DDoS je na\u010din napada na web stranicu kojim se onemogu\u0107ava pristup stvarnim korisnicima. Na primjer, ako je bankovna stranica dizajnirana za usluge 2000 ljudi istovremeno, haker \u0161alje 20.000 paketa u sekundi na uslu\u017eni server. Naravno, kanal \u0107e se preopteretiti i web stranica banke prestat \u0107e pru\u017eati usluge korisnicima. Stoga se postavlja pitanje: \u201e<a rel=\"nofollow\" href=\"\/hr\/zhashchita-ot-ddos\/\">Kako za\u0161tititi server od DDoS napada<\/a>?\u00bb.<\/p>\n<p>Za po\u010detak, potrebno je razumjeti da su za uspje\u0161nu provedbu napada potrebne ogromne ra\u010dunalne snage. Obi\u010dni ra\u010dunalo, kao ni kanal pru\u017eatelja usluga hakera, ne\u0107e mo\u0107i podnijeti optere\u0107enje. Za to se koristi botnet - mre\u017ea hakiranih ra\u010dunala koja provode napad. Trenutno se naj\u010de\u0161\u0107e u napadima primje\u0107uju IoT mre\u017ee \u2013 Internet stvari. To su hakirani sustavi \"Pametne ku\u0107e\" \u2014 ure\u0111aji povezani na internet. Sustavi alarmiranja, video nadzora, ventilacije i jo\u0161 mnogo toga.<\/p>\n<p>Stoga je va\u017eno razumjeti da se ozbiljan DDoS napad ne mo\u017ee odbiti samostalno. Mre\u017ena oprema, kao i sam server, jednostavno ne\u0107e izdr\u017eati snagu ovog napada, ne\u0107e stignuti filtrirati promet i \u201epasti\u201c \u0107e. U to vrijeme stvarni korisnici ne\u0107e mo\u0107i pristupiti web stranici, a poslovna reputacija tvrtke koja ne mo\u017ee organizirati rad svoje web stranice bit \u0107e naru\u0161ena.<\/p>\n<p>I to nije sve. Tra\u017eilice, zabrinute zbog nedostatka web stranice u indeksu, smanjit \u0107e njezinu poziciju u pretra\u017eivanju. Oporavak od tog gubitka mo\u017ee potrajati do mjesec dana. A za velike tvrtke to je gotovo smrt. To zna\u010di ili velike gubitke, ili \u010dak bankrot. Stoga nije razborito zanemariti za\u0161titu od DDoS napada.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5184\" src=\"https:\/\/prohoster.info\/wp-content\/uploads\/2017\/09\/kak-zashchitit-server-ot-ddos-atak.png\" alt=\"\" width=\"654\" height=\"352\" \/><\/p>\n<p>Postoje 4 metoda za\u0161tite od DDoS napada:<\/p>\n<ul style=\"list-style-image: url('https:\/\/prohoster.info\/wp-content\/uploads\/check\/check_server.png');\">\n<li><strong>Samostalna za\u0161tita.<\/strong> Pisanje skripti ili kori\u0161tenje vatrozida.
