Netzwerksicherheit zuhause: Wie wichtig ist Heimnetzwerk-Sicherheit?

Network security is immensely important today, even at home - for people who are not very tech-savvy. Most Internet users know little about network security at home. Often, knowledge about home network security is limited to consciously looking out for the green lock to communicate only with trustworthy websites. However, the green lock only means that there is encryption between your computer and the website and not trusted website content. Hackers, for example, combine freely available certificates for SSL encryption with the /.well-known/ directory to embed phishing in websites. Also, every Ethernet port and every WLAN signal offers thousands of entry points. So if a hole can be closed, there are numerous other ways to access the network resources of the home network. If you want to know whether your router and the firewall program running on it are shielding the home network well against potential attackers, you should test network security and start a network check. General tips for network security at home are:

• Reduce complexity for home network security - the simpler, the more secure - remove what is not necessary
• Know how to update a device with security updates
• Know how to configure a device with available security settings
• Number of data that a device actually shares with an online service
• Some home routers allow a Wi-Fi network to be split into two networks that can be managed separately. This allows IoT home devices to be placed on one guest network and work computers on another network to increase the security of important data.
• Activate client isolation to shield devices in the network from each other
• Beware of phishing emails for network security at home
• Know who to contact in the event of a security problem, e.g. technical support
• Comprehensive approach to home network security - inside and outside, because security is not an appliance that is installed once and successfully implemented, but an ongoing process.
• Learning from companies
• Test the network - only those who know the weak points can rectify them
• Possibly use free programs for network management

The correct configuration for network security at home is particularly important for WLAN security:

• Create individual administrator access for home network security
• Select WPA2 as the encryption method for sufficient WLAN security
• Create a secure WLAN password
• specify a non-identifiable network name
• Switch on automatic firmware update for WLAN security

For network security at home, the wireless access point should be configured carefully, additional security components such as IEEE 802.1X, a firewall or an intrusion detection system should be installed, work and guest networks should be operated separately and the up-to-dateness and performance of the network components should be checked regularly. This creates a very good basis for home network security.
