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!

Deep Packet Inspection

The security of your IT network is at its best when it is extensive and multi-layered. With Deep Packet Inspection (DPI), network traffic and the protocols and applications used are inspected and classified down to layer 7 level (data area of the data packet). HTTPS data packets are also identified at a fine granular level using "Encrypted Traffic Analysis". This allows detailed network security policies to be defined and combined with clever application management.
