Transport Layer Security (TLS) protocol Version 1.2
Use the latest TLS security protocol to protect your site. This prevents attackers from exploiting weaknesses in older, less secure versions to steal sensitive data.
About this task
Note: If you are using HCL Commerce V9.1.19 or
later, see Transport Layer Security (TLS) protocol Version 1.3.Transport Layer Security (TLS) is a cryptographic protocol designed for secure network communications.
Requiring TLSv1.2 is part of updating to NIST SP 800-131A security standards. Consider NIST SP 800-131A for more enhancements to site security.
Procedure
To enforce the use of TLSv1.2 on your site, ensure that all supporting software
is using TLSv1.2:
For WebSphere Application Server version 9.0.5.13 and later, the default outbound TLS protocol configuration is
WebSphere Application Server versions earlier than 9.0.5.13 useTLSv1.3,TLSv1.2, which is recommended.SSL_TLSv2by default, which supports TLS 1.0, 1.1, and 1.2 for outbound communication. Since TLS 1.0 and TLS 1.1 are insecure, it is recommended to update the configuration toTLSv1.3,TLSv1.2.- Use the Transaction server Run Engine commands to set the SSL protocol for SSL configuration.
