The Active Directory “smart lockout” feature will help to frustrate password guessers. “Smart” Applications With Microsoft 365 Accounts It’s possible to customize the list, excluding passwords such as your company’s name and street address. The complexity requirement setting will lock out most of them, but having another layer of protection doesn’t hurt. Enable the “complexity requirements” setting, which requires passwords to have a mix of upper and lower case, numbers, and symbols.Įnable the “banned password list” to disallow the most obvious passwords. Longer passwords are much harder to guess. Set a minimum password length of at least 10 characters. Train users to create difficult passwords and protect them carefully. That does nothing to improve security, and it encourages people to create simpler passwords or write them down. Don’t make passwords expire periodically and force users to change them.

Some people create very weak ones, like “password” or “12345678.” A good password policy will keep the chances of password theft low. Keep Passwords Secure With Microsoft 365 AccountsĬreating good passwords is hard. Outlook and other mail clients should be set to use modern authentication. These old protocols include basic authentication for email (POP3 and IMAP). In addition to not supporting multi-factor authentication, the older protocols are more vulnerable to various attacks.

You should upgrade or replace any such application on general principles. The only reason to have it is an old application that doesn’t support modern authentication. The latest security defaults disable legacy authentication, and you should verify that it’s disabled for your organization. Some of the older ones don’t support MFA, and Microsoft calls them legacy authentication protocols. Microsoft 365 and Active Directory allow multiple authentication protocols. Indeed, criminals can trick mobile providers into creating duplicate SIMs for them, giving them access to a user’s phone number. Mobile apps provide better security than SMS confirmation. Whether it should be required for all accounts depends on the level of security your organization needs and the nature of the workforce.

MFA is especially important for administrators and other high-privilege accounts. Using an SMS message or a mobile application to confirm the user’s identity forces impersonators to get past two or more barriers. It’s easier than people think to steal or guess passwords. This is called two-factor authentication (2FA) or multi-factor authentication (MFA). Requiring users to confirm themselves in two ways makes accounts far more secure. Use Multi-Factor AuthenticationĮnabling basic security in Microsoft 365 starts at the login screen.

Here is how to establish basic security in Microsoft 365. Administrators should pay attention to all of the following points and periodically review how well the accounts and settings follow them. This means following practices that will minimize the chances of unauthorized access. Microsoft 365 is a very secure environment when used properly.
