هجمات حَجْب، إيقاف الخدمة |  Denial of Service attack DoS

08 مارس 2020


هجوم رقمي غير شرعي؛ لإيقاف الخدمات التي يقدمها حاسوب مُحدَّد، أو خادم، أو موقع حسب أهداف القرصان القائم بالهجوم؛ وهذا يمنع المستخدمين من الوصول إلى الخدمة، والاستفادة منها. يمكن إطلاق الهجوم من مصدر مُحدَّد، أو عبر نشر برمجية خبيثة، تنتشر، وتستخدم أجهزة كثيرة متصلة بالإنترنت؛ مما يجعل الهجوم أكثر قوة، وهو ما حدث عدة مرات في السنوات السابقة، وأوقف خدمات "أمازون" و"مايكروسوفت" بضع مرات.
