Ni gute wakwizeza umutekano w'ubwishyu mugihe ukoresha serivisi za proxy?

1. Hitamo serivisi yizewe yo gutanga serivisi z'ubuvugizi

1.1 Kugenzura izina ry'umutanga serivisi
Mu guhitamo serivisi ya proxy, kugenzura izina ry'utanga serivisi ni intambwe ya mbere yo kwemeza umutekano w'ubwishyu. Dukurikije amakuru aturuka mu kigo cy’ubushakashatsi ku isoko cya Trustpilot, impuzandengo y'abakoresha batanga serivisi za proxy ni 75%, ariko aya makuru aratandukanye cyane hagati y'abatanga serivisi zitandukanye. Urugero, bamwe mu batanga serivisi za proxy bazwi kandi bemewe, nka ProxyMesh na Luminati, bafite igipimo cyo kunyurwa n'abakoresha kiri hejuru ya 90% na 88%. Aba batanga serivisi akenshi baba bafite amateka meza yo gutanga ibitekerezo ku bakiliya kandi bashobora gutanga serivisi za proxy zihamye kandi zitekanye. Mu buryo bunyuranye, bamwe mu batanga serivisi bato cyangwa batazwi bashobora kuba bafite igipimo cyo kunyurwa n'abakoresha kiri munsi ya 60%, kandi hari ibitekerezo bibi byinshi, nko serivisi zidahamye n'ingaruka zo gusohora amakuru. Kubwibyo, mu gihe bahitamo serivisi za proxy, abakoresha bagomba guha agaciro abatanga serivisi bafite izina ryiza kandi banyurwa n'abakoresha benshi mu nganda kugira ngo bagabanye ibyago bishobora guhura nabyo mu gihe cyo kwishyura.

1.2 Sobanukirwa inyandiko y'umutekano
Gusobanukirwa amateka y’umutekano w’umutanga serivisi za proxy ni ingenzi mu kurinda umutekano w’amafaranga. Nk’uko raporo yakozwe na Netscout, ikigo gikora ubushakashatsi ku mutekano w’ikoranabuhanga ibivuga, hafi 30% by’abatanga serivisi za proxy ku isi bahuye n’ibitero bitandukanye by’umutekano mu mwaka ushize, nko kugaba ibitero bya DDoS no gusohora amakuru. Muri byo, gusohora amakuru ni cyo kibazo gikunze kugaragara cyane mu mutekano, kandi hafi 15% by’abatanga serivisi bahuye n’ibibazo by’amakuru y’abakoresha mu myaka ibiri ishize. Urugero, mu 2024, umutanga serivisi za proxy witwa ProxyHub yashyize ahagaragara aderesi za IP n’amakuru amwe y’ibanga y’abakoresha barenga 100.000 bitewe n’ibibazo by’umutekano, byateje ibibazo bikomeye by’umutekano ku bakoresha. Abatanga serivisi nka StormProxy nta bibazo bikomeye by’umutekano bahuye nabyo mu myaka itanu ishize bitewe no gukoresha ikoranabuhanga rigezweho ryo kurinda umutekano n’uburyo busanzwe bwo kugenzura umutekano. Bityo rero, mu gihe cyo guhitamo serivisi ya proxy, abakoresha bagomba gusuzuma mu buryo burambuye ingamba zo kurinda umutekano z'utanga serivisi, nko kumenya niba hakoreshejwe uburyo bwa "encrypted transmission", niba hari uburinzi bwa "firewall", niba igenzura ry'umutekano rikorwa buri gihe, n'ibindi, kandi bakareba inyandiko zayo z'umutekano za kera kugira ngo birinde guhitamo abatanga serivisi bafite ibyago by'umutekano, kugira ngo barebe neza umutekano w'amafaranga mu gihe bakoresha serivisi za proxy.

2. Koresha uburyo bwo kwishyura buhishe

2.1 Shyira imbere HTTPS connections
Mu gihe ukoresha serivisi za proxy mu kwishyura, guha agaciro urubuga rwo kwishyura rushyigikira HTTPS ni ingamba ikomeye yo kurinda umutekano w'amafaranga. HTTPS ni protocole ya HTTP yizewe ibuza amakuru kwibwa cyangwa guhindurwa mu gihe cyo kohereza amakuru binyuze mu gushyiraho ihuriro rihishe hagati y'umukiriya na seriveri. Dukurikije imibare ituruka mu bigo by'umutekano w'imiyoboro, urubuga rwo kwishyura rukoresha HTTPS rufite ibyago bito bya 80% byo gutakaza amakuru ugereranyije n'urubuga rukoresha HTTP gusa. Urugero, iyo abakoresha binjira muri urubuga rwo kwishyura binyuze muri serivisi za proxy, HTTPS ishobora kwemeza ko amakuru y'abakoresha yo kwishyura (nk'imibare y'amakarita ya banki, ijambo ry'ibanga, nibindi) ahora ahishe mu gihe cyo kohereza amakuru. Nubwo seriveri ya proxy yagabwaho igitero, biragoye ku baterankunga kubona amakuru y'ubwishyu asobanutse. Byongeye kandi, porogaramu nyinshi za mudasobwa zigezweho nazo zitanga ubufasha n'ubufasha ku miyoboro ya HTTPS. Abakoresha bashobora kugenzura niba ihuriro ririho ubu ari HTTPS binyuze mu gice cy'aderesi ya mushakisha kugira ngo bemeze neza umutekano w'ahantu ho kwishyura.

