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
- Log in to the management console.
- In the upper left corner of the page, select a region, click , and choose Security & Compliance > HSS.
- Choose Risk Management > Baseline Checks and click the Common Weak Password Detection tab.
