How to Disable a Specific Cipher Suite from CSR Communication

From Content Security Reporter 2.8 and later.

  1. Navigate to C:\Program Files\Skyhigh\Content Security Reporter\jre\lib\security folder.
  2. Open the file with an editor of your choice.
  3. Search for the jdk.tls.disabledAlgorithms entry.

The current default entry is:
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \

  1. Add the information as a comma separated entry to jdk.tls.disabledAlgorithms=

For example, to disable TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, add the following, comma-separated entry:
jdk.tls.disabledAlgorithms=SSLv3, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, RC4, DES, MD5withRSA, DH keySize < 1024, \    EC keySize < 224, 3DES_EDE_CBC, anon, NULL

  1. Save the file and restart the CSR service.
