Zagro\u017cenia w internecie mog\u0105 przyjmowa\u0107 r\u00f3\u017cn\u0105 form\u0119. Jednym z nich jest atak DDOS. Czym w\u0142a\u015bciwie jest? \u00a0Czy jest gro\u017any i w jakich sytuacjach najcz\u0119\u015bciej si\u0119 pojawia?<\/p>\n

Atak DDOS \u2013 co to znaczy?<\/h2>\n

DDOS to skr\u00f3t od Distributed Denial of Service<\/em>, co mo\u017cna rozumie\u0107 jako rozproszon\u0105 odmow\u0119 dost\u0119pu<\/strong>. A czym jest atak DDOS? To atakowanie danego serwisu lub konta z kilku komputer\u00f3w jednocze\u015bnie w tym samym czasie<\/strong>. Jego konsekwencj\u0105 jest zablokowaniu dost\u0119pu do \u0142\u0105czy lub serwis\u00f3w internetowych<\/strong>.<\/p>\n

Sprawd\u017a te\u017c: Przeczytaj te\u017c: Najpopularniejsze zagro\u017cenia w internecie \u2013 zobacz, na co uwa\u017ca\u0107 >><\/a><\/p>\n

Jak przebiega atak DDOS?<\/h2>\n

Na okre\u015blony sygna\u0142 wiele komputer\u00f3w w tym samym czasie atakuje system operacyjny ofiary. Atak mo\u017ce wygl\u0105da\u0107 jak liczne odwiedziny na stronie i zasypywanie systemu fa\u0142szywymi pr\u00f3bami skorzystania z us\u0142ug<\/strong>, kt\u00f3re si\u0119 na nim znajduj\u0105. W rezultacie system komputerowy czy serwis przestaje dzia\u0142a\u0107, poniewa\u017c wszystkie jego wolne zasoby zostaj\u0105 zaj\u0119te w wyniku ataku wykonywanego przez wiele komputer\u00f3w jednocze\u015bnie.<\/p>\n

Strona odpowiada na \u017c\u0105dania, co wi\u0105\u017ce si\u0119 z czerpaniem z zasob\u00f3w, takich jak pami\u0119\u0107, czas procesora, pasmo sieciowe. Przy du\u017cej liczbie \u017c\u0105da\u0144 dochodzi do wyczerpania zasob\u00f3w i przerwy w\u00a0dzia\u0142aniu systemu lub ca\u0142kowitego zawieszenia<\/strong>.<\/p>\n

Z tego powodu atak DDOS jest szczeg\u00f3lnym zagro\u017ceniem dla serwis\u00f3w aukcyjnych czy firm brokerskich,<\/strong> dla kt\u00f3rych chwilowy lub d\u0142u\u017cszy brak dost\u0119pu do strony internetowej wi\u0105\u017ce si\u0119 ze znacznymi stratami finansowymi. Cz\u0119sto w wyniku ataku DDOS serwisy internetowe czy us\u0142ugi pocztowe mog\u0105 by\u0107 niewidoczne w internecie. Skutki ataku to nie tylko problemy techniczne i finansowe, ale tak\u017ce wizerunkowe<\/strong>.<\/p>\n
