I included this bit in a couple of hardening guides, one for DOcean and the other for this very site of mine. Reputation is at stake when visitors to a site can be harmed. During the last months I’ve personally observed many sites adopting a better posture towards security by securing their headers. Not even Ansible is capable of defeating that in any easy way. What are these servers? Probably, many of them, are corporate servers where administrators, developers and other IT creatures are trapped under the boot of burocracy and the alleged efficiency of very little technical staff and lots of management souls. Just extract the 3.148.344 servers using the still supported TLS 1.2 from the total 7.170.224 found by Shodan.io and off we go. Shodan.io has a report on this specific, it’s not me with a crystal ball.

Java HotSpot(TM) 64-Bit Server VM (build 23.This is an article willing to help and point out a few useful resources for those using Apache HTTP or NGINX web servers that are still using the deprecated SSLv3, TLS 1.0 and/or TLS 1.1 verions.

Note: since POODLE, I would like to administratively disable SSLv3 system wide. How do I administratively enable TLS 1.1 and 1.2 system wide? I'm interested in enabling the protocols on a system wide setting (perhaps through a config file), and not a per-Java-application solution. SunJSSE does not enable TLS 1.1 or TLS 1.2 by default for client Refuse to talk to TLS 1.1 or TLS 1.2 clients. Some servers do not implement forward compatibility correctly and From Java Cryptography ArchitectureĪlthough SunJSSE in the Java SE 7 release supports TLS 1.1 and TLSġ.2, neither version is enabled by default for client connections. Java 7 disables TLS 1.1 and 1.2 for clients.
