Complete Question:
A network security analyst received an alert about a potential malware threat on a user’s computer. What can the analyst review to get detailed information about this compromise? Check all that apply.
A. Logs.
B. Full Disk Encryption (FDE).
C. Binary whitelisting software.
D. Security Information and Event Management (SIEM) system.
Answer:
A. Logs.
D. Security Information and Event Management (SIEM) system.
Explanation:
If a network security analyst received an alert about a potential malware threat on a user’s computer. In order to get a detailed information about this compromise, the analyst should review both the logs and Security Information and Event Management (SIEM) system.
In Computer science, logs can be defined as records of events triggered by a user, operating system and other software applications running on a computer. Log files are used to gather information stored on a computer such as user activities, system performance and software program.
Security Information and Event Management (SIEM) system is the process of gathering and integration of all the logs generated by a computer from various software application, service, process, or security tool.
These logs collected through the SIEM are shown in a format that is readable by the security analyst and this help in real-time detection of threats.
Hence, logs and SIEM systems are important tools for network security analyst for detection of threats in real-time and event management functions.
The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?
The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?
def is_positive(number):
if _____ :
return _____
Answer:
def is_positive(number):
if (number > 0):
return True
else:
return "None"
---------------------------------------------------------------------------------
Code Test and Sample Output:print(is_positive(6))
>> True
print(is_positive(-7))
>> None
----------------------------------------------------------------------------------
Explanation:The code above has been written in Python.
Now, let's explain each of the lines of the code;
Line 1: defines a function called is_positive which takes in a parameter number. i.e
def is_positive(number):
Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e
if (number > 0):
Line 3: returns a boolean value True if the number is positive. i.e
return True
Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e
else:
Line 5: returns a string value "None" if the number is not positive. i.e
return "None"
All of these put together gives;
===============================
def is_positive(number):
if (number > 0):
return True
else:
return "None"
================================
An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e
print(is_positive(6)) = True
print(is_positive(-7)) = None
Following are the python program to check input number is positive or negative:
Program:def is_positive(n):#defining the method is_positive that takes one variable in parameter
if (n > 0):#defining if block that check input number is positive
return True#return boolean value that is True
else:#else block
return "None"#return string value
n=int(input("Enter number: "))#defining n variable that input a number
print(is_positive(n))#using print method that calls and prints method return value
Output:
please find the attached file.
Program Explanation:
Defining the method "is_positive" that takes one variable "n" in the parameter.Inside the method, if conditional block is defined that checks the input number is positive, if it's true, it will return a boolean value that is "True". Otherwise, it will go to the else block, where it will return a string value that is "None".Outside the method, the "n" variable is declared to be an input number.After the input value, a print method is used that calls the "is_positive" method and prints its return value.Find out more about the method here:

Implement the function:
string get_ap_terms(int a, int d, size_t n);
which returns a string containing the first n terms of the arithmetic progression (AP) as a sequence of comma-separated values.
Answer:
This is written in C++
Check comments for explanations
Program starts here
#include<iostream>
#include<string>
using namespace std;
//The function get_ap_terms begins here
string get_ap_terms(int a, int d, int size_tn)
{
// This line initializes the expected string to empty string
string result = "";
//The for iteration loops through the number of terms the function is expected to return
for(int i = 1; i<= size_tn;i++)
{
//This line checks if the loop is less than the number of terms
if(i < size_tn)
{
//This string gets the current term of the progression
result+=to_string(a)+ ", ";
//This line calculates the next term
a+=d;
}
else
{
//This line calculates the last term
result+=to_string(a);
}
}
//This line returns the string containing the first n terms of the arithmetic progression
return result;
}
//The main function starts here
int main()
{
//This line declares the first term (a), the common difference (d) and the number of terms (size_tn)
int a,d,size_tn;
//This line prompts the user for the first term
cout<<"First Term: ";
//This line gets the first term
cin>>a;
//This line prompts the user for the common difference
cout<<"Common Difference: ";
//This line gets the common difference
cin>>d;
//This line prompts the user for number of terms
cout<<"Number of Terms: ";
//This line gets the number of terms
cin>>size_tn;
//This line calls the function to print the string containing the first n terms
cout<<get_ap_terms(a, d, size_tn);
return 0;
}
//Program ends here

Non-employees are allowed in the store before the store opens and after
closing time.
True
False
SUBMIT
Answer:
