Addendum Re: The legal basis for Service monitoring Title 18 Section 2511.2.a.i Re: Why TOR Operators SHOULD always sniff their exit traffic...



In addition I came across these, as I quite often have acted under color of law when investigating computer intrusions/assisting law enforcement investigations. these are also very interesting

TITLE 18--CRIMES AND CRIMINAL PROCEDURE

                           PART I--CRIMES

CHAPTER 119--WIRE AND ELECTRONIC COMMUNICATIONS INTERCEPTION AND INTERCEPTION OF ORAL COMMUNICATIONS

Sec. 2511. Interception and disclosure of wire, oral, or electronic communications prohibited

  (2)(i)

and 3a


(i) It shall not be unlawful under this chapter for a person acting under color of law to intercept the wire or electronic communications of a computer trespasser transmitted to, through, or from the protected computer, if--
(I) the owner or operator of the protected computer authorizes the interception of the computer trespasser's communications on the protected computer;
(II) the person acting under color of law is lawfully engaged in an investigation;
(III) the person acting under color of law has reasonable grounds to believe that the contents of the computer trespasser's communications will be relevant to the investigation; and
(IV) such interception does not acquire communications other than those transmitted to or from the computer trespasser.


(3)(a) Except as provided in paragraph (b) of this subsection, a person or entity providing an electronic communication service to the public shall not intentionally divulge the contents of any communication (other than one to such person or entity, or an agent thereof) while in transmission on that service to any person or entity other than an addressee or intended recipient of such communication or an agent of such addressee or intended recipient.
(b) A person or entity providing electronic communication service to the public may divulge the contents of any such communication--
(i) as otherwise authorized in section 2511(2)(a) or 2517 of this title;
(ii) with the lawful consent of the originator or any addressee or intended recipient of such communication;
(iii) to a person employed or authorized, or whose facilities are used, to forward such communication to its destination; or
(iv) which were inadvertently obtained by the service provider and which appear to pertain to the commission of a crime, if such divulgence is made to a law enforcement agency.



note item iv


again comment is invited from REAL EFF Lawyers as we are talking about the ECPA now and this is actually what the text of the law says.

Hi All,


BTW Chris... you may wish to examine with your EFF Attorney the following section of USC Code Title 18


http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=browse_usc&docid=Cite:+18USC2511


to wit:

TITLE 18--CRIMES AND CRIMINAL PROCEDURE

                            PART I--CRIMES

CHAPTER 119--WIRE AND ELECTRONIC COMMUNICATIONS INTERCEPTION AND INTERCEPTION OF ORAL COMMUNICATIONS

Sec. 2511. Interception and disclosure of wire, oral, or electronic communications prohibited

(2)(a)(i) It shall not be unlawful under this chapter for an operator of a switchboard, or an officer, employee, or agent of a provider of wire or electronic communication service, whose facilities are used in the transmission of a wire or electronic communication, to intercept, disclose, or use that communication in the normal course of his employment while engaged in any activity which is a necessary incident to the rendition of his service or to the protection of the rights or property of the provider of that service, except that a provider of wire communication service to the public shall not utilize service observing or random monitoring except for mechanical or service quality control checks.

Note the phrase "to the protection of the rights or property of the provider of that service".
Note the prohibition of service observing/Random Monitoring applies to wire communication services only
(IE telephone companies). If current case law contradicts this please feel free to inform us all via the with specific cases etc...


please chris have the EFF lawyers comment on this aspect of ECPA. I am sure all us on the list would indeed be fascinated.

I understand the need, and I'll fly it past our lawyers to see what they think about drafting such a policy paper. They are unlikely to make strong, specific, forward-looking legal statements, of course.

I can tell you what I do, which I regard as reasonably safe and polite.

I run three Tor servers: one at EFF (confidence), one on a machine some
friends and I share (explosivenoodle), and one on my home DSL line
(livingcolour). confidence and explosivenoodle I run in middleman mode,
to minimize annoyance and potential liability for my employer and
friends (respectively). (EFF is considering running an exit server, but
we aren't yet.) livingcolour uses the default exit policy. All three
servers are rate-limited to about 20Kb/s because bandwidth is either
donated and I want to be nice (explosivenoodle), or limited (confidence
and livingcolour). I don't sniff traffic on any of these three hosts,
and I log at warn level, using debug level only for limited times when I
actually am trying to debug something (rarely). All three machines are
kept up-to-date and run only services I actually use.

I don't commit abuse through Tor when I use it. That's easy -- "Oops, I
didn't troll on IRC again!"

I sometimes drive around in the Tor source tree for fun and learning,
but I haven't found any security bugs. If I did, I would simply tell
Roger and Nick. I have reported a few security-irrelevant bugs (and, I
sheepishly admit, non-bugs) to R and N and they have fixed them fast.
There was once a problem with bad interaction between two configuration
directives, for example, which caused Tor not to start. Nick fixed it in
minutes.

Hence, for basic operation and examination, the existing norms of the
competent sys admin and white hat security researcher communities apply.

As for passing "bad" traffic, so far I haven't heard from my ISP about
any problems with my exit node. Maybe I'm just lucky. There are various
types of complaints, and different responses are called for in different
circumstances. Get legal counsel, possibly the EFF. See also the Legal
FAQ and our DMCA response template
(http://tor.eff.org/eff/tor-dmca-response.html). Everyone has different
responses to complaints, resulting from the specifics of their
situation, their beliefs and temperaments, the nature of the complaint,
their relationship with the complainant and with their connectivity
provider, various jursidictional issues, and so on. It's hard to make
any general a priori statements about what to do, other than "Call
EFF!". That's obviously what I would do. :)

I don't know if that helps you or answers your question. I'll state
again that the non-dangerous techniques I mentioned in my previous email
have proven helpful in finding bugs in other software products. Roger
and Nick welcome substantive bug reports, and they take security very
seriously.
