Confidentiality, integrity, and availability or the CIA triad of security is introduced in this session.

Confidentiality, integrity, and availability or the CIA triad of security is introduced in this session. These three dimensions of security may often conflict. Confidentiality and integrity often limit availability. So, a system should provide only what is truly needed. This means that a security expert has to carefully analyze what is more important among these three dimensions of security in a system or application.
Please provide an example (and justification) where the confidentiality of a system is more important than the integrity or availability of that system. Then provide an example where the integrity of a system is more important than the confidentiality or availability of that system. Finally, provide an example of a system where the availability of a system is more important than the confidentiality or integrity of that system. For example, you might say availability is more important than integrity and confidentiality in a cell telephone system since one must be able to reach their loved ones in an emergency. Someone else might argue confidentiality/privacy is more important in such a system.

The Pacific Ocean is a powder keg ripe for explosion with the Imperial Red Fleet (IRF) making trouble by terrorizing the shipping lanes between us and our interests in the Far East.

Background: The Pacific Ocean is a powder keg ripe for explosion with the Imperial Red Fleet (IRF) making trouble by terrorizing the shipping lanes between us and our interests in the Far East. The Pacific Blue Fleet (PBF) needs a capable commander to lead them in this time of peril. You have been selected as the new commander of the United States Pacific Blue Fleet. Reconnaissance units have located the enemy fleet. You job is to engage the enemy fleet and annihilate them completely. The IRF fleet is well equipped and possesses ships that rival your own. They would like nothing more than to send your fleet to the bottom of the ocean. This battle would be decided by the cunning and tactics of the commander. Mode: The game should have three player modes: player vs. player or player vs. computer or computer vs. computer. Goal: Strategically place your ships throughout your part of the ocean to keep them away from the enemy. Try and sink the enemy by hitting their ships before they hit you! Skill Level: When the game is in player vs. computer mode, there should be 3 skills levels. The skill levels are as follows: Beginner: The computer randomly guesses selects coordinates. No intelligence involved. Intermediate: The computer will make an educated guess passed on previous hit. For instance, if computer achieved hit, it should check next available coordinate along x coordinate. Expert: The computer will make an educated guess passed on previous hit. For instance, if computer achieved hit, it should check next available coordinate along x axis and/or y axis. Ocean Grids: The Pacific Ocean is broken up into two ocean grids: one grid for each fleet. An ocean grid consists of a 10 x 10 grid. Each position on the grid will be represented by a two positive integers that constitutes a XY coordinate. Ships: There are a total of 5 ships for both the PBF and the IRF respectively. Each fleet has the same complement of ships. The description of the ships is listed below including the number of hits needed to sink a ship:  Aircraft Carrier 5 hits  Battleship – 4 hits  Cruiser – 3 Hits  Destroyer 3 hits  Submarine – 2 Hits Deployment: Each ship will be strategically placed in their part of the ocean. Ships must be placed horizontally or vertically. It cannot be diagonal. Basically, for each ship placement, either the x or y coordinate must be the same for every coordinate of that particular ship. For example, a cruiser could be: (8,1) (8,2) (8,3) or a battleship could be: (5,3) (6,3) (7,3) (8,3) How to Begin: When the game begins, the program should prompt the PBF player to enter the coordinates of every ship in the PBF fleet one at a time. Once all of your ships have been entered, the IRF player will enter the coordinates for all of the ships of their fleet. Game Rules: The PBF player will fire first by entering a XY coordinate. If the entered coordinate scores a hit (i.e. the entered coordinate corresponds to a position on the ocean grid occupied by an enemy ship) the program should indicate that an enemy ship was hit. The PDF player would be allowed to enter in another coordinate. Once the PBF player one misses (selecting a coordinate that is not occupied by an enemy ship), player 2 would be asked to enter a coordinate. Once a player sinks a ship, the program should indicate that ship was sunk and specify which ship was sunk. Note: The program should not indicate the type of ship when it is first hit. It should only be specified once the ship is sunk. The first player that sinks all of the enemy ships will win the game. Error Checking: The game should have some basic error checking functionality built-in. The following functionality should be included: The game should check to make sure that multiple ships are not placed on the same coordinates. When deploying a ship, the game should insure that the players place acceptable coordinates for each ship. For example, if a ship has a 1st coordinate of (2,1), it should not accept (3,4) as a second coordinate because they are not continuous. The game should make sure that when a player fires on a ship, they don’t select a coordinate outside of the grid. The game should make sure no ship is placed on a coordinate outside of the grid. The game should not allow a player to fire at the same coordinate more than once during a game. Bonus Points: For those individuals interested in an additional challenge, here are some ideas for enhancements: The game requires that the program prints a response indicating when a ship is hit. Modify the program so that it randomly responds with different messages when a ship is hit. For example: “Great shot” “Hit her again!” “Go for the kill!” If you have other ideas for bonus points, they may be submitted for consideration What to turn in: You need to turn in the following: Software requirements specification outlining what you program will do, any assumptions, class / function diagram and “will-do” list Complete printed out source code including any user created header files: Sample output for various runs to illustrate the game in action Submit a soft copy of all source and executable files. Instructions for playing the game Sample Run: PBF player enter ship coordinates: Carrier 1st coordinate: 1 2 Carrier 2nd coordinate: 1 3 Carrier 3rd coordinate: 1 4 Carrier 4th coordinate: 1 5 Carrier 5th coordinate: 1 6 Your carrier has been deployed! Battleship 1st coordinate: 5 6 Battleship 2nd coordinate: 4 6 Battleship 3rd coordinate: 3 6 Battleship 4th coordinate: 2 6 Your battleship has been deployed! …… And so on for the rest of the PBF ships …. IRF player enter ship coordinates: Carrier 1st coordinate: 4 9 Carrier 2nd coordinate: 5 9 Carrier 3rd coordinate: 6 9 Carrier 4th coordinate: 7 9 Carrier 5th coordinate: 8 9 Your carrier has been deployed! Battleship 1st coordinate: 8 3 Battleship 2nd coordinate: 8 4 Battleship 3rd coordinate: 8 5 Battleship 4th coordinate: 8 6 Your battleship has been deployed! …… And so on for the rest of the IRF ships …. Start the battle! PBF fire at a coordinate: 5 5 You missed! IRF fire at a coordinate: 2 6 Direct hit! IRF fire at a coordinate: 3 6 Direct hit! IRF fire at a coordinate: 4 6 Direct hit! IRF fire at a coordinate: 5 6 Direct hit! You sank the PBF battleship! IRF fire at a coordinate: 1 1 You missed! PBF fire at a coordinate: 8 6 Direct Hit! …. PDF, you win! Great game! IRF, you are demoted! Return home in shame! Would you like to play again? (Y/N)

