Maintain a Database Security (Inference Detection Algorithm)
Consider a database containing personnel information, including names, addresses, and salaries of employees. Individually, the name, address, and salary information is available to a subordinate role, such as Clerk, but the association of names and salaries is restricted to a superior role, such as Administrator.
1. With this information, how could you construct your database and tables? Design your database and draw a database schema first.
2. Suppose that administrators wants to add a new attribute, employee start date, which is not sensitive. Where would it be? Consider not comprimising the relationship between employee and salary. Draw your new schema
Answers
To construct a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries."
The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information.
Explanation:
To design a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries." The "Employees" table contains the name and employee ID of each employee. The "Addresses" table contains the employee ID and their corresponding address. The "Salaries" table contains the employee ID and their corresponding salary. The "Employees" table is accessible by both Clerks and Administrators, while the "Addresses" and "Salaries" tables are accessible only by Clerks and Administrators, respectively. The database schema for this design would consist of three tables with the employee ID serving as the primary key and foreign keys linking the tables.
The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information. This column would not compromise the relationship between employee and salary, as the salary information is still only accessible by Administrators through the "Salaries" table. The new database schema would include the "Employees" table with the added column for employee start date.

Answers
TLS does not require mutual authentication. The most common way for public key authentication would be a certificate.
A cryptographic technique called Transport Layer Security (TLS) is intended to guarantee communications security over a computer network. Although the protocol is widely used in voice over IP, email, and instant messaging, its use to secure HTTPS is still the most commonly known.
Through the use of cryptography, such as the usage of certificates, the TLS protocol primarily attempts to offer security, including privacy (confidentiality), integrity, and authenticity between two or more communicating computer programs. The TLS record and TLS handshake protocols make up its own two levels, which it runs in the application layer.
In 1999, the Internet Engineering Task Force (IETF) originally proposed the TLS standard. The most recent version, TLS 1.3, was established in August 2018.

Which cue will typically elicit the fastest reaction time to the target in the symbolic cuing task?A) InvalidB) NeutralC) ValidD) Colorful
Answers
The cue that typically elicits the fastest reaction time to the target in the symbolic cuing task is option C) Valid.
In the symbolic cuing task, participants are presented with a cue that indicates the location where the target stimulus will appear. The cue can be valid (correctly indicating the target location), invalid (incorrectly indicating the target location), neutral (providing no information about the target location), or colorful (having distinct color or visual features).
The valid cue provides accurate information about the target location, allowing participants to prepare and direct their attention to that specific location. This prior information results in faster reaction times as compared to invalid or neutral cues where attention needs to be redirected or gathered from scratch. The colorful cue may attract attention, but its impact on reaction time may vary depending on the specific task and individual factors.

I used the names George Clooney and Tim Allen to remember the pairs of nitrogenous bases in DNA.
Explanation:
DNA is composed of nucleotides, however the nucleotides are formed by nitrogenous bases called Adenine, Guanine, Cytosine and Thymine. Each nucleotide has a nitrogenous base, but these bases form pairs, allowing the nucleotides to come together. The pairs are formed solely by Timine and Adenine or Guanine and Cytosine.
As I needed to remember the formation of the pairs to do my biology test, I associated the first letter of each base, with the initials of two famous names.
As Guanina is paired with Cytosine (G-C), I associated this pair with the initial letters of the name George Clooney. As Timina is paired with Adenina (T-A), I associated this pair with the initials of the name Tim Allen.

The smallest defect in a computer chip will render the entire chip worthless. Therefore, tight quality control measures must be established to monitor these chips. In the past, the percent defective at Chieh Lee's Computer Chips has been 1.2%. The sample size is 1,200. Determine upper and lower control chart limits for these computer chips. Use z=33.
Upper Control Limit (UCLp) equals=______ (round your response to four decimal places).
Lower Control Limit (LCLp) equals=________ (round your response to four decimal places)
Answers
To determine the upper and lower control chart limits for the computer chips at Chieh Lee's Computer Chips, we need to calculate the values using the given information.
First, we need to find the standard deviation (σ) of the sampling distribution using the percent defective (p) and the sample size (n). The formula to calculate the standard deviation is:
\(σ = √(p(1-p)/n)\)
Given that the percent defective is 1.2% (or 0.012) and the sample size is 1,200, we can substitute these values into the formula to find the standard deviation.
\(σ = √(0.012(1-0.012)/1200)σ = √(0.01176/1200)σ = √0.0000098σ ≈ 0.00313\)
Next, we need to calculate the control chart limits using the standard deviation (σ) and the given value of z=3.3. The formulas to calculate the control chart limits are:
Upper Control Limit (UCLp) = 0.012 + (3.3 * 0.00313)
Lower Control Limit (LCLp) = 0.012 - (3.3 * 0.00313)

A blue screen is most often caused by____?A. Driver failureB. Memory failureC. Hard driver failureD. CD-ROM failure
Answers
A blue screen is most often caused by A. Driver failure.
A blue screen (also known as the "blue screen of death") is a stop error screen that appears when the operating system encounters a critical error from which it cannot recover. While there can be several possible causes for a blue screen, driver failure is one of the most common reasons for it.
Drivers are software programs that allow the operating system to communicate with hardware devices such as the graphics card, network adapter, or printer. If a driver is outdated, incompatible, or corrupted, it can cause system instability, crashes, and blue screens.
While memory failure (option B), hard drive failure (option C), and CD-ROM failure (option D) can also cause system issues, they are less likely to cause a blue screen. Memory failure can cause a system crash, but typically results in a different type of error message. Hard drive and CD-ROM failures can cause data loss or read/write errors, but are not typically associated with blue screens.
The correct option is A.

a server within your organization has suffered six hardware failures in the past year. it management personnel have valued the server at $4,000, and each failure resulted in a 10 percent loss. what is the ale?
Answers
The annualized loss expectancy (ALE) for a server that has suffered six hardware failures in the past year, resulting in a 10 percent loss each time and with a value of $4,000, can be calculated as follows:
ALE = (Number of failures) * (Loss per failure) * (Value of asset)
= 6 * (10/100) * $4,000
= $240
This means that the ALE for the server is $240 per year.
What is Annualized loss expectancy (ALE)?
The ALE is a measure of the expected loss or cost associated with an asset or risk over a given period of time, and can be used to help organizations make informed decisions about how to allocate resources and manage risks.
In this case, the high number of hardware failures and resulting losses suggest that the server may be unreliable and may require additional maintenance or replacement to reduce the risk of further failures and losses.
