Update TLS apache vhost TLS configuration (#5137):
. We want to allow for TLS1.2 to be enabled (supported in wheezy) . Explicitly disable SSLCompression. This aids in protecting against the BREACH attack: see http://breachattack.com), and SPDY version 3 is vulnerable to the CRIME attack when compression is on . Switch the cipher suites to match https://wiki.mozilla.org/Security/Server_Side_TLS#Apache for these reasons: . Prefer PFS, with ECDHE first then DHE (TLS 1.2, not many implementations support this, and there are no known attacks). . Prefer AES128 to AES256 because the key schedule in AES256 is considered weaker, and maybe AES128 is more resistant to timing attacks . Prefer AES to RC4. BEAST attacks on AES are mitigated in >=TLS1.1, and difficult in TLS1.0. They are not in RC4, and likely to become more dangerous . RC4 is on the path to removal, but still present for backward compatibility Change-Id: I99a7f0ebf2ac438f075835d1cb38f63080321043
