The following sections describe configuration settings available only for the MSSQL protocol. Use the following policies to control who, when, and how can access the MSSQL connection. For a list of supported client applications, see Supported protocols and client applications.
Channel Policy: The MSSQL protocol has only one channel type with no special configuration options. The available channel policy options are the following: Type, From, Target, Time policy, Four-eyes, Record audit trail, Gateway groups, Remote groups, and Content policy. For details on configuring these options, see Creating and editing channel policies.
TLS support: To enable TLS-encryption for your MSSQL connections, see Enabling TLS-encryption for MSSQL connections.
Authentication Policy: Authentication policies describe the authentication methods allowed in a connection. Different methods can be used for the client and server-side connections. For details, see Creating a new MSSQL authentication policy.
MSSQL settings: MSSQL settings determine the parameters of the connection on the protocol level, including timeout value, and so on. For details, see Creating and editing protocol-level MSSQL settings.
User lists in Channel Policies: User lists affect MSSQL connections only when they are used together with Gateway Authentication. For details, see Configuring gateway authentication.
Content Policy: Content policies allow you to inspect the content of the connections for various text patterns, and perform an action if the pattern is found. For example, One Identity Safeguard for Privileged Sessions (SPS) can send an e-mail alert if a specific command is used in a MSSQL terminal session. For details, see Creating a new content policy.
Authentication and Authorization plugin:
One Identity Safeguard for Privileged Sessions (SPS) provides a plugin framework to integrate SPS to external systems to authenticate or authorize the user before authenticating on the target server. Such plugins can also be used to request additional information from the users, for example, to perform multi-factor authentication.
For details, see Integrating external authentication and authorization systems.
This section focuses on describing the MSSQL-specific details of connection configuration. For a detailed description on configuring connections, see General connection settings.
The current version of One Identity Safeguard for Privileged Sessions (SPS) has the following limitations:
MSSQL server with TCP dynamic port settings is not supported.
You must specify a static TCP port for every instance in the SQL Server Configuration Manager you want to audit. By doing so, you can configure the access to multiple MSSQL instances with multiple connection policies and specify the instances with inband or fixed targets and ports. You can also create and assign different Credential Store policies to check out SQL users' passwords of the instances.
In the MSSQL client program, always specify the address with the port number of the SPS connection policy you want to connect to.
The available MSSQL channel types and their functionalities are described below. For details on configuring Channel Policies, see Creating and editing channel policies. For a list of supported client applications, see Supported protocols and client applications.
MSSQL: Enables you to use the MSSQL protocol. This channel must be enabled for MSSQL to work.
The available channel policy options are the following: From, Target, Time policy, Four-eyes, Record audit trail, Gateway groups, Remote groups, and Content policy. Note that the Gateway groups option is used only if the user performs inband authentication using one of the supported MSSQL authentication methods (see Authentication in MSSQL). To retrieve the groups of an authenticated user from an LDAP database, you must also set an LDAP Server in the Connection Policy (for MSSQL connections, One Identity Safeguard for Privileged Sessions (SPS) uses this server only to retrieve the group membership of authenticated users, you cannot authenticate the users to LDAP from SPS). For details on configuring these options, see Creating and editing channel policies.
When setting Target, note the following:
If the connection uses DNAT (NAT destination address), the target address of the original client will be compared to the Target parameter of the Channel policy, that is not necessarily equivalent with the server's address.
If the connection is redirected to a Fix address, the redirected address will be compared to the Target parameter of the Channel policy.
