of the project, the OVI forms per system element, the OVI form and a management project summary were delivered. The cooperation between FORTIX and DIGI in this area has also been successful and as a result of the project, the classification of DIGI’s system elements has been completed and the outstanding requirements have been identified, which will contribute to the improvement of the company’s information security.

Conclusion

The successful collaboration between FORTIX and DIGI demonstrates not only the success of a project, but also the depth of expertise and commitment we can provide in the area of information security. In today’s telecommunications and IT world, security challenges are increasingly complex and companies need a trusted partner – like FORTIX – to meet these challenges. The success of the DIGI project shows that FORTIX is able to respond efficiently and professionally to the most complex security challenges. For other companies, this is a clear indication that FORTIX is one of the best choices when looking for expertise and reliability in information security and cybersecurity.

“Working with FORTIX, we have had the opportunity to work with excellent professionals who have distinguished themselves not only for their professionalism, but also for their reliability and precision. At every stage of the project, we felt the expertise and commitment that FORTIX represents. Deadlines were met to the letter and everything went according to plan. With their help, we were able to complete a complex and challenging project with relative ease and without a hitch. I would highly recommend FORTIX to any company looking for a high level of information security expertise and a reliable partner.”
