DDoS(Distributed Denial of Service) imhando yekurwiswa kwecyber apo makomputa akawanda akakanganiswa kana zvishandiso zvinoshandiswa kufashamira hurongwa kana network ine huwandu hukuru hwetraffic, ichiremedza zviwanikwa zvayo uye ichikonzera kukanganisa mukushanda kwayo. Chinangwa chekurwiswa kweDDoS ndechekuita kuti inotangwa system kana network isasvike kune vashandisi vari pamutemo.
Heano mamwe mapoinzi akakosha nezve DDoS kurwiswa:
1. Attack Method: DDoS kurwisa kunowanzobatanidza nhamba huru yemidziyo, inozivikanwa se botnet, iyo inotungamirirwa neanorwisa. Midziyo iyi inowanzotapukirwa nemalware inobvumira anorwisa kudzora kure uye kuronga kurwiswa.
2. Mhando dzeDDoS Inorwisa: DDoS kurwiswa kunogona kutora mafomu akasiyana, kusanganisira kurwiswa kwevolumetric kunofashamira chinangwa netraffic yakawandisa, kurwiswa kwedhizaini kunonangana nemashandisirwo chaiwo kana masevhisi, uye kurwiswa kweprotocol kunoshandisa kusadzivirirwa mumatiweki eprotocol.
3. Impact: DDoS kurwiswa kunogona kuve nemhedzisiro yakaipa, zvichikonzera kukanganisa kwesevhisi, kuderera, kurasikirwa kwemari, kukuvadzwa kwezita, uye kukanganisa ruzivo rwevashandisi. Zvinogona kukanganisa masangano akasiyana siyana, anosanganisira mawebhusaiti, masevhisi epamhepo, e-commerce mapuratifomu, masangano emari, uye kunyange network yese.
4. Mitigation: Masangano anoshandisa nzira dzakasiyana dzeDDoS dzekudzikisa kuchengetedza masisitimu avo uye network. Izvi zvinosanganisira kusefa kwetraffic, kudzikamisa chiyero, kutariswa kweanomaly, kuchinjika kwetraffic, uye kushandiswa kwehunyanzvi Hardware kana software mhinduro dzakagadzirirwa kuona uye kurerutsa DDoS kurwiswa.
5. Kudzivirira: Kudzivirira kurwiswa kweDDoS kunoda nzira inobatika inosanganisira kuita yakasimba network kuchengetedza matanho, kuita ongororo yekusagadzikana, kupeta kusashanda kwesoftware, uye kuve nehurongwa hwekupindura zviitiko munzvimbo yekubata kurwiswa nemazvo.
Zvakakosha kuti masangano agare akasvinura uye agadzirire kupindura kurwiswa kweDDoS, sezvo achigona kuita zvakakosha pamashandiro ebhizinesi uye kuvimba nevatengi.
Defence Anti-DDoS kurwisa
1. Sefa zvisina basa masevhisi uye zviteshi
Inexpress, Express, Forwarding uye mamwe maturusi anogona kushandiswa kusefa zvisina basa masevhisi uye zviteshi, kureva, kusefa ip yekunyepedzera pane router.
2. Kuchenesa nekusefa kwekuyerera kusina kujairika
Chenesa uye kusefa traffic isina kujairika kuburikidza neDDoS hardware firewall, uye shandisa yepamusoro-level tekinoroji senge data packet mutemo kusefa, kuyerera kwedhata kufefeta zvigunwe, uye data packet yemukati yekusefa kuti uone chaizvo kana yekunze yekupinda traffic yakajairika, uye inorambidza kusefa. yeabnormal traffic.
3. Yakaparadzirwa cluster kudzivirira
Iyi ndiyo nzira inonyanya kushanda yekudzivirira cybersecurity nharaunda kubva mukurwiswa kukuru kweDDoS. Kana node ikarwiswa uye isingakwanise kupa masevhisi, sisitimu yacho inongochinja ichienda kune imwe node zvinoenderana nekutanga kurongeka, uye inodzosera ese eanorwisa data mapaketi kunzvimbo yekutumira, kuremadza kwainobva kurwiswa uye kukanganisa bhizinesi kubva pakuchengetedza kwakadzika. kuchengetedza maonero ekuchengetedza sarudzo dzekuita.
