Field level Encryption in Oracle DB using PHP
Hi!
I am using Oracle DB and PHP Scripting application for developing a ERP product.
How can Secure the Data stored in Oracle DB?
1.Can i encrypt the Data in PHP and Store the Same in DB? Whether it will affect the System Performance.
2. Can i do the encryption using Oracle in the Back End? Whether it is possible and whether it is a Suggestable method?
3. If i am using field level encryption, whether the performance server gets affected in the Application server or DB server.
4. Whether it is enough to keep the Oracle Database in Linux server as very secure and encrypt only the passowrd & Credit card details?
Please give your suggestions regarding the same.
