Key Takeaways
- Cov firewalls tus kheej tuaj yeem pab tiv thaiv koj lub tsev network los ntawm hackers.
- Cov kws tshawb fawb pom muaj teeb meem kev nyab xeeb nrog ntau dua 100 lab cov khoom siv hauv internet txuas.
- Cybercrime tsom rau tib neeg yog qhov teeb meem loj zuj zus vim tias muaj neeg ua haujlwm hauv tsev ntau dua.
Kev tshawb pom tsis ntev los no ntawm cov teeb meem kev nyab xeeb nrog ntau lab ntawm cov khoom siv hauv internet qhia txog qhov xav tau rau cov neeg siv los txiav txim siab txog tus kheej firewall, cov kws tshaj lij hais.
Hauv tsab ntawv tshaj tawm tshiab, cov kws tshawb fawb pom cuaj qhov tsis zoo hauv kev sib txuas lus siv hauv IoT cov khoom siv. Qhov tsis zoo tuaj yeem ua rau Kev Tsis Txaus Siab ntawm Kev Pabcuam (DoS) lossis Chaw Ua Haujlwm Chaw Taws Teeb (RCE) los ntawm hackers. Ntau tshaj 100 lab tus neeg siv khoom, kev lag luam, thiab cov khoom siv IoT tuaj yeem cuam tshuam.
Qhov kev ruaj ntseg tsis zoo tuaj yeem tso cai rau cov neeg nyiag khoom siv cov khoom siv offline lossis tswj lawv nyob deb. Cybercriminals kuj tuaj yeem siv cov teeb meem kev nyab xeeb kom nkag mus tau dav dua rau cov network cuam tshuam.
"Cyber kev hem thawj rau cov neeg nkag mus hauv Is Taws Nem hauv tsev tau nce ntxiv hauv xyoo tas los," Heather Paunet, tus kws tshaj lij kev nyab xeeb ntawm lub tuam txhab cybersecurity Untangle, tau hais hauv kev xam phaj email.
"Thaum cov tuam tsev IT tau sib cav los teeb tsa cov neeg ua haujlwm rau cov chaw ua haujlwm hauv tsev, cov neeg ua phem ua phem tau pom lub sijhawm thiab pib ua kom zoo dua ntawm firewalls uas tsis nyob hauv qhov chaw lossis tsis ua haujlwm txaus."
Firewalls to the Rescue
Firewalls tuaj yeem pab tiv thaiv cov neeg nyiag nkas los ntawm kev siv cov yam tsis zoo uas pom hauv daim ntawv tshaj tawm tsis ntev los no, Dirk Schrader, tus kws tshaj lij kev nyab xeeb ntawm lub tuam txhab cybersecurity New Net Technologies, tau hais hauv kev sib tham email.
Cov firewalls tus kheej tuaj yeem tiv thaiv cov neeg nyiag nkas xa email phem rau koj, nrog rau ib tus neeg dhia ntawm koj qhov kev sib txuas hauv internet, Kris Bondi, CEO ntawm lub tuam txhab kev ruaj ntseg cybersecurity Mimoto, tau hais hauv kev xam phaj email. Lawv kuj tuaj yeem yog cov cuab yeej zoo rau kev tiv thaiv tus kheej.
Cov neeg siv khoom siv hluav taws xob tuaj yeem tuaj yeem los ntawm cov khoom siv hluav taws xob muag lossis tawv tawv, Brian Desmot, CEO ntawm lub tuam txhab cybersecurity iTecs, tau hais hauv kev sib tham email.
A mos firewall feem ntau yog ib qho uas tau teeb tsa rau ntawm lub kaw lus thiab muab qhov yooj yim-rau-siv interface. Lub firewall nyuaj yog ib qho khoom siv nruab rau ntawm cov neeg siv khoom hauv tsev network, thiab ua kom cov tsheb khiav hauv thiab tawm ntawm lub network.
"Cov neeg siv xav tau cov firewalls los xyuas kom meej tias lawv lub kaw lus tuaj yeem thaiv qhov tsis tau thov lossis tsis raug tso cai los ntawm network thiab thov," Desmot ntxiv. "Ib lub firewall tseem tuaj yeem khaws cov kab mob uas tau ua tiav hauv lub computer los ntawm kev xa cov ntaub ntawv rhiab."
Plug hauv Koj Tus Kheej Firewall
Piv txwv li, muaj Firewalla, ib qho khoom siv hluav taws xob nyuaj uas ntsaws rau hauv koj lub router. Nws saib xyuas cov tsheb khiav hauv lub network thiab ceeb toom koj ntawm ib qho app ntawm cov khoom siv hauv tsev tsis zoo. Firewalla thov tseem thaiv cov neeg nyiag nkas thiab tub sab cyber los ntawm kev ua txhaum cai hauv tsev ntse los nyiag cov ntaub ntawv tus kheej.
Ib qho software-raws li firewall yog Bitdefender, uas qhia txog kev thaiv kev nkag mus thiab lim koj lub network tsheb. Nws kuj muaj xws li webcam thiab microphone tiv thaiv kom tsis txhob eavesdropping.
Ib yam kev tawm tsam ntau tshaj plaws uas firewalls pab tiv thaiv yog kev tsis lees paub kev pabcuam (DDoS) kev tawm tsam, Tom Kirkham, CEO ntawm lub tuam txhab cybersecurity IronTech Security, tau hais hauv kev xam phaj email. DDoS tawm tsam yog kev tawm tsam tsom rau cov vev xaib uas muaj kev pabcuam online.
"Lawv suav hais tias yog kev tawm tsam tsis zoo qhov twg cybercriminals tawm tsam ib qho kev pabcuam online los ntawm kev ua kom lub vev xaib muaj zog," nws hais."Hackers bombard lub vev xaib nrog ntau ntawm kev khiav tsheb hauv online, tawm hauv lub server lossis network qhov twg nws tsis tuaj yeem tswj xyuas kev khiav tsheb."
Rau kev tiv thaiv zoo tshaj plaws, cov kev daws teeb meem hluav taws xob yuav tsum tiv thaiv koj lub network, nrog rau cov khoom siv thiab cov neeg siv, Paunet hais.
Ib lub firewall tseem tuaj yeem khaws cov kab mob uas tau ua tiav hauv lub computer los ntawm kev xa cov ntaub ntawv rhiab.
Lub firewall yuav tsum muaj kev tiv thaiv kab mob; kev tiv thaiv kev hem thawj, kom tsis txhob ua phem rau cov servers nrog lub koob npe tsis zoo los ntawm kev tso cai hauv lub network; thiab kev tiv thaiv los ntawm ransomware thiab nyem rau ntawm qhov txuas tsis zoo. Nws kuj yuav tsum suav nrog kev lim dej hauv web uas tiv thaiv cov neeg siv los ntawm kev nyem rau ntawm qhov txuas uas tuaj yeem ua tiav qee yam ntawm lawv cov khoom siv.
Txawm lawv qhov zoo, firewalls tsis muaj kev tiv thaiv zoo. "Lub firewalls tus kheej tsis zoo rau kev tiv thaiv malware tawm tsam, txawm li cas los xij," Bondi hais. "Malware tuaj yeem ncav cuag lub kaw lus los ntawm qhov kev pabcuam cuam tshuam hauv daim ntawv ntawm cov ntaub ntawv ntseeg siab."
Bondi pom zoo kom siv tus kheej VPN tsis yog firewall. "Ib lub VPN encrypts koj cov kev sib txuas lus thiab npog koj cov dej num 'qhov chaw. Xav tias nws yog kev khiav hauj lwm incognito nrog ntxiv kev ruaj ntseg thiab muaj peev xwm sau npe qhov chaw koj yuav tshwm sim nyob," Bondi hais.
