Which of the following passwords would provide the best defense against a brute-force attack?
Which of the following passwords would provide the best defense against a brute-force attack?
The password 'ThisIsMyPasswordForWork' provides the best defense against a brute-force attack. The primary factor in resisting brute-force attacks is the length of the password: longer passwords have exponentially more possible combinations, making them significantly harder to crack. Although complexity with a combination of uppercase letters, lowercase letters, numbers, and symbols is important, the length is the most critical aspect. With 23 characters in length, 'ThisIsMyPasswordForWork' offers a vastly larger number of possible combinations compared to shorter options.
If you wanna be mathematical: Uppercase letters: There are 26 uppercase letters (A-Z). Lowercase letters: There are 26 lowercase letters (a-z). Numbers: There are 10 digits (0-9). Symbols: Let's assume a set of commonly used symbols, such as !"#$%&'()*+,-./:;<=>?@[]^_`{|}~. This set contains 32 symbols. ThisIsMyPasswordForWork contains 26+26 (uppercase and lowercase) possible characters, and is 23 digits long. Thats 52^23 possible combinations, or 3.2x10^29. T5!8j5 contains uppercase, lowercase, numbers and symbols, but is only 6 digits long, this allows for 6.8x10^11 combinations. Therefore A is more secure when it comes to bruteforcing.
A. ThisIsMyPasswordForWork This password would provide the best defense against a brute-force attack because it is the longest. Length is the key factor here. A. ThisIsMyPasswordForWork would take many more combinations to crack than D. T5!8j5
D. T5!8j5 The password "T5!8j5" would provide better defense against a brute-force attack compared to the other options. Here's why: Length: Longer passwords are generally more secure. "T5!8j5" is shorter than option A but still reasonably good in terms of length. Complexity: It includes a mix of uppercase and lowercase letters, numbers, and special characters. This complexity makes it more resistant to various types of attacks, including brute-force.
Tough question for him?
ChatGPT D. T5!8j5 Explanation: Complexity: The password "T5!8j5" appears to be more complex, with a mix of uppercase letters, numbers, and special characters. This complexity increases the strength of the password and makes it more resistant to brute-force attacks. Length: While longer passwords are generally more secure, in this case, the shorter password "T5!8j5" is still strong due to its complexity.
Did you just ask chat GPT about the two answers of A or D or did you include all the questions? With this logic answer B. is better with more complexity and length than answer D.
The correct answer is: D. T5!8j5 Let's evaluate the options: A. ThisIsMyPasswordForWork: This password is long, but it's based on a phrase and uses common words, making it vulnerable to dictionary attacks and brute-force attacks. B. Qwerty!@#$: This password is complex, but it's based on a common keyboard pattern (QWERTY) and is relatively short, making it vulnerable to brute-force attacks. C. Password!1: This password is a variation of a common word ("password") and is relatively short, making it vulnerable to brute-force attacks. D. T5!8j5: This password is random, complex, and long (although it could be longer). It's a good example of a strong password that would provide a good defense against brute-force attacks.
based on password checker, It takes 18 days for option D to be broken while it only takes 9 hours for A. So The correct answer is D.
Option A is longer, should be harder to brute force
D was my vote but kinny4000 has convinced my to vote A.
I am going B on this one. The question ask to protect against brute force, not dictionary attacks. Answer B, is just as complex as answer D and is longer. Answer A is not as complex.
D looks correct
Qwerty!@#$ is defineltly a dictotionary work with !@#$ translating to 1234 making it easy for an attack
it is a dictionary word but this question is not asking to protect against dictionary attacks but rather brute-force attacks. I would agree if it said against dictionary attacks or just password management in general.
