Deprecation of Windows SQL 2008 R2
Before upgrading to Trust Protection Platform 17.4, you must make sure that the Microsoft SQL Server hosting the Trust Protection Platform database is running Microsoft SQL Server 2012 SP2, 2014, or 2016 with the latest patches applied.
For more information, see Error: "This Upgrade Is Not Allowed Due To An Incompatible Version Of SQL Server"
Oracle Access Manager/SSO Authentication Refactor
Oracle Access Manager integration, where Trust Protection Platform is configured to authenticate via custom header attributes, has been refactored in 17.4 and renamed Pass-through Authentication. If you are integrating with Oracle Access Manager, Siteminder, or any other Single-Sign-On solution that integrates via custom HTTP headers, you will need to update your configuration before the integration will work on 17.4.
For more information, see: Pass-Through Authentication For SSO Updated In 17.4
DigiCert CA Platform Support
The DigiCert integration driver was updated in 17.3 to support CertCentral. It no longer supports the legacy Enterprise platform. If you are currently using the Enterprise platform, please coordinate with DigiCert to migrate to the new CertCentral platform before upgrading to 17.4.
DataPower Integration Support
The DataPower integration driver was updated in 17.3 to support the new REST interface available on newer versions of DataPower. If you are using older versions that support the legacy SSH Command Line Interface (CLI), consider upgrading so that you can take advantage of new functionality in the integration. Legacy versions using SSH CLI are expected to continue to work, but are no longer actively tested.
Venafi License Report
Beginning with Trust Protection Platform 17.3, the Venafi License Report is automatically sent to Venafi.
For more information, see Info: License Report Changes FAQ For 17.3
Update to Groups and Work
Beginning with Trust Protection Platform 17.2, the functionality for managing Server Agents, SSH Discovery/Remediation, User Portal, and Enterprise Mobility Agent changed significantly. If you are not yet familiar with these changes, or if you are planning to upgrade to version 17.2 or later, carefully review 17.2 Updates to Groups and Work to learn about the new functionality, why the changes were made, and specific tasks to consider following the upgrade.
SSH Key Internal Storage Migration
When upgrading from Trust Protection Platform 17.1 (or earlier), all SSH keys in the database are migrated to an updated storage format. When the Venafi Control Center (VCC) is executed, it might take more time than normal for the migration to complete. In Venafi's internal testing, the migration was able to process approximately 5,800 SSH keys every minute. For 100,000 keys, it might take about 20 minutes to run. The actual processing rate could vary depending upon version of SQL Server you're running, latency between Trust Protection Platform and the database server, database disk speed, CPU/RAM of the SQL Server, and other loads on the server that might be running during the same time period. Progress is displayed in Venafi Control Center.
During upgrade, you might see the following message in Trust Protection Platform logs:
"SSHManager - Erroneous Key Instance" - "Key at <path> removed from database because it did not have secret store association. You may need to re-discover this key."
This message indicates that your Trust Protection Platform instance was impacted by the following bug (#33848):
If the same private key was discovered on two devices and the first device was subsequently deleted, the private key was then placed into an orphaned state by TPP and became non-operational.
This bug has been addressed so that the issue will not occur again. The migration script returns the database back to a consistent state by removing the affected private key entries. The affected private keys must then be rediscovered. With agentless discovery, this will happen automatically during the next discovery. With agent-based discovery, you will need to flush the agent’s SSH key cache and re-discover keys on corresponding devices.
Symantec MPKI Enrollment Mode
In previous versions, the certificate that was renewed with the Symantec MPKI driver supported a per-certificate enrollment mode option with which you could control whether your renewal request was treated as a new, renewed, or replacement certificate.
As of TPP 17.2 (or later), this feature has been migrated to settings on the Symantec certificate authority (CA) template in the Web Administration Console. Instead of managing the enrollment logic on a certificate-by-certificate basis, the logic is now automatic and configured for all certificates being enrolled via that CA template.
Oracle Database Server No Longer Supported
WARNING! If your Trust Protection Platform database is currently being hosted on Oracle, do NOT attempt to upgrade to 17.4. You must first migrate your production database from Oracle to Microsoft SQL Server. Contact Venafi Customer Support for assistance with the migration.
Change in Requirements for Database Service Account Permissions
Enhancements made in 15.1, 15.3, 16.2, and 17.1 have changed the permissions required by the Microsoft SQL Service account used to connect Trust Protection Platform to the database. Refer to the sample grant scripts (ex: sample_grants_16.4_to_17.1.sql) in the Database Scripts\MSSQL\Updates folder for sample scripts to learn how to modify the permissions for your database.
Consult with your database administrator (DBA) before changing permissions for the database.
DSA SSH Credentials for SSH Connections
Trust Protection Platform 17.2 and 17.1.2 have a new version of Venafi's Maverick library that is used as an SSH client by Trust Protection Platform to communicate with remote systems. If you want to discover DSA keys or use DSA keys for authentication to remote systems, then do the following:
- In the Windows Control Panel, navigate to the Network Connections, Advanced settings. Disable the setting for Federal Information Processing Support (FIPS) compliance for this network.
- On the Trust Protection Platform server running Discovery, add the following registry key: HKLM\Software\Venafi\Platform\EnableSSHDSS (string key), value: 1.
License and Usage Statistics Collected
New in Trust Protection Platform 17.1, high level statistics and license usage can optionally be collected and emailed to Venafi at firstname.lastname@example.org. No sensitive or personally identifiable data, such as IP and email addresses, host names, or user names, is being sent. Please ensure that the email account used to email other reports has access to email outside recipients.
