5. d) The transmit power of a satellite is 20 W. The gain of the transmit antenna is 30dB while the gain of the receive antenna is 20dB. Distance from the satellite to the ground receiver antenna is approximately 1000 km. The operating frequency is 9 GHz.  Recalling the following “Friis” relationship governing received  and transmitted power between 2 antennas separated by a distance R (Hint: you don’t want to use dB or dBm values for any quantities in this equation. )  Choose from the following options the one that best fits the power level in dBm received at  the output of the ground antenna

In an essay of no less than 250 words, answer the following:   According to the National Institute of Standards and Technology Special Publication (NIST SP) 800-100, “risk is a function of the likelihood of a given threat source’s exercising a particular potential vulnerability, and the resulting impact of that adverse event on the organization.” Therefore, risk is an equation that includes likelihood, threats, vulnerabilities, and impacts. Define an example information system and describe the risk assessment process and the resulting risk calculation as applied to that hypothetical information system. Be sure to include the categorization/characterization of your hypothetical information system as part of your calculation.    Be sure to cite your sources if paraphrasing or quoting others, and expand all acronyms for clarity. Do not use sources from outside this course’s materials, as this will lead to a score of 0 points for this essay.
