文章以数据库安全为出发点,介绍了入侵容忍技术的目标、实现机制、安全策略和原理。在此基础上,提出了一种多级入侵容忍技术,将冗余与多样性技术相结合,能够有效抵御针对数据库的安全攻击,实现了数据库的完整性、可用性。
The article takes the database security as a starting point, introduces the goal of intrusion tolerance technology, and realizes the mechanism, security strategy and principle. On this basis, a multi-level intrusion tolerance technology is proposed, combining the redundancy and diversity technologies, which can effectively resist the security attacks against the database and achieve the integrity and availability of the database.
