    How to prevent password cracking

    Please follow the policies and processes:

    (1) To change with each new and existing systems in all the default password.
    (2) Do not let privileged user accounts on different systems use the same passwords.
    (3) Constantly changing passwords (in most organizations there is sensitive data in the system is set to once every 30 days to change your password, but when the personnel changes took place also change password).
    All the best.

    You need to strictly limited administrative access permissions, only the permissions granted to those who genuinely need access to people. Do not write down the password for the system (any password are case). Do not let the software script that contains the system-level account or password information. Best of luck.

According to the work of the staff to maintain user rights. When a staff into a particular project team, you'll need based on its role to create new accounts.

    If the system contains highly sensitive information and require the least amount of system access, you might consider the use of system-level password or hardware-based multi-factor tokens, and encryption and key protect them under. Note: Some companies need access to sensitive information to all employees to set multi-factor authentication mechanisms. Using the generated password or phrase (eg, "Philadelphia Phillies is the community the best baseball team") and not be limited to alphanumeric symbols. Instead of using the flag as much as possible with the digit 8 character password. Check and reply.

    You need to close or disconnect any attempt to access the system's back door, unless there are special needs (such as a modem, Citrix Access, etc.). You will placed in sensitive systems outside the core business and communications and to provide physical isolation (for cabinets, computer room, do the company lock, etc.). In the system restored to all of the backup media to be protected and entered into force. As part of system recovery, the old account will be restored, so need to ensure that old data does not contain the old authentication information. If it really turns the old authentication information, you need to do in a timely manner to their change, or delete operation. Proper combination of common sense and Safe to guide the team in collaboration with the IT department, will help you find the best way to protect your system password security. All the best.
