What are three different types of SIEM's on the market today? Security information and event management (SIEM) is a subsection within the field of computer security, where software products and services combine security information management (SIM) and security event management (SEM). They provide real-time analysis of security alerts generated by applications and network hardware.

A random variable (RV), x is distributed with a pdf as follows:

f_X(x) = [C × x × (1 – x)]       0 ≤ x ≤ a            (C and a are constants)

         = 0                                otherwise

Hence, determine the following: (i) C; (ii) cumulative probability of x in the range, [(u × a) ≤ x ≤ (v × a)]; where u and v are fractions; (iii) E[x]; (iv) second moment of x ; and, (v) standard deviation of x. Assume: a = 1, u = 0.5 and v = 0.75

Hence, choose the correct set of answers in the multiple-choices listed:

1. Data Flow Diagram

The TOPCAR taxi company is developing a new computer system to be used to support taxi booking and corporate client credit accounts. This computer system aims to automate some manual processes and cut down on labour costs as TOPCAR has many customers from large corporate companies, e.g. CEO, and managers often need taxi trips to the airport. The following describes the activities that must be processed by the computer system:

A client company must first register and open a credit account with TOPCAR at TOPCAR’s website, in which case certain credit checks are made such as checking credit history of client company’s debt level. If the client company has no bad debt history, a credit account for the client company is set up.

At least 24 hours after successful account registration, authorized persons from such client company can request a taxi booking form TOPCAR’s website. When this happens, the availability of a taxi at the requested date and time is checked, as is the credit status of the client company checked. (Note that credit status in finance means a measure of a lender’s willingness to lend money to a particular person or organization, depending on their ability to repay).

If these two checks are successful, a booking is made, and a written confirmation is sent via SMS and emailed to client company. After the customer from the client company has used the taxi, the driver sends in a record of the work, including the cost, and this is added to client company’s account. (Note that driver is an outsourced worker from TOPCAR’s point of view.) At the end of each month, taxi bills are sent via SMS and emailed to client companies for settlement.

From the above description, draw a data flow diagram showing the flow of input information (and/or data) and output information (and/or data) to and from processes and database stores within this computer system and any external environmental elements that interact with this computer system. In this diagram, you must identify the following:

1. processes inside this computer system,                      
2. database stores, external environmental elements that interact with any of the processes identified

in (a)                                                 (5.5 marks)

3. input and output information (or data) to and from each of the processes, database stores, and external environmental elements identified in (a) and (b)        (7.5 marks)

(Hint: there are two environmental elements that interact with this computer system, and six main processes in this computer system)

Suppose as a language designer, you plan to implement a feature called “output-only” parameters. The expected semantics is that all output-only parameters are uninitialized when the callee starts execution; they can be used (both read and write) as other kinds of parameters within the callee; finally, the corresponding actual parameter in the caller is updated to the final values of the “output-only” parameters. Briefly describe one possible implementation of such “output-only” parameters

Create an array of ten strings. Write a program to join and split these strings. Feel free to use any whitespace character. Explain how the program works, when to use Python arrays, and when to use tuples, dictionaries, and sets. Explain how the program works and how it can be utilized to support an organization’s requirements.

Using python pls!!!!! Write a recursive function gcd(m,n) that returns the greatest common divisor of a pair of numbers. The gcd of m and n is the largest number that divides both m and n. If one of the numbers is 0, then the gcd is the other number. If m is greater than or equal to n, then the gcd of m and n is the same as the gcd of n and m-n. If n is greater than m, then the gcd is the same as the gcd of m and n-m.

Pls endevour to use recursive approach to this

C++ Visual Studio 2019

Part A :

Program Description:

Write a program to generate a report based on input received from a text file. Suppose the input text file student_grades.txt contains the student’s Last name , First name, SSN, Test1, Test2, Test3 and Test4. (25%)

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0

Generate the output Report File student_final.txt in the following format :

LastName FirstName   SSN Test1   Test2   Test3   Test4 Average FinalGrade

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0    78.25 .0   C+

The program must be written to use the enum letterGrade :

enum letterGrade {A_PLUS,A, A_MINUS,B_PLUS,B, B_MINUS, C_PLUS,C, C_MINUS,D_PLUS,D, D_MINUS,F } ;

Use the following function prototype for deriving letter grade :

letterGrade deriveGrade(double average) ;

The average is calculated as follows : (test1 + test2 + test3 + test4)/4.0

The function deriveGrade should derive the letterGrade of the student based on the following grading scale :

Also provide the following function :

         string convertToText(letterGrade grade) ; //This function converts a letterGrade type to a string type.

Requirement :

• The namespace ‘gradeOpt’ definition should contain the following members :(15%)
  1. the enum letterGrade definition,
  2. deriveGrade(..) function prototype and
  3. convertToText(…) function prototype
• Add the namespace ‘gradeOpt ‘ to the grade.h header file and the namespace member function definitions to the file grade.cpp file. (10%)

make a C++ program to calculate total water bill for a customer. The water company charges $250.00 for <=1000 gallons of water. Over 1000 gallons the company charges .99 / gallons

The program displays

Gallons of water used = xx

Exatra payment= xx

Total payment = xx

Write a program that does the following in order:

1. Ask user to enter a name

2. Ask the user to enter five numbers “amount1”, “amount2”, “amount3”, “amount4”, “amount5”

3. Calculate the sum of the numbers “amount1”, “amount2”, “amount3”, “amount4”, “amount5”

4. If the sum is greater than 0, print out the sum

5. If the sum is equal to zero, print out “Your account balance is zero”

6. If the sum is less than 0, print out “Your account is overdrawn” and the “negative amount”

7. Round all print values to 1 decimal place

Round your sum output to 2 decimal places

make a C++ program to calculate discount for a customer.

Question 3. A string p = p₁…p_n is a palindrome if it spells the same string when read backward, that is p_i = p_{n+1 –i} for 1≤ i ≤ n. Design an efficient algorithm for finding all palindromes (of all lengths) in a text. (The pseudo code the algorithm should be provided) (40 points)

The stages of the classical waterfall model for software development consist of requirements, design, implementation, testing, deployment, and maintenance. Why does picturing the development of software to run on mobile applications, business-based systems, or Internet environments help to ensure the success of the development effort? What might happen otherwise? What is the professionalism with respect to software engineering? What do you do, as a software engineer involved in a software systems development project, to ensure that the product is better because of your participation in the development effort?

Answer any 3 questions

Please write in Java and have two methods: the main method and the reverse word

Write a method that reads a line and reverses the words in the line (not the characters) using a stack. For example, given the following input:

The quick brown fox jumps over the lazy dog

you should get the following output:

dog lazy the over jumps fox brown quick The

Then create a main method to prompt the user to enter a line of words to be reversed using the previous reverse method.
