Budget: $30 – $250 USD
THE FOLLOWING RESEARCH AND WRITING TASKS ARE FOR WORK PURPOSES AND SHOULD BE CONDUCTED IN A PROFESSIONAL MANNER. APA FORMAT CITATION IS A MUST.
Task 1:
Answer the following:
- Locate a recent article (from 2010 onwards) on database security on one of the registered websites, summarize and discuss the major issues raised.
* Cite any source in APA format.
Task 2:
Answer the following:
- Using web based sources discuss role based access controls (RBAC) and how they compare to other types of controls such as label based access controls (LBAC).
* Your answer must have a conclusion and title page. Cite any source in APA format.
Task 3:
Answer the following:
- Database systems are in use everywhere in our society. Discuss your personal experiences with an access control method and explain in detail how it worked.
* Your answer must be between 3-5 paragraphs long. Cite any source in APA format.
Task 4:
D-Latch is a simple clocked memory element in which the output is equal to the stored state inside the element.
In D-Latch the state is changed whenever the appropriate inputs change and the clock is asserted. A D-Latch has two inputs and two outputs.
The inputs are the data value to be stored and a clock signal that indicates when the latch should read the value on the data input and store it. The outputs are simply the value of the internal state and its complement.
When the clock input is asserted, the latch is said to be open, and the value of the output becomes the value of the data input. When the clock input is de-asserted, the latch is said to be closed, and the value of the output is whatever value was stored the last time the latch was open.
Answer the following questions:
- What is the difference between DFF and D-Latch?
- Can one chip be used for constructing the other? Explain.
* Cite any source in APA format.
