Purpose: To enhance security, we will be removing support for some TLS 1.2 cipher suites and removing the ability to embed ImageSilo in third party sites.

Customer Impact:
No impact is expected for the vast majority of customers. A small number of customers identified as using the affected TLS 1.2 ciphers have already been notified. Any third-party websites embedding ImageSilo via an iFrame will no longer function as expected.

Details:
ImageSilo Engineering will update our network infrastructure to phase out AES (Advanced Encryption Standard) CBC (Cipher Block Chaining) based encryption in TLS 1.2 in favor of AES GSM (Galois/Counter Mode) in TLS 1.2 and the TLS 1.3 cipher group. It’s important to note that AES-CBC based encryption is secure and widely regarded as robust against cryptographic attacks. However, omitting the AES-CBC encryption enhances security, improves performance, and helps to defend against potential emerging threats.

If you wish to confirm that your systems will remain compatible with the post maintenance cipher suites, we have enabled a test endpoint that simulates the upcoming change to TLS 1.2:

https://tls.imagesilo.com

This endpoint serves the same data as ImageSilo but excludes the AES-CBC based ciphers. If you can connect to it successfully, your systems are compatible. This endpoint is intended for short-term testing only and is not guaranteed to remain available in the future. If you are unable to connect or encounter any issues, please contact ImageSilo Administration for assistance.

In addition, ImageSilo Engineering will be disabling third party embedding of ImageSilo (iFrame support) by enforcing modern content security controls. This change aligns with industry best practices to help prevent spoofing and clickjacking risks. Note that this change will not impact ImageSilo E-Forms hosted on third party sites, as the update has been designed to allow E-Forms to continue using iFrames.

These changes are part of our ongoing efforts to maintain the highest standards for data integrity, security, and availability.

Please note that these dates are subject to change. If changes occur, another ImageSilo Maintenance Notification will be sent to you. As always, we greatly appreciate your business.

Please feel free to contact ImageSilo Administration with any questions or comments.
