What are the recommendations for database reinforcement and security protection? Many novices are not very clear about this. In order to help you solve this problem, the following small series will explain it in detail for everyone. Those who have this need can learn from it. I hope you can gain something.

As an important work at the national level to promote the network security protection and Incident Response Service level of important information systems and key basic information infrastructures in various industries, it is of great significance to promote the improvement of network security assurance capability by means of actual combat, confrontation and iteration. HW-2020 is coming soon. As an important carrier of business system data, database may become an important breakthrough point for attackers if its security defense is not perfect and its protection strength is not enough. Therefore, we suggest that users in various industries should strengthen database construction and increase the investment in database security protection to avoid core business database from SQL injection attack or unauthorized access. Database Hardening and Security Protection

As the core of carrying critical data, databases generally face the following security risks, such as:

1. SQL injection

2. database vulnerability

3. Default accounts and weak passwords

4. Unauthorized access...

Therefore, aiming at the security threat faced by the database, Meichuang Science and Technology Security Laboratory suggests that users should do a good job of self-inspection in the defense work, and strengthen and protect the security through data security protection products + security service form from three dimensions: vulnerability investigation, security reinforcement and monitoring response.

1. Use database vulnerability scanning tools to detect various vulnerabilities in the database, including SQL injection vulnerabilities, privilege bypass vulnerabilities, buffer overflow vulnerabilities, access control vulnerabilities, denial of service vulnerabilities, etc., and provide professional and effective security analysis and repair suggestions for administrators before the database is compromised to solve existing database vulnerabilities.

2. Strengthen database access management, realize multi-element identity management according to database account, application fingerprint, host name, IP address, time, operation behavior, CA authentication, etc., and prevent password guessing and brute force cracking.

3. Deploy database firewall between database and application server, analyze database access and response data flowing through, detect and actively block various attacks and security risks against database in real time, including attacks using database vulnerabilities, SQL input attacks using application programs, database DDOS attacks, fake application intrusions, database dragging/collision, high-risk operations, etc., to ensure database and core data security.

4. Use the data security management center to uniformly monitor all kinds of risk behaviors and operation status of various security systems, so as to avoid attackers from using unknown methods to attack and affect service status. At the same time, once various risk behaviors and abnormal operation status occur, it will give rapid alarm, analyze and count the risk source, target and content, and help the emergency team to judge and judge the alarm behavior in the shortest time to realize rapid response and disposal.

For individual key business systems, it is recommended to select professional security service teams to conduct penetration tests on database application systems, MS-SQL, Orcale, MySQL, DB2 and other database application systems, including default account password and weak password attacks, storage vulnerability process attacks, database operation permission detection, authorization vulnerability attacks, etc., and to conduct database protection reinforcement for test results.
