| Detailed Description |
The password of a Domain Guest account is guessed, and it's possible to log into the system with the account.
Domain account is given logon privileges to a domain and access privileges to all resources in the domain for which they have been granted access. This account information is stored in the active directory on the domain controller. Account management and password management is important in preventing unauthorized access to your system. If the password of Guest account can be guessed, attackers can guess and log on the system easily using this account. And they may access restrictedly sensitive information and system resources with the guest privileges.
This check attempts to log on using hostname as the password remotely for only domain accounts that are part of the Guest group, and displays the name of the accounts that logged on successfully.
