Is my NAS Secure?
Hello, I am Michael Barnes and have A ReadyNas Duo V2. I have just read the attached http://www.bbc.co.uk/news/technology-28707117 article about security. I am not that technical but want to make sure...
NAT delayed address space exhaustion, but didn't prevent it. IANA delivered its last blocks of addresses to the regional internet registries in February 2011. There are just a a few addresses still unassigned by the RIRs. The North American registry (ARIN) is currently 99.4% allocated. So the IPv4 addresses are essentially all gone.
IPv6 isn't really less secure than IPv4, both depend on the edge router to maintain security. In the case of IPv6, it requires stateful inspection of inbound traffic - but most routers are doing this with IPv4 NAT (at least to some degree).
For instance, NAT with no port forwarding allows two-way traffic to an internet device as long as the NAS initiated the connection (outbound). There is no technical barrier to implementing the same policy with IPv6.
The alternative to IPv6 is carrier-deployed NAT which will create a lot of connectivity issues. IPv6 is a better solution IMO.
