摘要
一、引言从网络安全防护体系来看,网络安全应当由安全防护、动态检测和攻击反应等环节组成,安全防护环节通过防火墙、访问控制和身份认证等技术提供基本的网络安全保护,既要保证合法用户能够访问网络资源,又要保护网络系统不受非法用户的入侵,它是网络安全的基础;动态检测环节通过漏洞扫描和入侵检测等技术对网络系统安全状况进行监控和检测,及时发现攻击者的入侵行为,并适时发出安全警告;攻击反应环节在系统遭受攻击时通过攻击阻断和灾难恢复等技术适时地做出反应,将损失减少到最低程度.
Fast balefulness restore technology is an importance part of network security architecture . It can reduces system loss and fast restores system functions while the system is attacked or occurs fault. In this paper, a SAN (Storage Area Network )-based Balefulness Restore system and resource management technology for the system are discussed. The system provides high balefulness tolerance performance and effectively ensures network information system security by system fault tolerance and dynamic backup/restore technology.
