Worked on security hardening for the marklogic-contentpump repository by deprecating legacy TLS protocols and updating the associated test suite. The main feature involved removing support for TLS 1.0, TLS 1.1, and other outdated protocols to enforce the use of modern, secure standards, thereby reducing the potential attack surface. This update required careful protocol management and a thorough review of existing Java-based tests to ensure compatibility with the new security requirements. The changes were tracked under MLE-21561 and implemented in Java, focusing on security best practices and robust validation of secure configurations without introducing any new bugs during the process.
