Banned password list

A lot of security guidance recommends that you don't use the same password in multiple places, to make it complex, and to avoid simple passwords like Password You can provide your users with guidance on how to choose passwordsbut weak or insecure passwords are often still used. Azure AD Password Protection detects and blocks known weak passwords and their variants, and can also block additional weak terms that are specific to your organization.

To support your own business and security needs, you can define entries in a custom banned password list. When users change or reset their passwords, these banned password lists are checked to enforce the use of strong passwords. If your IT team hasn't enabled the ability to reset your own password, reach out to your helpdesk for additional assistance.

Specifically, the analysis looks for base terms that often are used as the basis for weak passwords. When weak terms are found, they're added to the global banned password list. The contents of the global banned password list aren't based on any external data source, but on the results of Azure AD security telemetry and analysis.

When a password is changed or reset for any user in an Azure AD tenant, the current version of the global banned password list is used to validate the strength of the password. This validation check results in stronger passwords for all Azure AD customers. The global banned password list is automatically applied to all users in an Azure AD tenant.

There's nothing to enable or configure, and can't be disabled. This global banned password list is applied to users when they change or reset their own password through Azure AD. Cyber-criminals also use similar strategies in their attacks to identify common weak passwords and variations. To improve security, Microsoft doesn't publish the contents of the global banned password list.

Some organizations want to improve security and add their own customizations on top of the global banned password list.

To add your own entries, you can use the custom banned password list. Terms added to the custom banned password list should be focused on organizational-specific terms such as the following examples:. When terms are added to the custom banned password list, they're combined with the terms in the global banned password list. Password change or reset events are then validated against the combined set of these banned password lists. The custom banned password list is limited to a maximum of terms.

It's not designed for blocking extremely large lists of passwords. To fully leverage the benefits of the custom banned password list, first understand how are passwords evaluated before you add terms to the custom banned list.

This approach lets you efficiently detect and block large numbers of weak passwords and their variants. Let's consider a customer named Contoso. The company is based in London and makes a product named Widget.

For this example customer, it would be wasteful and less secure to try to block specific variations of these terms such as the following:.

So how many passwords were correctly validated in either mode:. So to gather the statistics through an AD forest I have written a script that gathers the statistics from the RWDCs that are part of the specified scope. The script supports, three modes being: forest, domain specified and rwdc specified!

Independent of the scope, it also counts the total of every statistic property and presents it accordingly at the end or in the GridView through a separate entry at the end.

Today, I want to talk about a high-volume tactic: password spray. When I talk to security professionals in the field, I often compare password spray to a brute force attack. Brute force is targeted. And then trying those variants against an account to gain access. Password spray is the opposite. Adversaries acquire a list of accounts and attempt to sign into all of them using a small subset of the most popular, or most likely, passwords.

Until they get a hit. This blog describes the steps adversaries use to conduct these attacks and how you can reduce the risk to your organization. It starts with a list of accounts.

This is easier than it sounds. Most organizations have a formal convention for emails, such as firstname. This allows adversaries to construct usernames from a list of employees. If the bad actor has already compromised an account, they may try to enumerate usernames against the domain controller. Or, they find or buy usernames online. Data can be compiled from past security breaches, online profiles, etc. The adversary might even get some verified profiles for free!

Finding a list of common passwords is even easier. A Bing search reveals that publications list the most common passwords each year. Wikipedia lists the top 10, passwords. There are regional differences that may be harder to discovery, but many people use a favorite sports teams, their state, or company as a password. For example, Seahawks is a popular password choice in the Seattle area.

Once hackers do their research, they carefully select a password and try it against the entire list of accounts as shown in Figure 1. If the attack is not successful, they wait 30 minutes to avoid triggering a timeout, and then try the next password.
