Align password length, complexity and rotation policies with NIST 800-63 B's guidelines in section 5.1.1 for Memorized Secrets or other modern, evidence based password policies.

Implement weak-password checks, such as testing new or changed passwords against a list of the top 10000 worst passwords.

Do not ship or deploy with any default credentials, particularly for admin users.

Where possible, implement multi-factor authentication to prevent automated, credential stuffing, brute force, and stolen credential re-use attacks.

How to prevent Broken Authentication Broken authentication User passwords are not properly hashed and salted, exposing every user’s password. Example #3: Passwords are not properly hashed and saltedĪn insider or external attacker gains access to the system’s password database. An attacker uses the same browser an hour later, and the user is still authenticated. Instead of selecting “logout” the user simply closes the browser tab and walks away. Example #2: Application session timeouts aren't set properly.Ī user uses a public computer to access an application. If an application does not implement automated threat or credential stuffing protections, the application can be used as a password oracle to determine if the credentials are valid.

The use of lists of known passwords, is a common attack. The goal of an attack is to take over one or more accounts and for the attacker to get the same privileges as the attacked user.īroken authentication examples Example #1: Credential stuffing User sessions or authentication tokens (particularly single sign-on (SSO) tokens) aren't properly invalidated during logout or a period of inactivity.

Does not properly invalidate Session IDs.Does not rotate Session IDs after successful login.Exposes Session IDs in the URL (e.g., URL rewriting).

Has missing or ineffective multi-factor authentication.Uses plain text, encrypted, or weakly hashed passwords (see A3:2017-Sensitive Data Exposure).Uses weak or ineffective credential recovery and forgot-password processes, such as "knowledge-based answers", which cannot be made safe.Permits default, weak, or well-known passwords, such as "Password1" or "admin/admin“.Permits brute force or other automated attacks.Permits automated attacks such as credential stuffing, where the attacker has a list of valid usernames and passwords.These types of weaknesses can allow an attacker to either capture or bypass the authentication methods that are used by a web application.
