Hi EKR, I'll assume you're happy with the previous responses. These are all new comments and have been responded to and addressed.
I requested that the updated version be posted pending approval. Responses inline. On Wed, Mar 14, 2018 at 8:36 PM, Eric Rescorla <e...@rtfm.com> wrote: > I have reviewed the new version.

Perhaps "enterprises, whose networks are > often only made accessible for business purposes" You are typically subject to monitoring of all traffic from a company network by policy and a signed agreement at the time of employment (at least in the US). Many companies exclude financial site access as not to expose PII, but not social media and sharing platforms as that's an easy mechanism to exfiltrate data. These sites are still accessible, just monitored, so I wouldn't want to falsely change the text to say the network is only available for business purposes. I would personally advise people to follow that practice at work though. I made the following edits to consider the outbound access of a user in the description of data. The original text was focused on the corporate data and resources. "The implications for enterprises, who own the data on their networks or have explicit agreements that permit monitoring of user traffic is very different from service providers who may be accessing content that violates privacy considerations." > > only the headers exposed for the data-link, network, and transport > layers.

Sandvine-type DPI devices are > certainly intended for SPs. The text says, "Delving deeper is possible", so that covers your example. The text is from Chris Morrow who has quite a bit of operator experience into what actually happens in service provider networks. This text akcs that DPI is possible, but states that the more often used information from packet streams is limited to header information from link, network, and transport layers. A continued shift in this direction bodes well for end-to-end.

That's meant to mean these are the most common. It doesn't exclude anything with that wording IMO. This does align with my experience and what we've heard. The loudest complaint on HTTP was redirect abilities to let customers know why their access isn't allowed or for other notifications for non-SMS users. > > > A gap exists for vendors where built-in diagnostics and > serviceability is not adequate to provide detailed logging and > debugging capabilities that, when possible, can access cleartext > Nit: "are not" > Changed, thanks. > > > debugging capabilities that, when possible, can access cleartext > network parameters.
