Detection of Password Weaknesses

high

Description

Multiple problems can arise with Active Directory account passwords (insufficient complexity, obsolete cryptography, blank, reused, leaked...), leading to a decrease in Active Directory security by allowing "brute-force", "password spraying" and "lateral movement" attacks.

Solution

Good administrative practices for domain user passwords involve using strong and unique passwords, avoiding unchanged default values that relate to domain-authenticated accounts, and securely storing passwords with robust algorithms.
