What are the steps involved in an authentication process?

There are two main steps in authentication: first is the identification, and the second is the central authentication. In the first step, the actual user's identity is provided in user ID and validation. However, just because the first step is successful, doesn't mean that the user have been authenticated.

What are the 3 authentication methods?

The three authentication factors are: Knowledge Factor – something you know, e.g., password. Possession Factor – something you have, e.g., mobile phone. Inherence Factor – something you are, e.g., fingerprint.

What is face authentication?

Facial authentication uses a face scan done by a human on any device with a front-facing camera to prove they are who they say they are. For face authentication to be secure, it needs to verify that the user is the right person, a real person, and that they are authenticating right now. This is what iProov’s Genuine Presence Assurance technology delivers.

Why is authentication important?

Ultimately, authentication is needed to restrict and allow access to personal information and accounts.

What happens if your authentication process takes too long?

Completion rates: If your authentication process asks the user to follow too many instructions, or if it takes too long, or it needs repeated attempts before it succeeds, there’s a high risk of drop-offs and lost business. This impacts any organization, whether it’s a retailer dealing with abandoned baskets or citizens failing to return to access online government services.

Why are passwords not secure?

In recent years organizations have started to move away from knowledge-based authentication. Passwords are not secure, because they can be shared, guessed or stolen. Passwords also cause user frustration, because they are easily forgotten. This ultimately leads to drop-off and poor completion rates.

Face authentication can also be done on general-purpose hardware. Any smartphone or computer or other devices with a user-facing camera can support face authentication, while fingerprint or iris scans need specialist hardware.

What is remote access server?

Remote access servers can be configured as dial-in servers or VPN servers. Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. Windows remote access servers support the following set of authentication methods: 1 Password Authentication Protocol (PAP) 2 Challenge Handshake Authentication Protocol (CHAP) 3 Microsoft's implementation of CHAP (MS-CHAP) 4 Updated version of MS-CHAP (MS-CHAP2) 5 Extensible Authentication Protocol/Transport Layer Security (EAP/TLS)

What does authenticator do?

The authenticator also calculates the hash value and compares the client's response with its own calculation. If the values match, the connection is established.

What is EAP TLS?

EAP/TLS provides for use of more secure authentication methods such as smart cards, Kerberos, and digital certificates, which are much more secure than the user name/password authentication methods above. It's defined in RFC 2716.

What is the protocol used for dial in VPN?

What is a RADIUS authorization?

Authorization refers to granting specific services to users based on their authenticated identity; restrictions can be imposed on certain users. Accounting refers to tracking the use of the network by users and can be done for billing, management, or security purposes. RADIUS is defined in RFCs 2865 and 2866.

Is MS-CHAP v2 secure?

Version 2 adds such features as mutual (two-way) authentication of both client and server, as well as stronger encryption keys. MS-CHAP v2 is more secure than CHAP for Windows systems.

Can you have multiple remote access servers on Windows 2003?

Windows 2003 Server Enterprise Edition's IAS implementation puts no limits on the number of RADIUS clients you can configure or on the number of RADIUS server groups you can have. Even more importantly, a single RADIUS server can support many remote access servers, so that as you add additional dial-in and/or VPN servers, their users are all still authenticated through one central point: the RADIUS server. The fact that the authentication server is separate from the access server (s) makes this both more secure and more scalable than other authentication methods.

What is remote credential guard?

It's an incredibly clever mechanism that prevents clients from sending any primary credentials to the target machine, therefore mitigating any risk of leaking them if the target is compromised.

Why does RDP take so long?

It turns out RDP emulates the smart card hardware and literally passes hardware commands back and forth over the channel. This is, incidentally, why it takes so long for RDP sessions to start when using smart cards. It's proxying hardware commands over the channel encrypted to that session key. It's kinda wild.

What does LSA ask client?

Over the channel the target LSA asks the client to ask (ish) the client LSA for a ticket to whatever the target needs. The client obliges, and forwards the ticket. The target now has a ticket, and never saw the creds. It's ingenious.

Do remote connections go through cached logon?

There are some notable differences here though. For instance remote connections never go through cached logon.

