Disable weak cipher in JIRA 8.4.2

[Deleted user]

Our monitoring tool reports that some weak SSL ciphers are active for our JIRA instance.

I tried to follow this article but I do not know where I could set these parameters. The only place I could imagine is here in the registry.

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Apache Software Foundation\Procrun 2.0\JIRA120914170711\Parameters\Java

Can anyone help?

Thanks!

Hi Marius

generally speaking you should look into the tomcat configuration (server.xml) and will need to tweak it there.

Atlassian has an official knowledgebase article on that

https://confluence.atlassian.com/kb/security-tools-report-the-default-ssl-ciphers-are-too-weak-755140945.html

In addition 

https://support.comodo.com/index.php?/Knowledgebase/Article/View/659/17/how-to----disable-weak-ciphers-in-tomcat-7--8

provides some details.

Please keep in mind that modifying the ciphers might disabled older browsers to work with your instance

All the best
