Using PowerShell to secure Active Directory passwords

Step 1: Enable strong password policies

Modify AD policies to require complex passwords. The script below will require passwords to be at least 12 characters long.

Set-ADDefaultDomainPasswordPolicy -ComplexityEnabled $true -MinPasswordLength 12

Step 2: Enforce regular password changes

Set expiration policies. This forces password changes every 90 days.

Set-ADDefaultDomainPasswordPolicy -MaxPasswordAge 90 -MinPasswordAge 1

Step 3: Lock accounts after failed attempts

Reduce the risk of brute-force attacks by locking accounts after five failed login attempts for 30 minutes.

Set-ADDefaultDomainPasswordPolicy -LockoutThreshold 5 -LockoutDuration 30

Step 4: Notify users about security policies

Send a reminder email about strong passwords to keep users aware of security measures.

Send-MailMessage -To "allusers@domain.com" -From "admin@yourdomain.com" -Subject "Password Security Update" -Body "Reminder: Ensure your passwords meet security standards."
