灾难恢复计划

• It s far cheaper to identify vulnerabilities and put in place cost - effective safeguards , such as a disaster recovery plan and a daily backup system , than to recover from an enterprise - wide dos or destruction of critical system assets
  和企业范围的dos或关键系统资源被破坏相比，确定漏洞并在适当的位置采取经济实用的安全措施（例如灾难恢复计划以及日志备份系统）的代价要小得多。
