How Do I Handle a Weak Password Alarm?

Servers using weak passwords are exposed to intrusions. If a weak password alarm is reported, you are advised to change the alarmed password immediately.

Causes

  • If simple passwords are used and match those in the weak password library, a weak password alarm will be generated.

  • A password used by multiple member accounts will be regarded as a weak password and trigger an alarm.

Checking and Changing Weak Passwords

  1. Log in to the management console.

  2. Choose Prediction > Baseline Checks and click the Common Weak Password Detection tab.

  3. Check the server, account name, account type, and usage duration of the weak password. Log in to the server and change the password.
