Prema statistikama, oko polovice web stranica je u posljednjih godinu dana barem jednom bila izlo\u017eena DDoS napadima. U tu polovinu spadaju ne samo slabo posje\u0107eni blogovi novaka, ve\u0107 i ozbiljne web stranice e-trgovine ili resursi koji oblikuju javno mnijenje. Ako ne osigurate za\u0161titu servera od botova i neovla\u0161tenog pristupa \u2013 o\u010dekujte ozbiljne gubitke, pa \u010dak i prestanak poslovanja. Tvrtka ProHoster<\/a> nudi Vam da za\u0161titite svoj projekt s visokom optere\u0107enjem od zlonamjernih napada.<\/p>\n

DDoS napad je napad hakera na sustav. Cilj je dovesti ga do kvara. Oni \u0161alju na web stranicu mno\u0161tvo podataka koji server obra\u0111uje i koji se potom zamrzne. Tu su i enkriptirane veze, kao i veliki ili nepotpuni paketi podataka s razli\u010ditih IP adresa<\/a>. Broj ra\u010dunala u bot mre\u017ei mo\u017ee se mjeriti desecima i stotinama tisu\u0107a. Jedan u polju nije ratnik \u2013 boriti se protiv takve vojske samotna osoba jednostavno je nerealno.<\/p>\n

Motivi takvih postupaka mogu biti razli\u010diti \u2013 zavist, narud\u017eba konkurencije, politi\u010dka borba, \u017eelja za afirmacijom ili trening. Jasno je samo jedno \u2013 potrebna je za\u0161tita od ovog fenomena. A najbolja za\u0161tita je naru\u010divanje usluge \"Za\u0161tita servera od DDoS napada\" od hosting tvrtke.<\/p>\n

Svake godine je sve lak\u0161e i jeftinije izvesti DDoS napade. Alati napada\u010da se usavr\u0161avaju, a razina njihove organizacije zbunjuje \u010dak i stru\u010dnjake koji su vidjeli sve. Nevinosti \u0161kolaraca postupno se pretvaraju u ozbiljan kriminal uz pa\u017eljivu pripremu. To je na\u010din da se dovede sustav do kvara, bez ostavljanja pravnih dokaza. Nije ni \u010dudo da takvi napadi iz godine u godinu stje\u010du popularnost.<\/p>\n

Za\u0161tita servera od napada<\/h2>\n

Va\u017eno je napomenuti da ve\u0107inu DDoS napada sprovode dobro organizirani timovi hakera. No, na\u0161i pametni filtri mre\u017ea za pro\u010di\u0161\u0107avanje prometa od botova omogu\u0107it \u0107e filtriranje 90% zlonamjernog prometa i zna\u010dajno smanjiti optere\u0107enje na serveru. To je mogu\u0107e zahvaljuju\u0107i kori\u0161tenju cloud tehnologija. Mre\u017ea za filtriranje prometa sastoji se od mo\u0107nih usmjeriva\u010da i radnih ma\u0161ina koje presre\u0107u promet, ravnomjerno ga raspore\u0111uju me\u0111u sobom, filtriraju te \u0161alju na server. Za krajnjeg korisnika to mo\u017ee zna\u010diti malu latenciju u brzini u\u010ditavanja stranice, ali barem \u0107e mo\u0107i koristiti web stranicu.<\/p>\n

Slabi napadi do 10 Gbit\/s<\/strong> uklju\u010deni su u osnovni paket bilo kojeg hostinga. To zna\u010di da ih provodi neiskusni korisnik i ne donose veliku \u0161tetu. No, ako je napad ozbiljniji - obavezno je uklju\u010diti vanjske resurse.<\/p>\n

Za\u0161titit \u0107emo va\u0161 resurs od DDoS, SQL\/SSI Injection, Brute Force, Cross-site Scripting, XSS, Buffer Overflow, Directory Indexing zahvaljuju\u0107i kori\u0161tenju WAF (Web Applications Firewall). \u0160teta od DDoS napada nanosi ozbiljniju \u0161tetu poslovanju nego tro\u0161ak najskupljeg paketa za\u0161tite. Obratite se tvrtki ProHoster<\/a> ve\u0107 sada, i u\u010dinit \u0107emo va\u0161e poslovanje na mre\u017ei neprobojnim.<\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
