3.4 Secure Connections

This section describes the principles of establishing secure connections to SQL Server using

ODBC Driver for SQL Server.

SSL Connection Description

SSH Connection Description

HTTP Tunneling Description

3.4.1 SSL Connection Description

SSL (Secure Sockets Layer) is the protocol for secure access to remote computers over

insecure communication channels.

The SSL protocol runs above TCP/IP and below higher-level database protocol. It uses TCP/

IP on behalf of the higher-level protocols, and in the process allows an SSL-enabled server to


© 2018 Devart

authenticate itself to an SSL-enabled client, allows the client to authenticate itself to the

server, and allows both machines to establish an encrypted connection.

These capabilities address fundamental concerns about communication over the Internet and

other TCP/IP networks:

SSL server authentication allows a user to confirm a server's identity. SSL-enabled client

software can use standard techniques of public-key cryptography to check that a server's

certificate and public ID are valid and have been issued by a certificate authority (CA) listed

in the client's list of trusted CAs. This confirmation might be important if the user, for

example, is sending a credit card number over the network and wants to check the

receiving server's identity.

SSL client authentication allows a server to confirm a user's identity. Using the same

techniques as those used for server authentication, SSL-enabled server software can

check that a client's certificate and public ID are valid and have been issued by a certificate

authority (CA) listed in the server's list of trusted CAs. This confirmation might be important

if the server, for example, is a bank sending confidential financial information to a customer

and wants to check the recipient's identity.

An encrypted SSL connection requires all information sent between a client and a server to

be encrypted by the sending software and decrypted by the receiving software, thus

providing a high degree of confidentiality. Confidentiality is important for both parties to any

private transaction. In addition, all data sent over an encrypted SSL connection is protected

with a mechanism for detecting tampering--that is, for automatically determining whether

the data has been altered in transit.

SSL is based on algorithms of asymmetric encryption and digital signature. Consult SQL

Server Reference Manual for information about How to enable SSL encryption for an instance

of SQL Server by using Microsoft Management Console .

Note:

Usage of SSL is more preferable for SQL Server connections than SSH because of less

required settings and higher performance.

How to connect to SQL Server using SSLTo use SSL encryption for connection to SQL Server, enable the Use Encryption for Data

option.

3.4.2 SSH Connection Description

ODBC Driver for SQL Server allows connection to SQL Server server from a local computer

using SSH tunneling.

SSH (Secure Shell) is the protocol for secure access to remote computers over insecure

communication channels.

The general chart of computer ties when connecting through the SSH tunnel is presented

below:


© 2018 Devart

This connection method provides secure connection between your application using ODBC

Driver for SQL Server and SSH server that can go through insecure communication

channels, like Internet.

Connections between DB server and SSH server are insecure, therefore they should go

through secure communication channels. In the confluent case, DB server and SSH server

can be located on the same computer.

The principle of working of the SSH connections is described below. The SSH server listens

to the specified TCP/IP port. When the client tries to connect to this port, the SSH server

authenticates the client. If the authentication passes, the connection is established. Then the

client should create connections to DB server objects. The client sends an inquiry to establish

necessary connection to SSH server, and the server establishes it.

SSH Configuration using OpenSSH or other third-partySSH tunnelThe following is the step-by-step sequence of actions for the easiest case of using OpenSSH

for Windows. The detailed description of each command you can see in the documentation

for OpenSSH.

1. Download OpenSSH for Windows from http://sourceforge.net/projects/sshwindows/

2. Install SSH server:

o Choose a machine that will be used as SSH server. It does not have to be the same

machine that is a SQL Server server, but communication channel between SSH server

and SQL Server server must be protected

o Using Windows Control Panel create a user and set a password for him. For example,

SSHUser with password SSHPass

o Install Open SSH. It is enough to install only Server components

o Open OpenSSH/bin folder

o Add SSHUser to the list of allowed users:

mkpasswd -l -u SSHUser >> ..\etc\passwd

o Use mkgroup to create a group permissions file

http://sourceforge.net/projects/sshwindows/

mkgroup -l >> ..\etc\group

o Run OpenSSH service

net start opensshd

Note:

There is no need to install SSH client, since ODBC Driver for SQL Server itself implements

SSH client functionality.

About the methods of higher protection (key authentication, etc.) see documentation for

OpenSSH.

