Ak v\u00e1\u0161 web m\u00e1 politick\u00fd charakter, spracov\u00e1va platby cez internet alebo vediete ziskov\u00fd biznis - DDoS \u00fatok<\/strong> m\u00f4\u017ee nasta\u0165 kedyko\u013evek.

Jednoducho povedan\u00e9, DDoS \u00fatok<\/strong> je to pre\u0165a\u017eenie servera, aby nemohol obsluhova\u0165 n\u00e1v\u0161tevn\u00edkov.

Syst\u00e9my ochrany serverov pred DDoS \u00fatokmi<\/h2>\n

Boj proti DDoS \u00fatokom<\/strong> je mo\u017en\u00e9 aj hardv\u00e9rov\u00fdmi metodami. K serverov\u00e9mu zariadeniu sa prip\u00e1jaj\u00fa firewally, ktor\u00e9 rozhoduj\u00fa, \u010di \u010falej pusti\u0165 traffic. Vo ich firmv\u00e9ri s\u00fa zak\u00f3dovan\u00e9 algoritmy, ktor\u00e9 identifikuj\u00fa v\u00e4\u010d\u0161inu \u00fatokov. Ak v\u00fdkon \u00fatoku nepresahuje stanoven\u00e9 hodnoty v certifik\u00e1cii, zariadenie bude fungova\u0165 v norm\u00e1lnom re\u017eime. Nev\u00fdhodou je obmedzen\u00e1 \u0161\u00edrka p\u00e1sma a \u0165a\u017ekosti pri pres\u00favan\u00ed trafficu.<\/p>\n

Ob\u013e\u00fabenej\u0161\u00ed pr\u00edstup<\/strong> je pou\u017e\u00edvanie filtrovej siete. Ke\u010f\u017ee traffic je generovan\u00fd botnetom, pou\u017eitie viacer\u00fdch po\u010d\u00edta\u010dov v boji s pr\u00e1zdnym trafficom je optim\u00e1lne rie\u0161enie. Sie\u0165 preber\u00e1 traffic na seba, filtruje ho a na cie\u013eov\u00fd server sa dostane len overen\u00fd a kvalitn\u00fd traffic od skuto\u010dn\u00fdch pou\u017e\u00edvate\u013eov. Hlavnou v\u00fdhodou tohto pr\u00edstupu je flexibilita v nastaven\u00ed ochrany. Pokro\u010dil\u00ed hackeri sa u\u017e nau\u010dili maskova\u0165 \u0161kodliv\u00fd traffic ako traffic be\u017en\u00fdch n\u00e1v\u0161tevn\u00edkov. Rozpozna\u0165 zl\u00fd traffic je schopn\u00fd len sk\u00fasen\u00fd odborn\u00edk na ochranu inform\u00e1ci\u00ed.<\/p>\n

Na ochranu pred tak\u00fdmito \u00fatokmi poskytovatelia a hostingov\u00e9 spolo\u010dnosti vytv\u00e1raj\u00fa siete, ktor\u00e9 prech\u00e1dzaj\u00fa trafficom a filtruj\u00fa ho. V krajnom pr\u00edpade je mo\u017en\u00e9 pripojenie k extern\u00fdm uzlom na \u010distenie trafficu.<\/p>\n

Architekt\u00fara siete pozost\u00e1va z troch vrstiev: smerovania, vrstvy spracovania paketov a aplika\u010dnej vrstvy. Na \u00farovni smerovania doch\u00e1dza k rovnomern\u00e9mu rozdeleniu pr\u00fadu medzi uzlami siete v\u010faka v\u00fdkonn\u00fdm smerova\u010dom. Na \u00farovni spracovania paketov nieko\u013eko vz\u00e1jomne rezervovate\u013en\u00fdch zariaden\u00ed filtruje prich\u00e1dzaj\u00faci prenos pod\u013ea \u0161peci\u00e1lnych algoritmov. Na \u00farovni aplik\u00e1ci\u00ed sa vykon\u00e1va \u0161ifrovanie, de\u0161ifrovanie a spracovanie po\u017eiadaviek. V pr\u00edpade potreby je mo\u017en\u00e9 si pre\u010d\u00edta\u0165 spr\u00e1vy o v\u00fdkonoch a trvan\u00ed \u00fatokov, ako aj spr\u00e1vy o \u010disten\u00ed.<\/p>\n
