Abstract
With the rapid development of information technology, the database, as the core component of information storage and management, is facing an increasingly severe security threat. In order to effectively deal with intrusion behavior and ensure data security, this research focuses on the intrusion detection and defense technology of database, aiming to build a set of efficient, intelligent and adaptable security protection system. Based on in-depth analysis of existing intrusion detection and defense techniques, combined with machine learning algorithms and behavioral pattern recognition methods, this paper, a comprehensive detection model integrating multi-source heterogeneous data is proposed. By monitoring the database operation log, network traffic and user behavior characteristics, the model realizes the accurate identification and rapid response to abnormal activities. The experimental results show that the proposed model is better than the traditional methods in key performance indicators such as detection rate and false alarm rate, especially showing significant advantages in handling complex attack scenarios. In addition, according to the identified intrusion behavior, a multi-level and multi-strategy defense mechanism was designed, including access control enhancement, data encryption transmission and emergency response plan, which effectively improved the overall security of the system.
