I have contacted NASA on several occasions so they could take the necessary countermeasures to safeguard and harden their systems. Unfortunately I never received a response. Below is the most recent exploit of the leakage of content. One can only hope that these entities keep their real critical data on a centralized system, disparate from distributed networks as a matter of national security. The question is how is it that these agencies are unable to perform the proper pentesting to check for vulnerabilities as well as do appropriate vulnerability assessment, risk management, network intrusion detection and network response?

--------------------------------------
IERS/CB DISTRIBUTION
The Central bureau of IERS (IERS/CB) [the International Earth Rotation
Service -- R.B.L.] is now connected to ANONYMOUS FTP through Internet.
This account can be used by all users of IERS/CB publications .
Access to the files :
====================
ftp 130.84.200.6
with login : anonymous
and password :name/organization/country
The password is intended to help us for further statistics.
After loggin on, the user should change to the appropriate directory with the
command "cd /iers" and use the command "get" to transfer the wanted files.
The "ls" command gives the list of files.
Description of the files :

PROCESSING STRATEGY:
-------------------------------------------------------------------------------
- The analysis was done by fixing the GPS orbits and Earth rotation parameters
to the CODE final GPS solution.
- The orbital parameters for the GLONASS satellites were estimated using double
difference phase observations (including double differences between GLONASS
and GPS satellites). Six initial conditions and nine radiation pressure para-
meters per satellite were determined. No pseudo-stochastic pulses have been
introduced up to now.
- So far only receivers providing dual frequency GPS and GLONASS or dual fre-
quency GLONASS measurements were included in the solution.
- The daily orbit results stem from the middle day of a 5-day arc.
- The satellite clock values included in the precise orbit files are broadcast
clock values for the GLONASS satellites (no improvement done so far) and
precise CODE estimates for the GPS satellites.
- At present only the site ZIMZ (Zimmerwald, Switzerland) was constrained to
its ITRF96 coordinates.

----------------
The router boxes on the connection between NSF net and australia,
specifically AARNET and all .au addresses were changed late last week in
the US. These boxes and their protocols are in compatable (sort of) with
the boxes in Australia. Replacement boxes have been sent from canberra
to Melbourne for munari which is our national gateway.
The effect is most noticable for traffic originating from Australia. The
sympton is a very heavily loaded communications link. Approaching
saturation, actually is saturated. Packets are being regenerated by the
hosts and retransmitted clogging the line. In excess of 40% of packets
are suffering this fate. For the end-to-end users they see thruputs of
0.2 kilobytes per second. Ftp doesnt time out, it working flat out!.
I noticed the problem over the weekend and our local folk initially
thought that it was just super heavy use until I produced logs of our
"normal" expectations.
This has implications for our work. It is important to keep logs of
thruputs that will aid tracing faults. It also indicates that we all
need to be aware of the expected rates and changes to these rates.

Subject: DATA flow start 15 JUNE
-----------------------
Dear Ericos
Thankyou for your note on the data flow.
I am feeling much better at the moment. The intense pain has subsided
and my general well being is improving rapidly.
I agree with you on starting the data flow as early as possible.
As you state Carey is due back this week. I will be trying to call early
today. I spoke to John Bosworth on Friday and he acknowledges the
importance of getting this to the top of Carey's priority list.
There are two items that need to be straightened out for data flow.
1. What is the EXACT path of entry of the following stations into A
NETWORK DATA CENTER. At the moment this is SIO/SCRIPPS, CDDIS and
STATENS KARTENS.
CANBERRA (TIDBINBILLA) JPL
Yaragadee JPL
Madrid JPL
Goldstone JPL
Tahiti
Hartebeestoeck
Santiago JPL
Usuda JPL
Fairbanks JPL
McMurdo JPL
Pinon Flat SIO
Los Palmas
Matera
Kootwijk
Ny Alesun
Tromso
Onsala
Metsahovi
Wettzell
Herstmonceux
Hobart
Wellington
Townsville
Koke Park
Yellowknife
Penticton
Algonquin
Richmond
Fortaleza
Taipei (Taiwan/Tai Shi)
Port Harcourt
Tsukuba
Orroral
This list reflects the Circular 2 list although we dont expect all sites
to be equipped with precision P-code receivers. At this point in time,
knowing that our data network can handle the load I am reluctant not to
collect this full set leaving the analysis centers freedom to choose.
I point out that Orroral is now an Ashtec dual P-code. I will initiate
discussions to see if this is indeed the only place that it can be run
for the campaign. From a geometry point of view Cocos Is is the best
location. We OZ folk will run that site for Epoch'92 but cannot afford
operational costs for the main campaign. I presume that Darwin would be
acceptable for many folk.
I think that the correct way to fill out the above is for Carey, in
Miranda's absence to fill in what she got from NGS. I presume that
Tahati and Hartebeestoeck will come from JPL. I would appreciate IGN
explicitly stating that this is the start-up path.
2 Compression routines. I think that the easiest way is for Carey to
send all of us a copy of a file that she has compressed. We should all
be able to say that we can read it. As I understand things now she got
her routines from Werner. Werner, SIO, Myself and JPL can all transfer
files without problems. Its just a case of getting the switches right. I
dont think that we should interfer with Carey and Dave Starr doing
uncompressed transfers since their bandwidth allows this. However I
think that our problems of congestion will be lower if we do adopt this
strategy and do it as close to the siurce as possible.
I will call Carey tonight about 11pm local time here. That is 1300UT.
The University of Canberra, in conjunction with the regional data center
at AUSLIG will collect a complete copy of CORE data and maintain a
complete copy of ALL regional data. This will reduce the load on the
PACIFIC link. This has recently been upgraded to 512 kbits per second.
In this upgrade there was the express desire to limit FTP traffic as
much as possible. AARNET has placed a small file server on the AARNET to
reduce multiple US accesses. We are being encouraged to do the same. For
IGS this is similar to our desire to have a network data center in
Europe.
Finally there is a lot of development going on on the network about
mailers. Thankyou for your comments on the LISTSERVER approach which is
used by UNB for their space forum. I hope that I can sumarize some of
this shortly.

