Does CIFS use Kerberos?

Does CIFS use Kerberos?

The CIFS server supports two authentication methods, Kerberos and NTLM (NTLMv1 or NTLMv2). Kerberos is the default method used to authenticate domain users.

How do I check my Kerberos tickets?

To view or delete Kerberos tickets you can use the Kerberos List (Klist.exe). The Klist.exe is a command-line tool you can find in the Kerberos resource kit. You can only use it to check and delete tickets from the current logon session. We recommend destroying your Kerberos tickets after your use.

What is included in Kerberos ticket?

In a Kerberos environment, the authentication server logically separated into three parts: A database (db), the Authentication Server (AS), and the Ticket Granting Server (TGS). These three parts, in turn, exist in a single server called the Key Distribution Center. Ticket Granting Server (TGS).

How does CIFS authentication work?

Authentication is the process of verifying the identity of an entity. The CIFS server supports two authentication methods, Kerberos and NTLM (NTLMv1 or NTLMv2). Kerberos is the default method used to authenticate domain users.

How do I test Kerberos authentication?

You can view the list of active Kerberos tickets to see if there is one for the service of interest, e.g. by running klist.exe. There’s also a way to log Kerberos events if you hack the registry. You should really be auditing logon events, whether the computer is a server or workstation.

How do Kerberos tickets work?

Under Kerberos, a client (generally either a user or a service) sends a request for a ticket to the Key Distribution Center (KDC). The KDC creates a ticket-granting ticket (TGT) for the client, encrypts it using the client’s password as the key, and sends the encrypted TGT back to the client.

How do I know my CIFS?

How to Find Available CIFS Shares on a Known File Server

1. Determine the server that you want to query about available shares.
2. List the available CIFS shares on a server.
3. When prompted, enter the password for the user that you specified on the CIFS server.
4. View the list of available CIFS shares.

How to Mount windows CIFS share using Kerberos?

In this post I will describe how to mount a Windows CIFS share from a Linux system using Kerberos authentication to a Windows Active Directory domain. In addition, the users credentials will be stored securely in a keytab file. Step 2. Run kdestroy to clear the Kerberos cache Step 3.

How are attackers use Kerberos silver tickets to exploit?

In normal Kerberos operations, the authentication ticket (TGT) is used to request service tickets (TGS) for each Kerberos enabled service. Silver Tickets bypass this normal process by injecting the forged Kerberos TGS tickets directly. Multiple Silver Tickets may be required to access the target service (s).

Why is the Kerberos service principal name on the wrong account?

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/machinename.childdomain.rootdomain.com. The target name used was cifs/machinename.domain.com. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server.
