“ALL” operator: The operator “ALL” is used with “WHERE” or “HAVING” clause. If “ALL” operator is used in a subquery, then the condition returns true only if it satisfies all the values produced by the subquery. Syntax: SELECT column_Name(s) FROM table_Name WHERE column_Name ALL (SELECT column_Name FROM table_Name WHERE condition);

3. Problem Description: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. • A data field radius with a get method. • A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. • A constructor that creates a circle with the specified x, y, and radius. • A method getArea() that returns the area of the circle. • A method getPerimeter() that returns the perimeter of the circle. • • • A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b). A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. р O со (a) (b) (c)< Figure (a) A point is inside the circle.

1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.

Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.
