What's New in this Release
This section describes the new features and enhancements in this release of AsyncOS for Secure Email and Web Manager.
Feature |
Description |
||||||
---|---|---|---|---|---|---|---|
[On-premises only] FIPS Certification |
Cisco Secure Email and Web Manager is FIPS certified and has integrated the following FIPS 140-2 approved cryptographic module: Cisco Common Crypto Module (FIPS 140-2 Cert. #4036).
For more information, see FIPS Management. |
||||||
Single Log Line (SLL) |
The SLL feature creates, indexes, and stores the email tracking data as a single log line or a flattened model. Therefore, you can execute a query and get a response quickly. This feature boosts the tracking query or search performance through fast response, low memory, and CPU usage. This feature is only applicable to post-upgrade email tracking data. |
||||||
Configuring CRL Sources |
The Secure Email and Web Manager checks a list of revoked certificates called a Certificate Revocation List (CRL) as part of its certificate verification to ensure that the user’s certificate has not been revoked. You need to keep an up-to-date version of this list on a server, and the Secure Email and Web Manager downloads it on a schedule you create. You can manually update the list too. You can configure CRL sources using the following ways:
For more information on Configuring CRL Sources, see Configuring CRL Sources. |
||||||
Removal of Old Splunk Data |
When you upgrade to Secure Email and Web Manager 15.0 and later, and if email tracking data is contained in the Splunk database, the system will delete the Splunk database and binaries if you proceed with the upgrade.
During the upgrade to Secure Email and Web Manager 15.0 and later, a warning message indicating that the system will delete the Splunk database is displayed in the CLI or on the web interface of your Secure Email and Web Manager. Sample Warning Message "From the Secure Email and Web Manager 13.6.2 version onwards, we have moved to a newer storage system for email tracking data. Generally, the old data is replaced with new data in the new storage system automatically. However, in some scenarios (for example, late upgrades, low mail flow and tracking data, and so on), there could be traces of old data still present in the old storage system that is no longer supported. In your case, it is 19 MB, which was last updated on 11 Aug 2022. You can take a back up of the email tracking data (if required). You can use the backupconfig command in the CLI to perform the backup action. For more information, see the 'Scheduling Single or Recurring Backups' section in the 'Common Administrative Tasks' chapter of the user guide. If you proceed with this upgrade process, your Splunk email tracking data will be deleted. You can choose to proceed with the upgrade or abort the upgrade. Do you agree to proceed with this upgrade? [Y]"
