Rajini Sivaram commented on KAFKA-3665: --------------------------------------- [~ijuma] [~junrao] I dont believe HTTPS validates client hostname/IP address and Kafka definitely doesn't. For client requests that go through a VIP for the initial request, each broker's certificate would need SubjectAltNames with the VIP as well as its advertised host name. > Default ssl.endpoint.identification.algorithm should be https > ------------------------------------------------------------- > > Key: KAFKA-3665 > URL: https://issues.apache.org/jira/browse/KAFKA-3665 > Project: Kafka > Issue Type: Bug > Components: security > Affects Versions: 0.9.0.1 > Reporter: Ismael Juma > Assignee: Ismael Juma > Fix For: 0.10.0.0 > > > The default `ssl.endpoint.identification.algorithm` is `null` which is not a > secure default (man in the middle attacks are possible). > We should probably use `https` instead. A more conservative alternative would > be to update the documentation instead of changing the default. > A paper on the topic (thanks to Ryan Pridgeon for the reference): > http://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf -- This message was sent by Atlassian JIRA (v6.3.4#6332)