22. Imagine you are the database administrator for a military transportation system. There is a table named cargo in the database that contains information on the various cargo holds available on each outbound airplane. Each row in the table represents a single shipment and lists the contents of that shipment and the flight identification number. Only one shipment per hold is allowed. The flight identification number may be cross-referenced with other tables to determine the origin, destination, flight time, and similar data. The cargo table appears as follows: Flight ID Cargo Hold Contents Classification 1254 A Boots Unclassified 1254 B Guns Unclassified 1254 C Atomic Bomb Top Secret 1254 D Butter Unclassified
There are two roles defined: Role 1 has full access rights to the cargo table. Role 2 has full access rights only to rows of the table in which the Classification field has the value Unclassified. Describe a scenario in which a user assigned to Role 2 uses one or more queries to determine there is a classified shipment on board the aircraft.
23. As part of a formal risk assessment on the use of laptops by employees of a large government department, you have identified the asset “confidentiality of personnel information in a copy of a database stored unencrypted on the laptop” and the threat “theft of personal information, and its subsequent use in identity theft caused by the theft of the laptop.” Suggest reasonable values for the items in the risk register for this asset and threat, and provide justifications for your choices.
24. Consider a popular Digital Rights Management (DRM) system like Apple’s FairPlay, which is used to protect audio tracks purchased from the iTunes music store. If a person purchases a track from the iTunes store by an artist managed by a record company such as EMI, identify which company or person fulfils each of the DRM component roles (Content Provider, Clearinghouse, Consumer, and Distributor).
25. Assume you receive an e-mail which appears to come from your bank, includes your bank logo on it, and with the following contents:
“Dear Customer, Our records show that your Internet banking access has been blocked due to too many login attempts with invalid information such as incorrect access number, password, or security number. We urge you to restore your account access immediately, and avoid permanent closure of your account, by clicking on this link to restore your account. Thank you from your customer service team.” What form of attack is this e-mail attempting? What is the most likely mechanism used to distribute this e-mail? How should you respond to such e-mails?
