Do Not Use Encryption Algorithms that are Not Secure

低等級 2人工審核db2

說明

Encryption can be performed with various algorithms, some of which are outdated and should no longer be used.

檢查方式

稽核方法: 人工審核

此項建議無法自動檢查。當您傳入 --include-manual 時，掃描結果會列出此項目並附帶這些說明。

Check that you are not using an outdated algorithm (like 3DES) by looking at the configuration settings.

修補方式

To determine what encryption options used to encrypt the database you can run the following command: db2 => get db cfg | grep -i encrypt Encryption Library for Backup (ENCRLIB) = libdb2encr.so Encryption Options for Backup (ENCROPTS) = CIPHER=AES:MODE=CBC:KEY LENGTH=256 Encrypted database = YES ENCROPTS should not contain CIPHER=3DES algorithm, because 3DES is not secure. CIPHER=AES is secure. You can also check the current database encryption settings: db2 => SELECT * FROM TABLE(SYSPROC.ADMIN_GET_ENCRYPTION_INFO()) You must be connected to the database to run this command. From the information retrieved, the ALGORITHM should not be 3DES.
