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.SOMEONE HACKED MY ROBLOX ACCOUNT...
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:.
Instead, it's much more efficient and secure to block only the key base terms, such as the following examples:.
Tutorial: Configure custom banned passwords. Azure AD Password Protection helps you defend against password spray attacks. Most password spray attacks don't attempt to attack any given individual account more than a few times.Hi I've been tasked with prohibiting certain passwords in AD, Like a blacklist of passwords such as Password! I had looked online but the explanations are too complex and I need a more layman's understanding initially so I can see if I need to research or go 3rd party From what I understand so far I need to create a group policy - default domain policy.
Is this a complex operation? Is it worth taking the risk doing this? What could be typical negative outcomes? Are 3rd party solutions preferable or Is that a waste of money for something that can implement myself?
Id appreciate any info, big picture overview so I can consider an approach I can rustle up a Powershell script but C if that is the only option is beyond me presently. There are third party options to use smart card or tokens. That way you can enforce better security without having to worry about week passwords.
Pretty much as you say, you need a 3rd party DLL that hooks into your DC's so it is called any time a password changes, you might be able to use this solution and then just substitute the haveibeenpwned text file with your own list of banned passwords.
I haven't tried this DLL myself so can't comment on any potential issues or crashes etc. Not the answer you are looking for but below are two good third party software. Easier to configure and manage than messing around with scripting.

The US technology firm has created a dynamically-updated list of terrible passwords, which it will not let you use when registering for an account online.
In a new blog post, Microsoft explains that it is putting the insights it has gleamed from millions of leaked passwords to good use. Rather than provide some loose guidelines about password length and complexity, the Redmond firm will not let you use any of the commonly used passwords. The list of offenders will be continually updated based on new leaks, so when people start to shift to other easy-to-guess passwords — these will also be banned. The company says the feature has already rolled out to Microsoft Account Service — which means it works across Outlook, Xbox, and OneDrive.
You probably won't notice the difference until you pick a really simple password, like or password, at which point the system will kick-in and you'll be prompted to pick something better.
For example, take the first letter of each word in your favourite song lyric, phrase or poem — and use those letters, which appear like a random jumble, as your password. A password manager is another way to generate and securely store unique passwords with letters, symbols and numbers.

Maybe your password is as easy as "1, 2, 3". Twitter has banned passwords notas heard in the last few days, because "password" is repeated twice in the list to prevent lazy users from using common passwords and, in part, force them to elevate their level of password security. Simply, go to Twitter's sign up page, right-click on the browser, select "view source" or "view page source" for Firefoxand search for "twttr. It's apparent that Twitter is trying to create a "cork on the fork" safety measure but Twitter users are still expected to know how to make strong passwords.
There are tools available to check your password, like Microsoft's Password Checkerto determine if a passord is strong enough. Weak and common passwords like "", "", "welcome", "monkey" or anything remotely similar are totally unacceptable.
As more Twitter security woes and meltdowns continue to loom ahead, Twitter users should take initiative and use a strong password as the first step to protect their Twitter account.

Sign Me Up Now! Posted by Jorge on More detailed info about the events can be found here. If you therefore delete events or that RWDC is decommissioned for some reason, the statistics are lost. Remember, there are two modes, each mode has 2 possible actions, and multiple outcomes are possible that contribute to the statistics.
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. You can therefore see the statistics per RWDC and in total. You can download the script from here. You can follow any responses to this entry through the RSS 2.

These passwords are easy to guess, and weak against dictionary-based attacks. To enforce strong passwords in your organization, the Azure Active Directory Azure AD custom banned password list let you add specific strings to evaluate and block.
A password change request fails if there's a match in the custom banned password list. Azure AD includes a global banned password list. The contents of the global banned password list isn't based on any external data source. Instead, the global banned password list is based on the ongoing results of Azure AD security telemetry and analysis. When a user or administrator tries to change or reset their credentials, the desired password is checked against the list of banned passwords.
The password change request fails if there's a match in the global banned password list. You can't edit this default global banned password list. To give you flexibility in what passwords are allowed, you can also define a custom banned password list. The custom banned password list works alongside the global banned password list to enforce strong passwords in your organization. Organizational-specific terms can be added to the custom banned password list, such as the following examples:.
When a user attempts to reset a password to something that's on the global or custom banned password list, they see one of the following error messages:.

The custom banned password list is limited to a maximum of terms. It's not designed for blocking large lists of passwords. To maximize the benefits of the custom banned password list, review the custom banned password list concepts and password evaluation algorithm overview. Let's enable the custom banned password list and add some entries.
You can add additional entries to the custom banned password list at any time. Sign in to the Azure portal using an account with global administrator permissions. Search for and select Azure Active Directorythen choose Security from the menu on the left-hand side. Under the Manage menu header, select Authentication methodsthen Password protection. Add strings to the Custom banned password listone string per line. The following considerations and limitations apply to the custom banned password list:.When hackers plan an attack, they often engage in a numbers game.
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.
