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...
(I don't know how this forum feels about necroposting.. this is about a month old, not to terribly old yet.)
I've complained about IPv6 in the past, and this is just another way that IPv6 is going to bite nontechnical people.
NAT has turned out to be a really good solution to IPv4 address space exhaustion, and NAT offers benefits for people that have no idea what they're doing. Firewall setup is not too critical with NAT, because if ports are not forwarded, then your devices cannot be reached externally.
It's as simple as that. No firewall needed, your devices on your home LAN can't be accessed externally unless they specifically initiate the connection, and usually only the router is the only exposed device unless people explicitly choose to expose their private devices via NAT port forwarding or 1:1 forwarding.
With IPv6, hoo boy what a mess. The concept of NAT does not exist and is not implemented. Any IPv6 device can reach any other if it is not firewalled. This means you REALLY need to know how to set up a proper firewall with IPv6, because otherwise for tech novices, all your home devices could be exposed to hacking and snooping on the public Internet, and you wouldn't even know it.
Most nontechnical people simply will not have a clue here, so the problem of unintentionally exposed "private" devices is just going to accelerate as IPv6 gets implemented further and further.
