  1. CUBRID's Development Culture: The Development Process and Improvements Behind

    Written by Hyung-Gyu, Ryoo on 07/16/2021   Foreword Hello, I am Hyung-Gyu Ryoo, I am working in CUBRID as a research engineer in the R&D department. In this post, I would like to introduce the development process of the open source project CUBRID and the efforts we have made to improve the process.   It has been almost two and a half years since I joined CUBRID.  During this period, as many great fellow developers have joined the CUBRID community, the R&D department of CUBRID has grown from one small team to three developments teams along with a QA team.   After I participated in the first major version release (CUBRID 11), I was able to look back to the release process and improve the development process with my fellow developers.     The Development Process of the Open Source Data...

  2. TDE (Transparent Data Encryption) in CUBRID 11

    Written by Jiwon Kim on 07/07/2021 👍Increase the level of database security by utilizing various security features of CUBRID. CUBRID 11 has enhanced security by providing the Transparent Data Encryption (henceforth, TDE) feature. So, what is TDE? TDE means transparently encrypting data from the user’s point of view. This allows users to encrypt data stored on disk with little to no application change. When a hacker hacks into an organization, the number one thing they want to steal is the important data in the database. Alternatively, there may be a situation where an employee with malicious intention inside the company logs into the database and moves all data to a storage media such as a USB.  The easiest way to protect data in these situations is to encrypt the database. TDE, a technolog...

  3. Preventing Sniffing by CUBRID- Packet Encryption

      Written by Youngjin Hwang on 05/11/2021   Nowadays, browsing the internet with PCs or our smartphones has become an essential part of our daily life. As a result, it is possible to peek into the data being transmitted over the Internet with malicious intent. In other words, being able to peek at the data being transmitted by someone is called sniffing.   A classic example of a sniffing attack would be intercepting the account’s id and password and causing physical damage by using the personal information of others.   To protect our database user data, CUBRID 11.0 has enhanced security by providing packet encryption (and TDE (Transparent Data Encryption) based data encryption, but that will be cover in another blog later). When packet encryption is applied, the packet is encrypted and tran...

  4. Contributing to Open Source Community/Project

      Written by Charis Chau on 06/23/2020      What is an open source project? To answer this, let us start with a burger! Imagine an open source project is a burger selling in a restaurant. Every day, the chef makes thousands of burgers that have the same quality by following the same recipe from the restaurant. One day, customer A comes to the burger place to try the burger, and he/she loves it! Therefore, customer A decides to ask the chef whether he/she can get the recipe. Here, if the restaurant is open source, they will be happy to share the recipe to customer A, vice versa.     After customer A gets the receipt, he/she decide to make the burger at home by him/herself! However, customer A is a meat lover and does not like onion that much, so he/she decide to change the recipe by taking o...

  5. CUBRID License Model

    Written by Charis Chau on 06/08/2020   Why Licenses Matter?   Open source licenses allow software to be freely used, modified, and shared. Choosing a DBMS with suitable licenses could save the development cost of your application or the Total Cost of Ownership (TCO) for your company. Choosing a DBMS without a proper license, you might find yourself situate in a legal grey area!     CUBRID Licenses   Unlike other open source DBMS vendors, CUBRID is solely under open source license instead of having a dual license in both commercial license and open source license. Which means that for you, it is not mandatory to purchase a license or annual subscription; company/organizational users can achieve the saving from Total Cost of Ownership (TCO).   Since CUBRID has been open source DBMS from 2008,...
