For a database administrator, security is one of the most important aspects to consider when protecting a database that you support. We use a variety of mechanisms and techniques to protect our data and databases, such as firewalls, authentication, and data encryption. But although we set security for our environment, there are always problems with database secur
TDE encryption and Cracking Analysis of Microsoft SQL Server transparent data (Part 1) This survey started with a discussion with the customer about whether they should install TDE. If we want to select the most suitable tool for static
Problem Security is a major consideration for any company. Database backups are easily stolen and restored to another instance of SQL Server. As we explore the new features of SQL Server 2008, we are interested in a feature called Transparent

When a user database is available and TDE is enabled, encryption is implemented at the page level when it is written to disk. Decrypts when the data page is read into memory. If a database file or database backup is stolen, the original certificate that is not used for encryption will not be accessible. This is almost the most exciting feature of the
In the real environment, we will encounter the loss or theft of database backup disks. At this time, malicious destructive parties only need to restore or attach the database to view data. Next, I will introduce the Transparent Data Encryption method to protect your database. If da
Oracle's transparent data encryption is part of Oracle's Advanced Security Options and requires additional software fees. This option can be encrypted in combination with multiple means, including using Wallet (PKCS #12 standard) and supporting PKCS #11 RAS hardware devices. In 10 Gb, transparent
versions.An important security concept is defense-in-depth, which means that the best security is layered rather than relying on a single layer of protection. After your network, server, instance of SQL Server, and database security, you can add the last powerful layer of data protection by encrypting sensitive
