美國對伊斯蘭國的網絡戰取得進展大綱

For months now, U.S. government hackers have been setting their sights on the Islamic State terror group, intent on wiping the self-declared caliphate from cyberspace much like U.S. and coalition aircraft have sought to wipe it from the face of the earth. Yet, some of those helping to lead the virtual charge admit it is not yet clear just how effective the cyber efforts have been.

Reinforcing the concerns is a sense, from both military and intelligence officials, that Islamic State may well prove to be as resilient and adaptable in the virtual battle space as it has been on the physical battlefield.

“It’s working well,” U.S. Director of National Intelligence James Clapper told an audience Wednesday during a speech in Washington, adding, “It’s kind of a work in progress.”

“I think we’re learning from this experience, having a real live operation,” he said. “As we progress further we’ll be able to make a more definitive assessment.”

U.S. officials have, so far, been careful in talking publicly about what U.S. cyber operations against Islamic State entail, though Defense Secretary Ash Carter said in late February a top priority would be “to interrupt, disrupt ISIL's command and control.”數月來，美國政府的黑客一直把注意力集中在伊斯蘭國恐怖組織身上，試圖將這個所謂“哈里發國”從網絡空間清除出去，就像美國及聯盟的戰機試圖消滅伊斯蘭國一樣。但一些參與人員承認，目前還不清楚這一網絡行動的有效性。

美國軍方和情報部門官員擔心，伊斯蘭國在網絡戰中可能也像在地面戰鬥中那樣，具有很強的恢復能力和適應性。

美國國家情報總監克拉珀星期三在華盛頓發表講話時說，目前這一行動有所進展。

他說，我們正在取得經驗，隨着進一步的推進，將能對情況做出更準確的評估。

到目前爲止，美國官員在公開談論針對伊斯蘭國的網絡行動時都很謹慎，但國防部長卡特2月底曾表示，首要任務是干擾和切斷伊斯蘭國的指揮和控制系統。
