Ako va\u0161 sajt ima politi\u010dki karakter, prima uplate putem Interneta ili ako vodite profitabilan posao \u2013 DDoS napad<\/strong> mo\u017ee se dogoditi u bilo kojem trenutku. S engleskog, akronim DDoS prevodi se kao \"distribuirani napad za uskra\u0107ivanje usluge\". I za\u0161tita web servera od DDoS napada<\/a> najva\u017eniji je deo kvalitetnog hostinga.<\/p>\n

Jednostavno re\u010deno, DDoS napad<\/strong> to je preoptere\u0107enje servera kako ne bi mogao opslu\u017eiti posetitelje. Hakeri preuzimaju ra\u010dunarstvo u mre\u017ei i \u0161alju na ciljani server ogromnu koli\u010dinu praznih zahteva. Veli\u010dina botneta mo\u017ee varirati od nekoliko desetaka do nekoliko stotina hiljada ra\u010dunara. Server je primoran da odgovori na sve zahteve, ne mo\u017ee podneti optere\u0107enje i pada.<\/p>\n

Sistemi za\u0161tite servera od DDoS napada<\/h2>\n

Borba protiv DDoS napada<\/strong> mora se obavljati hardverskim metodama. Za to se na servernu opremu povezuju vatrozidi koji odlu\u010duju da li \u0107e propu\u0161tati saobra\u0107aj dalje. U njihovom firmware-u su zapisani algoritmi koji prepoznaju ve\u0107inu napada. Ako snaga napada ne prelazi zadate vrednosti u sertifikaciji, oprema \u0107e raditi u normalnom re\u017eimu. Nedostatak je ograni\u010dena propusnost i te\u0161ko\u0107e u preraspodeli saobra\u0107aja.<\/p>\n

Popularniji pristup<\/strong> je kori\u0161\u0107enje filtriraju\u0107e mre\u017ee. Po\u0161to se saobra\u0107aj generi\u0161e botnjetom, upotreba brojnih ra\u010dunara za borbu protiv praznog saobra\u0107aja je optimalno re\u0161enje. Mre\u017ea preuzima na sebe saobra\u0107aj, filtrira ga i do ciljanog servera dolazi samo provereni i kvalitetan saobra\u0107aj od stvarnih korisnika. Glavna prednost ovog pristupa je mogu\u0107nost fleksibilnog pode\u0161avanja za\u0161tite. Napredni hakeri su ve\u0107 nau\u010dili da \u0161tetni saobra\u0107aj maskiraju kao saobra\u0107aj obi\u010dnih posetilaca. Samo iskusni stru\u010dnjak za informati\u010dku za\u0161titu mo\u017ee da prepozna lo\u0161 saobra\u0107aj.<\/p>\n

Za za\u0161titu od takvih napada, provajderi i kompanije za hosting stvaraju mre\u017ee koje propu\u0161taju kroz sebe saobra\u0107aj i filtriraju ga. U ekstremnim slu\u010dajevima mogu\u0107e je povezivanje sa spoljim nodovima za pro\u010di\u0161\u0107avanje saobra\u0107aja.<\/p>\n

Arhitektura mre\u017ee sastoji se od tri sloja: usmjeravanja, sloja obrade paketa i sloja aplikacija. Na razini usmjeravanja dolazi do ravnomjerne raspodjele prometa me\u0111u \u010dvorovima mre\u017ee zahvaljuju\u0107i visoko performantnim usmjeriva\u010dima. Na razini obrade paketa nekoliko me\u0111usobno rezerviranih ure\u0111aja filtrira dolazni promet prema posebnim algoritmima. Na razini aplikacija odvija se \u0161ifriranje, de\u0161ifriranje i obrada zahtjeva. Ako je potrebno, mo\u017eete pro\u010ditati izvje\u0161taje o kapacitetu i trajanju napada, kao i izvje\u0161taje o \u010di\u0161\u0107enju.<\/p>\n
