Ngokuyisisekelo, kuyisisekelo se-DevSecOps evikelekile. Zonke izinhlelo ezivikelekile (kungakhathaliseki ukuthi CI/CD pipeline, ukuthunyelwa kwamafu, noma enterprise (i-application) ihlala ithembele kulesi sici esibalulekile. Yingxenye engabonakali egcina idatha iphephile, iqinisekisa ubuqiniso, futhi iqinisekise ukuthi abasebenzisi noma izinsizakalo ezigunyaziwe kuphela ezingafinyelela ulwazi olubucayi. Ukwazi ukuthi iyini ukhiye wokubethela nokuthi ungawuphatha kanjani ngempumelelo akuyona nje ingxenye yomsebenzi wabo bonke ochwepheshe be-DevSecOps; kubalulekile ekwakheni. ukuphepha kuzo zonke izigaba zomjikelezo wokuphila kwesofthiwe.
Ngakho-ke Iyini Inkinobho Yokubethela Futhi Kungani Kubalulekile? #
Kuwuchungechunge lwama-bits asetshenziswa ama-algorithms e-cryptographic ukuguqula idatha ibe yifomethi evikelwe. Uma sikhuluma ngokubethela ukhiye, sibhekisela enkambisweni ehlanganisa idatha ukuze kube ukhiye ofanele kuphela ongayibuyisela esimweni sayo sokuqala.
Cabanga ngakho njengegama lokungena eliyingqayizivele elikhiya futhi livule idatha yakho. Ngaphandle kwalo, ulwazi olubethelwe cishe alufundeki (ngisho noma othile ekwazi ukulivimba).
Lezi zikhiye zivikela yonke into: izimfihlo ze-API, iziqinisekiso zesizindalwazi, izinto zokwakha, kanye nedatha yokucushwa ebucayi. Kusukela ekuvikeleni izimfihlo kumaqoqo e-Kubernetes kuya ekubetheleni amabhakede e-S3 noma CI/CD Amathokheni, konke kuqala ngemikhuba efanele yokubethela ukhiye kanye nokhiye womsindo.
Isebenza Kanjani I-Key Encryption? #
Ezingeni eliphezulu, ukubethela kuhlale kuhilela izinyathelo ezimbili:
- Ukubethela: Idatha engenalutho iguqulwa ibe yi-ciphertext kusetshenziswa ukhiye othile wokubethela.
- Ukususa ukubethela: I-ciphertext iguqulwa ibe yidatha efundekayo kusetshenziswa ukhiye ofanayo noma ohambisanayo.
Le ndlela ingalandela amamodeli amabili okubethela okhiye, okulingana nokungalingani, ngalinye linezindlela zalo zokushintshana. Manje ake singene kokulingana!
Ukubethela kokhiye we-Symmetric #
Ekubetheleni okulinganayo, ukhiye ofanayo wokubethela usetshenziselwa ukubethela nokususa ukubethela. Kuyashesha, kusebenza kahle ngokwezibalo, futhi kufanelekile ukuvikela amasethi edatha amakhulu noma ukuxhumana kwangaphakathi lapho izinhlangothi zombili sezivele zabelana ngemfihlo ethembekile.
Kodwa-ke, inselele enkulu lapha ukusatshalaliswa kokhiye okuphephile. Uma othile ebamba ukhiye, angawususa wonke idatha ehlobene nawo. Yingakho amaqembu e-DevSecOps kumele aphathe ukulethwa nokugcinwa kokhiye ngokucophelela okukhulu, ikakhulukazi uma esebenza ngokuzenzakalelayo pipelinenoma izindawo ezisatshalaliswe.
Ama-algorithm avamile ahambisanayo afaka i-AES (Advanced Encryption) Standard) kanye ne-3DES (Triple DES). Lezi zivame ukusetshenziselwa ukuvikela izithombe zesitsha, ukuxhumana kwesevisi, noma idatha egcinwe ngaphakathi kwesitoreji samafu.
Nakuba ukubethela okulinganayo kulula ukukusebenzisa, ukuphepha kwakho kuncike ngokuphelele ekugcineni leyo mfihlo eyodwa yesihluthulelo. Ake siqhubeke nokubethela okulinganayo!
Ukubethela Okungalingani: Ukubethela Kokhiye Womphakathi vs Oyimfihlo #
Imodeli yokubethela ukhiye womphakathi vs oyimfihlo (eyaziwa nangokuthi ukubethela okungalingani) ixazulula inkinga yokusabalalisa ngokusebenzisa okhiye ababili esikhundleni soyedwa.
