During week 2 of the FBI Citizens Academy we were introduced to the cybercrime division and the art of the polygraph.
The FBI's cyber crime mission is to:
1. Stop serious computer crime intrusions
2. Identity and thwart online sexual predators using the Internet for crimes against children
3. Counteract operations that target US intellectual property, endangering national security and competitiveness
4. Dismantle national and transitional organized criminal enterprises engaged in Internet fraud.
Terrorists use the Internet to facilitate the "3 C's" - Command, Control, and Communication. The FBI reports that terrorists commonly use public sites for intelligence gathering, like Google maps and localized municipalities that put maps of critical infrastructure on their websites. In addition, terrorists use the Internet for advertising, propaganda, fund raising, recruitment and training.
Often times, the terrorist groups use US based businesses (Yahoo, MSN, Gmail) for email because US privacy laws protect the information. At any one time, there are an estimated 5 to 20 thousand active terrorist websites on the Internet. A number of prior terrorist website examples were shown including discussion boards that were being used to share intelligence on target victim sites. The FBI called out a number of common cyber security attacks that included: website defacement, denial of service, Intrusion and SCADA. In particular, the threats and possible outcomes with regards to importance of SCADA systems were highlighted.
The second primary discussion point for cyber security was that of crimes against children. Due to the long-term psychological impact related to these types of cases, agents must volunteer for these assignments. The presenter discussed their common workloads and walked the class thru two case studies that involved pedophile activity discovered when the perpetrator posted evidence online. What I found most interesting about this part of the presentation was the role the Internet has played in finding these perpetrators. Crimes against children are not new and if law enforcement primarily finds suspects due to Internet activity, then consider the number of people who don't put their pictures on the Internet. And how many of these crimes are / were committed before the Internet came into existence.
The second topic for week 2 was the polygraph. Polygraph, means "many tracings", and the test examines the subject's physiological reactions to questions by looking for changes in breathe rate, sweat and cardio.
The polygraph test itself consists of three phases; the pre test interview, the in-test phase and the post-test. The polygrapher reviews the results and determines the results to be one of three classifications: NDI, DI or INC. These acronyms stand for No Deception Indicated, Deception Indicated and Inconclusive. The results of polygraph tests are not admissible as evidence due to a number of precedent setting court cases. In addition, in a number of independent studies including a 2003 report from the National Academy of Sciences, find the tests to be less than 100% accurate.
Within the FBI there are 95 examiners nationwide and nearly 18,000 exams are issued each year worldwide. In order to qualify as a polygrapher, agents must pass a 14-week course administered by the Academy of Polygraph Science. The training includes administering 50 live exams during the 14 weeks. Upon graduation, agents are assigned to a senior examiner for 1 year.
