The Secure Sockets Layer (SSL) protocol improves security by providing a digital certificate that authenticates storage systems and allows encrypted data to pass between the system and a browser. SSL is built into all major browsers. Therefore, installing a digital certificate on the storage system enables the SSL capabilities between system and browser.
Using SSL improves security by encrypting the administrator’s password and all administrative communication when you manage your system from a browser.
Data ONTAP supports SSLv2, SSLv3, and Transport Layer Security version 1.0 (TLSv1.0). You should use TLSv1.0 or SSLv3 because it offers better security protections than previous SSL versions.
As a precautionary measure due to security vulnerability CVE-2009-3555, the SSL renegotiation feature is disabled in Data ONTAP.
