Kui teie veebileht on poliitilise olemusega, aktsepteerib internetimakseid v\u00f5i kui teete kasumlikku \u00e4ri \u2013 DDoS-r\u00fcnnak<\/strong> v\u00f5ib toimuda igal hetkel. DDoS l\u00fchend inglise keeles t\u00e4hendab 'jaotatud teenuse keelamise r\u00fcnnakut'. Ja veebiserveri kaitsmine DDoS-r\u00fcnnakute eest<\/a> on kvaliteetse hostimise k\u00f5ige olulisem osa.<\/p>\n

Lihtsalt \u00f6eldes, DDoS-r\u00fcnnak<\/strong> on see serveri koormamine, et see ei saaks k\u00fclastajaid teenindada. H\u00e4kkerid vallutavad arvutiv\u00f5rgu ja saadavad sihitud serverisse tohutul hulgal t\u00fchje p\u00e4ringuid. Botiv\u00f5rgu suurus v\u00f5ib ulatuda mitmest k\u00fcmnest kuni mitme saja tuhande arvutini. Server peab vastama k\u00f5igile p\u00e4ringutele, kuid ei suuda koormust taluda ja kokku kukub.<\/p>\n

Serverite kaitses\u00fcsteemid DDoS-r\u00fcnnakute vastu<\/h2>\n

DDoS-r\u00fcnnakutega<\/strong> saab v\u00f5idelda riistvaraliste meetoditega. Selleks \u00fchendatakse serverivarustusse tulem\u00fc\u00fcrid, mis otsustavad, kas lasta liiklus edasi. Nende t\u00f6\u00f6keskkonnas on m\u00e4\u00e4ratud algoritmid, mis tuvastavad enamikku r\u00fcnnakutest. Kui r\u00fcnnaku intensiivsus ei \u00fcleta sertifitseerimisel kehtivaid v\u00e4\u00e4rtusi, t\u00f6\u00f6tab varustus tavare\u017eiimis. Puuduseks on piiratud l\u00e4bilaskev\u00f5ime ja raskused liikluse \u00fcmberjaotamisel.<\/p>\n

Populaarsem l\u00e4henemine<\/strong> on filtreerimise v\u00f5rgustiku kasutamine. Kuna liiklus genereeritakse botiv\u00f5rgust, on mitme arvuti kasutamine t\u00fchja liikluse vastu v\u00f5itlemiseks k\u00f5ige optimaalsem lahendus. V\u00f5rk v\u00f5tab liikluse enda peale, filtreerib selle ja sihtserverini j\u00f5uab vaid kontrollitud ning kvaliteetne liiklus reaalsetelt kasutajatelt. Selle l\u00e4henemise peamine eelis on kaitse paindlik seadistamine. Edasij\u00f5udnud h\u00e4kkerid on juba \u00f5ppinud kahjulikku liiklust peitma tavaliste k\u00fclastajate liikluse alla. Halba liiklust suudab tuvastada vaid kogenud infokaitse spetsialist.<\/p>\n

Selliste r\u00fcnnakute eest kaitsmiseks loovad teenusepakkujad ja hostimisfirmad v\u00f5rgud, mis suunavad liiklust enda kaudu ja filtreerivad selle. \u00c4\u00e4rmuslikel juhtudel on v\u00f5imalik \u00fchendada kolmandate osapoolte liikluse puhastamise s\u00f5lmedega.<\/p>\n

V\u00f5rguarhitektuur koosneb kolmest kihist: marsruutimisest, pakettide t\u00f6\u00f6tlemisest ja rakendusest. Marsruutimistasemel jaotatakse liiklus v\u00f5rgu s\u00f5lmede vahel \u00fchtlaselt \u00fclikiirete marsruuterite abil. Pakettide t\u00f6\u00f6tlemise tasemel filtreerivad mitmed omavahel broneeritavad seadmed sissetulevat liiklust spetsiaalsete algoritmide abil. Rakenduste tasemel toimub kr\u00fcptimine, dekodeerimine ja p\u00e4ringute t\u00f6\u00f6tlemine. Vajadusel saab lugeda r\u00fcnnakute v\u00f5imsuse ja kestuse aruandeid ning aruandeid puhastamise kohta.<\/p>\n
