- Firewall Address: Type the IP address of the firewall.
- Port: Type the port number used by the firewall.
- Timeout: Type the appropriate time out value.
- User Name: Type the appropriate user name.
- Password: Type the appropriate password.
Note: If you selected
NVT Proxy or Firewall, then you must provide the following prompts:
- Host Name Prompt: Type the firewall prompt, or a unique
portion of the prompt, of the host name that BlueZone is expecting. For example,
Enter host name. If this prompt is detected, the Host Address
from the Connections tab is sent.
- User Name Prompt: Type the firewall prompt, or a unique
portion of the prompt, of the user name that the firewall is expecting. For example,
Enter user name. If this prompt is detected, the User Name
Prompt field is sent.
- Password Prompt: Type the firewall prompt, or a unique
portion of the prompt, of the password that the firewall is expecting. For example,
Enter password. If this prompt is detected, the Password Prompt
field is sent.
- Connected Prompt: Type the firewall prompt, or a unique
portion of the prompt, of the connection message. For example,
Connected or Connected to host. If this
prompt is detected, the firewall connection is considered to be complete and the Telnet
negotiation begins.
- In the Security tab, configure the SSL, TLS, or SSH options. BlueZone
VT can be preconfigured for distribution with encryption configured and enabled eliminating the
need for any end user intervention in the installation or configuration process.
Complete
the following fields:
- Security Options
-
- Enable Secure Sockets Layer: Specifies
whether the TCP connection to the host will be encrypted.
- Encryption Type
- SSL v3: Specifies that SSL version 3 must be used.
Note: SSL
v3 has numerous vulnerabilities and is no longer considered secure. This setting is
NOT RECOMMENDED. We strongly recommend using TLS v1 instead.
- TLS v1 (Default): Specifies that TLS version 1.0, 1.1, or 1.2
is used. The highest version supported by the client and the host will be used.
Note:
TLS v1.1 and 1.2 are not available on operating systems prior to Windows
7.
- SSH v2: Specifies that SSH version 2 must be used.
Note: When
SSH is selected, a Tunneling tab will appear at the top of this
dialog. Please refer to step 8 for information on how to configure Tunneling.
- Invalid Certificates: Specifies how to handle
an invalid server certificate. Options include:
- Always Reject: Specifies that an invalid server certificate
must always be rejected.
- Ask Before Accepting: Specifies that the user must be asked
whether to accept an invalid server certificate.
- Always Accept: (Default) Specifies that an invalid server
certificate must always be accepted.
- Check for Certificate Revocation: When checked, a revocation
check is performed on the server certificate chain at connect time, which will result
in a connection failure if a certificate has been revoked; if the revocation server
cannot be contacted; or if revocation information is not listed in the certificate.
- Preferred Cipher Suite: Specifies a specific SSL/TLS or SSH
cipher suite (encryption algorithm) to use. To allow the client and server to negotiate
the cipher suite, select Strong only.
Note: The cipher suite
choices will change depending on if you are using SSL/TLS or SSH.
Strong only is not available in SSH.
- Alternate Principal Name: Type a valid address in this field to
use to validate the server certificate.
When a host site's server
certificate's Common Name (CN) or AltSubjectName does not match the address used to
connect to the host, a certificate error occurs, stating that the host address does not
match the common name. If it is not possible to connect to the host address listed in
the certificate, the address from the certificate can be typed into the
Alternate Principal Name field. This address, rather than the
host connection address, is used to validate the server certificate.
- Remote Command: Remote Command will take the
place of Alternate Principal Name when SSH is selected. You can use this text box to send
remote commands to your SSH connected host. This feature is popular with Linux hosts.
- In the Certificate tab, complete the following fields:
- Client Certificate
- These parameters specify the type of client certificate to use if any. Enable
Secure Sockets Layer on the Security tab must be enabled
in order for client certificate support to be active.
- No Client Certificate: Specifies that a client certificate must
not be presented.
- Client Certificate in Disk File: Specifies that a client
certificate must be presented.
- Client Certificate in Certificate Store: Specifies that a client
certificate must be presented that is located in the certificate store.
-
Client Certificate in Certificate on Smart Card: Specifies that a
client certificate stored on a Smart Card must be presented.
- Certificate File: Specifies the path to the certificate file.
- View: Click to view the certificate.
- Browse: Click to locate the certificate file.
- Private Key File: Specifies the path to the private key
file.
- Browse: Click to locate the private key file.
- Root Certificates
- These parameters specify the root certificate store to use: the one provided by OpenSSL,
or the one that is provided by Windows.
- Use OpenSSL Root Certificates: (Default) If selected, the root
certificates provided by OpenSSL is used.
- Use Windows Root Certificates: If selected, BlueZone looks for a
file called rootcerts.pem in the end user's
bluezone\certs directory. If it doesn't exist, it automatically
exports the root certificates from Windows and stores them there, giving a message such as
109 root certificates were exported.
- Update Root Certificates: Click to manually export the
certificates. If you connect and are presented with an untrusted host root certificate,
and check the box to add it to the trusted list, it imports it into the Windows root
store (which can produce a Windows message asking for confirmation), and then exports
the root store again to disk producing a message such as 109 root
certificates were exported. When this is performed one time, subsequent
connections connect without messages.
- In the Kerberos tab, you can configure the optional Kerberos
Authentication Protocol component. If the Kerberos tab is not available,
the Kerberos component was not installed. Refer to the BlueZone Desktop Administrator's
Guide in Chapter 2: Installing BlueZone - Optional installation features - Enabling
Kerberos for information about installing the Kerberos Authentication feature.
Complete the
following fields:
- Kerberos options
-
- Enable Kerberos Authentication: To enable Kerberos
Authentication for this session, place a check in this check box.
- Use Windows Credentials: If enabled, your Windows
credentials (User Name and Domain) are used in lieu of Principal and Realm. Your User
Name is used as the Principal name and your Domain name is used as the Realm name.
- Forward Credentials: If enabled, your credentials are forwarded
to the remote session. The credentials are passed as a Kerberos message which includes,
among other things, the forwarded Kerberos ticket and a session key associated with the
ticket.
- Principal: If you are not using your Windows credentials,
type your Principal name here.
- Realm: If you are not using your Windows credentials, type the
Realm name here. The Realm name must be typed entirely in uppercase.
- Target: Type the name of the Kerberos database.
- Manage Tickets: Click to manage Kerberos tickets. The Kerberos
Ticket Manager opens.
- The Tunneling tab will only appear when SSH is selected on the
Security tab.
Complete the following fields:
- Tunneling Options
-
- Allow Remote Connections: If enabled, you are allowing remote IP
addresses to connect to the local listening port used in tunneling.
- Add, Edit or Delete: Used to add, edit or delete port forwarding
rules.
- Add: When adding a rule, you have to choose either
Local Port or Remote Port, then enter the
port number you want to forward. Then you have to add the host name in the
Name field with the port number on that host.
- Edit: Allows you edit an existing rule.
- Delete: Allows you delete an existing rule.
- Click OK.
Note: If you enable the Direct/Modem feature in the global.ini file, you can change the
connection type from Telnet to Direct or
Modem using the Connection Type list that appears
in the Connection tab. If you select either Direct
or Modem connections, you will have the option to select your desired
Baud Rate, Data Bits,
Parity, Stop Bits, Flow
Control, and Phone Number (modem only). For more information
on enabling the Direct/Modem feature, refer to the Rocket BlueZone Desktop Adminitrator's
Guide.
