Many DBMS products in the market provide built in encryption support to deal with the security concerns of the organizations. This solution is quite effective in preventing data leakage from compromised/stolen storage devices. However, recent studies show that a significant part of the leaked records have been done so by using specialized malwares that can access the main memory of systems. These malwares can easily capture the sensitive information that is decrypted in the memory including the cryptographic keys used to decrypt them. This can further compromise the security of data residing on disk that are encrypted with the same keys.
