c. mathematics is simple and easy to use

d. information can be represented as numbers and manipulated mathematically

6. To create a digital signature, a sender needs the plain text, the
asymmetrical encryption algorithm, and ___________.

d. the receiver’s private key

7. One should establish access control policies for each part of the
information system that is ______________.

a. a high traffic area

b. a high security area

c. a high maintenance area

d. accessible to the public

8. If you are attempting to gain access to restricted information, what is the
first thing you should do?

a. kidnap an employee

b. ask for what purpose

c. spoof the server

d. disable the alarm system

9. Suppose your spy colleague wanted to send you messages that you could be
sure came from him (and not an enemy trying to pretend to be him). What CAIN
property is that? Your colleague tells you: “Whenever I send you a message,
the last thing in the message will be a number. That number will be a count of
the number of letter E’s in the message. If you get a message, and the number
at the end is NOT an accurate count of the number of letter E’s, that message
is from an imposter.” [a,b,c: 2 points, d: 4 points]

a) This number, put at the end of each message, is an example of what
cryptographic item?

b) Does it have the characteristic of being one wayi.e can you deduce the
original message by knowing the number?

c) Is it collision resistant?

d) Can you suggest some other way to indicate that message is from the sender
without resorting to encryption?

Chemistry

Suppose you are given 37.0 grams of salt water, and asked to find the % of
water and % of salt in the mixture. You pour the water into a 24.0 gram beaker
and boil off all the water, so only the salt remains. The beaker with salt in
it weighs 41.0 grams. What is the % of salt and % of water

Why is cryptology important in information security

Why is cryptology important in information security

Computer Network Security

Organizations use a wide variety of encryption technologies for various
purposes. A key aspect of security is using the correct and necessary levels
of encryption and hashing. The type of encryption and hashing needed varies by
the type of organization: government, military, healthcare, academic,
business, or financial. Address at least two of the following questions in
your response.

Why is cryptology important in information security?

What would be the implications of not using cryptographic technologies?

Why might vendors propose proprietary encryption methods? Why is this suspect?

What are the benefits of using encryption? What are the negatives or costs of
using encryption?

Explain common organizational security threats

Explain common organizational security threats

Computer Network Security

After reading your memo, your manager agrees that steps need to be taken to
get his team to think about security. He has asked you to help.
Create either a PowerPoint presentation, or a training manual, that will help
get the team to think about security. This training document should cover the
following key areas:
1. Explain common organizational security threats (avenues of attack).
2. Convince the team that a majority of security issues derive from personnel.
3. Explain the risks to the organization”s database environment.

How patients react when confronted with negative test result

Qualitative Research Designs

You have focused on the features and considerations of quantitative research
designs. However, quantitative designs are not appropriate for all research
questions. Perhaps you are concerned with how patients react when confronted
with negative test results, or you wish to study how views on a certain health
topic change over time. In each of these cases, the emphasis is more on
understanding the thinking and experiences of an individual or group than on
numerical measurements. For these types of questions, a qualitative or mixed
methods research design is the most appropriate.

For this Discussion, you focus on the different types of qualitative research
designs, when they are used, and why they are important.

To prepare:

Reflect on the comments made by Dr. Mauk in this week’s media presentation on
the value of qualitative research in nursing.

Locate the journal Qualitative Health Research in the Sage Premier database in
the Walden Library.

From this journal, select an article of interest to you that was published
within the last 3 years.

Review the information on different qualitative research designs in Chapter 20
of your course text.

Determine what qualitative research design was used in your selected article
and evaluate whether it was the best choice.

Consider ethical issues involved in the study and how the researchers
addressed them.

Think about how using a quantitative design would have affected the type of
data gathered.
