SVF Cloud and SPA Cloud services will disable Transport Layer Security (TLS) 1.0 and 1.1 cryptographic protocols in order to strengthen communication safety and security. Please review the following notice for details.
We have disabled communication encryption using TLS 1.0 and 1.1 in the affected services, as it was reported to be vulnerable. We will support communication encryption using TLS 1.2 and higher.
Environments (including programs) that do not support TLS 1.2 or higher will not be able to use the affected services after the planned maintenance dates below. When using the affected services in the future, please use communication encryption using TLS 1.2 or higher.
System maintenance was conducted on March 28, 2020.
System maintenance will be conducted on July 18, 2020.
Update about SVF Cloud Maintenance - March 30, 2020
We disabled TLS 1.0 and 1.1 in SVF Cloud through system maintenance conducted on March 21, 2020. However, in consideration of multiple customers who were unable to output forms as a result, we have decided to postpone this change.
Customers who access the service with TLS 1.0 or 1.1 may have communication vulnerabilities, such as partial leakages of communication content. Please switch to TLS 1.2 or higher by the maintenance date listed above.
The Impact on Services after TLS 1.0 and 1.1 is Disabled
- Form Output
Customers who have been using SVF Cloud Web API to output forms from programs independently developed will no longer be able to do so. After testing your program development environment, please check if you can connect to our service with TLS 1.2 or higher.
- SVF Cloud Manager and Form Layout Creation
When accessing SVF Cloud Manager, or when using the form layout creation tool started by an application installed on your device such as Excel Designer, the tool may not start depending on security settings in Windows Internet Options. Please see the FAQ for more information.
