DDoS(Distributed Denial of Service) rudzi rwekurwiswa kwepaindaneti uko makomputa kana zvishandiso zvakawanda zvakakanganiswa zvinoshandiswa kuzadza system kana network nevanhu vakawanda, zvichikanganisa mashandiro ayo uye zvichikonzera kukanganiswa kwekushanda kwayo. Chinangwa chekurwiswa kweDDoS ndechekuita kuti system kana network isakwanise kushandiswa nevashandisi vepamutemo.
Heano mamwe mapoinzi makuru nezve kurwiswa kweDDoS:
1. Nzira yekurwisa: Kurwiswa kweDDoS kunowanzo sanganisira michina yakawanda, inozivikanwa sebotnet, iyo inodzorwa nemurwisi. Midziyo iyi inowanzo batwa ne malware inobvumira murwisi kudzora nekuronga kurwisa ari kure.
2. Mhando dzeDDoS Attacks: Kurwiswa kweDDoS kunogona kutora nzira dzakasiyana, kusanganisira kurwiswa kwehuwandu hunowedzera vanhu vanopinda panzvimbo yavanoda, kurwiswa kwe application layer kunonangana nema application kana masevhisi chaiwo, uye kurwiswa kweprotocol kunoshandisa kushaya simba muma network protocols.
3. Mhedzisiro: Kurwiswa kweDDoS kunogona kuva nemigumisiro yakaipa, zvichikonzera kukanganiswa kwebasa, nguva yekushanda, kurasikirwa nemari, kukuvara kwemukurumbira, uye kukanganisa ruzivo rwevashandisi. Zvinogona kukanganisa masangano akasiyana-siyana, anosanganisira mawebhusaiti, masevhisi epamhepo, mapuratifomu e-commerce, masangano emari, uye kunyange network dzese.
4. Kuderedza njodzi: Masangano anoshandisa nzira dzakasiyana-siyana dzekudzivirira DDoS kuchengetedza masisitimu avo nema network. Izvi zvinosanganisira kusefa traffic, kuderedza mwero we data, kuona zvinhu zvisina kujairika, kutsausa traffic, uye kushandisa hardware kana software yakagadzirirwa kuona nekuderedza kurwiswa kweDDoS.
5. Kudzivirira: Kudzivirira kurwiswa kweDDoS kunoda nzira yekukurumidza inosanganisira kushandisa matanho akasimba ekuchengetedza network, kuita ongororo dzenjodzi nguva dzose, kugadzirisa zvikanganiso zvesoftware, uye kuva nehurongwa hwekugadzirisa zviitiko kuti ubate kurwiswa zvinobudirira.
Zvakakosha kuti masangano arambe akangwarira uye agadzirire kupindura kurwiswa kweDDoS, sezvo zvichigona kukanganisa mashandiro ebhizinesi uye kuvimba nevatengi.
Kurwiswa kweDziviriro yeAnti-DDoS
1. Sefa mabasa asina basa uye maports
Inexpress, Express, Forwarding nezvimwe zvishandiso zvinogona kushandiswa kusefa mabasa asina basa uye maports, kureva kuti, kusefa ip yenhema pa router.
2. Kuchenesa nekusefa kuyerera kusina kujairika
Chenesa uye sefa traffic isina kujairika kuburikidza neDDoS hardware firewall, uye shandisa matekinoroji epamusoro akadai sekusefa mitemo yedata packet, kusefa data flow fingerprint detection, uye kusefa data packet content customization kuti uone nemazvo kana traffic yekunze iri yakajairika, uye kurambidza kusefa traffic isina kujairika.
3. Kudzivirirwa kwemapoka akapararira
Iyi ndiyo nzira inoshanda zvakanyanya yekudzivirira nharaunda yekuchengetedzwa kwemakombiyuta kubva mukurwiswa kukuru kweDDoS. Kana node ikarwiswa uye isingakwanise kupa masevhisi, sisitimu inozochinja otomatiki kuenda kune imwe node zvichienderana nehurongwa hwekutanga, uye inodzosera mapaketi ese edata emurwisi panzvimbo yekutumira, zvichikanganisa kwakabva kurwiswa uye zvichikanganisa bhizinesi kubva pakuona zvakadzama kwekuchengetedzwa kwekuchengetedza sarudzo dzekushandisa kuchengetedzwa.
