國家能源局在2015年2月4日印發了《電力監控系統安全防護總體方案》(俗稱36號文),規定火力發電廠以機組大小進行等保定級工作,單機容量在300MW及以上為3級,以下為2級。各火力發電企業應該按此要求對電廠電力監控系統開展等保定級和安全防護建設工作。隨后《中華人民共和國網絡安全法》于2017年6月1日正式執行,對于火力發電機幸运飞艇彩之家組這類國家關鍵信息基礎設施,規定在等級保護的基礎上實行重點保護。

1、在DCS控制系統內部署入侵檢測系統,用于網絡內攻擊行為的檢測。入侵檢測系統很好的彌補了邊界隔離產品的不足,可有效監視交換機上的所有實時傳輸數據,提供全面專業入侵檢測能力,通過協議狀態檢查和智能關聯分析,為DCS系統用戶提供全面的信息展現和安全預警,為改善用戶網絡的風險控制環境提供決策依據,是整個網絡體系中不可或缺的一部分。