For more information about the benefits and frequently asked questions about this feature, see Licensing Report FAQ on the Venafi Documentation Portal.
Aperture Certificate Status Updated
Certificate Inventory Status column is divided into two columns: Risks and Status. The Status column contains a single life-cycle stage, such as "Renewing" or "Pending My Approval". The Risks column can contain one or more tags, such as "Unapproved Issuer" and/or "No Local Dual Control". Certificate Overview Banner has been updated to show "Status" information only (not Risk). If you have custom reports that were reporting on Status and wish for them to continue to report on certificate risk information, you will need to update the report to include the new column.
Encrypted Connection to Microsoft SQL
Trust Protection Platform can now require a secure, encrypted connection to the database. To enable this option, open Venafi Control Center on each Trust Protection Platform server, click Change Database Password, select Encrypt all database communications, and click the Verify button. This security feature requires a valid TLS certificate on the Microsoft SQL Server. You may have to install/replace the certificate on your SQL server prior to enabling this functionality on each Trust Protection Platform server.
Potentially Longer Upgrade Window for Migrating Logs
Significant refactoring was done to the TPP logging system in 16.2, affecting how logs are stored in the database. When the mssql_update_16.1_to_16.2.sql upgrade scripts are executed, the format of the data is modified. For every 30 million rows in the logs, you can expect the script to take approximately an hour (subject to hardware, SQL Server version, server utilization, and other factors).
It is recommended, if possible, that you archive or reduce the number of logs stored in the Trust Protection Platform database prior to upgrading to 17.4 from 16.1.x or older.
If you have secondary log tables, read this KB article to learn how to migrate them: https://support.venafi.com/hc/en-us/articles/220761368.
Update of Universal C Runtime is Now Required
Starting in version 16.3, TPP requires an update of the Universal C Runtime in Windows in order to provide SNI (Server Name Indication) support for SSL/TLS validation of certificates. This update must be installed before you run the 16.4 Trust Protection Platform or later installers. This is required on both Windows 2008 R2 and Windows 2012 R2.
Download the update specific to your OS version at: https://support.microsoft.com/en-us/kb/2999226
Trust Protection Platform 16.4 Requires .NET Framework 4.6.1
Before upgrading to TPP 17.4 from 16.3 or lower, make sure the .NET Framework is updated to 4.6.1.
You can download the offline .NET 4.6.1 installer for Windows 2012 R2 at:
Note: Windows Server 2016 comes pre-installed with .NET 4.6.2
Web Admin Console Policy Tree Performance Improvement
The Policy Tree in the TPP 16.4 Web Admin console has been refactored to provide significantly faster load times. One behavior difference you will notice is that all nodes of the tree will have a + (plus) sign for the expansion of child nodes. This sign is displayed for all objects. If a node does not have any child objects, the + sign will disappear after it's clicked.
Privileged Command Set Change for SSH Agentless
In 16.4 the list of commands that the SSH discovery and remediation engine runs with sudo privileges has changed. Some commands are no longer required in order to run as a privileged user and some new commands are required. Refer to this article for detailed instructions on restricting commands in sudoers to only those required for the agentless SSH account.
The following commands are no longer required and can be removed from /etc/sudoers entry:
- sh –c find *
The following new commands need to be present in /etc/sudoers entry:
For more information, see: Restricting Account To Use With Agentless SSH
Updated SSH Folder Policy Violation Settings in Aperture
When configuring SSH folder policy violation settings in Aperture, the functionality has been modified for consistency and clarity. For example, in previous versions, one setting was called “Allow Root Access.” This setting has been renamed “Flag Root Access” so it is clear that items will still be permitted, but they will be flagged with a status tag that allows you to find them easily.
If you are upgrading to version 16.3, your folders will be updated automatically. The underlying behavior won’t change. So, if items were being given status messages in older versions, they will continue to be given status messages in 16.3. The labels are now clearer about what is occurring when these settings are being configured.
Password Complexity Requirements are Increased and "on" by Default
The updated requirements are:
- At least 12 characters long
- Must contain a combination of at least three out of the following four categories: uppercase alphabetic, lowercase alphabetic, numeric, and special characters
These changes apply to:
- Downloading certificates that contain private keys from the Web Admin console or Aperture.
- Retrieving certificates that contain private keys from WebSDK
- New local to Trust Protection Platform accounts (or when passwords are changed for existing accounts)
Note: The complexity requirements listed above do not apply to the automated installation of certificates via Provisioning drivers. These are typically governed by password credential objects via permissions and policy.
As before, Master Admins (or those with appropriate delegated permissions) can turn complexity requirements off for certificate private key download via policy.
Database Log Retention must be Specified on Upgrade
The database log retention feature introduced in 16.2 can now be configured in the Venafi Control Center (VCC) wizard during the upgrade and installation process. If this value is left blank when upgrading from 16.1 or older, then your installation will NOT delete any logs and your logs will continue to grow. It is recommended that a value be entered in VCC (for example, 365 days) on the first TPP server that is upgraded to 16.4, which will apply for all servers.
MD5 to SHA-256 Host Key Conversion
As part of the SSH-based agentless connections that enable certificate provisioning/validation and SSH key discovery/management, TPP provides the ability to manage and configure trust of SSH host keys. Beginning in 17.1, trusted SSH host keys are stored using SHA-256 instead of MD5. Following an upgrade to 17.1 or later, this change may impact host key trust during the first connection on each device object where you are enforcing host key trust. If you are enforcing host key trust on device objects in TPP for SSH agentless connections, please read the following KB article: MD5 to SHA-256 Host Key Conversion.
