Okwangoku kunzima ukucinga ukusilela kwethempyutheni yekhompyutheni kwimpilo yethu yemihla ngemihla. Ngezo zonke iindidi zezixhobo eziphathekayo, ngekhompyutheni egcweleyo ngezinye iixesha ayimfuneko nje kuphela kwiofisi, kodwa nasekhaya. Ukusebenza okungaphazamiseki kwezixhobo zekhomputha kunye nokukhuselwa kwayo, kubalulekile ukwazi ukuba yintoni i-firewall kunye nezinye iinkqubo ezongezelelweyo.
I-firewall yenethiwekhi - yintoni na?
Phakathi kwenani elikhulu leprogram, inkqubo yekhompyutheni yokusebenza iquka ukukhuselwa kwangaphambili. I-Firewall okanye i-firewall yinto ekhuselekileyo yesikrini phakathi kwe-intanethi kunye nekhompyutha ngokwayo, eyona isethi yeenkqubo zokufumana nokukhusela ukuhlaselwa kwe-hacker. Njengomthetho, kuguquka ngaphambi kokufikelela kokuqala kwi-intanethi kwaye kunika ithuba lokukhusela ngokufanelekileyo kwedatha yakho. Kuye kumsebenzisi ukugqiba ukuba ngaba ukhubaza i-firewall ngaphambi kokuba uqale umsebenzi.
Nguwuphi umsebenzi weemlilo kunye nezikhuni?
Abasebenzisi abanolwazi kwiikhomputha zabo bahlala bezibuza ukuba kutheni i-firewall iyadingeka. I-firewall enjalo ihlinzeka ngemisebenzi elandelayo:
- ukuqinisekiswa kwedatha evela kwi-Intanethi;
- Ngokuxhomekeka kwisethingi senkqubo, ungaziqhayisa kwikhompyutheni yakho okanye uzivimbele;
- Inkqubo yokukhusela idlulisela kuzo zonke iintlobo zeeprogram ze-hacker - iimbungu, ii-virus, ukuhlaselwa kakubi.
Uwuphi umehluko phakathi kwe-firewall kunye ne-firewall?
Kukho uluvo lokuba umlilo osebenzayo kwaye kulula ukuyilungisa, kodwa kumphathi ngamnye, umbono wakhe kunye namava akhe malunga ne-firewall, kwaye kuya kuba ngcono okanye kubi ngaphezu kwe-firewall. Ngokuqhelekileyo unokuva amagama e-firewall firewall, firewall. La magama adibanisa omnye umsebenzi obalulekileyo kwikhompyutheni-ukukhuselwa kweenkqubo ezifakwe kunye nedatha yomuntu. Ukuze uqonde umbuzo, kuyimfuneko ukwazi ukuba i-firewall kunye ne-firewall. Abanye abasebenzisi abakuboni ukungafani phakathi kwabo, abanye bahlule oku kulandelayo:
- I-firewall (eguqulelwe ukusuka kwisiJamani "njengodonga olukhulu lwamatye") ngokuqhelekileyo yindawo evuliwe yomlilo kwi-Windows operating system.
- I-firewall (ukusuka kwi-firewall yesiNgesi- "udonga lomlilo") - iinkqubo zenkampani yesithathu.
Ngaba ndifuna i-firewall ukuba ndinayo unqulo wesi arab?
Umbuzo odumile kukuba ngaba ufuna i-firewall kwikhompyutheni yakho ukuba inkqubo ye-antivirus ifakwe kuyo. Iingcamango zeengcali malunga nale ngxaki ziyahlukana. Ngakolunye uhlangothi, inkqubo ekhankanywe ngaphambili iqwalasela izicelo eziphuma kwinethiwekhi okanye zidibanisa nayo ngaphandle, kwaye i-antivirus isebenza ngeentlobo ezithile zeefayili ezifakwe kwi-system kwaye zihlola ezo zixhobo xa zivuliwe kwikhompyutha.
Kuyavela ukuba ukusebenza kweenkqubo ezahlukeneyo zokukhusela kuqondiswe kumaqela ahlukeneyo kwimithombo enobungozi. Izindlela zokusebenzisana nabo, njengommiselo, zihluke. Umzekelo, ukuba unayo igciwane leTrojan kwikhompyutheni yakho, i-firewall iya kukhubaza umsebenzi wayo osebenzayo, uyiguqule, kwaye i-antivirus izakuzama ukuyifumana nokuyiphilisa okanye ukuyiphilisa. Ngakolunye uhlangothi, ukufakwa kweenkqubo ezininzi zokukhusela kunokuchaphazela isantya kwenkqubo yonke. Kwezinye iimeko, ukusebenza kwenkqubo yokhuseleko eyongezelelweyo kunokuchaphazela imisebenzi efana neprogram efakwe ngaphambili.
