拒絕服務攻擊(Denial of Service Attack,簡稱DoS攻擊)是一種通過耗盡目标系統資源(如帶寬、計算能力或内存)使其無法正常提供服務的網絡攻擊手段。攻擊者通常通過發送大量無效請求、惡意數據包或利用系統漏洞,導緻合法用戶無法訪問服務器、網站或網絡設備。
在技術實現上,分布式拒絕服務攻擊(DDoS)是DoS攻擊的進階形式,攻擊者通過控制多個被感染的設備(如僵屍網絡)同時向目标發起攻擊,顯著增強破壞力。例如,2020年亞馬遜AWS曾遭受高達2.3 Tbps的DDoS攻擊,創下流量規模紀錄。
這類攻擊的危害主要體現在三個方面:
防禦措施通常采用多層防護體系,包括流量清洗、行為分析算法和Anycast網絡分發技術。美國國家标準與技術研究院(NIST)在《網絡安全框架》中建議,關鍵系統應部署基于機器學習的異常流量檢測系統。企業可通過内容分發網絡(CDN)和Web應用防火牆(WAF)緩解攻擊影響。
拒絕服務攻擊(Denial of Service Attack,簡稱DoS攻擊)是一種通過消耗目标系統資源或利用協議漏洞,使其無法正常提供服務的網絡攻擊方式。以下是詳細解釋:
DoS攻擊通過向目标服務器發送大量無效請求或惡意數據包,耗盡網絡帶寬、内存、CPU等資源,或觸發系統漏洞,導緻合法用戶無法訪問服務。例如,攻擊者可能利用TCP協議漏洞(如SYN Flood攻擊)使服務器陷入未完成連接的等待狀态,最終資源耗盡。
DoS通常由單一攻擊源發起,而DDoS(分布式拒絕服務攻擊)通過控制全球分布的“僵屍網絡”發起更大規模攻擊。例如,DDoS可能同時操控數千台設備向目标發送請求。
