On restart, the user is automatically signed in via the Autologon mechanism, and then the computer is additionally locked to protect the user's session. The locking is initiated through Winlogon whereas the credential management is done by LSA. By automatically signing in and locking the user's session on the console, the user's lock screen applications is restarted and available.
The credentials - part of the user's profile - are stored until needed. This action can increase security on a per-resource basis by ensuring that if one password is compromised, it does not compromise all security. After a user logs on and attempts to access additional password-protected resources, such as a share on a server, and if the user's default logon credentials are not sufficient to gain access, Stored User Names and Passwords is queried.
If alternate credentials with the correct logon information have been saved in Stored User Names and Passwords , these credentials are used to gain access. Otherwise, the user is prompted to supply new credentials, which can then be saved for reuse, either later in the logon session or during a subsequent session. If Stored User Names and Passwords contains invalid or incorrect credentials for a specific resource, access to the resource is denied, and the Stored User Names and Passwords dialog box does not appear.
Some versions of Internet Explorer maintain their own cache for basic authentication. As a result, these credentials can roam with the user if the user's network policy supports Roaming User Profiles. However, if the user has copies of Stored User Names and Passwords on two different computers and changes the credentials that are associated with the resource on one of these computers, the change is not propagated to Stored User Names and Passwords on the second computer.
Credential Manager was introduced in Windows Server R2 and Windows 7 as a Control Panel feature to store and manage user names and passwords. Credential Manager lets users store credentials relevant to other systems and websites in the secure Windows Vault. Some versions of Internet Explorer use this feature for authentication to websites. Credential management by using Credential Manager is controlled by the user on the local computer.
Users can save and store credentials from supported browsers and Windows applications to make it convenient when they need to sign in to these resources. 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.
When a website, an application, or another computer requests authentication through NTLM or the Kerberos protocol, a dialog box appears in which you select the Update Default Credentials or Save Password check box. This dialog box that lets a user save credentials locally is generated by an application that supports the Credential Manager APIs. If the user selects the Save Password check box, Credential Manager keeps track of the user's user name, password, and related information for the authentication service that is in use.
The next time the service is used, Credential Manager automatically supplies the credential that is stored in the Windows Vault. If it is not accepted, the user is prompted for the correct access information. If access is granted with the new credentials, Credential Manager overwrites the previous credential with the new one and then stores the new credential in the Windows Vault.
It is present in every Windows operating system; however, when a computer is joined to a domain, Active Directory manages domain accounts in Active Directory domains. 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. The security context of a user or computer can vary from one computer to another, such as when a user logs on to a server or a workstation other than the user's own primary workstation.
It can also vary from one session to another, such as when an administrator modifies the user's rights and permissions. In addition, the security context is usually different when a user or computer is operating on a stand-alone basis, in a network, or as part of an Active Directory domain. When a trust exists between two domains, the authentication mechanisms for each domain rely on the validity of the authentications coming from the other domain.
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. How a specific trust passes authentication requests depends on how it is configured. Trust relationships can be one-way, by providing access from the trusted domain to resources in the trusting domain, or two-way, by providing access from each domain to resources in the other domain. Trusts are also either nontransitive, in which case a trust exists only between the two trust partner domains, or transitive, in which case a trust automatically extends to any other domains that either of the partners trusts.
For information about domain and forest trust relationships regarding authentication, see Delegated Authentication and Trust Relationships. A public key infrastructure PKI is the combination of software, encryption technologies, processes, and services that enable an organization to secure its communications and business transactions. The ability of a PKI to secure communications and business transactions is based on the exchange of digital certificates between authenticated users and trusted resources.
A digital certificate is an electronic document that contains information about the entity it belongs to, the entity it was issued by, a unique serial number or some other unique identification, issuance and expiration dates, and a digital fingerprint. Authentication is the process of determining if a remote host can be trusted. To establish its trustworthiness, the remote host must provide an acceptable authentication certificate.
Remote hosts establish their trustworthiness by obtaining a certificate from a certification authority CA. The CA can, in turn, have certification from a higher authority, which creates a chain of trust. To determine whether a certificate is trustworthy, an application must determine the identity of the root CA, and then determine if it is trustworthy.
Similarly, the remote host or local computer must determine if the certificate presented by the user or application is authentic. The certificate presented by the user through the LSA and SSPI is evaluated for authenticity on the local computer for local logon, on the network, or on the domain through the certificate stores in Active Directory.
To produce a certificate, authentication data passes through hash algorithms, such as Secure Hash Algorithm 1 SHA1 , to produce a message digest. The message digest is then digitally signed by using the sender's private key to prove that the message digest was produced by the sender.
Smart card technology is an example of certificate-based authentication. Logging on to a network with a smart card provides a strong form of authentication because it uses cryptography-based identification and proof of possession when authenticating a user to a domain.
Active Directory Certificate Services AD CS provides the cryptographic-based identification through the issuance of a logon certificate for each smart card. Virtual smart card technology was introduced in Windows 8.
In this way, the PC actually becomes the smart card which must receive the user's PIN in order to be authenticated. Remote and wireless network authentication is another technology that uses certificates for authentication. For information about certificate-based authentication in networking, see Network access authentication and certificates.
