HCL Commerce Version 9.1.5.0 or later

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

HCL Commerce Version 9.1.19.0 or laterNote: 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 TLSv1.3, TLSv1.2, which is recommended.

    WebSphere Application Server versions earlier than 9.0.5.13 use SSL_TLSv2 by 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 to TLSv1.3,TLSv1.2.
  • Use the Transaction server Run Engine commands to set the SSL protocol for SSL configuration.

Results

All communications on your site are now made through TLSv1.2 only.
