self encrypting ssd

Can ssd be used as a redo disk? 1. ssd has write wear and tear, and the ssd write performance is not very good. ssd is only very good for random reading, because it does not need to be searched. Ssd is easy to damage. 2. index tablespace and temporary tablespace are good cho

Under Linux, we have two main methods of encrypting files and directories. One is file system level encryption, in which you can selectively encrypt certain files or directories (for example,/home/alice). This is a great way for me, and you don't need to reinstall everything to enable or test encryption. However, file system-level encryption has some drawbacks. For example, many modern applications cache (partial) files in unencrypted portions of your

Computers are playing an increasingly important role in our work and life since we entered the era of information and networking. More and more users use computers to get information, process information, and keep their most important information in the form of data files in the computer. Some people describe the network as the most free world, where you can give full play to your imagination, to create a completely your own small universe, but if our network lacks the minimum security means, fr

When asked whether traditional raid can be built on SSD, the first response should be "yes, but trim command support is required ". On the Internet, we can also see that many people use SSD to create raid, but basically it is configured as RAID 0 or raid 1. Few people will build RAID5. Why? The answer is very simple. If you configure parity-raid like RAID 5 on the basis of

There should be a lot of friends accessing the Internet through a wireless router. Have you noticed that your router is being watched by others? Is there an encrypted wireless router? Please refer to the following link for more information. Relatively speaking, wireless networks are more difficult to protect than wired networks, because the number of fixed physical access points in a wired network is limited, and any point that can be achieved by the wireless network signal may be used. Therefor

random numbers, so clear text can not take 128 bytes full, the actual test, clear text up to 117 bytes, leaving space to fill the random number.So, using the same key to encrypt the same string of strings, each time you get the ciphertext is not the same.4. Decryption operationTo load a certificate from a certificate file, if you have a private key, you need to provide the password you set when saving the certificateX509Certificate2 Myx509certificate2 = Newx509certificate2 (@ "c:/samples/partne

Customers generally do not agree with this method of saving data in config file. Specifically, the customer is concerned with how to save sensitive information in a text file. When encountering this type of customer, the author will tell them that if other people can remove text files from their Web server, their problems cannot be solved. But the client is not aware of the need for this argument. In fact, they have their own point of view. A considerable portion of the security vulnerabilitie

I haven't updated my blog for a long time. A while ago, I experienced my first job hopping, which is much harder than I thought. After all, it was the first job and it was quite sad to leave. The new job has just begun, and we hope everything will go well. This blog was written during May 1, and is officially posted today. It is a good habit to write a technical blog. I want to keep it! When I was in the previous job, I always wanted to try Flash/SSD
