As a very important storage tool, the database often stores a large amount of valuable or sensitive information, including financial finance, intellectual property, and enterprise data. Therefore, the database is often the main target of hackers. Cyber hackers use a variety of ways to get the information they want, so it's important to keep your database secure. Top 10 Most Common Database Security Issues While recognizing the importance of database security, developers still make some mistakes when integrating applications or patching vulnerabilities and updating databases, allowing hackers to take advantage of it. This article lists the 10 most common security issues for database systems. 1. Falsely deploying the developer's carelessness during the deployment process can easily put the database in jeopardy. In reality, some companies will realize the importance of optimizing search engines for business success, but SEO can optimize them only if the database is sorted. Although functional testing guarantees performance, testing does not anticipate what happens to the database. Therefore, a thorough review of the database is necessary before full deployment. 2. Data Disclosure You can use the database as part of the back-end setup and focus on protecting the Internet. It is easy for hackers to manipulate the network interfaces in the database. Therefore, in order to avoid this phenomenon, engineers are doing database development. It is especially important to encrypt communication platforms using TLS or SSL. 3. Database Maintenance Do you remember the 2003 SQL Slammer worm, which exploited the vulnerability of SQL Server to spread the world, causing the world to be paralyzed, and 80% of China's Internet users are affected. The success of the worm fully illustrates how important it is to protect database security. Unfortunately, few companies in the real world offer regular patches to their systems, so they are vulnerable to worm attacks. 4. Database backup information is stolen Usually, database backup information leakage will generally come from two ways, one is external and the other is internal. This is a problem that many companies often encounter, and the only way to solve this problem is to encrypt the file. 5. Abuse of database features According to experts, every hacked database will abuse database features. For example, a hacker can enter the system at will without the system executing. The solution to this problem is to remove unnecessary tools. 6. Infrastructure weak hackers generally don't control the entire database right away. On the contrary (+ WeChat networkworldweixin), they will choose to play hopscotch games to discover weak places in the infrastructure, and then use the advantages of the place to launch string attacks. Until reaching the back end. 7. Lack of isolation gives administrators and users a division of responsibilities. If they try to steal data, internal employees will face more difficulties. Therefore, limiting the number of users, so hackers want to control the entire database will have certain challenges. 8. SQL Injection Once the application is injected with malicious strings to trick the server into executing commands, the administrator has to clean up the mess, which is a major problem in protecting the database. The best solution at the moment is to use a firewall to protect the database network. 9. Improper key management It is very important to ensure key security, but the encryption key is usually stored on the company's disk drive. If you are unguarded, your system will be vulnerable to hacking. 10. Illegal operations Developers can use tracking information/log text to query and resolve such issues.
