Letter to the Editor: Getting the Most from Metadata

SUMMARY

The Implementation Lead from the Signals Intelligence Directorate Metadata Strategy team offers an alternate response to a fictional analyst who asked about what intelligence can be easily extracted when you're swamped with metadata, in the Ask Raul column. While "quick and easy payoffs vary" depending on a number of factors, "they certainly include target discovery through contact chaining (both DNR and DNI); content prioritization via sophisticated algorithms and keyword searches; technology discovery; and target identity refinement."

DYNAMIC PAGE -- HIGHEST POSSIBLE CLASSIFICATION IS TOP SECRET // SI / TK // REL TO USA AUS CAN GBR NZL (U) Letter to the Editor : Getting the Most from Metadata FROM: SIGINT Communications Unknown Run Date: 05/11/2005 (U) We received the following comment on the recent article Ask Raul: Getting the Most from Metadata : From : ) Comment : Dear , (U//FOUO) Your question can be interpreted in a number of ways, and Raul has interpreted it in one fashion. I'd like to take a few other angles that may provide you and other analysts across SID with a better understanding of the many moving pieces in the world of metadata these days. There's a lot to cover, so I'll recommend that you consider looking at the website for the SID COMINT Metadata Strategy by visiting "go metadata" on your browser. You can also contact the SID Strategy team via the alias "DL METADATA" @nsa) if you have further questions or concerns, or need to know who to talk to for some specific issues. (S//SI) What can you do with your metadata? Well, it depends what kind of metadata it is you are referring to and what your analytic goal is. You say you are overloaded with it, so I'll assume you must be accessing metadata records through one of the corporate systems such as MAINWAY, FASCIA, BANYAN, or the UIS Metadata Viewer. Each of these provides a different angle into the metadata extracted from SIGINT, and efforts are underway both to ensure a single, unified access to these various sources (a project called GLOBALVISION), and to automate the rote elements of analysis. (S//SI) Quick and easy payoffs vary depending on the target set, analytic goal, and actual collection. Having said that, they certainly include target discovery through contact chaining (both DNR and DNI); content prioritization via sophisticated algorithms and keyword searches; technology discovery; and target identity refinement. Other uses of metadata available today include the analysis of target selectors in CADANCE to determine their effectiveness, as well as the more surgical tasking of active operations. (U//FOUO) Without further understanding of your particular circumstances, it is difficult to give a tailored answer. I'd suggest you contact me, and the SID Metadata Strategy team, to get more help. Thank you, Implementation Lead, SID Metadata Strategy "(U//FOUO) SIDtoday articles may not be republished or reposted outside NSANet without the consent of S0121 (DL sid_comms)."
