Password security best practices in PowerShell
According to the 2019 Data Breach Investigation Report by Verizon, stolen credentials are the major cause of data breaches. To safeguard passwords from cyberattacks like brute-force or password spray, compliance regulations like NIST define password security rules to ensure password complexity.
A brief summary of 2019 NIST password security guidelines:
- The minimum and maximum length of the passwords should be eight and sixty-four respectively.
- Permit the usage of printable ASCII characters (including spaces), and Unicode characters.
- Blacklist commonly used words, dictionary words, and breached passwords.
- Restrict the use of repetitive or keyboard sequences.
- Offer guidance, such as a password strength meter, to help users choose a strong password.
- Enforce account lockouts after ten failed authentication attempts.
- Enforce two-factor authentication (2FA) with advanced authentication techniques like Google or Microsoft Authenticator.
All of the above regulations can be enforced on both on-premises and cloud users using ADSelfService Plus, the self-service password management and single sign-on solution. However, it is highly complex to execute the same using PowerShell.
