NEW VALUE JCC_ENFORCE_SECMEC FOR DB2 REGISTRY VARIABLE DB2AUTH TO REJECT NON-ENCRYPTED USERNAMES AND PASSWORDS FROM JCC CLIENT | |
Produkt: | |
DB2 CONNECT / DB2CONNCT / A10 - DB2 | |
Problembeschreibung: | |
With the DB2 server authentication type SERVER_ENCRYPT a DB2 server accepts connections from an IBM Data Server Driver for JDBC and SQLJ client (also called JCC driver) even when the client's security mechanism is CLEAR_TEXT_PASSWORD_SECURITY. That means that the DB2 server accepts user names and passwords that are not encrypted from such clients. The DB2 server authentication type is set by the database manager configuration parameter AUTHENTICATION. The security mechanism is set by the of the IBM Data Server Driver for JDBC and SQLJ client property securityMechanism. To prevent the DB2 server from accepting such connections this APAR introduces a value JCC_ENFORCE_SECMEC for the DB2 registry variable DB2AUTH. To have the DB2 server not accept connections from an IBM Data Server Driver for JDBC and SQLJ client with security mechanism CLEAR_TEXT_PASSWORD_SECURITY when the DB2 server authentication type is SERVER_ENCRYPT, set the DB2 registry variable DB2AUTH to JCC_ENFORCE_SECMEC at the DB2 server. No application modification is required, except that if you use Oracle JVM and use the security mechanism ENCRYPTED_USER_AND_PASSWORD_SECURITY you must also have the IBM Data Server Driver for JDBC and SQLJ property encryptionAlgorithm set to 2, which means using 256-bit AES (strong) encryption. To use 256-BIT AES (strong) encryption with Oracle JVM, install the "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy" files from Oracle. | |
