A script is a program that can automate tasks or perform actions on a computer system. A script can be used to attempt multiple login attempts with different credentials, either randomly or from a list of known or guessed usernames and passwords. This can be done to gain unauthorized access to a system or to test its security12.

Users 4 and 5 are not using their credentials to transfer files or run tasks, because the report shows that they have failed login attempts on multiple servers. If they were authorized users, they would not have failed login attempts. Also, transferring files or running tasks does not require multiple login attempts on different servers.

A bot is a software application that runs automated tasks over the Internet. A bot can also be used to perform brute-force attacks, which are repeated attempts to guess a password or other authentication information. However, a bot would not use login credentials in a script, but rather generate random or common passwords to try3.

The Internet usage trend report shows that User 4 has an unusually high amount of data downloaded compared to other users. User 4 downloaded 2.5 GB of data in one day, while the average data downloaded by other users was around 0.2 GB. This could indicate that User 4 is engaged in some suspicious or malicious activity, such as downloading unauthorized or illegal content, exfiltrating sensitive data, or installing malware. Therefore, the security analyst should investigate User 4 further to determine the nature and source of the data downloaded.

 The security analyst should implement a control that uses built-in functions from libraries to check and handle long numbers properly. This will help prevent integer overflow vulnerabilities, which occur when a value is moved into a variable type too small to hold it. For example, if an integer variable can only store values up to 255, and a value of 256 is assigned to it, the variable will overflow and wrap around to 0. This can cause unexpected program behavior or lead to buffer overflow vulnerabilities if the overflowed value is used as an index or size for memory allocation1. Built-in functions from libraries can help avoid integer overflow by performing checks on the input values and the resulting values, and throwing exceptions or errors if they exceed the limits of the variable type2.
