OK so probably gone completely overboard on this however I want to ensure I present the right information to the customer and not to have a professional pen-tester blow my conclusions out of the water. All versions of SSL/TLS protocol support cipher suites which use DES, 3DES, IDEA or RC2 as the symmetric encryption cipher are affected. This attack (CVE-2016-2183), called "Sweet32", allows an attacker to extract the plaintext of the repetitive content of a 3DES encryption stream.As 3DES block size is only 64-bit, it is possible to get a collision in the encrypted traffic, in case enough repetitive data was sent through the connection which might allow an attacker to guess the cleartext.
IMPACT: Remote attackers can obtain cleartext data via a birthday attack against a long-duration encrypted session. On the left hand side, expand Computer Configuration, Administrative Templates, Network, and then click on SSL Configuration Settings.

And how to capitalize on that? if anyone has any experience, please share your thoughts. So I built a Linux box to run testssl.sh and ran individual scans against each port: Testing protocols (via sockets except TLS 1.2, SPDY+HTTP2), Version tolerance downgraded to TLSv1.2 (OK), Null Ciphers not offered (OK), Anonymous NULL Ciphers not offered (OK), Anonymous DH Ciphers not offered (OK), 40 Bit encryption not offered (OK), 56 Bit export ciphers not offered (OK), Export Ciphers (general) not offered (OK), Low (<=64 Bit) not offered (OK), DES Ciphers not offered (OK), "Medium" grade encryption not offered (OK), Triple DES Ciphers not offered (OK), High grade encryption offered (OK), So basically I've run a report that gives me the answers I'm looking for -, Heartbleed (CVE-2014-0160) not vulnerable (OK), no heartbeat extension, CCS (CVE-2014-0224) not vulnerable (OK), Secure Renegotiation (CVE-2009-3555) not vulnerable (OK), Secure Client-Initiated Renegotiation VULNERABLE (NOT ok), DoS threat, CRIME, TLS (CVE-2012-4929) not vulnerable (OK), BREACH (CVE-2013-3587) no HTTP compression (OK) - only supplied "/" tested, POODLE, SSL (CVE-2014-3566) not vulnerable (OK), TLS_FALLBACK_SCSV (RFC 7507), No fallback possible, TLS 1.2 is the only protocol (OK), FREAK (CVE-2015-0204) not vulnerable (OK), DROWN (2016-0800, CVE-2016-0703) not vulnerable on this port (OK), make sure you don't use this certificate elsewhere with SSLv2 enabled services Restart your phone to make sure none of the operational is disrupted by the changes you just performed. Internal services resides inside NetScaler and takes action on behalf of NetScaler. 5. How are things going on your end? // }
Choice of ciphers used has become critical as they ensure safety of data exchanged between client and server. Note 2284059 Update of SSL library within NW Java server, which introduces new TLS versions for outbound communication using the IAIK library. 3. 2. The following config passed my PCI compliance scan, and is bit more friendly towards older browsers: SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM SSLProtocol ALL -SSLv2 -SSLv3.
