I-Firewall: iyini futhi yenzani?

Namuhla noma umsebenzisi wekhompyutha ongenalwazi uyazi ukuthi i- World Wide Web igcwele zonke izinhlobo zokusongela. Okuqala ukuza engqondweni kungama-virus namaTrojans, kodwa akufanele ukhohlwe ukuthi kukhona ukuhlaselwa kwenethiwekhi kanye nezinye "umsindo", ongakunikeza izinkinga eziningi.

Usizo lokubhekana nalezi zenzakalo ezibizwa nge-Firewall. Kuyini futhi kungani kuyasiza kangaka?

Ukucindezeleka komlando

Kwenzeke ukuthi okokuqala leli gama laphakama emvelweni wabacimi bomlilo. "I-Firewall" noma "I-Fire Wall" babibiza ngomlilo, owaqondiswa emthonjeni womlilo.

Lapho imithombo emibili yelangabi ihlangene, ibuye iphelelane. Kodwa lena akuyona i-Firewall. Kuyini, ukwahlulela kusuka esikhundleni somsebenzisi wekhompyutha?

Ukulungiswa kwemfundiso

Lokhu kuyinkimbinkimbi yesofthiwe noma i-hardware eyinkimbinkimbi ehlunga yonke ithrafikhi yenethiwekhi, ekhomba umsebenzi ononya ngokusizwa kweqoqo lemithetho elifakwe kuwo. Ngaphezu kwalokho, abahlaziyi be-heuristic kanye nezinhlelo ze- "sandbox" zisetshenziselwa ukuthola nokuvimbela izinhlelo ezingase zibe nenhlekelele.

Uma ukukhuluma kulula

Uma sihumusha konke okushiwo ngenhla kumafomu ajwayelekile, i-Firewall (esiyifunde yona) uhlelo olukhethekile olulawula ezinye izinhlelo zokusebenza kukhompyutheni.

Kodwa ilawula indlela i-antivirus engayisebenzisi ngayo, kodwa ngokombono wokuvimbela noma ukuvumela ukufinyelela kwinethiwekhi. Lena yi-Firewall. Kuyini, uma ukhuluma ngomsebenzisi ojwayelekile we-PC, obani lokhu kuziphatha kwezinhlelo akuthandi nakancane?

Kuyini?

Lesi simo sengqondo ngokuphepha kwabo siqu sinezinkinga. Ngisho noma uqinisekile ukuthi ukweba kusuka kukhompyutha yakho akusekho lutho, ukuthi abaduni ababi abathandeki amafayili akho, ngakho konke lokhu akukona iqiniso ngokuphelele.

Unayo ikhasi ekuxhumaneni nomphakathi? Futhi inombolo yefoni oyifaka njalo ukuqinisekisa noma yini? Ngakho-ke, yonke le mininingwane emakethe yesimanje "sesithunzi" inenani elithile. Ngakho inzuzo ingatholakala kunoma yimuphi umsebenzisi ongenandaba.

Bawuthanda ngani?

Ngokuvamile, emakethe ye-anti-virus nezinye izinhlelo zokusebenza zokuzivikela kuze kube yimanje, indlu egcwele: ngoba ukukhiqizwa kwayo kuthathe ngisho nezinkampani ezingakaze zenze okufanayo ngaphambili. Yiqiniso, ukuthi uma ukhetha owodwa kufanele ugxile kuphela kwimikhiqizo yamafemu ahlonishwayo ahloniphekile.

Zisatshalaliswa njengezinqwaba nge-OS, futhi ngokwehlukile. Lezi zinsuku zihlukaniswe zibe yimikhiqizo ye-software emele (i-Outpost) kanye "ne-appendage" ku-antivirus. Isibonelo esicacile yi-Norton Internet Security, Kaspersky Internet Security kanye nezinye "abalindi".

Uma usebenzisa uhlelo lokusebenza kusuka kwinkampani eyodwa ebonakalayo evela ku-Redmond, cishe awudingi ukulungisa i-Firewall. I-Windows ivikelekile ngaphakathi kwalesi sigaba, futhi ezinguqulweni zakamuva ze-OS ukusebenza kwayo kwande kakhulu.

Njengomthetho, izinqola ezakhelwe ngaphakathi ziwanele ukubonisa izinsongo ezinkulu kakhulu. Uma ufaka isofthiwe kumkhiqizi wesithathu, le firewall ivuliwe ngokuzenzakalelayo.

Kodwa kwenzeka ukuthi ngemuva kokukhipha i-antivirus noma olunye uhlelo olufanayo, ukuvikelwa okuzakhelwe akuvuli ngokuzenzakalelayo. Ngakho iphi i-Firewall, engayikuyeka ukumisa kabusha? Udinga ukuyihlola iphaneli yokulawula, lapho kuthiwa "iWindows Firewall".
