Consider the following general code for allowing access to a resource:

Margaret [11]

Answer:

a) The code allows access even when IsAccessAllowed(...) method fails.

b) Either use If

(dwRet = ACCESS_ALLOWED)

or use

if (dwRet == NO_ERROR)

to avoid flaw

Explanation:

Lets first see what the code chunk does:

DWORD dwRet = IsAccessAllowed(...);

if (dwRet == ERROR_ACCESS_DENIED) {

// Security check failed.

// Inform user that access is denied.

} else {

// Security check OK.

}

In the given code, DWORD is basically a data type for double word type integers and this is defined in windows.h

So there is DWORD type variable dwRet that is assigned a method calls.

The method is IsAccessAllowed() which checks if the access is allowed to user.

if (dwRet == ERROR_ACCESS_DENIED) condition basically checks if the value of DWORD type variable dwRet is equal to ERROR_ACCESS_DENIED

If this condition evaluates to true then the security checks fails and user is informed via some message or action that the access is denied. But when the if condition evaluates to false then the else part executes which allows access.

So basically this chunk of code checks if the error ERROR_ACCESS_DENIED is returned.

Now the flaw in this program is what if the method IsAccessAllowed() by any reason. The reasons can be system failure or the memory failure. In memory failure case for example, the system returns out of memory error. So this means that the error is not ERROR_ACCESS_DENIED. Instead it is out of memory error. So in such a case the user is allowed access as the if condition evaluates to false and else part executes. So if any other error is produced due to some reason like mentioned above, then user has unrestricted access.

This shows that the doe should not check for the failure or rely on checking ERROR_ACCESS_DENIED to allow access but instead it should check for success. Code should only give access privilege if access is allowed successfully or no error is produced.

So to avoid this flaw the code is altered as:

DWORD dwRet = IsAccessAllowed(...);

If (dwRet = ACCESS_ALLOWED) {

//Security check OK.

} else {

//Security check failed.

//Inform user that access is denied.

}

This will only allow access if ACCESS_ALLOWED evaluates to true and success is checked instead of failure here

You can also alter the if condition as:

If (dwRet = No_Error)

If (dwRet = 0)

The above if conditions checks if the access is allowed or if no error is produced. Only then it will allowed access otherwise not. So the access check is a success is checked first and failure (for any reason). The user is allowed access only if there is no error otherwise user is not allowed access.

Design a program that asks the user to enter a store’s sales for each day of the week. The amounts should be stored in an array.

sdas [7]

Answer:

Program given below

Explanation:

Total Sales

Assign the values of the variable as “Enter the store sales for Sunday” in Sun

Assign the values of the variable as “Enter the store sales for Monday” in Mon

Assign the values of the variable as “Enter the store sales for Tuesday” in Tue

Assign the values of the variable as “Enter the store sales for Wednesday” in Wed

Assign the values of the variable as “Enter the store sales for Thursday” in Thu

Assign the values of the variable as “Enter the store sales for Friday” in Fri

Assign the values of the variable as “Enter the store sales for Saturday” in Sat

Assign the values for the variable in array as [Sun, Mon, Tue, Wed, Thu, Fri, Sat]

Initialize tot = 0

Use the loop for calculating the total sales for the week,

for total_sales in store_sales:

tot += total_sales

then display the result as,

print "\n Total week sales = %2.f " %tot

sun = int(input("\n Enter the store sales for Sunday: "))

mon = int(input("\n Enter the store sales for Monday: "))

tue = int(input("\n Enter the store sales for Tuesday: "))

wed = int(input("\n Enter the store sales for Wednesday: "))

thu = int(input("\n Enter the store sales for Thursday: "))

fri = int(input("\n Enter the store sales for Friday: "))

sat = int(input("\n Enter the store sales for Saturday: "))

store_sales = [sun, mon, tue, wed, thu, fri, sat]

tot = 0

for store_sale in store_sales:

tot += store_sale

print "\n Total Week Sales: %2.f" %tot

We will have the following output:

OUTPUT 

 Enter the store sales for Sunday: 45

Enter the store sales for Monday: 56

Enter the store sales for Tuesday: 89

Enter the store sales for Wednesday:78

Enter the store sales for Thursday: 45

Enter the store sales for Friday: 12

Enter the store sales for Saturday: 23

Total Week Sales: 348
