Re: NAT
I havent spoken or commented about data security, what i mean to say here is about Network Security. My previous comment share glimpse of only network and not data security. If i am not mistaken NAT can be considered as similar to encryption ..

Re: NAT
@Aditshar1 - Can you give the community an example of how you believe NAT can provide data security in an enterprise IT scenario? Thanks!

Re: NAT
I see your point @Andrew, but considering the fact that we modify network address information in IP datagram packet headers while they are in transit across a traffic routing device, some where or other we can say they do provide security.

Re: NAT
Hi Marcia,

Good point and question. It probably would not have occurred to me to raise the issue of security implications, so I'm glad you did. I did a little more digging. Here's what Andrew may be referring to when he said "it "hides" the true IP address structure from the outside world." https://www.grc.com/nat/nat.htm. I consider Gibson Research a solid source for such matters.

Re: NAT
I see, thanks Andrew. This blog also talks about how NAT can actually impede security.

Re: NAT
Hi Marcia - Some people think that NAT provides a layer of security because it "hides" the true IP address structure from the outside world. But in reality, it all depends on what ports you have open to the world. Whether they are NAT'd or not adds nothing from a security perspective.

Thanks for this guide Andrew. Can you elaborate on your point about the misconception of NAT providing security benefits?
