Om man ska tro p\u00e5 statistiken har omkring h\u00e4lften av alla webbplatser under det senaste \u00e5ret utsatts f\u00f6r DDoS-attacker \u00e5tminstone en g\u00e5ng. I denna h\u00e4lft ing\u00e5r inte bara svagtrafikerade nyb\u00f6rjarbloggar utan \u00e4ven seri\u00f6sa e-handelswebbplatser och plattformar som formar den offentliga opinionen. Utan skydd f\u00f6r servrar mot bots och obeh\u00f6rig \u00e5tkomst kan man r\u00e4kna med stora f\u00f6rluster eller till och med att verksamheten upph\u00f6r. ProHoster<\/a> erbjuder dig att skydda ditt h\u00f6gbelastade projekt fr\u00e5n skadliga attacker.<\/p>\n

DDoS-attack \u00e4r en attack fr\u00e5n hackare mot systemet. M\u00e5let \u00e4r att f\u00e5 systemet att krascha. De skickar en m\u00e4ngd data till webbplatsen, vilket servern m\u00e5ste bearbeta och d\u00e4rmed h\u00e4nger sig. Detta inkluderar b\u00e5de krypterade anslutningar samt stora eller ofullst\u00e4ndiga datapaketer fr\u00e5n olika IP-adresser<\/a>. Antalet datorer i botn\u00e4tet kan uppg\u00e5 till tiotusentals eller hundratusentals. En ensam k\u00e4mpe \u00e4r v\u00e4rdel\u00f6s \u2013 det \u00e4r om\u00f6jligt att k\u00e4mpa mot en s\u00e5 stor arm\u00e9 ensam.<\/p>\n

Motiven bakom s\u00e5dana handlingar kan vara olika \u2013 svartsjuka, uppdrag fr\u00e5n konkurrenter, politisk kamp, en \u00f6nskan att bevisa sig sj\u00e4lv eller tr\u00e4ningssyften. Det \u00e4r klart att det beh\u00f6vs skydd mot detta fenomen. Den b\u00e4sta skyddet \u00e4r att best\u00e4lla en tj\u00e4nst f\u00f6r \"Skydd av servrar mot DDoS-attacker\" fr\u00e5n ett webbhotell.<\/p>\n

\u00c5r efter \u00e5r blir det enklare och billigare att genomf\u00f6ra DDoS-attacker. Verktygen som angriparna anv\u00e4nder utvecklas, och deras organisationsniv\u00e5 f\u00f6rbluffar till och med erfarna specialister. Skolungdomars spratt h\u00e5ller p\u00e5 att f\u00f6rvandlas till seri\u00f6s kriminalitet med noggrant f\u00f6rberedda attacker. Det \u00e4r ett s\u00e4tt att f\u00e5 systemet att krascha utan att l\u00e4mna juridiskt bevisbara sp\u00e5r. Inte konstigt att s\u00e5dana attacker \u00f6kar i popularitet \u00e5r efter \u00e5r.<\/p>\n

Skydd av servrar mot attacker<\/h2>\n

Det \u00e4r v\u00e4rt att n\u00e4mna att en \u00f6verv\u00e4ldigande majoritet av DDoS-attacker utf\u00f6rs av v\u00e4lorganiserade hackergrupper. Men v\u00e5ra smarta filtreringssystem f\u00f6r borttagning av bottrafik kan filtrera bort 90 % av den skadliga trafiken och avsev\u00e4rt minska belastningen p\u00e5 servern. Detta \u00e4r m\u00f6jligt tack vare anv\u00e4ndningen av molnteknologier. Systemet f\u00f6r trafikfiltrering best\u00e5r av kraftfulla routrar och servrar som f\u00e5ngar upp trafiken, j\u00e4mnt f\u00f6rdelar den mellan sig, filtrerar och skickar den vidare till servern. F\u00f6r den slutgiltiga anv\u00e4ndaren kan detta inneb\u00e4ra en liten f\u00f6rdr\u00f6jning i sidladdningstiden, men han eller hon kommer \u00e5tminstone kunna anv\u00e4nda webbplatsen.<\/p>\n

Svaga attacker upp till 10 Gbit\/s<\/strong> ing\u00e5r i grundpaketet f\u00f6r alla webbhotell. Detta inneb\u00e4r att de utf\u00f6rs av en oerfaren anv\u00e4ndare och inte orsakar mycket skada. Men om attacken \u00e4r mer allvarlig m\u00e5ste man absolut ansluta externa resurser.<\/p>\n

Skadorna fr\u00e5n en DDoS-attack orsakar mer allvarlig skada f\u00f6r aff\u00e4rerna \u00e4n kostnaden f\u00f6r det dyraste skyddspaketet.
