Security Considerations for Legacy Drivers
Using the SQL Server Native Client 10.0 ODBC driver in 2025 comes with serious security implications:
- End of Support: Microsoft ended mainstream support for SQL Server 2008 in 2014, and extended support ended in 2019. No security patches are issued for this driver.
- TLS Limitations: As mentioned, TLS 1.2 support is incomplete. This exposes connections to downgrade attacks.
- Mitigations:
- Run the driver only on isolated network segments with strict firewall rules.
- Use Windows Firewall to restrict which applications can use the driver.
- Encrypt data at the application level if possible.
- Plan a migration path away from the dependency on Native Client 10.0.
Step 4: Choose Installation Type
Typically, select Typical installation. This installs all components (both ODBC driver and OLE DB provider).
