---------------------------------
Summary: Update to enable TLS >=1.2 as default secure protocols
Key: HDFS-15825
URL: https://issues.apache.org/jira/browse/HDFS-15825
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Ying Zhang
In file
client/src/main/java/org/apache/abdera/protocol/client/util/SimpleSSLProtocolSocketFactory.java
line 46, SSL protocol is used as a security protocol in statement *context =
SSLContext.getInstance("SSL");*
*Impact:*
An SSL DDoS attack targets the SSL handshake protocol either by sending
worthless data to the SSL server which will result in connection issues for
legitimate users or by abusing the SSL handshake protocol itself.
*Suggestions:*
Upgrade the implementation to the “TLS”, and configure https.protocols JVM
option to include TLSv1.2:
