SELinux kana Security-Enhanced Linux iLuxin kernel yekuchengetedza, iyo inobvumira vashandisi kuwana uye kutarisira mitemo yakawanda yekuchengetedza . Uyu mutsetse unoparadzanisa nekuteerera kwekuchengetedza kusarudzwa kubva kune huwandu hwehutano hwehutano huse. Nokudaro, basa revashandisi veSELinux hazvibvumirwi chaizvo nemabasa evanhu vashandisi chaivo.
Kunyanya, sarudzo inopa basa, zita rekushandisa uye domain kune user. Saka, apo vashandisi vakawanda vangagovana zita rimwechete reSELinux, ruzivo rwekuwana runotungamirirwa kuburikidza neimba, iyo yakagadzirirwa nemitemo yakasiyana. Iyi mitemo inowanzosanganisira mirayiridzo yakananga uye zvibvumirano, zvinoshandiswa nemunhu kuti awane ruzivo rwetsika. Chimiro chepurogiramu chinoumbwa nemapupa kana faira yekuisa mazita, murairo wefaira uye inoshandisa faira. Iwa mafaira akabatanidzwa neshandiswa yeSELinux inogadzirwa, kuumba imwe chete purogiramu yefaira. Iyo iyo faira inotakurwa mujeri, kuitira kuti iite.
Chii chiri SE Android?
Project SE Android kana Kuvandudzika Kwekuchengeteka kweIndaneti kwakavapo kuitira kuti tigadzirise zvikanganiso zvakakosha muhutete hwe Android. Kunyanya kushandisa SELinux muIndaneti, inotarisira kuumba mapurogiramu akachengeteka . Iri purogiramu, zvisinei, haigoni ku SELinux.
SE Android iSELinux; yakashandiswa mukati mayo mafaira ekushanda. Chinangwa chekutarisira kuchengetedzwa kwemapurogiramu munzvimbo dziri kure. Nokudaro, inotsanangura zvakajeka zviito izvo zvibvumirwe zvinogona kutora mukati memamiriro ayo; nokudaro kuramba urongwa husina kutaurwa murairo.
Kunyange zvazvo Android 4.3 yaiva yekutanga kugonesa SELinux kutsigirwa, Android 4.4 aka KitKat ndiyo yekutanga kusunungurwa kuti iite basa rekusimudzira SELinux nekuiisa muchiito. Nokudaro, iwe unogona kuwedzera mune kernel inotsigirwa neSELinux kuIndaneti 4.3, kana iwe unongotarisa kushanda nehutano hwayo. Asi pasi peItro KitKat, sangano iri rakagadzirirwa mukati mekushandiswa kwepasi rose.
SE Android yakanyanya kusimbiswa nekuchengetedzwa, sezvo inogadzirisa kusabvumirwa kusina kubvumirwa uye inodzivirira dambudziko rinobuda kubva kune mapurogiramu. Kunyange zvazvo Android 4.3 inosanganisira SE Android, haikwanise kuigadzirisa nekutadza. Zvisinei, nehuwandu hweIndaneti 4.4, zvingangodaro kuti urongwa huchagoneswa nekusara uye huchazongosanganisa hutano hwakasiyana-siyana kuti hubatsire vatungamiri vehurongwa kuti vatungamirire mitemo yakasiyana-siyana yekuchengetedza mukati me platform.
Shanyira SE Android Project Project peji kuti uzive zvakawanda.
