MOVEit uses Microsoft's built-in TLS/SSL security support provider (Schannel.dll). In all supported versions of Windows, there are several available protocols and cipher suite options enabled by default. Not all of them will meet your security and compliance needs. For example, the much older SSLv2 protocol is enabled by default on the server but is not allowed for PCI-compliant web applications. Be careful to choose the right mix of strong encryption methods and acceptable client support.
Warning: Changing the cipher suites or TLS/SSL versions can affect any applications that use TLS/SSL. Be sure you are aware of the requirements of other applications before making a change. For example, if you select SSL 2.0 only, MOVEit will not be able to connect to the Microsoft SQL database. The intent of this dialog is to allow you to avoid using a weak cipher where not allowed by PCI, FIPS, or other standards.
You can use the SSL tab to select the cipher suites and SSL versions that can be used when establishing an SSL session.
The SSL Cipher Suites section allows you to choose which cipher suites are permissible, and their order of preference. A cipher suite is a named combination of authentication, encryption, and message authentication code (MAC) algorithms used to negotiate the security settings. By default, all ciphers suites enabled in the base Windows OS are enabled.
Note: Both the client's and the server's preferences are taken into consideration when choosing the actual cipher for a given session. Though the server's first choice won't always be chosen, the cipher that ends up being chosen will always be in the set of allowed algorithms on both sides.
Select the Enabled check box to disable a selected entry or to enable an unselected entry.
Entries closer to the top of the list are given preference over entries lower down. Use the arrow buttons to move entries up or down in the list. Even if you must permit weaker cipher suites, you should always put the stronger ones at the top of the list.
SSL Versions are shown at the bottom of the SSL Tab. The default selections include SSL 2.0, SSL 3.0, and TLS 1.0. The versions selected determine the cipher suites that are available.
Select a check box to disable a selected version, or to enable an unselected version.
Note: After any SSL Version change, you need to reboot the system before the change takes effect.
Note: Be aware that the security policy setting System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing will restrict the available cipher suites and protocols. For example, TLS 1.0 will always be enforced.
Note: Be aware that the setting SSL cipher suite order via Group Policy will override any changes made to cipher suite order on this tab.
To test SSL changes, first obtain a copy of OpenSSL. You can get OpenSSL.exe from the OpenSSL Project. Consult the following examples which show how to use this client and understand the information it provides.
(You need to type the commands in purple. Look for the results in red.)
