Introduction
Password complexity requirements can be enforced using password policies. IAM password policies can be used to ensure that the usersβ passwords are at least a given length. It is recommended that the password policy requires a minimum password length of 14 characters.
Setting a password complexity policy increases account resiliency against brute force login attempts. If password length requirements are not enforced, users with smaller and weaker passwords become much more vulnerable to brute force attacks.
Accounts that can be brute forced provide access to attackers and consequently access to all data and resources within. In case of accounts with administrative access, this could mean the compromise of all resources, data, and even business intellectual property.
In this article we will see how to update IAM password policy.
