I can not say how this may affect your Ignition version (our install is 7.9.4), but the solution I found was to go into the JAVA home directory/installation. There you will find file java.security under /lib/security. Look for jdk.tls.disabledAlgorithms= where you can add “DSA, DESede, DES”.
In the ignition.conf file I added the following lines:
wrapper.java.additional.5=-DexcludedCiphers=SSLv3,TLSv1,DES-CBC3-SHA,DHE-RSA-DES-CBC3-SHA,DES,3DES, DESede, DES
I now have DES, 3DES, SSL3 and TLS1 disabled.
