Two-factor authentication system

What is the Windows desktop two-factor authentication process?

Double protection against security vulnerabilities

With the increasing number of security vulnerabilities every day, it is no longer an option to protect user accounts only by username and password. In addition to making passwords stronger, a more feasible solution is to add an extra security layer to filter unauthorized users. Two-factor authentication-a method of authenticating users with information they know and have, makes all this possible.

Log in to Windows using ADSelfServicePlus.

Enable? ADSelfServicePlus？ "? Windows login TFA? Function, users must authenticate in two consecutive phases before they can access their Windows computers. The first level of authentication is through what they know: their usual Windows credentials. The second level of authentication (what they have) can be done in one of the following ways:

TOTP certification

Security issues based on AD

Windows login TFA ensures that even if the password is leaked, it will not pose any risk to sensitive data. In other words, even if unauthorized users get the user's password, they still need to access the user's phone or email to get the verification code. In addition, verification codes and identity verification codes based on SMS and email from DuoSecurity and RSASecurID are unique for each user. These codes can only be used once, and will expire if they are not used within a certain period of time.

After Windows login TFA is enabled, TFA will be added to all Windows local and remote login attempts.

ADSelfServicePlus supports Windows login TFA on the following operating systems:

WindowsVista and later.

WindowsServer2008 and later.

What are the advantages and disadvantages of Ningdun two-factor authentication system?

The biggest advantage is good compatibility. For all kinds of network devices, operating systems, fortresses, websites and applications, Ningdun two-factor authentication system can seamlessly support AD/LDAP account sources and Web built-in account sources. , without changing the existing account management mode, to achieve rapid docking. Meet the national security 2.0 compliance requirements, and have the national secret SM3 algorithm qualification; The disadvantage is that it is a bit expensive.

What is two-factor authentication?

Two-factor authentication is a system using time synchronization technology, which uses one-time password based on time, event and key instead of traditional static password. Each dynamic password card has a unique key and is stored in the server at the same time. During each authentication, the dynamic password card and the server calculate the authentication dynamic password according to the same key, the same random parameters and the same algorithm, which ensures the consistency of passwords and realizes the authentication of users.

Because the random parameters of each authentication are different, the dynamic password generated each time is different. Because the randomness of parameters in each calculation ensures the unpredictability of each password, the security of the system is guaranteed in the most basic password authentication. Solve the heavy losses caused by password fraud, prevent malicious intruders or man-made sabotage, and solve the intrusion problem caused by password leakage.

Extended data:

Two-factor authentication is usually used in the following situations:

1, wireless network protection;

2. Two-factor authentication of network equipment such as routers, switches and firewalls;

3. Two-factor authentication for various VPNs;

4. Protect UNIX, Linux and Windows operating systems;

5. Protect different network servers;

6. Protect various C/S application systems;

What is Nington's two-factor certification? Any good suggestions?

Ningdun two-factor authentication system is a system that provides dynamic password generation, authentication and audit functions. It combines the dynamic password with the password authentication of the original account to realize the two-factor authentication guarantee, effectively protect the security of enterprise application systems, and help enterprises realize the audit of application access accounts.

Ningdun two-factor authentication system can provide more than ten forms of dynamic password authentication, such as SMS authentication, hardware token, mobile phone token, mobile phone push token and H5 token, and support password authentication of third-party accounts, such as built-in /AD/LDAP. Users can choose the appropriate dynamic password form according to their own application conditions, which is a two-factor authentication solution with perfect combination of security and convenience.

Excuse me, how is the two-factor authentication of Office365 realized? Do you have any recommendations?

On the basis of the original static password authentication in Office365, a second protection is added. Ningdun two-factor authentication combined with ADFS joint authentication can improve account security and avoid account theft caused by password sharing/disclosure or cracking, and can also hold individuals accountable in case of security incidents and strengthen user login authentication audit.

The specific implementation process of Office365 two-factor authentication is that when employees visit office365, they first jump to the ADFS login page for domain authentication. Enter the dynamic password verification page after successful verification. The ADFS server sends the dynamic password identity information to the Ningdun authentication server for verification. Jump back to office365 after verification. At this point, the two-factor authentication login process is completed.

Why should enterprises do two-factor certification?

Simply put, two-factor authentication is an authentication system that can only work by combining what you know with what you have. For example, a bank card that withdraws money from an ATM is an example of a two-factor authentication mechanism. You need to know the combination of the withdrawal password and the bank card before you can use it.

At present, the mainstream two-factor authentication systems are all based on time synchronization, and DKEY two-factor authentication system and RSA two-factor authentication system have higher market share. Because DKEY has increased the support for SMS password authentication and SMS+token mixed authentication, DKEY two-factor authentication system is more competitive than RSA.