- Ukhiye womphakathi wabelwana ngokukhululeka futhi usetshenziselwa ukubethela idatha
- Ukhiye oyimfihlo ugcinwa uyimfihlo futhi usetshenziselwa ukuwubhala phansi
Le ndlela iqinisekisa ukuthi noma ngabe ukhiye womphakathi uveziwe, akekho ongabhala ngemfihlo idatha ngaphandle kokhiye oyimfihlo ohambisanayo. Ku-DevSecOps, ukubethela komphakathi vs okuyimfihlo kusekela ukuqinisekiswa kwe-SSH, izitifiketi ze-TLS, kanye nokusayina kwephakheji okuphephile.
Uma ucindezela ikhodi ku-GitHub nge-SSH noma usungula uxhumano lwe-HTTPS, ukubethela komphakathi noma okuyimfihlo yikho okwenza lokho kushintshaniswa kuphephe. Kuvumela ukuqinisekiswa kobunikazi, ubuqotho bomyalezo, kanye nobumfihlo bedatha, konke ngaphandle kokwabelana ngezimfihlo kuwo wonke amanethiwekhi.
Ama-algorithm afana ne-RSA kanye ne-Elliptic Curve Cryptography (ECC) ayinsika yokubethela ukhiye womphakathi vs oyimfihlo. Ahamba kancane kunezindlela ezilinganayo kodwa abalulekile ekwakheni ukwethembana phakathi kwezinsizakalo noma abasebenzisi ngaphambi kokushintshanisa okhiye abalinganayo ngokushesha.
Ukuphathwa Okuyinhloko: Isendlalelo Sokuphepha Esinganakwa #
Ukuqonda ukuthi iyini ikhi yokubethela akwanele; ukuphatha okhiye ngokuphephile kuyinselele yangempela. Imikhuba emibi yokubethela ingaholela ekuphulweni okukhulu kwemithetho, ngisho noma i-algorithm yokubethela ngokwayo ingenaphutha.
1. Ukukhiqiza Izihluthulelo #
Dala okhiye njalo usebenzisa ama-generator ezinombolo ezingahleliwe avikelekile nge-cryptographically (ama-CSPRNG). Okhiye ababikezelwayo noma okhiye abasetshenziswe kabusha balimaza uhlelo lonke.
2. Isitoreji Sezihluthulelo #
Ungalokothi ufake ikhodi yokhiye wokubethela kuhlelo lwakho lokusebenza, isithombe sesitsha, noma indawo yokugcina. Sebenzisa izinhlelo zokuphatha ukhiye we-cloud-native (i-AWS KMS, i-Azure Key Vault, i-Google Cloud KMS) noma amathuluzi okuphatha izimfihlo azinikele njenge-HashiCorp Vault.
3. Ukuzungezisa Ukhiye #
Okhiye kumele bajikeleziswe njalo. Ukujikeleza okuzenzakalelayo kunciphisa ukuvezwa futhi kuqinisekisa ukuhambisana nezinhlaka ezifana ne-PCI-DSS, ISO 27001, kanye ne-GDPR.
4. Ukulawula Ukufinyelela Okuyinhloko #
Hlanganisa isitoreji sakho sokhiye nezinqubomgomo ze-IAM noma ze-RBAC. Amasevisi noma abasebenzisi abadinga ngempela ukhiye kuphela okufanele bakwazi ukufinyelela kuso.
5. Ukubhujiswa Okuyinhloko #
Uma okhiye bengasadingeki, kumele babhujiswe ngokuphephile. Ukugcina okhiye abangasetshenziswanga kungadala ama-vector okuhlasela athule ezindaweni ze-DevSecOps ezihlala isikhathi eside.
Ukuphathwa kokubhala ngemfihlo okusebenzayo akuyona nje indlela engcono kakhulu; kuyisiqondiso esiyimpoqo samaketanga okuhlinzeka ngesofthiwe yesimanje.
Okhiye Bokubethela Ku-DevSecOps Workflows #
Ku-DevSecOps, bahlala endaweni lapho kuhlangana khona intuthuko, ukuphepha, kanye nokusebenza. Nansi indlela abaziphatha ngayo ngokoqobo:
- Ukuphathwa Kwezimfihlo: Amathokheni e-API, izitifiketi, kanye neziqinisekiso kufanele konke kubethelwe kusetshenziswa izindlela zokubethela ukhiye ngaphambi kokufakwa ku- pipelinenoma izindawo zesikhathi sokusebenza.
- Ingqalasizinda njengeKhodi: Gwema ukufaka okhiye abangahluziwe kumathempulethi e-Terraform, Ansible, noma e-Helm. Kunalokho, babhekisele ngokuphephile ezitolo zokhiye eziphethwe.