Subject: IGN network data center
-----------------------
Here is the current status of the data center at IGN.
First of all, we expect to get our connection to the Internet for the 15th
of june. As soon as this connection is available, I intend to do some data
transfer tests with some european centers (CNES, IFAG, SK an CODE) and with
the american network data centers: CDDIS and SIO.
The data rate of the connection is 64 Kbps, this is the first parameter I want
to check, then I also need to verify the procedures we have developped to
manage the data flow in a fully automatic way.
At IGN, during the IGS campaign, we will first GET the data from IFAG and
CNES, then GET the complementary data of the core network from CDDIS and SIO.
I don't know if CODE intends wetherto receive the data from IGN or to get it
from IGN, can Werner GURTNER answer this question ?
The on-line storage capacity is 1 GB, so depending on the data compression rate
we should be able to keep between 40 and 80 days on-line. We will archive the
data on optical disks and DAT. The operating system is VMS. The data is stored
in DAY/STATION directories, the root being IGS$DATA:[CORE]. We will provide
access to the data by FTP under userid IGS and password REPUBLIQUE. The IP
address will be 192.33.147.225.
To summarize the status of IGN, we are ready to operate as soon as we are
connected to the Internet. I think that one week is a very short delay to
get fully operational on the IGS network, and that will be the maximum
delay for us considering the date of the 15 june for the connection. So we
might have to consider a temporary configuration without IGN as network
data center. In any case this should not last more than 15 days after the
beginning of the campaign. I will send more information on this to the mail
box next week. Can George PREISS from SK confirm their ability to operate
as a network data center during this period ?
My last point is that I need more information about the other IGS centers
(for some of them I don't have any), particularly those with wich we will
operate directly. I've heard of a directory of all the centers
participating to the IGS campaign but I don't know if it is achieved.
Anyway, this would be a very useful document for all of us. Can CDDIS, SIO
and CNES mail me their IP address, FTP account, computer directory names.
Do they provide access to the data 24 hours a day ?
Regards
Loic Daniel

NOTES:
(a) Those sites without a DOMES point number are at unknown locations,
and those sites with a (?) in the Alternate descriptions possibly have
an incorrect DOMES number.
(b) The epoch refers to the epoch at which the site position applies
and not the mid-point of the data span. We have also added the
velocities adopted for these sites at the end of each line.
(b) These coordinates were estimated from 152 GPS experiments spanning
the interval from January 1991 to May 1992. There were 3,398,512 double
difference observations in the solution. All site positions were
estimated and the velocities were constrained to NUVEL-1 North American
fixed (NAFD) velocities. To align this solution with ITRF-90, we
propagated the ITRF-90 site coordinates from their 1988.0 reference
epoch to the epoch of the coordinates in our solution (1992.352) using
NUVEL-1 velocities (NAFD). A six parameter transformation was then made
between these coordinates and ITRF-90 after applying (most) of the ties
in IERS TN-10 using only the horizontal coordinates of 11 sites with
good ties and located outside of plate boundary zones (ALGO, YELL, DRAO,
FAIR, KOKR, DS40, TAS1, TROM, WTZ1, WETB, ONSA). The RMS difference of
the fit after the 6 parameter transformation was 20 mm. The rotated and
translated coordinates were then transformed to a AM0-2 frame by
applying the AM0-2 velocity of the North American plate maintaining the
orientation the systems at 1988.0

XXXX : The first day of the 2-day arc is used for ephemeris
dissemination
---- : The second day is used for quality control by overlap
The pole coordinates are estimated for three epochs (beginning
of each day) with the 2-day arc's. Using the above described
method (one day overlaps) there are three solutions for each
pole parameter. The submitted ERP-results are the mean values
of these different solutions.
- GFZ06507.EPH (Seven 1-day segments)
In the table below the overlap rms differences [m] in radial,
cross- and along-track component are presented.
