SSL Version 2 & 3 Protocols Have Been Deprecated Reason for change These protocols have known and high-profile security vulnerabilities. Change Definitions for SSLv2 and SSLv3 remain in the image, however usage of these when configuring an SSL connection will result in a runtime error. Action required Modify any references to the following pool variables (from SciSslConstants) to a more secure protocol reference such as SSLv23 or any of the TLS prefixed protocols found in SciSslConstants. Contrary to the naming convention, SSLv23 actually favors TLS based protocols with a possible fallback to SSLv3 and is suitable for use. Deprecated Protocol References: SSLv2, SSLv2_client, SSLv2_server, SSLv3, SSLv3_client, SSLv3_server
