Disable SSL 3.0 and TLS 1.0 on Forefront TMG and UAG 2010

December 27, 2016 Comments off

When performing SSL and TLS hardening on Microsoft Forefront Threat Management Gateway (TMG) 2010 or Forefront Unified Access Gateway (UAG) 2010 servers, disabling SSL 3.0 and TLS 1.0 is often required to meet regulatory and compliance guidelines for security. However, disabling SSL 3.0 and TLS 1.0 causes the SQL Server (ISARS) and SQL Server Express services to fail on start up.

Switching from SQL logging to text file logging can be employed as a workaround. However, when using text file logging, generating historical reports in the TMG management console is no longer supported.

To restore full functionality for SQL logging and reporting when SSL 3.0 and TLS 1.0 are both disabled, an update to the local security policy of the server is required. Open the Local Security Policy editor by clicking on the Start button and navigating to Administrative Tools and Local Security Policy. Expand Local Policies and click on Security Options. Double-click on System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing. Click Enabled and then click OK.

Restart the computer for the changes to take effect. Once complete, all SQL services should start and run without issue.

Note: If Remote Desktop Services (RDS) is used to manage the Forefront TMG firewall it will be necessary to install update KB3080079.


 

Using PowerShell to Determine Forefront TMG Build Number

December 14, 2015 Comments off

Using PowerShell to Determine Forefront TMG Build NumberIdentifying the current build number of your Forefront TMG 2010 installation is critically important when making changes or updates to the system. It is generally recommended that all TMG firewalls be on the same release, so having this information is essential. Many TMG administrators use the TMG management console to gather this information, but I can tell you based on experience that this is not always the most accurate method to use.

I much prefer to gather this information programmatically at the command line. In the past I’ve written about using VBScript to do this, but it’s almost 2016 now and we really should be using PowerShell whenever possible. To that end, here are a few lines of PowerShell code you can use to accurately determine which version and build number your TMG firewall is currently running.

$FPC = New-Object -ComObject FPC.Root
$Server = $FPC.GetContainingServer()
$Server.ProductVersion

Using PowerShell to Determine Forefront TMG Build Number

If you’ve done any work at all with VBScript and the TMG’s FPC COM object, you’ll no doubt be able to convert some of your existing scripts to PowerShell. Also, PowerShell, with its tab auto completion, is much more discoverable than using VBScript with COM, so I’m sure you’ll be able to do a lot more with TMG using PowerShell.

Enjoy!

Forefront TMG 2010 End of Life Statement

September 12, 2012 54 comments

Note: This post updated on 4/22/2015 to reflect current information about the status of the Microsoft Reputation Service (MRS) after December 1, 2015.

Today, Microsoft announced the Forefront TMG 2010 product will be discontinued. Microsoft will continue to provide mainstream support for TMG until April 14, 2015, and extended support until April 14, 2020. The Forefront TMG 2010 Web Protection Services (WPS) will be discontinued on December 31, 2015. Beginning on January 1, 2016, Web Protection Service (URL filtering) will cease to function and the Microsoft Reputation Service (MRS) will be shutdown permanently. Virus and malicious software scanning and the Network Inspection System (NIS) will continue to operate but will no longer receive updates.

The end of life for Forefront TMG 2010 comes as part of sweeping changes made to the entire Forefront protection suite of products. In addition to ending development of Forefront TMG 2010, Microsoft also announced that Forefront Protection for Exchange (FPE), Forefront Protection for SharePoint (FPSP), Forefront Security for OCS (FSOCS), and Forefront Protection Server Management Console (FPSMC) are all being discontinued. Forefront Online Protection for Exchange (FOPE), which has been a part of Office 365, is being renamed Exchange Online Protection.

Looking ahead, Forefront Unified Access Gateway (UAG) 2010 and Forefront Identify Manager (FIM) 2010 R2 both have current roadmaps and will continue to be developed, although it is likely that they will not continue under the Forefront brand name.

Forefront TMG 2010 Update Center Quick Tip

July 10, 2012 Comments off

The Update Center in the Forefront TMG 2010 management console provides an instant view of the status of signature updates for the Malware Inspection and Network Inspection System (NIS) protection mechanisms. However, the column layout leaves out important information that can be essential when troubleshooting signature update issues. By default, the Last Checked and Last Success columns are hidden from view. To display these details, right-click anywhere in the column headings and then select Add/Remove Columns.

Next, select the Last Checked and Last Success columns and click Add.

Now you’ll see when the Forefront TMG 2010 firewall last checked for updates and when it was last successful.
