IT Security Audit Results

• ESDIS Security Audit (Oct., 02)
• NSIDC received excellent score
• Vulnerability rating of 0.06
• 0.25 is acceptable the lower the score, the
  better
• Only 1 DAAC received score better than NSIDCs
• Vulnerability ratio high vulnerability
• Total of
  systems
• NSIDC 4
• 70

20
IT Security Improvements After Audit

• Audit performed in Oct. 2001
• By Jan. 8, 2 of 4 vulnerabilities eradicated
• Now, vulnerability rating is 2/70 0.03
• Working to address remaining 2 vulnerabilities

IT Security

• Excerpts from audit, by Titan Systems Corp.
• I also want to compliment you on your scanning
  procedure that you have implemented, such efforts
  makes sic our job easier and allows us to focus
  our time on sites that need it.
• You are setting a great example for other DAACs
  to follow and proves sic that a DAAC can
  operate in a secure fashion.
• Ronald W. McClellan, Principal INFOSEC Engineer

• All relevant systems have TCPwrappers installed
• Tripwire installed
• SSH Secure Shell in use in lieu of telnet
• Install patches to OS and other COTS packages, as
  needed
• Support ESDIS audits every 6 months

Comprehensive Documenation Status

• NSIDC ECS I-SIPS ICD Baselined in Dec. 01
   
• NSIDC ECS I-SIPS Volume 0 Baselined Dec. 23,
  98 (Revision E released Nov. 14, 01.)
•  
• NSIDC Operations Agreement NSIDC-ISIPS
  Completed. Hancock et al. will sign when Marquis
  is at GSFC for MOWG Jan. 30, 02
•  
• NSIDC Operations Agreement NSIDC-EDOS I've
  asked Bob Lutz to confirm that a separate OA
  between NSIDC and EDOS for ICESat/GLAS data is
  not needed. He has agreed, but wants to confirm
  this with someone else. Such an additional OA
  seems unnecessary, in light of the appendix in
  the EGS-EDOS ICD. Also, there is an OA between
  EDOS and the ECS SDPS (510-OA-EDOS/SDPS).
• NSIDC Operations Procedures Document Most of
  the components are complete now. Others will be
  complete by Feb. 15. All procedures will be
  documented on an internal NSIDC ECS web site by
  June. A PowerPoint Slide that we used for the
  Aqua Interim ORR Jan. 9 gives more details.
• NSIDC Data Set Guide Documents The altimetry
  guide document was drafted and reviewed by
  Hancock and Brenner in May, 01 and July 01,
  respectively. The atmospheric products guide
  document has been drafted by not yet reviewed by
  GLAS scientists. Both of these guide documents
  will be further edited and sent to GLAS
  scientists for another review by Feb. 28, 02.
  David Hancock is still changing some of the
  product parameters, and we will need these nailed
  down no later than Aug. 15. In-house (NSIDC)
  review of altimetry and atmospheric guide
  documents will begin Aug. 1 and end Sept. 30.
  GLAS scientists final review will be Oct. 1-15.
  The GLA16 product (the composite product in
  HDF-EOS format) is not yet defined. Once defined,
  well draft guide document and have it reviewed
  by GLAS scientists.
•  
• NSIDC Data Interchange Format Documents These
  were drafted and reviewed by Hancock Feb. 01.
  Final in-house review of these 17 DIFs (after
  Hancock nails down final parameters) will be Aug.
  1-Sept. 30, and final review by GLAS scientists
  Oct. 1-15.
