Which of the following attack types can be prevented by requiring letters and numbers in password?
A. brute force attacks
B. dictionary attacks
C. smurf attacks
D. rainbow attacks
B
Explanation : A dictionary attack occurs when attackers use a dictionary of common words to discover passwords. An automated program uses the hash of the dictionary word and compares this hash value to entries in the system password file. You should implement a security rule that says that a password must NOT be a word found in the dictionary to protect against these attacks. Inserting numbers and other characters can also thwart these attacks.
