Final answer:
To increase the security of Bob's account, you should require users to set stronger passwords upon initial logon and train them not to use easily guessable passwords. Implementing multi-factor authentication for all users is also a recommended security measure.
Step-by-step explanation:
To increase the security of Bob's account, you should require users to set a stronger password upon initial logon. This means implementing password policies that enforce the use of complex passwords, such as a combination of uppercase and lowercase letters, numbers, and symbols. By doing this, you ensure that passwords are more difficult to guess or crack.
In addition to setting stronger passwords, it is also important to train users not to use passwords that are easy to guess. This includes avoiding common words, personal information, or predictable patterns. Educating users on password best practices can help them understand the importance of strong password security.
While implementing multi-factor authentication for all users would further enhance the security of accounts, it is not specifically mentioned in this scenario. However, it is a highly recommended security measure as it adds an extra layer of protection by requiring users to provide additional verification factors, such as a fingerprint or a one-time code, in addition to their password.
