Usage guidelines

SSL employs the following algorithms:

·     Data encryption algorithms—Encrypt data to ensure privacy. Commonly used data encryption algorithms are symmetric key algorithms. When a symmetric key algorithm is used, the SSL server and the SSL client must use the same key.

·     Message Authentication Code (MAC) algorithms—Calculate the MAC value for data to ensure integrity. Commonly used MAC algorithms include MD5 and SHA. When a MAC algorithm is used, the SSL server and the SSL client must use the same key.

·     Key exchange algorithms—Implement secure exchange of the keys used by the symmetric key algorithm and the MAC algorithm. Commonly used key exchange algorithms are usually asymmetric key algorithms, such as RSA.

After the SSL server receives a cipher suite from a client, the server compares the received cipher suite with the cipher suits it supports. If a match is found, the cipher suite negotiation succeeds. If no match is found, the negotiation fails.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Configure SSL server policy policy1 to support the following cipher suites:

·     Key exchange algorithm DHE RSA, data encryption algorithm 128-bit AES, and MAC algorithm SHA.

·     Key exchange algorithm RSA, data encryption algorithm 128-bit AES, and MAC algorithm SHA.

Predefined user roles

network-admin

Parameters

size: Specifies the maximum number of cached sessions, in the range of 100 to 1000.

Usage guidelines

The SSL handshake protocol follows a complicated procedure to negotiate session parameters and establish sessions. To simplify the procedure, SSL allows you to reuse negotiated session parameters to establish sessions. This feature requires that the SSL server maintain information about existing sessions.

This command limits the maximum number of sessions that the SSL server can cache. If the number of sessions in the cache reaches the maximum, SSL does not cache new sessions.

Examples

# Set the maximum number of cached sessions to 600.

Parameters

policy-name: Specifies an SSL client policy by its name, a case-insensitive string of 1 to 31 characters.

Usage guidelines

This command creates an SSL client policy for which you can configure SSL parameters that the client uses to establish a connection to the server. The parameters include a PKI domain and a preferred cipher suite. An SSL client policy takes effect only after it is associated with an application such as DDNS.

undo ssl version { ssl3.0 | tls1.0 | tls1.1 } * disable

In FIPS mode:

ssl version { tls1.0 | tls1.1 } * disable

Default

In non-FIPS mode, the SSL server supports SSL 3.0, TLS 1.0, TLS 1.1, and TLS 1.2.

Usage guidelines

To enhance system security, you can disable the SSL server from using specific SSL protocol versions (SSL 3.0, TLS 1.0, and TLS 1.1) for session negotiation.

Disabling an SSL protocol version does not affect the availability of earlier SSL protocol versions. For example, if you execute the ssl version tls1.1 disable command, TLS 1.1 is disabled but TLS 1.0 is still available for the SSL server.

Examples

# Disable SSL 3.0 for the SSL server.

[Sysname] ssl version ssl3.0 disable

version

Use version to specify an SSL protocol version for an SSL client policy.

Use undo version to restore the default.
