Why does Business Central still support RSA-CBC ciphers (TLS_ECDHE_RSA_with AES_128_CBC_SHA256 (0xC027) and TLS_ECDHE_RSA_with_AES_256_CBC_SHA384 (0xC028)), which are considered weaker?

Microsoft weighs the relative risk and disruption to customer operations in choosing cipher suites to support. The RSA-CBC cipher suites haven't been broken yet. We've enabled them to ensure consistency across our services and products, and to support all customer configurations. However, they're at the bottom of the priority list. We deprecate these ciphers at the right time, based on the Microsoft Crypto Board's continuous assessment.
