In the last post “What is Two-Factor Authentication?” we discussed about various factors of authentication system including different examples. We also learnt about Knowledge Factor, Inherence Factor and Possession Factor.

Microsoft recently added a second step authentication mechanism in all their accounts as an extra security layer. This post will guide you to turn ON/OFF this security layer.

Two-factor authentication is a user authentication system where an user needs to provide two different factors to authorize the user’s identity. It is not a new concept and in many places we are knowingly or unknowingly using it for secure access.

There could be multiple factors too and that known as Multi-factor authentication. Today in this post we will learn basics about this type of authentication system.

Today I received this “Security Alert” from Microsoft via email and thought to share this with you. If you are using ASP.Net in your server, read this post to know about it to keep your server in good health from this DoS Attack. Sharing the email as it is in this post.

Microsoft is aware of detailed information that has been published describing a new method to exploit hash tables. Attacks targeting this type of vulnerability are generically known as hash collision attacks. Attacks such as these are not specific to Microsoft technologies and affect other web service software providers. This vulnerability affects all versions of Microsoft .NET Framework and could allow for an unauthenticated denial of service attack on servers that serve ASP.NET pages.
