Quality of protection (QoP) settings

Use this page to specify security level, ciphers, and mutual authentication settings for the Secure Socket Layer (SSL) configuration.

To view this console page, click Security > SSL certificate and key management > Manage endpoint security configurations > {Inbound | Outbound SSL_configuration_name}. Under Related Items, click SSL configurations > {SSL_configuration_name | New}. Under Additional Properties, click Quality of protection (QoP) settings.

 

Configuration tab

Client authentication

Specify the whether SSL client authentication should be requested if the SSL connection is used for the server side of the connection.

If None is selected, the server does not request that a client certificate be sent during the handshake. If Supported is selected, the server requests that a client certificate be sent. If the client does not have a certificate, the handshake might still succeed. If Required is selected, the server requests that a client certificate be sent. If the client does not have a certificate, the handshake fails.

Data type:	Text
Default:	None

Protocol

Specify the SSL handshake protocol. This protocol is typically SSL_TLS, which supports all handshake protocols except for SSLv2 on the server side. When United States Federal Information Processing standard (FIPS) option is enabled, Transport Layer Security (TLS) is automatically used regardless of this setting.

Data type:	text
Default:	SSL_TLS

Predefined JSSE provider

Specify one of the predefined Java Secure Sockets Extension (JSSE) providers. The IBMJSSE2 provider is recommended for use on all platforms which support it. It is required for use by the channel framework SSL channel. When Federal Information Processing Standard (FIPS) is enabled, IBMJSSE2 is used in combination with the IBMJCEFIPS crypto provider.

Default:

Enabled

Select provider

Specify a package that implements a subset of the cryptography aspects for the Java security API. This value is a JSSE provider name that is listed in the java.security file. Note that cipher suites and protocol values depend upon the provider.

Data type:	Text
Default:	IBMJSSE2

Custom JSSE provider

Specify that a custom JSSE provider should be used.

Default:

Disabled

Custom provider

Specify a package that implements a subset of the cryptography aspects for the Java security API. This value is a Java Secure Sockets Extension (JSSE) provider name that is listed in the java.security file. Note that cipher suites and protocol values depend upon the provider.

Data type:

Text

Cipher suite groups

Specify the various cipher suite groups that can be chosen depending upon your security needs. The stronger the cipher suite strength, the better the security; however, this can result in performance consequences.

Data type:	Text
Default:	Strong

Update selected ciphers

When selected, the cipher suites that are contained within the selected Cipher suite group are added to the list of Selected ciphers. Any change to this list changes the Cipher suite group to custom.

Selected ciphers

Specify the ciphers that are effective when the configuration is saved. These ciphers are used to negotiate with the remote side of the connection during the handshake. A common cipher needs to be selected or the handshake fails.

Data type:

Text

Add

Specify to add the selected cipher to the Selected ciphers list.

Remove

Specify to remove the selected cipher from the Selected ciphers list.
