Providing network security is one of the most important tasks in today's Internet. Unfortunately, many users are not able to protect themselves and their networks. Therefore, the authors present a novel security concept to protect users by providing security measures at the Internet Service Provider (ISP) level. Already now, ISP are using different security measures, e.g. Virtual Local Area Network tags, MAC limitation, or MAC address translation. Their approach extends these security measures by a packet filter firewall and a deep packet inspection engine.
