SSL: SSLv3 Brute Force Attempt
This signature is to detect large number of SSLv3 handshake attempt to SSL server from a particular client. Excessive attempts can indicate a Brute force attack against the SSL server.
Extended Description
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
