Ukhiye we-SSH ukhophiwe noma i-ejenti idlulisiwe? Izingozi ezimbili ezihlukene

Ukungena okusebenzisa ukhiye we-SSH nge-VPN akusho ukuthi ukhiye wangasese wanikezwa umqhubi wenethiwekhi, futhi leso siqinisekiso sincane kunalokho abantu abakuzwayo. Ukuqinisekiswa kokhiye womphakathi kuthumela ukhiye womphakathi kanye nesiginesha ekhiqizwa iklayenti endaweni. Ukudlulisela i-ejenti kuwukuhlelwa okuhlukile okunokuchayeka okuhlukile, futhi kungase kushiye ikhono lokuqinisekisa elisebenzisekayo emshinini ongawulawuli. Impendulo okufanele uyiphe incike ekutheni yikuphi kwalokhu okubili okwenzeka ngempela.

Ukuqinisekiswa kokhiye womphakathi kuthumelani

Endleleni evamile yokhiye womphakathi iklayenti linikela ukhiye womphakathi, iseva inquma ukuthi iyawamukela yini lowo khiye, futhi iklayenti lisayina inselelo ngokhiye wangasese, ohlala efayeleni laso noma ku-ejenti yaso. Okunqamula inethiwekhi ukhiye womphakathi kanye nesiginesha esivela kuwo. Akukho okukulo lokho kushintshana okudinga ukuthi iseva, ithumbu noma noma ubani endleleni aphethe impahla yangasese.

Incazelo yokuqinisekisa ichaza lobo bufakazi, futhi ukhiye wangasese akuyona inkambu esicelweni.

Lesi yisitatimende mayelana nephrothokholi, hhayi isitifiketi sokuziphatha sayo yonke indawo yokugcina ethintekayo. Ukuhlolwa kobunikazi bomsingathi kusafanele kuhlale kungonakalisiwe, ngoba iseva engakwazi ukufakazela ukuthi ingubani ingase iqoqe amasiginesha ngenjongo obengayihlosile. I-VM eqashiwe, i-bastion ezuzwe njengefa kanye nekhompyutha ephathekayo esebenzisa isengezo esingaziwa kuyimibuzo emithathu ehlukene yokuthembela. Bahlukanise nombuzo we-cryptographic, osekuxazululwe ngempela.

Ukudlulisela i-ejenti kunikeza ini igunya

Ukudlulisela i-ejenti kuvula umsele osuka kumsingathi okude ubuyela ku-ejenti emshinini wakho, ukuze izinqubo kuleyo msingathi zicele i-ejenti ukuthi isayine ngaphandle kokuphatha ukhiye wangasese. Ukhiye uhlala lapho ukhona, futhi ikhono alihlali. Noma yini engafinyelela kuleso sokhethi esidlulisiwe kumsingathi okude, isikhathi sonke somhlangano, ingacela imisebenzi yokuqinisekisa njengenye yobunikazi obulayishiwe. Lokho yigunya elithunyelwe, yingakho ukudlulisela kufanele kuthole inqubomgomo encane kunokunikeza ukhiye womphakathi.

Ifayela lokhiye elikhophiwe wukuvezwa. I-ejenti edlulisiwe yimvume, futhi kokubili kudinga izimpendulo ezihlukene.

Vula ukudlulisela ngesidingo esishiwo kanye nangemisingathi eshiwo, futhi uhlole okwenziwa iklayenti ngempela esikhundleni salokho okubonakala kusho ukuhlelwa. Okubalulekile izilungiselelo ezisebenzayo, ngoba ibhloko yomsingathi yeqa buthule okuhlosiwe komhlaba wonke. Umbono ofanayo usebenza ohlangothini lweseva, engase yenqabe ngokuphelele ukudlulisela lapho ukusetshenziswa kungakudingi neze.

Funda ubufakazi ngaphambi kokukhetha impendulo

Uma kukholakala ukuthi ifayela lokhiye wangasese noma ubunikazi bokusayina obulinganayo buvezile, impendulo ukushintshwa nokuhoxiswa ngohlelo lwenhlangano yakho, kanye nokususa ukwamukelwa kwayo kuyo yonke insizakalo eyayithemba kuyo. Ukususa ikhophi eyodwa yasendaweni akubenzi amakhophi ongawaboni angasebenzi.

Uma ukukhathazeka kungukufinyelela kwe-ejenti kwesikhashana, impendulo incane: misa ukuthunyelwa okungadingekile, buyekeza imihlangano nobunikazi obathintekayo, futhi uvumele umnikazi wesigameko ukuthi anqume ukuthi ukushintshwa kufanelekile yini. Ubufakazi bubalulekile lapha, ngoba ukungabikho kokuthunyelwa okubonakele akufakazi ukuthi akukho kuqinisekisa okusetshenziswe kabi, futhi ukushintsha kwendlela kuphela akusona ukuxilongwa kokhiye webiwe. Bhala ukuthi iyiphi ingxenye eyathenjwa, ukuthi ukudlulisela kwakuvuliwe yini, nokuthi yini eyabonwa ngempela. Bese ukhetha impendulo ehambisana nalowo mbhalo esikhundleni saleyo edramatic kakhulu etholakalayo.

ssh-add -l
ssh -G host.example | grep -i forwardagent

Zisebenzise ngaphambi nangemuva koshintsho ukuze ukuqhathanisa kube nencazelo. Umhlangano owasungulwa ngaphambili ugcina ukuthunyelwa okwanikezwa, kungakhathalise ukuthi izilungiselelo zithini manje.

Izilawuli ezimbili ezingenakushintshwa

Ukuvikela impahla yangasese, ukukhawulela ukuthi ubani angacela ukusayinwa kwayo, nokuqinisekisa ubunikazi bohlangothi olunye kuyizilawuli ezintathu ezihlobene, futhi akukho okunye okungena esikhundleni somunye. Ithimba elisusa ukudlulisela ngaphandle kokuhlola okhiye bomsingathi lilungise ingxenye yenkinga. Ithimba elishintsha ukhiye ngoba indlela yashintsha alilungisanga lutho.

Indawo yokugcina ephazamisekile ingumbuzo wesine, ngoba isofthiwe enamalungelo emshinini wakho ingenza okuningi kakhulu kunokubuka amaphakethe.

Hlukanisa isigameko kulezo zigaba ngaphambi kokuthinta noma yini, futhi unikeze ngasinye umnikazi. Gcina umbhalo omfishane walokho okwathenjwa, okwathunyelwa nokwaqinisekiswa, ngoba lowo mbhalo yiwona owenza ukubuyekezwa okulandelayo kungabizi esikhundleni senye ingxabano. Uma noma isiphi isigaba singaziwa, bhala akwaziwa esikhundleni sokucabanga icala elihle. Umehluko ungowokusebenza, hhayi wezemfundo: unquma ukuthi ushintsha imininingwane yokungena, uhoxisa umhlangano, noma umane uyeke ukudlulisela.
