OX Protect for Families

Wait what? I thought DNS was just a lookup protocol…

Using DNS to Filter Traffic

• The main purpose of DNS is to turn names like “open-xchange.com” into IP addresses “1.2.3.4”

The basis of OX Protect is DNS Filtering

Lookup “open-xchange.com”

DNS

Answer “62.146.90.68”

• DNS underlies almost all traffic on the Internet

• It is critical to almost every legitimate service

• not just Web but also Email, Chat services, Mobile Apps etc.

• Also critical to almost every malicious service

• DNS is used by the bad guys too

• DNS is also (currently) usually unencrypted

• This is changing with DNS over TLS (and DNS over HTTPS)

• Even then not end-to-end encrypted

DNS is Ubiquitous and Un-Encrypted

Thus DNS is Perfect for Filtering

Lookup “illegaldrugs.tv”

• This allows per-device capabilities, and device-type recognition

• OX currently working with IETF & dnsmasq maintainer

• To standardize the transmission of per-device data including

hostname
