Secu3: IPv6 Security

The days of version 4 (IPv4) of the internet protocol will soon be numbered. Many areas are therefore already using version 6 (IPv6) of the internet protocol. Current operating systems often automatically support this protocol without the need for interaction on the part of the user. This situation harbors a danger in that security gaps may occur here. IT officers are often unaware of these security gaps because they do not know about them. Nevertheless, data traffic should be secured with IPv6 in the same way as with IPv4.
