Anyamata abwino ndi Anyamata Oipa Akugwiritsa Ntchito Njirayi Kuti Atsegule Maiko
Momwemo mukufunira kuletsa ndi kuyendetsa magalimoto omwe amaloledwa mu intaneti kapena makompyuta anu. Izi zikhoza kuchitika m'njira zosiyanasiyana. Njira ziwiri zikuluzikulu ndizoonetsetsa kuti mapepala osafunika pa kompyuta yanu sakhala otseguka kapena omvetsera chifukwa chogwirizana ndi kugwiritsa ntchito firewall - kaya pa kompyuta yokha kapena pa intaneti - kuyimitsa magalimoto osaloledwa.
Poyendetsa magalimoto ndi kugwiritsa ntchito malamulo a firewall pogwiritsa ntchito zochitika zomwe zingathe kukhazikitsa "chinsinsi" chomwe chidzatsegulira chipata ndikukutulutsani ku firewall. Ngakhale kuti palibe machweti angakhale otseguka panthawiyo, njira zingapo zogwirizanitsira mayendedwe otsekedwa angapangitse munthu kuyamba kutsegula doko kuti azilankhulana.
Mwachidule, mukanakhala ndi ntchito yothamanga pa chipangizo chomwe chikulingalira chomwe chikanati chiwonetsetse ntchito yochepetsera - makamaka mwa kuyang'anira zipika za moto . Utumiki udzafunika kudziwa "chinsinsi chogwedezeka" - chitsanzo chinalephera kuyesa kugwiritsira ntchito mayendedwe 103, 102, 108, 102, 105. Ngati ntchitoyo itakumana ndi "chinsinsi chogogoda" mu dongosolo lolondola ndiye kuti idzasintha malamulo a firewall kutsegula malo otsegulira kuti alowere kutali.
Tsoka la olemba pulogalamu yaumbanda padziko lapansi (mwatsoka - mudzawona chifukwa chake mumphindi) ayamba kugwiritsa ntchito njirayi kuti atsegule maulendo oponderezedwa. Kwenikweni, m'malo motsegulira madoko omwe ali kutali kwambiri omwe amawonekera mosavuta ndi owoneka, Trojan imabzalidwa yomwe imayang'anitsitsa magalimoto. Pomwe "chinsinsi chikugogoda" chikutsatiridwa kuti pulogalamu ya pulogalamu yaumbanda idzadzutsa ndi kutsegulira malo okonzedweratu a backdoor, kulola kuti owukirayo athe kuntchito.
Ndanenapo kuti izi zikhoza kukhala chinthu chabwino. Chabwino, kutenga kachilombo koyambitsa matenda a mtundu uliwonse sikungakhale chinthu chabwino. Koma, monga momwe zikuyimira pakali pano kachilombo kapena nyongolotsi imayamba kuyambira ma doko ndipo manambala a phukusiwa amadziwika kuti anthu omwe ali ndi kachirombo ka HIV amakhala otseguka kuti awonongeke ndi wina aliyense - osati wolemba pulogalamu ya pulojekiti imene inatsegula kumbuyo. Izi zimachulukitsa zovuta zowonjezereka kapena kachilombo kamene kamakhalako kamene kakugwiritsidwa ntchito pazambuko zotseguka zomwe zimayambitsidwa ndi loyambalo yoyamba.
Pogwiritsa ntchito malonda a backdoor omwe amafunika kuti "chinsinsi chigwedeze" kuti mutsegule wolemba mabuku wa pulogalamu ya malware akubisa chinsinsi cha backdoor. Apanso, izi ndi zabwino komanso zoipa. Zabwino chifukwa Tom, Dick ndi Harry akuwopsya wannabe sangakhale phokoso lofufuza kuti apewe zovuta zomwe zimachokera pa doko lotsegulidwa ndi malware. Zoipa chifukwa ngati nthawi yayitali simudziwa kuti ilipo mwina kapena apo sikungakhale njira yophweka yozindikiritsira kuti muli ndi malo osungira kumbuyo pakhomo lanu kuyembekezera kudzutsidwa ndi doko logwedezeka.
Chinyengo ichi chikhonza kugwiritsidwanso ntchito ndi anyamata abwino monga momwe tafotokozera m'nyuzipepala ya Crypto-Gram yochokera ku Bruce Schneier. Kwenikweni wolamulira akhoza kutseka kwathunthu dongosolo - kulola palibe magalimoto kunja koma kuyambitsa ndondomeko yogwedeza doko. Pogwiritsira ntchito "chinsinsi chogogoda" woyang'anira adzatha kutsegula piritsi pamene kuli kofunikira kukhazikitsa chiyanjano chakutali.
Zikuwoneka kuti ndizofunikira kuti musunge chinsinsi cha "chinsinsi chobisika". Kwenikweni, "chinsinsi chongogwedeza" chidzakhala "mawu achinsinsi" a mitundu yomwe ingalole kuti munthu asadziwe mosavuta.
Pali njira zingapo zokhazikitsira khomo logwedezeka ndikuonetsetsa kuti umphumphu wachitsulo ukugwedezeka - koma pakadalibe ubwino ndi kuwononga kugwiritsa ntchito chida chogwiritsira ntchito chitetezo pa intaneti. Kuti mudziwe zambiri, onani Mmene Mungayendetsere: Port Kukugwedezani pa LinuxJournal.com kapena zina zogwirizana ndi ufulu wa nkhaniyi.
Zosindikiza za Mkonzi: Nkhaniyi ndi yokhudzana ndi cholowa ndipo inasinthidwa ndi Andy O'Donnell pa 8/28/2016.
