Short Answer

1. Describe a historical period in which humans used and managed knowledge before the use of computers.
   1. Answers will vary but can include examples from the text. The emergence and evolution of libraries and methods to store books and manuscripts systematically represent such early efforts. Early big data played a key role in the Allied Powers gaining strategic advantage over the Axis Powers during World War II.
2. Define the concept of risk management.
   1. Risk management is the process for identifying, analyzing, and communicating risk and accepting, avoiding, transferring, or controlling it to an acceptable level considering associated costs and benefits of any actions taken.
3. Explain why information sharing was problematic in the pre-9/11 era.
   1. Agencies were reluctant to share information with each other, and, when they did, information sharing occurred in limited, non-systematic manner, almost always based on personnel relationships. An investigator from one agency might call a friend in another to pass along a name or phone number; in a robust instance of sharing, the agent might send over the whole case file.
4. Which agencies are provided with information available in the Terrorist Screening Database (TSDB)?
   1. Six major federal data users receive TSDB information: TSA’s Secure Flight; CBP’s TECS system; the Department of State’s Consular Lookout and Support System (CLASS) for passport and visa screening; the Transportation Vetting System for credentialing transportation and critical infrastructure workers; the Department of Defense; and the FBI’s National Crime Information Center’s Known or Suspected Terrorist File for domestic law enforcement
5. Identify some potential flaws in the Secure Flight program.
   1. In addition to air passenger vetting, for example, TSA is also responsible for vetting aviation workers for terrorism links. A DHS Inspector General analysis in 2015 found that TSA had failed to identify 73 individuals with links to terrorism. As a result, the 73 individuals “were cleared for access to secure airport areas despite representing a potential transportation security threat. The error occurred because the individuals were excluded from the terrorism watchlist that TSA received.
