Cloud Security: How Authentication Policies Can Help Fight Password Spray Attacks
In today’s world, security is a top priority for businesses of all sizes. As a cloud architect, it is important to stay up to date on the latest threats and how to protect yourself from them. One of the biggest threats today is password spraying, a type of attack that has become increasingly popular with hackers. This article will discuss the basics of password spraying and explain how authentication policies can be used to help protect against it.
What is Password Spraying?
Password spraying is a type of attack that attempts to guess a user’s password by trying a large number of commonly used passwords. Hackers use this method because it is much less likely to trigger security alerts than brute force attacks, which try a large number of passwords one at a time.
How Authentication Policies Can Help
Authentication policies are an effective way to protect against password spraying. By creating an authentication policy, you can control the number of failed login attempts that a user can make before their account is locked out. This prevents hackers from guessing passwords by trying a large number of passwords in a short amount of time.
Implementing an Authentication Policy in Exchange Online
To create an authentication policy in Exchange Online, you will need to use PowerShell. The first step is to connect to Exchange Online by using the Connect-ExchangeOnline cmdlet. Once you are connected, you can use the New-AuthenticationPolicy cmdlet to create a new authentication policy.
Password spraying is a common type of attack used by hackers to gain access to accounts. Authentication policies are a great way to protect against these attacks by limiting the number of failed login attempts before an account is locked out. Implementing an authentication policy in Exchange Online is easy to do with PowerShell and can help ensure that your accounts are secure.
