All operating systems, including UNIX or Windows NT, are susceptible to attacks any time the Administrator accounts are compromised. The article states that this alleged security problem could enable a remote user to unscramble encrypted information, like a user password, and display it as plain text. You can log into the system and retrieve a user name and encrypted password only if you have administrator privileges. The issue relies on the existence of an Administrator account that has been rendered vulnerable by neglecting basic security guidelines. Every computer operating system is susceptible to security issues if basic security guidelines are not followed.
Security is achieved through a combination of technology and policy.
The Administrator account should not be used for casual use. The Domain controllers should be physically secured. Maintain a strong password policy. Rename the Administrator account. Never run untrusted programs while logged in as Administrator.