Yiyiphi i-firewall engcono?
Ukukhetha inkqubo ekhuselekileyo yekhompyutheni, kubalulekile ukuqwalasela isantya semfihlo yolwazi olugcinwe kuwo kunye nomsebenzi wokusebenzisa inethiwekhi ye-Intanethi yehlabathi. Ukuze uphendule umbuzo wenzalo, kuyinqweneleka ukuqwalasela imisebenzi yenkqubo nganye yokukhusela. Ukusetyenziswa kwekhompyutheni kungekho rhoqo kwaye kusebenza ngokufanelekileyo kuxhomekeke kwixabiso leprojekthi yesofthiwe ukukhusela. Ngamanye amaxesha i-firewall yamahhala ilungile njengowesifaniso. Kukho inani leempawu omele uzinake ngazo xa ukhetha i-firewall:
- isethi ehlukeneyo yezixhobo zokukhusela;
- unokuthi uvimbele, uphilise okanye ususe i-malware;
- inkqubo yofikeleleko yenkqubo;
- imfuno yokuhlaziya ngezihlandlo;
- imisebenzi eyongezelelweyo yolawulo lwabazali, ukukhutshwa kwezibhengezo zentengiso, ukubeka esweni intengiso ye-intanethi.
I-firewall isebenza njani?
I-firewall okanye i-firewall yinkqubo engavumeli ukuhlaselwa kwe-hacker ukufumana ulwazi oluyimfihlo kwikhompyutha kwaye lukhusele kwiinkqubo ezinobungozi, ii-virus kunye nezibungu. Ngokuqhelekileyo, ezi nkqubo zokhuseleko zihluza i-intanethi yezothutho ngokwezikhowudi ezicwangcisiweyo kubo kwaye ziyeke ukufikelela kwikhompyutha ngaphandle. Ngokuxhomekeke kwisenzo esivunyelwe kwisethingi, iinkqubo ezinolumkiso ziya kukhatywa okanye ziqhekeke.
Kuthekani ukuba i-firewall ivimbela intanethi?
Ngokuqhelekileyo kwenzeka ukuba i-firewall ivimba uxhumano kwi-intanethi. Ngethuba elifanayo, ukufikelela kwezinye izibonelelo kunokukhawulelana, okanye kungabikho nxu lumano kwinethiwekhi. Xa kungabikho namava kula masethingi, kucetyiswa ukuba uqhagamshelane nenkxaso yobugcisa okanye umqulunqo weprogram yomlilo. Ngokuxhomekeke kuhlobo lokukhusela isikrini kunye nezicwangciso zalo, ezi zenzo zilandelayo zinokuba luncedo:
- ukuqalisa kabusha ikhompyutha kunye neprogram yomlilo;
- Yenza kwakhona iskrini somnatha;
- kwisethingi kwesikrini sokukhusela, vula izicelo;
- ukuba kukho i-antivirus, hlola ukuhambelana kwayo kunye ne-firewall.
Ndingayifaka njani isicelo kwi-firewall exceptions?
Ezi nkqubo ezivunyelwe ngumsebenzisi ukuqhuba ziya kuthiwa yi-firewall exceptions. Zifakwe kwiluhlu lwezicwangciso zesikrini somnxeba kwaye zingatshintshwa ngesandla. KwiWindows Firewall, eli nyathelo lenziwa ngolu hlobo lulandelayo:
- Ngokuchofoza iqhosha lokuQala kwicala lokulawula lekhompyutha, kufuneka ufumane ifowuni ye-firewall.
- Kwifestile yayo, khetha "Vumela inkqubo okanye icandelo ukuba liqhube ...".
- Emva koko vula inkinobho ethi "Khetha enye inkqubo", kwaye ukhethe inkqubo efunwayo ukusuka kuhlu lokuhlahla. Ukuba akukho kwiluhlu, itholakala kwiqhosha laseMboniselo.
- Kwi "Iiprogram ezivunyelweyo ..." iwindow, inkqubo efunekayo iya kuboniswa. Ukongeza ii-daws ezihambelana nezikwere zoluhlu, umsebenzisi uneza umzekelo kwi-firewall.
Ndingenza njani i-firewall?
Ukusebenza ngokusisigxina kwesi softhiwe, kufuneka uguqule okokuqala xa uqala ikhompyutha.
