- Discuss Allen's idea of strong security by default
Follow up in a new JIRA
- Refactor KMS scripts based on catalina.properties technique
Testing done
- Run https://github.com/jzhuge/hadoop-bats-tests/blob/master/kms.bats in
insecure and SSL single node setup
- Run sslscan to verify ciphers in the following test cases:
-- No KMS_SSL_CIPHERS, to allow KMS default ciphers
-- KMS_SSL_CIPHERS=“TLS_RSA_WITH_AES_128_CBC_SHA256“, to allow this cipher
only
> KMS should support old SSL clients

> Project: Hadoop Common
> Issue Type: Improvement
> Components: kms
> Affects Versions: 2.8.0, 2.7.4, 2.6.6
> Reporter: John Zhuge

> HADOOP-13812 upgraded Tomcat to 6.0.48 which filters weak ciphers. Old SSL
> clients such as curl stop working. The symptom is {{NSS error -12286}} when
> running {{curl -v}}.
> Instead of forcing the SSL clients to upgrade, we can configure Tomcat to
> explicitly allow enough weak ciphers so that old SSL clients can work.