What encryption does Kerberos use?

Kerberos uses DES encryption to authenticate a user when logging in to the system.

What is authentication process?

The authentication process is framed by client requests and server responses. The “authentication” request actually includes elements of authorization (access rights are checked as well). A request contains:

How does the client know which authentication method to start with?

But how does the client know which methods to start with? The client starts with a “none” authentication request, which prompts the server to reply with a list of the authentication methods the client can choose to continue the process. In other words, if the server requires any authentication at all, the “none” method fails. If not, a SUCCESS is immediate and a lot of time is saved.

What are the three methods of authentication?

The three defined methods are public-key, password, and host-based authentication . The authentication process is framed by client requests and server responses.

How does MS calculate authentication?

MS calculates an authentication result using CAVE and transmits that result back to the serving system when it accesses the system for registration, call origination , or paging response purposes .

What is the secret number of an authentication algorithm?

The authentication process and algorithm are based on the following two secret numbers: 1. Authentication key (A-key) (64-bit) 2. Shared secret data (SSD) (128-bit) The A-key is a 64-bit secret number that is the permanent key used by the authentication calculations in both the MS and the AC.

What is the authenticating target of a domain?

In the case of a domain-joined computer, the authenticating target is the domain controller. The credentials used in authentication are digital documents that associate the user's identity to some form of proof of authenticity, such as a certificate, a password, or a PIN.

How does a client computer participate in a network domain?

For example, client computers running a Windows operating system participate in a network domain by communicating with a domain controller even when no human user is logged on. To initiate communications, the computer must have an active account in the domain. Before accepting communications from the computer, the LSA on the domain controller authenticates the computer's identity and then constructs the computer's security context just as it does for a human security principal. This security context defines the identity and capabilities of a user or service on a particular computer or a user, service, or computer on a network. For example, the access token contained within the security context defines the resources (such as a file share or printer) that can be accessed and the actions (such as Read, Write, or Modify) that can be performed by that principal - a user, computer, or service on that resource.

What is Winlogon session 0?

The instances of Winlogon for an interactive logon run in Session 0. Session 0 hosts system services and other critical processes, including the Local Security Authority (LSA) process.

How does Winlogon logon work?

With the credential provider architecture, Winlogon always starts Logon UI after it receives a secure attention sequence event. Logon UI queries each credential provider for the number of different credential types the provider is configured to enumerate. Credential providers have the option of specifying one of these tiles as the default. After all providers have enumerated their tiles, Logon UI displays them to the user. The user interacts with a tile to supply their credentials. Logon UI submits these credentials for authentication.

What is GINA in Windows Server 2008?

In Windows Server 2008 and Windows Vista, the Graphical Identification and Authentication (GINA) architecture was replaced with a credential provider model, which made it possible to enumerate different logon types through the use of logon tiles. Both models are described below.

How does trusting work?

Trusts help to provide controlled access to shared resources in a resource domain (the trusting domain) by verifying that incoming authentication requests come from a trusted authority (the trusted domain). In this way, trusts act as bridges that let only validated authentication requests travel between domains.

Where are credentials stored?

Credentials are saved in special encrypted folders on the computer under the user's profile. Applications that support this feature (through the use of the Credential Manager APIs), such as web browsers and apps, can present the correct credentials to other computers and websites during the logon process.

What is DirectAccess OTP?

DirectAccess OTP authentication requires a client computer certificate to establish an SSL connection with the DirectAccess server; however, the client computer certificate was not found or is not valid, for example, if the certificate expired.

Why is OTP authentication not completed?

Does the user have permission to read the OTP logon template?

The user doesn't have permission to read the OTP logon template.

Can a client computer contact the CA that issues OTP certificates?

The user provided a valid one-time password and the DirectAccess server signed the certificate request; however, the client computer cannot contact the CA that issues OTP certificates to finish the enrollment process.

Can OTP certificates be signed on remote access?

The DirectAccess OTP signing certificate cannot be found on the Remote Access server; therefore, the user certificate request can't be signed by the Remote Access server. Either there is no signing certificate, or the signing certificate has expired and was not renewed.
