Du to vulnerabilities in SSL, for example POODLE, Cryptzone has implemented TLS 1.2 on "sep://" connections and TLS 1.0 on "https://" connections from version 220.127.116.11 and newer.
Due to known issues in SSL v3 all existing customers are advised to upgrade to this version (18.104.22.168) or newer.
SEP server: To disable SSL v3 and enforce minimum TLS 1.0:
Upgrade the SEP Server to 5.0.42 (or later)
- Stop the SEP Server.
- Add the following line to configuration.xml file that resides in the SEP Server installation directory:<DisableSslv3>True<DisableSslv3>
- Save the file.
- Start the SEP Server.
After this change, SEP Clients older than 5.0.81 will not be able to connect using sep:// protocol. However the https:// protocol will continue to work.
SEP Clients v 5.0.81 or newer can use both sep:// and https:// protocols, while talking to a SEP Server with min TLS 1.0 enforcement.
