Secure all remote connections by using SSL

AltaNivel 1Revisión manualdb2-zos

Descripción

The z/OS communications server for TCP/IP supports the Application Transport Transparent Layer Security (AT-TLS) function. AT-TLS performs TLS on behalf of Db2. It invokes the z/OS system SSL in the TCP layer of the TCP/IP stack and protects the transmission of data. It is recommended to configure AT-TLS to use SSL connections to secure all Db2 remote access.

1. See "Encrypting your data with Secure Socket Layer (SSL) support" and "IBM Db2 for z/OS: Configuring TLS/SSL for Secure Client/Server Communications" for more information. 2. To allow only SSL connections to Db2, verify that the TCP/IP PORT field is set to the same value as the SECURE PORT field and that both static and dynamic subsetting location aliases are defined with the same value as PORT and SECPORT.
