Answer:
- with(open("numbers.txt")) as file:
- data = file.readlines()
- runsum = 0
- largest = 0
-
- for x in data:
- if(int(x) > largest):
- largest = int(x)
- runsum += largest
-
- print(runsum)
Explanation:
The solution code is written in Python 3.
Firstly, open a filestream for numbers.txt (Line 1) and then use readlines method to get every row of data from the text files (Line 2).
Create a variable runsum to hold the running sum of number bigger than the maximum value read up to that iteration in a for loop (Line 3).
Use a for loop to traverse through the read data and then check if the current row of integer is bigger than the maximum value up to that point, set the current integer to largest variable and then add the largest to runsum (Line 6 - 9).
At last display the runsum to console terminal (Line 11).
Answer:
1. Keeping a password with user name or password is very easy word.
2. Passwords should be kept strong so that it cannot be haccked. One should use upper case letters along with lower case letters and numeric and special characters to make the password strong.
3. The businesses usually run anti viruses in case of virus attack. In case of haccker attack businesses are temporarily shut down from their routine work and alternate business plan is activated which runs the business activities incognito version.
4. High profile passwords can be leaked as it is on the computer system which can be accessed from around the world.
Explanation:
The businesses should use DRP system in order to avoid complete shut down of business operations in case of a cyber attack. The passwords should be kept strong enough so that no one can crack the password and all employees should not be given complete access to business operations and planning activities. Employees access should be restricted to their job role.
Answer:
David L. Smith
Explanation:
Around March 26, 1999, the Melissa virus was released by David L. Smith
‘Melissa.A’ used social engineering techniques, since it came with the message “Here is the document you asked me for… do not show it to anyone”. In just a few days, she starred in one of the most important cases of massive infection in history, causing damage of more than 80 million dollars to American companies. Companies like Microsoft, Intel and Lucent Technologies had to block their Internet connections due to its action.
How it Works
When opening a document infected with the ‘Melissa.A’, the virus creates an e-mail with the following features:
Subject: Important Message From “sender name”
Text: Here is that document you asked for … do not show anyone else
Attachments: a file with a DOC.
The recipients of this message were the first 50 addresses ‘Melissa.A’ found in the address book in Outlook. This was the first macro virus that used this technique, until this moment there hadn’t been a virus that affected users by sending a Word document within an email.
What Happened
The creator of ‘Melissa.A’, David L. Smith, pleaded guilty but said he did not expect such high economic damage. This malware was created in memory of a topless dancer in Florida with whom he had fallen in love with.
Smith was sentenced to 10 years in prison.
