Disabling TLSv1, TLSv1.1 in logstash tcp input is not working in Logstash 6.8.23

[epadmav]

In Logstash 6.8.23 , we have followed the below-mentioned approaches to disable TLSv1, TLSv1.1.

1)Modified /usr/java/jdk1.8.0_231-amd64/jre/lib/security/java.security with the below content:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1 keySize < 2048,
RC4, DES, MD5withRSA, DH keySize < 1024,
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

Still TLSv1, TLSv1.1 is not disabled.

2)Tried disabling TLSv1, TLSv1.1 through custom security configuration setup by following the below steps:

a) Created a directory jvm.options.d in /etc/logstash/conf.d
b) Created a file java.security.options in /etc/logstash/conf.d/jvm.options.d
c) Appended the below content in /etc/logstash/conf.d/jvm.options.d/java.security.options
-Djava.security.properties=/etc/logstash/es.java.security
d) Created a file es.java.security in /etc/logstash directory
e) Added the below content in es.java.security file

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA,
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

This approach is also not working in logstash 6.8.23 version. Could you please let me know if any other configuration changes need to be done or if there is any alternate approach to disable TLSv1,TLSv1.1 in logstash 6.8.23 version? Thanks in Advance

Any updates on this? Looking for a lowest supported version of the TCP plugin that supports the TLS restriction. Thanks.
