![]() ![]() Which means that instead of a single key to encrypt and decrypt the whole database, each column has its own security key.Įxtra processes will eat up more computing power. Column-level encryption is commonly used for the Plug-in method. When it comes to plug-in or package encryption, an independent encryption module is attached to the application. As a result, API encryption can be suitable for small companies but can be very time-consuming when there’s big data involved. However, this kind of encryption requires a lot of manual management. They are all similar and work with many database management systems. There are several methods that use API encryption (Application Programming Interface encryption). ![]() Types of database encryption and their impact on performance Application encryption But those who encrypt their databases use encryption either on the application level, system level, or network level. Sadly, we see way too many vulnerabilities on this front. You would assume anyone sitting on a goldmine of data knows about the threats. Since hackers know about all this data, they will try to get their hands on it. We’re talking yottabytes of information that Google, Amazon, Facebook, and governments hold on us. These days, we’re dealing with incredible amounts of data. Data in use - active data which is typically stored in RAM or CPU cache.Data in transit - data that was taken from the database and is sent through the network.Data at rest - information in the database that is not being used.Database encryption works differently because the information in the database is constantly modified. If you’re using NordLocker, you may think of encryption as putting a file into a digital safe until you need it. The way NewSQL is being developed can prove to be a revolution for dealing with lots of live data. It combines the power of SQL structure with the speed and scalability of NoSQL databases. Lastly, it’s worth mentioning another new type of database. They don't require data to be as structured as in SQL.This method works better for big data and real-time web applications like Facebook or Amazon. Now there’s a growing interest in a new database type that is called a NoSQL database. If you wanted, you could filter our undone, medium-priority tasks that were due last week and are tagged as Family. Think about the apps you use daily like a task manager. A database management system (DBMS) can connect many such databases and answer extremely precise queries. A similar database could track meals or distance walked. Imagine a table tracking daily calorie consumption with columns for days and calories. SQL, which stands for Structured Query Language, is a language used to manage relational databases, which deal with highly structured data. But does it? Database 101: types of databasesīefore we talk about encryption, let’s quickly cover databases and how they are used.įor a long time, the market was dominated by SQL databases. Database encryption is meant to protect us. That’s why they are hackers’ favorite midnight snack. But think about the secrets databases keep: names, passwords, recovery questions, addresses, bank deposits. Doesn't this word make you yawn?ĭa-ta-base. ![]()
