The security and performance are critical to DSPS. The authors suggested a key management scheme by combining the server group structure to improve availability and the key distribution structure needed by proactive security. This paper detailed the implementation of proactive security in DSPS. After thorough performance analysis, the authors concluded that the performance difference between the replicated mechanism and proactive mechanism becomes smaller and smaller with increasing number of concurrent connections; and that proactive security is very useful and practical for large, critical applications.展开更多
传统的数据库安全解决方案的缺点是不能很好地解决以合法身份进行的恶意攻击,对具有不同安全需求的用户,只能提供固定的安全级别,造成资源浪费。它采用多级安全模型,即“用户+ OS + DBMS +事务级入侵容忍”,将冗余和多样性技术相结合,...传统的数据库安全解决方案的缺点是不能很好地解决以合法身份进行的恶意攻击,对具有不同安全需求的用户,只能提供固定的安全级别,造成资源浪费。它采用多级安全模型,即“用户+ OS + DBMS +事务级入侵容忍”,将冗余和多样性技术相结合,采用整体安全策略及面向服务的入侵容忍技术,实现数据库的可生存性、可用性及关键数据的机密性、完整性,能有效抵御以合法身份进行的恶意攻击,降低安全成本。展开更多