2.2 Kwemeza ko icyemezo cya SSL ari ingenzi
Kwemeza icyemezo cya SSL ni ingenzi mu kwemeza umutekano w’umuyoboro wa HTTPS. Icyemezo cya SSL ni icyemezo cya digitale gitangwa n’ikigo gishinzwe gutanga icyemezo (CA) kigenzura umwirondoro w’urubuga kandi kigatanga ubutumwa buhishe. Mu gihe bakoresha serivisi ya proxy mu kwishyura, abakoresha bagomba kugenzura neza niba icyemezo cya SSL cy’urubuga rwo kwishyura gitangwa na CA yizewe kandi niba icyemezo kiri mu gihe cy’ubuziranenge. Dukurikije ubushakashatsi bwakozwe n’ikigo cy’ubushakashatsi ku mutekano w’ikoranabuhanga, hafi 10% by’urubuga rwo kwishyura rufite icyemezo cya SSL cyarangiye cyangwa inzego zitanga serivisi zitizewe, bishobora gutuma abakoresha bakora ibikorwa byo kwishyura mu buryo butekanye batabizi. Urugero, zimwe muri porogaramu nto zo kwishyura zishobora gukoresha icyemezo cyasinyweho cyangwa zikabona icyemezo kivuye kuri CA zitazwi, kandi umutekano w’izi nyandiko ntushobora kwemezwa. Abakoresha bashobora kureba amakuru arambuye y’icyemezo cya SSL, harimo n’ikigo gishinzwe gutanga serivisi, igihe cy’ubuziranenge bw’icyemezo, izina rya domaine, nibindi binyuze mu miterere y’umutekano ya mushakisha. Niba hagaragaye ibibazo kuri icyo cyemezo, nko gutanga serivisi zitizewe, icyemezo cyarangiye, cyangwa izina rya domaine ritajyanye, abakoresha bagomba guhita bahagarika ibikorwa byo kwishyura kugira ngo birinde ibyago byo gusohora amakuru yo kwishyura.

3. Tegura umuyoboro w’iporeji wizewe

3.1 Shyiraho uburyo bwo kwemeza ijambo ry'ibanga rikomeye
Mu gihe ukoresha serivisi za proxy, gushyiraho uburyo bwo kwemeza ijambo ry'ibanga rikomeye ni inzira y'ingenzi yo kurinda umutekano w'amafaranga yo kwishyura. Amagambo y'ibanga akomeye ashobora gukumira uburenganzira bwo kwinjira mu buryo butemewe no kurinda konti za proxy z'abakoresha n'amakuru yo kwishyura ari muri zo. Dukurikije inama z'inzobere mu by'umutekano w'ikoranabuhanga, ijambo ry'ibanga rikomeye rigomba kuba rifite nibura inyuguti 12, harimo inyuguti nkuru n'inyuguti nto, imibare, n'ibimenyetso byihariye. Urugero, gukoresha ijambo ry'ibanga nka "XyZ3!@#kLmN9" ni umutekano urenze "123456" cyangwa "ijambo ry'ibanga". Dukurikije raporo ya Sophos, ikigo gikora ubushakashatsi ku mutekano w'ikoranabuhanga, ibirenga 60% by'ibibazo by'umutekano w'ikoranabuhanga bifitanye isano n'amagambo y'ibanga adakomeye, kandi gushyiraho ijambo ry'ibanga rikomeye bishobora kugabanya ibyago byo kwibwa kw'amakuru ku kigero kirenga 90%. Byongeye kandi, abakoresha bagomba kwirinda gukoresha ijambo ry'ibanga rimwe muri serivisi nyinshi kugira ngo birinde izindi konti guhura n'akaga igihe konti imwe yakwibwa. Abatanga serivisi za proxy bakunze gutanga ibikoresho byo kumenya imbaraga z'ijambo ry'ibanga kugira ngo bafashe abakoresha gukora amagambo y'ibanga yujuje ibisabwa mu mutekano. Mu gihe biyandikishije kuri serivisi za proxy, abakoresha bagomba gukoresha neza ibi bikoresho kugira ngo barebe ko amagambo y'ibanga yabo akomeye kandi ahamye.

3.2 Guhindura buri gihe IP ya proxy
Guhindura IP ya proxy buri gihe ni ingamba nziza zo kurinda umutekano w'amafaranga. Mu gihe ukoresha serivisi za proxy, guhindura aderesi za IP kenshi bishobora kongera kutamenyekana no kugabanya ibyago byo gukurikiranwa no guterwa. Dukurikije imibare ituruka mu bigo by’ubushakashatsi ku mutekano w’ikoranabuhanga, abakoresha bahindura IP za proxy buri gihe bafite amahirwe make yo guhura n’ibitero bya interineti ku kigero cya 75% kurusha abakoresha badahindura IP. Urugero, bamwe mu batanga serivisi za proxy nka Bright Data batanga serivisi za IP za proxy zihindagurika, kandi abakoresha bashobora gushyiraho inshuro z’impinduka za IP hakurikijwe ibyo bakeneye, kuva ku minota mike kugeza ku masaha make. Ubu buryo bwo guhindura imiterere bushobora gukumira abatera ubugome kubona umwirondoro nyakuri w’abakoresha n’amakuru y’ibikorwa binyuze muri aderesi za IP. Byongeye kandi, gusimbuza IP ya proxy buri gihe bishobora no kwirinda ihungabana ry’ibikorwa riterwa no gufungwa kwa IP ya proxy. Uburyo bumwe bwo kwishyura bushobora kubuza abakoresha bakunze gukoresha IP ya proxy imwe, kandi gusimbuza IP buri gihe bishobora kwemeza ko ibikorwa bikomeza kandi bihamye. Mu gihe uhitamo serivisi za proxy, abakoresha bagomba guha agaciro abatanga serivisi batanga imikorere ya IP ihindagurika, kandi bagashyiraho neza uruziga rwo gusimbuza IP hakurikijwe inshuro zabo bwite z’ibikorwa n’ibyo bakeneye mu mutekano.
