Scanning For and Finding Vulnerabilities in Supported SSL Ciphers Suites
Use of Vulnerability Management tools are standard practice for the discovery of this vulnerability. The primary failure of VA in finding this vulnerability is related to setting the proper scope and frequency of network scans. It is vital that the broadest range of hosts (active IPs) possible are scanned and that scanning is done frequently. We recommend weekly. Your existing scanning solution or set of test tools should make this not just possible, but easy and affordable.
Penetration Testing (pentest) for this Vulnerability
The Vulnerabilities in Supported SSL Ciphers Suites is prone to false positive reports by most vulnerability assessment solutions. Fortra VM uses behavior based testing that eliminates this issue. For all other VA tools security consultants will recommend confirmation by direct observation. In any case Penetration testing procedures for discovery of Vulnerabilities in Supported SSL Ciphers Suites produces the highest discovery accuracy rate, but the infrequency of this expensive form of testing degrades its value. The ideal would be to have pentesting accuracy and the frequency and scope possibilities of VA solutions, and this is accomplished only by AVDS.