- CI/CD Pipelines: Jikelezisa okhiye bokwakha nokufaka njalo, bese usebenzisa iziqinisekiso zesikhashana ezindaweni zesikhashana.
- Ukucwaningwa kwamabhuku nokuhambisana: Landelela ukusetshenziswa kokhiye kanye nemicimbi yokujikeleza. Ukuhlola ukuthi ubani ofinyelele noma ojikelezise ukhiye wokubethela kusiza ekutholeni ukusetshenziswa kabi kusenesikhathi.
Ithimba le-DevSecOps elivuthiwe liphatha ukuphathwa kokhiye wokubethela njengengxenye yendwangu yalo yokwenza izinto ngokuzenzakalela, hhayi njengento ecatshangwa kamuva.
Ukubethela Ukhiye Womphakathi vs Oyimfihlo Ezimweni Zangempela #
Ukuze uqonde kangcono ukubethela komphakathi noma okuyimfihlo, cabanga ukuthi kuyini kakade okunika amandla ingqalasizinda yakho:
- Izitifiketi ze-TLS/SSL: Vikela ithrafikhi yewebhu usebenzisa ukubethela okungalingani phakathi kwamakhasimende namaseva.
- Ukuqinisekiswa kwe-SSH: Abathuthukisi baqinisekisa ngokusebenzisa ukubethela kokhiye womphakathi noma oyimfihlo ngaphandle kokudlulisa amaphasiwedi.
- Amasiginesha Edijithali: Izinto zobuciko zesofthiwe nekhodi commitAma-s angasayinwa kusetshenziswa okhiye abayimfihlo, okuqinisekisa ubuqiniso ngesikhathi sokufakwa.
- Ukubethela nge-imeyili: Izinhlelo ezifana ne-PGP zisebenzisa ukubethela komphakathi kanye nokwangasese ukuze zivikele okuqukethwe kwemilayezo kusukela ekuqaleni kuze kube sekugcineni.
Izibonelo ngasinye siqokomisa indlela okhiye bokubethela abalukwa ngayo ngokujulile isu lemisebenzi yokuphepha yansuku zonke.
Ngakho-ke, Uyazi Yini Ukuthi Kungani Zibalulekile Ekuphepheni kwe-DevSecOps? #
Uma kukhona umqondo owodwa okufanele wonke unjiniyela wezokuphepha awufake ngaphakathi, yilokho okuyi-encryption key kanye nendlela abaphathi bayo abangayenza noma abaphule ngayo ukuphepha ngezinga eliphezulu. Ubumfihlo bedatha ebucayi, ubuqotho bekhodi pipelines, kanye nobuqiniso bokusetshenziswa okuzenzakalelayo konke kuncike ekubethelweni okwenziwe kahle.
Ngaphandle kokulawula ukhiye okuhlelekile, ngisho nama-algorithms aqinile okubethela awasizi ngalutho. Ukhiye ovuzayo noma ongaphathwanga kahle ungadalula idatha yamakhasimende, izinhlelo zokunciphisa ijubane, futhi uqede ukwethembana ekusetshenzisweni okuzenzakalelayo.
Imikhuba eqinile yokubethela yomphakathi neyangasese, kuhlanganiswe nokuhlola okuqhubekayo kanye nokujikeleza okuzenzakalelayo kokhiye, kudala ungqimba lokuzivikela oluqinile oluhambisana kahle nezimiso ze-DevSecOps, ukuphepha ngokuklama kanye nokuzenzakalelayo.
Ngamafuphi … #
Ukhiye Wokubethela ungaphezu nje kwengxenye yezinto ezifihliwe. Njengoba sesibonile, uyisisekelo sokulethwa kwesofthiwe okuphephile.
Ukufingqa:
- Ukwazi ukuthi iyini kwenza amaqembu e-DevSecOps aqonde ukuthi idatha ivikelwe kanjani kusukela ekuqaleni kuze kube sekupheleni.
- Imikhuba efanele yokubethela ukhiye iqinisekisa ukuthi ukuphepha akuxhomekile ekusithekeni kuphela, kodwa ekulawuleni okuhlelekile kanye nokwenza ngokuzenzakalela.
- Ukusebenzisa amamodeli okubethela okhiye womphakathi vs oyimfihlo kuthuthukisa ubuqiniso, ubuqotho, kanye nokwethembana kuyo yonke indawo pipelines.
Ku-DevSecOps, ukuvikela okhiye kubalulekile ekuvikeleni konke okuncike kukho, okuhlanganisa ikhodi yakho, ingqalasizinda, futhi ekugcineni, idumela lenhlangano yakho.
