Network security

From fundamentals to hands-on

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!

Client management via user databases

In accordance with the new remote access security standard "Zero Trust", user authentication for network access should be structured and detailed. However, this does not have to be cumbersome: If a central user database ("identity provider", e.g. an Active Directory such as Microsoft Entra ID (formerly Azure AD)) is used, LANCOM Trusted Access, for example, can be used to provide user groups taken over from the identity provider with individual access rights to the permitted applications. The validity of authentications can also be limited centrally and effortlessly, and clients can be blocked manually or automatically. Thanks to the integrated user management in the LANCOM Management Cloud, this is even possible for small companies without a central user database.

NIS2 is affecting companies and institutions across Europe. After all, anyone affected by the directive who cannot demonstrate certain cyber security standards and risk management measures in the future could face heavy fines.

There is advice from many sources on how to prepare. However, it is often difficult to know whether this advice is legally sound.
