Oracle TDE: Keep Your Data Safe and Secure（oracletde）

Data security is becoming one of the most important aspects of IT operations today, especially as businesses become increasingly reliant on digital data for day-to-day operations. With data breaches, cyber-theft, and cyber-crime taking place with alarming regularity, organizations of all sizes must take action to protect and secure the sensitive data that is stored in their IT systems. One of the best ways to ensure data security is through the use of Oracle TDE (Transparent Data Encryption).

Oracle TDE is a feature within the Oracle Database that allows users to encrypt data stored in the database, as well as application data, while still allowing them to access the data as if it were not encrypted. This allows users to store sensitive information in an encrypted format, which is a critical layer of safety and security. Oracle TDE is also easy to implement and use; once the encryption keys have been generated and configuration is complete, it requires no additional administrative effort to keep data encrypted.

Some of the key benefits of Oracle TDE include:

• Data is encrypted at the level of individual columns in the database. This means that there is no need to re-architect applications; instead, the data is simply encrypted as it is added to the database.

• Data is encrypted and decrypted in motion. This means that the data is encrypted and decrypted as it moves between the user and the database, so the data is never exposed in an unsecure state.

• Oracle TDE can be used with applications of all types, including web applications, so data is secure no matter how it is accessed.

• Oracle TDE is an easy and cost-effective way to protect data against cyber-attack.

To get started with Oracle TDE, organizations must first generate and store encryption keys, and then configure the TDE settings in the Oracle database. This can be done using the Oracle keystore, which is a secure repository for storing encryption keys. Once encryption keys have been generated and stored in the keystore, organizations can set up TDE using the following code:

ALTER SYSTEM SET ENCRYPTION_WALLET_LOCATION=’*location of the keystore*’

ALTER SYSTEM SET ENCRYPTION_WALLET_TYPE=’S’

ALTER SYSTEM SET ENCRYPTION_ARG0=’ENC-ALG-3DES168’

Once the code is entered and the settings have been configured, organizations can enable TDE in their Oracle database. To enable TDE, users simply need to use the following code:

ALTER TABLESPACE *tablespace_name* ENCRYPTION USING ‘AES128’ WITH ENCRYPTION KEY ’*encrypted_key*’

Once TDE has been enabled, organizations can then encrypt specific columns in their database using the following code:

ALTER TABLE *table_name* ADD ENCRYPTION(COLUMN *column_name* USING ‘AES128’)

By using Oracle TDE, organizations can ensure that their data remains safe and secure. Encrypted data is protected from malicious actors, and organizations can rest assured knowing that their sensitive data will be secure from potential cyber-attacks.