4. Kuchengetedza kwepamusoro kwakachenjera DNS kuongorora
Iko kusanganiswa kwakakwana kwehungwaru DNS resolution system uye DDoS kudzivirira system inopa mabhizinesi ane super yekuona hunyanzvi hwekutyisidzira kuri kubuda. Panguva imwecheteyo, kunewo kuvharwa kwekuona basa, iyo inogona kudzima server IP intelligence chero nguva kutsiva yakajairika server IP, kuitira kuti bhizinesi network ichengetedze isingambomira sevhisi.
Anti DDoS Inorwisa yeBhangi Yemari Network Chengetedzo Yekutarisira Traffic, Kuona & Kuchenesa:
1. Mhinduro yeNanosecond, inokurumidza uye yakarurama.Business model traffic self-learning uye packet by packet deep yekuona teknolojia inogamuchirwa. Kana traffic isina kujairika uye meseji yawanikwa, iyo yekudzivirira yekukurumidza nzira inotangwa kuti ive nechokwadi chekuti kunonoka pakati pekurwisa nekudzivirira kuri pasi pemasekonzi maviri. Panguva imwecheteyo, iyo isina kujairika yekuyerera yekuchenesa mhinduro yakavakirwa pazvikamu zvesefa yekuchenesa chitima chepfungwa, kuburikidza neanomwe akaturikidzana ekuyerera kwekuongorora kugadzirisa, kubva kuIP mukurumbira, iyo yekufambisa layer uye application layer, kucherechedzwa kwechiitiko, chikamu muzvikamu zvinomwe, network. maitiro, iyo traffic kuumbwa kudzivirira kuzivikanwa kusefa nhanho nhanho, kunatsiridza kuita kwese kwedziviriro, inoshanda vimbiso yeXXX bank data center network kuchengetedza.
2. Kuparadzaniswa kwekuongorora uye kutonga, kushanda uye kuvimbika. Iyo yakaparadzana deployment scheme yetest centre nenzvimbo yekuchenesa inogona kuve nechokwadi chekuti bvunzo nzvimbo inogona kuramba ichishanda mushure mekutadza kwenzvimbo yekuchenesa, uye kuburitsa mushumo wekuyedza uye chiziviso chealarm munguva chaiyo, iyo inogona kuratidza kurwiswa kweXXX bank. kusvika pamwero mukuru.
3. Flexible manejimendi, kuwedzera kunetseka-isina.Anti-ddos mhinduro inogona kusarudza matatu manejimendi modes: kuona pasina kuchenesa, otomatiki kuona uye kuchenesa kudzivirira, uye manual interactive protection.Kushandiswa kunoshanduka kwemaitiro matatu ekutungamirira kunogona kusangana nebhizimisi zvinodiwa zveXXX bhangi kudzikisa njodzi yekushandisa uye kuvandudza kuwanikwa kana bhizinesi idzva rikatangwa.
Mutengi Kukosha
1. Shandisa zvinobudirira network bandwidth kuvandudza mabhenefiti ebhizinesi
Kuburikidza nemhinduro yese yekuchengetedza, tsaona yekuchengetedza network yakakonzerwa nekurwiswa kweDDoS bhizinesi repamhepo renzvimbo yayo yedata yaive 0, uye kutambisa network outlet bandwidth yakakonzerwa nekusashanda traffic uye kushandiswa kweserver zviwanikwa zvakaderedzwa, izvo zvakagadzira mamiriro eXXX. bhanga kuti rivandudze mabhenefiti ayo.
2. Deredza Njodzi, chengetedza kugadzikana kwetiweki uye kusimba kwebhizinesi
Iyo bypass deployment ye-anti-ddos michina haichinje iripo network architecture, hapana njodzi yetiweki cutover, hapana imwe pfungwa yekutadza, hapana kukanganisa pane yakajairika mashandiro ebhizinesi, uye inoderedza mutengo wekushandisa uye mutengo wekushandisa.
3. Kuvandudza kugutsikana kwevashandisi, simbisa vashandisi varipo uye gadzira vashandisi vatsva
Ipa vashandisi nzvimbo chaiyo yetiweki, kubhengi yepamhepo, kubvunza kwebhizinesi repamhepo uye kumwe kugutsikana kwevashandisi vepamhepo kwakagadziridzwa zvakanyanya, kusanganisa kuvimbika kwemushandisi, kupa vatengi masevhisi chaiwo.
