How to disable 3DES and weak ciphers in Tomcat 8.5.15

Discussion in 'Apache' started by platetripn, Dec 21, 2018.

    Hello,

    I am being pinged by our security folks on scans stating that we still use 3DES ciphers. This system is running on a Windows Server. I have tried several different ways to add ciphers and lists of weak ciphers but when I run a scan I still show them being weak. I want to know where in the connector settings do I put the ciphers and what other options are needed to block weak ciphers? I appreciate any help you can give. Here is a copy of our scrubbed server.xml

    <?xml version="1.0" encoding="UTF-8"?>

    <Server port="8005" shutdown="SHUTDOWN">
    <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
    <!-- Security listener. Documentation at /docs/config/listeners.html
    <Listener className="org.apache.catalina.security.SecurityListener" />
    -->
    <!--APR library loader. Documentation at /docs/apr.html -->
    <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
    <!-- Prevent memory leaks due to use of particular java/javax APIs-->
    <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
    <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
    <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

    <!-- A "Service" is a collection of one or more "Connectors" that share

    I have looked at this link before. I am running Tomcat 8.5.15 and Java 8. If I input that list of ciphers does it mean that those are the stronger ciphers or a list of the weak ciphers that the site shouldn't use?

    There needs to be a much easier way to harden a site in Tomcat
