Trivy akuwukiridwanso: Kufalikira kwa GitHub Actions tag zinsinsi zosokoneza

Tsopano akuwukiridwanso: Kufalikira kwa GitHub Actions tag zinsinsi zosokoneza

Chitetezo cha pulogalamu yapaintaneti ndi champhamvu ngati ulalo wake wofooka kwambiri. Kwa magulu osawerengeka achitukuko, ulalo umenewo wakhala zida zomwe amadalira kuti apeze zofooka. Pokhudzana ndi kusintha kwazomwe zidachitika, Trivy, chojambulira chodziwika bwino chopezeka pachiwopsezo chosungidwa ndi Aqua Security, adapezeka ali pachiwopsezo chambiri. Ochita nkhanza asokoneza tagi yamtundu wina (`v0.48.0`) mkati mwankhokwe ya GitHub Actions, ndikulowetsa khodi yopangidwa kuti ibe zinsinsi zachinsinsi pamayendedwe aliwonse omwe adazigwiritsa ntchito. Chochitikachi ndi chikumbutso champhamvu kuti m'malo athu olumikizidwa, kudalirika kuyenera kutsimikiziridwa mosalekeza, osangoganiziridwa.

Anatomy of the Tag Compromise Attack

Uku sikunali kuphwanya malamulo a Trivy, koma kusokoneza mwanzeru makina ake a CI/CD. Owukirawo adalunjika kunkhokwe ya GitHub Actions, ndikupanga mtundu woyipa wa fayilo ya `action.yml` ya tag ya `v0.48.0`. Kayendetsedwe ka ntchito ka wopanga akalozera tagi yeniyeniyi, zomwe zimachitikazo zitha kuyambitsa script yoyipa isanayambitse scan ya Trivy yovomerezeka. Cholembachi chinapangidwa kuti chitulutse zinsinsi - monga zizindikiro zosungira, zizindikiro za opereka mtambo, ndi makiyi a API - ku seva yakutali yoyendetsedwa ndi wowukira. Mkhalidwe wobisika wa kuwukirawu wagona mu tsatanetsatane wake; Madivelopa omwe amagwiritsa ntchito ma tag otetezedwa a `@v0.48` kapena `@main` sanakhudzidwe, koma iwo omwe anakhoma tagi yomwe yasokonezedwa mosazindikira anabweretsa chiopsezo chachikulu pamapaipi awo.

Chifukwa Chomwe Izi Zikuchitika Padziko Lonse la DevOps

Kugwirizana kwa Trivy ndikofunikira pazifukwa zingapo. Choyamba, Trivy ndi chida chachitetezo choyambira chomwe chimagwiritsidwa ntchito ndi mamiliyoni kusanthula zovuta zomwe zili m'matumba ndi ma code. Kuwukira kwa chida chachitetezo kumawononga kudalirika koyambira komwe kumafunikira kuti chitukuko chikhale chotetezeka. Chachiwiri, ikuwonetsa zomwe zikuchulukirachulukira owukira akusunthira "kumtunda," kutsata zida ndi zodalira zomwe mapulogalamu ena amapangidwira. Poyipitsa gawo limodzi logwiritsidwa ntchito kwambiri, amatha kupeza mwayi wolumikizana ndi ma projekiti ambiri akumunsi ndi mabungwe. Chochitikachi chimagwira ntchito ngati kafukufuku wovuta kwambiri pachitetezo cha chain chain, kuwonetsa kuti palibe chida, mosasamala kanthu za mbiri yake, sichingagwiritsidwe ntchito ngati vector yowukira.

"Kuwukiraku kumasonyeza kumvetsetsa kwapadera kwa khalidwe lachitukuko ndi makina a CI / CD. Kuyika chizindikiro cha mtundu wina nthawi zambiri kumaonedwa kuti ndi njira yabwino kwambiri yokhazikika, koma chochitika ichi chimasonyeza kuti chikhoza kuyambitsa chiopsezo ngati mtunduwo wasokonezedwa.

Njira Zaposachedwa Kuti Muteteze Zochita Zanu za GitHub

Kutsatira izi, opanga mapulogalamu ndi magulu achitetezo akuyenera kuchitapo kanthu kuti awumitse mayendedwe awo a GitHub Actions. Kudekha ndi mdani wa chitetezo. Nazi njira zofunika kuzitsatira:

• Gwiritsani ntchito pini ya SHA m'malo mwa ma tag: Nthawi zonse tchulani zochita potengera kudzipereka kwawo kwathunthu (monga `actions/checkout@a81bbbf8298c0fa03ea29cdc473d45769f953675`). Iyi ndi njira yokhayo yotsimikizira kuti mukugwiritsa ntchito mtundu wosasinthika.
• Unikani kagwiridwe ka ntchito kanu: Yang'anani kwambiri chikwatu chanu cha `.github/workflows`. Dziwani zomwe zapanikizidwa pama tag ndikuwasintha kuti azichita ma SHA, makamaka pazida zofunika kwambiri zachitetezo.
• Limbikitsani mbali zachitetezo za GitHub: Yambitsani kuwunika koyenera ndikuwunikanso zochunira za `workflow_permissions`, kuwakhazikitsa kuti aziwerenga pokha kuti muchepetse kuwonongeka komwe kungachitike.
• Yang'anirani zochitika zachilendo: Yambitsani kudula ndi kuyang'anira mapaipi anu a CI/CD kuti muwone maulumikizidwe otuluka mosayembekezereka kapena kuyesa kosavomerezeka pogwiritsa ntchito zinsinsi zanu.

Kumanga Maziko Okhazikika ndi Mewayz

Ngakhale kupeza zida zapayekha ndikofunikira, kulimba mtima kwenikweni kumachokera ku njira zonse zamabizinesi anu. Zochitika ngati kunyengerera kwa Trivy zimawulula zovuta zobisika ndi zoopsa zomwe zili m'maketani amakono. Pulatifomu ngati Mewayz imayankhira izi popereka OS yolumikizana, yokhazikika yomwe imachepetsa kudalirana komanso kuwongolera pakati. M'malo molimbana ndi ntchito khumi ndi ziwiri zosiyana-iliyonse ili ndi njira yakeyake yachitetezo ndikusintha kosinthika-Mewayz imaphatikiza ntchito zazikulu monga kasamalidwe ka projekiti, CRM, ndi kasamalidwe ka zolemba kukhala malo amodzi otetezeka. Kuphatikizika kumeneku kumachepetsa kuukirako komanso kumapangitsa kuti chitetezo chikhale chosavuta, zomwe zimapangitsa kuti magulu aziyang'ana kwambiri zomanga m'malo momangokhalira kumangoyang'ana zovuta zomwe zili pagulu logawika la mapulogalamu. M'dziko limene chizindikiro chimodzi chophwanyidwa chingayambitse kuphwanya kwakukulu, chitetezo chophatikizika ndi ntchito zowonongeka zoperekedwa ndi Mewayz zimapereka maziko olamuliridwa komanso owerengeka kuti akule.
