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 data encryption, it is not TDE, but it

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 SQL Server2008 security option, and with it we can at lea

write cache exists and the algorithm is normal, RAID5 is even better than raid10, although there may not be much difference (here we should assume that there is a certain size of storage, enough write cache, and there is no bottleneck in the CPU for computing and verification ).
This is because the raid check is completed in the cache. For example, for RAID 5 of four disks, you can calculate the check in the memory and write three data and one verification at the same time. Raid10 can only wr