4. Kuongororwa kweDNS kwakangwara kwakachengeteka
Musanganiswa wakakwana wehurongwa hwekugadzirisa DNS hwakangwara uye hurongwa hwekudzivirira hweDDoS hunopa mabhizinesi kugona kwakanyanya kwekuona njodzi dzekuchengetedza dziri kubuda. Panguva imwe chete, kunewo basa rekuona shutdown, iro rinogona kudzima server IP intelligence chero nguva kuti ritsive iyo yakajairika server IP, kuitira kuti network yebhizinesi igone kuchengetedza mamiriro ebasa risingaperi.
Kurwisa DDoS Kuchengetedza Bank Financial Network Kutarisira, Kuona & Kuchenesa Traffic:
1. Mhinduro yeNanosecond, inokurumidza uye yakarurama. Kuzvidzidzira kwebhizinesi uye tekinoroji yekuona kudzika kwepaketi zvinotorwa. Kana traffic isina kujairika uye meseji zvawanikwa, nzira yekudzivirira inotangwa kuti ive nechokwadi chekuti kunonoka pakati pekurwisa nekudzivirira kuri pasi pemasekondi maviri. Panguva imwe chete, mhinduro yekuchenesa kuyerera kusina kujairika yakavakirwa pamatanho epfungwa dzekuchenesa mafirita, kuburikidza nematanho manomwe ekugadzirisa kuongorora kuyerera, kubva mukurumbira weIP, nhanho yekufambisa uye nhanho yekushandisa, kuzivikanwa kwezvimiro, chikamu muzvikamu zvinomwe, maitiro enetwork, kuumbwa kwetraffic kudzivirira kusvina kuzivikanwa nhanho nenhanho, kuvandudza mashandiro ese ekudzivirira, vimbiso inoshanda yekuchengetedzwa kwenetwork yeXXX bank data center.
2. Kupatsanurwa kwekuongorora nekudzora, kunoshanda uye kwakavimbika. Hurongwa hwakasiyana hwekuisa nzvimbo yekuyedza nenzvimbo yekuchenesa hunogona kuita kuti nzvimbo yekuyedza irambe ichishanda mushure mekukundikana kwenzvimbo yekuchenesa, uye kugadzira mushumo wekuyedza uye chiziviso chealamu munguva chaiyo, izvo zvinogona kuratidza kurwiswa kwebhanga reXXX zvakanyanya.
3. Kutarisira kunochinjika, kuwedzera kusina kunetseka. Mhinduro yeAnti-ddos inogona kusarudza nzira nhatu dzekutarisira: kuona pasina kuchenesa, kudzivirira otomatiki uye kuchenesa, uye dziviriro yekubatana nemaoko. Kushandiswa kunochinjika kwenzira nhatu dzekutarisira kunogona kusangana nezvinodiwa nebhizinesi reXXX bank kuderedza njodzi yekushanda uye kuvandudza kuwanikwa kana bhizinesi idzva ratangwa.
Kukosha kweMutengi
1. Shandisa zvinobudirira network bandwidth kuti uvandudze mabhenefiti ebhizinesi
Kuburikidza nemhinduro yese yekuchengetedza, tsaona yekuchengetedza network yakakonzerwa nekurwiswa kweDDoS pabhizinesi repamhepo renzvimbo yayo yedata yaive 0, uye kutambisa bandwidth yekubuda kwenetwork kwakakonzerwa netraffic isina kunaka uye kushandiswa kwezviwanikwa zveseva kwakaderedzwa, izvo zvakaita kuti XXX bank ivandudze mabhenefiti ayo.
2. Deredza Njodzi, vimbisa kugadzikana kwenetwork uye kuchengetedzeka kwebhizinesi
Kushandiswa kwezvishandiso zve anti-ddos nenzira ye bypass hakuchinje magadzirirwo enetwork aripo, hapana njodzi yekubviswa kwenetwork, hapana kana poindi imwe chete yekukundikana, hapana kukanganisa mashandiro ebhizinesi, uye kunoderedza mari yekushandisa uye mari yekushandisa.
3. Kuvandudza kugutsikana kwevashandisi, kubatanidza vashandisi varipo uye kugadzira vashandisi vatsva
Kupa vashandisi nzvimbo chaiyo ye network, online banking, online business inquiries uye kumwe kugutsikana kwevashandisi ve online business kwave nani zvikuru, simbisa kuvimbika kwevashandisi, kupa vatengi masevhisi chaiwo.