How to establish SSH connection to SQL ServerTo establish a SSH connection to SQL Server, the corresponding connection options have to

be set, like shown below:

Using ODBC Data Source Administrator:

SSH Options Description:


© 2018 Devart

Option Description

Use SSH Enables or disables SSH tunneling.

SSH Host nameHolds the host name or IP address of the

SSH server to connect to.

SSH PortUsed to specify the port number for SSH

connection.

SSH User Name Sets the SSH user name for authentication.

SSH PasswordSets the SSH user password for

authentication.

SSH Client Key

Used to specify the path to the file

containing the SSH Private Key.

If the authentication by key is used, the user

must have his pair of keys. The public key

should be transferred to the server, while

the private key will be used by the client to

sign data,

that will be used by server to authenticate

the user. The server verifies the specified

user name and Private Key - and if the

Server Key corresponds to this user,

connection may be established.

SSH Server KeyUsed to specify the path to the file that

contains SSH Public Key.

SSH StoragePathUsed to specify the path to the directory

where encyption keys are stored.

Example Connection String:

User ID=sa;Data Source=DBMSSQL;Port=1433;Use SSH=true;SSH

Hostname=localhost;SSH Port=22;SSH Username=SSHUser;SSH

Password=SSHPass;SSH Client Key='C:\User\...\PrivateKey.pem';SSH

Server Key='C:\User\...\PublicKey.pem';SSH StoragePath='D:\...';

3.4.3 HTTP Tunneling Description

Connection through HTTP tunnelSometimes client machines are shielded by a firewall that does not allow you to connect to

server directly at the specified port. If the firewall allows HTTP connections, you can use

HTTP tunneling based on the PHP script.

An example of the web script tunneling usage can be the following: you have a remote

website, and access to its database through the port of the database server is forbidden. Only

access through HTTP port 80 is allowed, and you need to access the database from a

remote computer, like when using usual direct connection.

To start using HTTP tunneling, you should deploy the Tunneling script. The php script must

be available through the HTTP protocol. You can verify it is accessible for a web. For this

enter the http://www.domain.com/tunnel.php address to a web browser and check the result.

The only requirement to the server is PHP 5 support.

P.S.: tunnel.php is provided along with ODBC Driver for SQL Server. It is available at the

driver installation path, in the http folder, by default: C:\Program Files (x86)\Devart\ODBC\SQL

Server\http\tunnel.php

To connect to the database, you should set connection parameters for usual direct

connection and set the following parameters specific for the HTTP tunneling:

Using ODBC Data Source Administrator

HTTP Options Description

Option Description

Use Http Enables or disables HTTP tunneling.

Http Url Holds the url of the tunneling PHP script.

Http UsernameSet these properties if the access to the

website folder with the script is available

only for registered users authenticated with

user name and password.Http Password


User ID=sa;Data Source=192.168.0.10;Port=1433;Use

Http=true;Url=http://server/tunnel.php;Http Username=HttpUser;Http

Password=HttpPassword;

Connection through proxy and HTTP tunnelConsider the previous case with one more complication.


© 2018 Devart

HTTP tunneling server is not directly accessible from client machine. For example, the client

can reach the server only through proxy at address 10.0.0.1, which listens on port 3128. In

this case in addition to the HTTP options, you have to setup Proxy options as follows:

Proxy Options Description

Option Description

Proxy Host NameHolds the host name or IP address of the

proxy server to connect to.

Proxy PortUsed to specify the port number for TCP/IP

connection with proxy server.

Proxy Username Holds the proxy server account name.

Proxy PasswordHolds the password for the proxy server

account.


User ID=sa;Data Source=192.168.0.10;Port=1433;Use

Http=true;Url=http://server/tunnel.php;Proxy

Hostname=10.0.0.1;Proxy Port=3128;Proxy User=ProxyUser;Proxy


© 2018 Devart

Password=ProxyPassword;

Additional informationTechnically speaking, there is one more way to tunnel network traffic. The Secure Shell

forwarding, or SSH, can be used for forwarding data. However, main purpose of SSH is traffic

encryption rather than avoiding firewalls or network configuration problems. The SSH

Connection article describes how to use SSH protocol in ODBC Driver for SQL Server.

Keep in mind that traffic tunneling or encryption always increase CPU usage and network

load. It is recommended that you use direct connection whenever possible.
