You should disable SSL renegotiation as it is vulnerable to the man-in-the-middle attacks.
Perform the following steps to disable SSL renegotiations in Analytics Server:
Open the /opt/novell/nam/dashboard/conf/tomcat.conf file.
Ensure that the following lines exist:
JAVA_OPTS="${JAVA_OPTS} -Dsun.security.ssl.allowUnsafeRenegotiation=false"
JAVA_OPTS="${JAVA_OPTS} -Djdk.tls.rejectClientInitiatedRenegotiation=true"
