Kui teie veebisait on poliitilise iseloomuga, aktsepteerib veebimakseid v\u00f5i kui teete kasumlikku \u00e4ri \u2013 DDoS-r\u00fcnnak<\/strong> v\u00f5ib toimuda igal ajal.

Ja veebiserveri kaitsmine DDoS-r\u00fcnnakute eest<\/a> on kvaliteetse hostingu k\u00f5ige olulisem osa.<\/p>\n

Lihtsalt \u00f6eldes, DDoS-r\u00fcnnak<\/strong> on see serveri \u00fclekoormamine, nii et see ei suuda k\u00fclastajaid teenindada. H\u00e4kkerid vallutavad arvutiv\u00f5rgu ja saadavad sihtserverisse tohutult t\u00fchje p\u00e4ringuid. Botneti suurus v\u00f5ib ulatuda paarik\u00fcmnest kuni mitme sadakuni arvutini. Server peab k\u00f5igile p\u00e4ringutele vastama, kuid ei suuda koormusega toime tulla ja kukub.<\/p>\n

DDoS-r\u00fcnnakute eest kaitsvad serveris\u00fcsteemid<\/h2>\n

Kuidas v\u00f5idelda DDoS-r\u00fcnnakutega<\/strong> Riistvara meetodid on v\u00f5imalikud. Selleks \u00fchendatakse serveri varustus tulekahjusid, mis otsustavad, kas lasta liiklus edasi. Nende tarkvaras on kirjutatud algoritmid, mis tuvastavad enamus r\u00fcnnakuid. Kui r\u00fcnnaku j\u00f5ud ei \u00fcleta sertifitseerimises m\u00e4\u00e4ratud v\u00e4\u00e4rtusi, t\u00f6\u00f6tab seadmed tavalises re\u017eiimis. Puuduseks on piiratud ribalaius ja raskused liikluse \u00fcmbersuunamisel.<\/p>\n

Populaarsem l\u00e4henemine<\/strong> on filtreerimisv\u00f5rgu kasutamine. Kuna liiklus genereeritakse botiv\u00f5rgu poolt, on paljude arvutite kasutamine t\u00fchja liikluse vastu v\u00f5itlemiseks k\u00f5ige optimaalsem lahendus. V\u00f5rk v\u00f5tab liikluse enda peale, filtreerib selle ning sihtserverisse j\u00f5uab vaid kontrollitud ja kvaliteetne liiklus t\u00f5elistelt kasutajatelt. Selle l\u00e4henemise peamine eelis on paindlik kaitse seadistamine. Edasij\u00f5udnud h\u00e4kkerid on juba \u00f5ppinud kahjuliku liikluse varjama tavaliste k\u00fclastajate liikluse alla. Halva liikluse oskab \u00e4ra tunda vaid kogenud infokaitse spetsialist.<\/p>\n

Agressioonide kaitsmiseks loovad teenusepakkujad ja veebihostingufirmad v\u00f5rgud, mis suunavad kaudu liiklust ja filtreerivad seda. \u00c4\u00e4rmuslikel juhtudel on v\u00f5imalik liituda kolmandate osapoolte liikluse puhastamise s\u00f5lmedega.<\/p>\n

V\u00f5rgu arhitektuur koosneb kolmest kihist: marsruutimisest, paketi t\u00f6\u00f6tlemise kihist ja rakenduste kihist. Marsruutimise tasandil jaotatakse voog v\u00f5rgu s\u00f5lmede vahel \u00fchtlaselt t\u00e4nu \u00fcliv\u00f5imsatele marsruutijatele. Paketi t\u00f6\u00f6tlemise tasandil filtreerivad mitmed omavahel reservatsiooniga seadmed sissetulevat liiklust spetsiaalsete algoritmide j\u00e4rgi. Rakenduste tasandil toimub kr\u00fcpteerimine, dekr\u00fcpteerimine ja p\u00e4ringute t\u00f6\u00f6tlemine. Vajadusel on v\u00f5imalik lugeda r\u00fcnnakute tugevuse ja kestuse aruandeid ning ka puhastamise aruandeid.<\/p>\n
