DDoS predstavlja na\u010din napada na spletno stran, s katerim se prepre\u010di dostop resni\u010dnim uporabnikom. Na primer, \u010de je spletna stran banke zasnovana za obravnavo 2000 oseb hkrati, heker po\u0161lje 20.000 paketov na sekund do stre\u017enika. Seveda bo povezava preobremenjena in spletna stran banke ne bo mogla ve\u010d obravnavati strank. Zaradi tega se postavlja vpra\u0161anje: \"<a rel=\"nofollow\" href=\"\/sl\/zhashchita-ot-ddos\/\">Kako za\u0161\u010dititi stre\u017enik pred DDoS napadi<\/a>?\u00bb.<\/p>\n<p>Za za\u010detek je treba razumeti, da za uspe\u0161en napad potrebujemo ogromne ra\u010dunalni\u0161ke zmogljivosti. Navaden ra\u010dunalnik, prav tako kot povezava hekerskega ponudnika, ne bo mogel obvladovati obremenitev. Zato se uporablja botnet - mre\u017ea oku\u017eenih ra\u010dunalnikov, ki izvajajo napad. Trenutno so v napadih najpogosteje opa\u017eene IoT mre\u017ee - internet stvari. To so oku\u017eeni sistemi \"Pametnega doma\" \u2014 naprave, povezane z internetom. Sistemi za alarmiranje, video nadzor, prezra\u010devanje in \u0161e ve\u010d.<\/p>\n<p>Zato je pomembno razumeti, da resne DDoS napade nemogo\u010de odbiti samostojno. Omre\u017ena oprema, kot tudi sam stre\u017enik, preprosto ne bosta zdr\u017eala mo\u010di napada, hitrost filtrovnega prometa pa ne bo dovolj in 'spustila' se bo. Resni\u010dni uporabniki v tem \u010dasu ne bodo mogli dostopati do spletne strani, in poslovna reputacija podjetja, ki ne more organizirati delovanja svoje spletne strani, bo ogro\u017eena.<\/p>\n<p>In to \u0161e ni vse. Iskalniki, ki so zaskrbljeni zaradi odsotnosti spletne strani v indeksu, bodo zni\u017eali njene pozicije v iskanju. Obnovitev izvornih pozicij lahko traja do enega meseca. Za velika podjetja je to enako smrti. To pomeni bodisi velike izgube bodisi celo bankrot. Zato ne smete zanemariti za\u0161\u010dite pred DDoS napadi.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5184\" src=\"https:\/\/prohoster.info\/wp-content\/uploads\/2017\/09\/kak-zashchitit-server-ot-ddos-atak.png\" alt=\"\" width=\"654\" height=\"352\" \/><\/p>\n<p>Obstajajo 4 na\u010dini za\u0161\u010dite pred DDoS napadi:<\/p>\n<ul style=\"list-style-image: url('https:\/\/prohoster.info\/wp-content\/uploads\/check\/check_server.png');\">\n<li><strong>Samostojna za\u0161\u010dita.<\/strong> Pisanje skript ali uporaba po\u017earnega zidu.
