I’'m currently working on PCI vulnerability compliance and the Spark / Wildfire server came up as having a weak SSL encryption. Essentially, any SSL encryption using less than 128-bit key is considered weak and needs to be remediated before we can pass the PCI compliance. After doing some research, I believe the SSL is running on port 5223.
Running on Windows 2003, AD/LDAp Auth, groups, vcard. Also using SSL for LDAP. Verion 3.2.4 of Wildfire is being used.
