Daniel Hruska Muchengeti weGedhi ndechimwe chezvinhu zvikuru izvo zvinozoita kutanga kwayo mune iri kuuya OS X Mountain Shumba. Chinangwa chayo (chaizvoizvo) kuchengetedza sisitimu uye kungobvumidza zvikumbiro zvinosangana nemamwe maitiro kuti zvishande. Iyi ndiyo nzira yakanaka yekudzivirira malware?
MuGomo Shumba, iyo "ndege yekuchengetedza" yakakamurwa kuita nhanho nhatu, zvinoti zvikumbiro zvinotenderwa kumhanya kana
- Mac App Store
- Mac App Store uye kubva kune vanozivikanwa vanogadzira
- chero kwakabva
Ngatitorei sarudzo dzega muhurongwa. Kana tikatarisa yekutanga, zvine musoro kuti chikamu chidiki chete chevashandisi ndicho chichasarudza nzira iyi. Kunyangwe paine akawanda uye akawanda maapplication muMac App Store, zviri kure nekuve nemhando yakadai iyo munhu wese anogona kuwana neino sosi chete. Kunyangwe Apple iri kuenda kukiya zvishoma nezvishoma OS X nedanho iri mubvunzo. Nekudaro, isu tinosarudza kusaita zvekufungidzira.
Pakarepo mushure mekuisa iyo system, iyo yepakati sarudzo inoshanda. Asi zvino unogona kuzvibvunza kuti ndiani mugadziri anozivikanwa? Uyu ndiye munhu akanyoresa neApple uye akagamuchira chitupa chavo (Developer ID) chavanogona kusaina mafomu avo. Wese anovandudza anga asati aita zvakadaro anogona kuwana ID yavo vachishandisa chishandiso muXcode. Ehe, hapana anomanikidzwa kutora danho iri, asi vazhinji vanogadzira vanozoda kuona kuti maapplication avo anofamba zvakanaka kunyangwe paOS X Mountain Shumba. Hapana anoda kuti chikumbiro chavo chirambwe nehurongwa.
Zvino mubvunzo ndewekuti, munhu anosaina sei chikumbiro chakadaro? Mhinduro iri mune pfungwa dzeasymmetric cryptography uye siginecha yemagetsi. Kutanga, ngatitsanangure muchidimbu asymmetric cryptography. Sezvinoratidzwa nezita racho, maitiro ese achaitika zvakasiyana pane symmetric cryptography, apo imwe uye imwechete kiyi inoshandiswa pakunyorera uye decryption. Mune asymmetric cryptography, makiyi maviri anodiwa - akavanzika ekunyorera uye eruzhinji kuti anyore. Ndinonzwisisa key inonzwisiswa senhamba refu kwazvo, zvekuti kuifembera nenzira ye "brute force", i.e. nekuedza zvese zvinogoneka zvakatevedzana, zvingatora nguva yakareba zvisingaite (makumi kusvika kuzviuru zvemakore) zvichipihwa simba rekombuyuta remakomputa anhasi. Tinogona kutaura nezve nhamba kazhinji 128 bits uye kureba.
Iye zvino kune yakareruka musimboti wemagetsi siginecha. Anobata kiyi yakavanzika anosaina chikumbiro chake nacho. Kiyi yakavanzika inofanirwa kuchengetedzwa, zvikasadaro chero munhu anogona kusaina data rako (semuenzaniso application). Ne data yakasainwa nenzira iyi, mavambo uye kuvimbika kweiyo data yepakutanga inovimbiswa nemukana wakanyanya kwazvo. Mune mamwe mazwi, iyo application inobva kune uyu mugadziri uye haina kugadziridzwa chero nzira. Ndinosimbisa sei kwakabva data? Kushandisa kiyi yeruzhinji inowanikwa kune chero munhu.
Chii chinozoitika kune chikumbiro chisingaenderane nemamiriro ezvinhu mumakesi maviri apfuura? Pamusoro pekusatangisa application, mushandisi achaunzwa nebhokisi rekunyevera uye mabhatani maviri - Kanzura a Delete. Sarudzo yakaoma, handiti? Panguva imwecheteyo, zvakadaro, iyi inyanzvi yekufamba neApple kune ramangwana. Sezvo mukurumbira wemakomputa eApple uchiwedzera gore rega rega, ivowo vanozopedzisira vava chinangwa chesoftware yakaipa. Asi zvinodikanwa kuti uzive kuti vanorwisa vanozogara vari nhanho imwe pamberi peiyo heuristics uye kugona kweantivirus mapakeji, izvo zvakare zvinoderedza komputa. Saka hapana chinhu chiri nyore sekubvumira chete maapplication akasimbiswa kuti ashande.
Parizvino, zvisinei, hapana ngozi iri pedyo. Ingori shoma shoma yemalware yakaonekwa mumakore achangopfuura. Zvishandiso zvinogona kukuvadza zvinogona kuverengerwa paminwe yerumwe ruoko. OS X haisati yapararira zvakakwana kuti ive chinangwa chekutanga chevanorwisa vanonanga Windows anoshanda masisitimu. Hatingazvinyepere isu kuti OS X haina kudonha. Iri panjodzi senge chero imwe sisitimu yekushandisa, saka zviri nani kudzvanya kutyisidzira mubud. Apple ichakwanisa here kubvisa kutyisidzira kwemalware pamakomputa eApple zvachose nedanho iri? Tichaona mumakore mashoma anotevera.
Sarudzo yekupedzisira yeMuchengeti weGedhi haiunzi chero zvirambidzo zvine chekuita nekwakabva maapplication. Aya ndiwo maziviro atakaita (Mac) OS X kweanopfuura makore gumi, uye kunyange Mountain Shumba haifanire kushandura chero chinhu nezvazvo. Iwe uchiri kukwanisa kumhanyisa chero maapplication. Kune yakawanda yakanakisa yakavhurika sosi software inowanikwa pawebhu, saka zvingave zvinonyadzisa kuzvinyima nazvo, asi nemubhadharo wekudzikisira kuchengetedzeka uye kuwedzera njodzi.
