By definition, network security describes the technical and organizational protection of the internal IT infrastructure with all its data, systems, devices, and applications to enable secure digitalization. These security mechanisms not only protect the data center, but also all locations and the cloud itself. Effective network security fends off unauthorized access, data manipulation or data theft with blackmail, system paralysis (DDoS attacks), and other damage caused by hackers, malware, and viruses.
It ensures that data is exchanged confidentially and with integrity and is always available via VPN (Virtual Private Networks) or ZTNA (Zero Trust Network Access). However, secure networks are created primarily through comprehensive information on network security and network protection, as well as targeted measures to enforce cyber protection policies at all levels. The best way to get started right now is with LANCOM insider knowledge on the subject of network security!
Local editing of LMC objects
With LCOS FX 11.2, the management of security policies becomes significantly more flexible: Certain firewall objects defined in the LANCOM Management Cloud (LMC) can now be modified directly on the firewall locally. This allows administrators to selectively extend security-related functions such as NAT without having to create redundant objects. Centrally defined parameters remain protected and unchangeable, ensuring consistent enforcement of security policies. At the same time, local adjustments can be made flexibly to meet specific on-site requirements. If an object is removed centrally, it is automatically deleted from the firewall as well – transparently documented in the audit log. This creates a balanced combination of centrally managed network security and local adaptability – providing greater control, efficiency, and traceability in operation.
Network security according to NIS2
The EU has given network security a new, even higher priority with the new NIS2 directive: Because without state-of-the-art cybersecurity, attacks on critical infrastructure can have serious consequences for society and the economy. NIS2 requires many adjustments for some companies. We show you to whom NIS2 applies, what is required, and how to implement the policy.
Network security is primarily based on a good understanding of your own network and security technology. Which devices are in use? Are they state of the art and well maintained? Are all configurations correct?
